Canvas Breach Disrupts Schools & Colleges Nationwide

8 May 2026 at 04:58

An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service’s login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions.

A screenshot shared by a reader showing the extortion message that was shown on the Canvas login page today.

Canvas parent firm Instructure responded to today’s defacement attacks by disabling the platform, which is used by thousands of schools, universities and businesses to manage coursework and assignments, and to communicate with students.

Instructure acknowledged a data breach earlier this week, after the cybercrime group ShinyHunters claimed responsibility and said they would leak data on tens of millions of students and faculty unless paid a ransom. The stated deadline for payment was initially set at May 6, but it was later pushed back to May 12.

In a statement on May 6, Instructure said the investigation so far shows the stolen information includes “certain identifying information of users at affected institutions, such as names, email addresses, and student ID numbers, as well as as messages among users.” The company said it found no evidence the breached data included more sensitive information, such as passwords, dates of birth, government identifiers or financial information.

The May 6 update stated that Canvas was fully operational, and that Instructure was not seeing any ongoing unauthorized activity on their platform. “At this stage, we believe the incident has been contained,” Instructure wrote.

However, by mid-day on Thursday, May 7, students and faculty at dozens of schools and universities were flooding social media sites with comments saying that a ransom demand from ShinyHunters had replaced the usual Canvas login page. Instructure responded by pulling Canvas offline and replacing the portal with the message, “Canvas is currently undergoing scheduled maintenance. Check back soon.”

“We anticipate being up soon, and will provide updates as soon as possible,” reads the current message on Instructure’s status page.

While the data stolen by ShinyHunters may or may not contain particularly sensitive information (ShinyHunters claims it includes several billion private messages among students and teachers, as well as names, phone numbers and email addresses), this attack could hardly have come at a worse time for Instructure: Many of the affected schools and universities are in the middle of final exams, and a prolonged outage could be highly damaging for the company.

The extortion message that greeted countless Canvas users today advised the affected schools to negotiate their own ransom payments to prevent the publication of their data — regardless of whether Instructure decides to pay.

“ShinyHunters has breached Instructure (again),” the extortion message read. “Instead of contacting us to resolve it they ignored us and did some ‘security patches.'”

A source close to the investigation who was not authorized to speak to the press told KrebsOnSecurity that a number of universities have already approached the cybercrime group about paying. The same source also pointed out that the ShinyHunters data leak blog no longer lists Instructure among its current extortion victims, and that the samples of data stolen from Canvas customers were removed as well. Data extortion groups like ShinyHunters will typically only remove victims from their leak sites after receiving an extortion payment or after a victim agrees to negotiate.

Dipan Mann, founder and CEO of the security firm Cloudskope, slammed Instructure for referring to today’s outage as a “scheduled maintenance” event on its status page. Mann said Shiny Hunters first demonstrated they’d breached Instructure on May 1, prompting Instructure’s Chief Information Security Officer Steve Proud to declare the following day that the incident had been contained. But Mann said today’s attack is at least the third time in the past eight months that Instructure has been breached by ShinyHunters.

In a blog post today, Mann noted that in September 2025, ShinyHunters released thousands of internal University of Pennsylvania files — donor records, internal memos, and other confidential materials — through what the Daily Pennsylvanian and other outlets later determined was, in part, a Canvas/Instructure-mediated access path.

“Penn was the named victim,” Mann wrote. “Instructure was the mechanism. The incident was treated as a Penn-specific story by most of the national press and quietly handled by Instructure as a customer-specific matter. That framing was wrong then. It is dramatically more wrong in light of the May 2026 events, which now look like the planned escalation of an attack pattern that ShinyHunters had been working against Instructure’s environment for at least eight months prior. The September 2025 Penn breach was the proof of concept. The May 1, 2026 incident was the production run. The May 7, 2026 recompromise was ShinyHunters demonstrating publicly that the May 2 ‘containment’ did not happen.”

In February, a ShinyHunters spokesperson told The Daily Pennsylvanian that Penn failed to pay a $1 million ransom demand. On March 5, ShinyHunters published 461 megabytes worth of data stolen from Penn, including thousands of files such as donor records and internal memos.

ShinyHunters is a prolific and fluid cybercriminal group that specializes in data theft and extortion. They typically gain access to companies through voice phishing and social engineering attacks that often involve impersonating IT personnel or other trusted members of a targeted organization.

Last month, ShinyHunters relieved the home security giant ADT of personal information on 5.5 million customers. The extortion group told BleepingComputer they breached the company by compromising an employee’s Okta single sign-on account in a voice phishing attack that enabled access to ADT’s Salesforce instance. BleepingComputer says ShinyHunters recently has taken credit for a number of extortion attacks against high-profile organizations, including Medtronic, Rockstar Games, McGraw Hill, 7-Eleven and the cruise line operator Carnival.

The attack on Canvas customers is just one of several major cybercrime campaigns being launched by ShinyHunters at the moment, said Charles Carmakal, chief technology officer at the Google-owned Mandiant Consulting. Carmakal declined to comment specifically on the Canvas breach, but said “there are multiple concurrent and discrete ShinyHunters intrusion and extortion campaigns happening right now.”

Cloudskope’s Mann said what happens next depends largely on whether Instructure’s customers — the universities, K-12 districts, and education ministries paying for Canvas — choose to apply pressure or absorb the breach quietly.

“The history of education-vendor incidents suggests the path of least resistance is the second one,” he concluded.

Update, May 8, 11:05 a.m. ET: Instructure has published an incident update page that includes more information about the breach. Instructure said its Canvas portal is functioning normally again, and that the hackers exploited an issue related to Free-for-Teacher accounts.

“This is the same issue that led to the unauthorized access the prior week,” Instructure wrote. “As a result, we have made the difficult decision to temporarily shut down Free-for-Teacher accounts. These accounts have been a core part of our platform, and we’re committed to resolving the issues with these accounts.”

Instructure said affected organizations were notified on May 6.

“If your organization is affected, Instructure will contact your organization’s primary contacts directly,” the update states. “Please don’t rely on third-party lists or social media posts naming potentially affected organizations as those lists aren’t verified. Instructure will confirm validated information through direct outreach to all affected organizations.”

Update, May 11, 10:16 p.m. ET: Instructure posted an update saying they paid their extortionists in exchange for a promise to destroy the stolen data. “The data was returned to us,” the update reads. “We received digital confirmation of data destruction (shred logs). We have been informed that no Instructure customers will be extorted as a result of this incident, publicly or otherwise.”

Threat landscape for industrial automation systems in Q4 2025

15 April 2026 at 14:30

Statistics across all threats

The percentage of ICS computers on which malicious objects were blocked has been decreasing since the beginning of 2024. In Q4 2025, it was 19.7%. Over the past three years, the percentage has decreased by 1.36 times, and by 1.25 times since Q4 2023.

Percentage of ICS computers on which malicious objects were blocked, Q1 2023–Q4 2025

Regionally, in Q4 2025, the percentage of ICS computers on which malicious objects were blocked ranged from 8.5% in Northern Europe to 27.3% in Africa.

Regions ranked by percentage of ICS computers on which malicious objects were blocked

Regions ranked by percentage of ICS computers on which malicious objects were blocked

Four regions saw an increase in the percentage of ICS computers on which malicious objects were blocked. The most notable increases occurred in Southern Europe and South Asia. In Q3 2025, East Asia experienced a sharp increase triggered by the local spread of malicious scripts, but the figure has since returned to normal.

Feature of the quarter: worms in email

In Q4 2025, the percentage of ICS computers on which wormsinemailattachments were blocked increasedinallregions of the world.

Many of the blocked threats were related to the worm Backdoor.MSIL.XWorm. This malware is designed to persist on the system and then remotely control it.

Interestingly, this threat was not detected on ICS computers in the previous quarter, yet it appeared in all regions in Q4 2025.

A study found that the active spread of Backdoor.MSIL.XWorm via phishing emails was likely linked to the use by hackers of another malware obfuscation technique that was actively used during massive phishing campaigns in Q4 2025. These campaigns have been known since 2024 as “Curriculum-vitae-catalina”.

The attackers distributed phishing emails to HR managers, recruiters, and employees responsible for hiring. The messages were disguised as responses from job applicants with subjects such as “Resume” or “Attached Resume” and contained a malicious executable file under the guise of a curriculum vitae. Typically, the file was named Curriculum Vitae-Catalina.exe. When executed, it infected the system.

In Q4 2025, the threat spread across regions in two waves — one in October and another in November. Russia, Western Europe, South America, and North America (Canada) were attacked in October. A spike in Backdoor.MSIL.XWorm blocking was observed in other regions in November. The attack subsided in all regions in December.

The highest percentage of ICS computers on which Backdoor.MSIL.XWorm was blocked was observed in regions where threats from email clients had been historically blocked at high rates on ICS computers: Southern Europe, South America, and the Middle East.

At the same time, in Africa, where USB storage media are still actively used, the threat was also detected when removable devices were connected to ICS computers.

Selected industries

The biometrics sector has historically led the rankings of industries and OT infrastructures surveyed in this report in terms of the percentage of ICS computers on which malicious objects were blocked.

These systems are characterized by accessibility to and from the internet, as well as minimal cybersecurity controls by the consumer organization.

Rankings of industries and OT infrastructure by percentage of ICS computers on which malicious objects were blocked

In Q4 2025, the percentage of ICS computers on which malicious objects were blocked increased only in one sector: oil and gas. The corresponding figures increased in two regions: Russia, and Central Asia and the South Caucasus.

However, if we look at a broader time span, there is a downward trend in all the surveyed industries.

Diversity of detected malicious objects

In Q4 2025, Kaspersky protection solutions blocked malware from 10,142 different malware families of various categories on industrial automation systems.

In Q4 2025, there was an increase in the percentage of ICS computers on which worms, and miners in the form of executable files for Windows were blocked. These were the only categories that exhibited an increase.

Main threat sources

Depending on the threat detection and blocking scenario, it is not always possible to reliably identify the source. The circumstantial evidence for a specific source can be the blocked threat’s type (category).

The internet (visiting malicious or compromised internet resources; malicious content distributed via messengers; cloud data storage and processing services and CDNs), email clients (phishing emails), and removable storage devices remain the primary sources of threats to computers in an organization’s technology infrastructure.

In Q4 2025, the percentage of ICS computers on which malicious objects from various sources were blocked decreased. All sources except email clients saw their lowest levels in three years.

Percentage of ICS computers on which malicious objects from various sources were blocked

Percentage of ICS computers on which malicious objects from various sources were blocked

The same computer can be attacked by several categories of malware from the same source during a quarter. That computer is counted when calculating the percentage of attacked computers for each threat category, but is only counted once for the threat source (we count unique attacked computers). In addition, it is not always possible to accurately determine the initial infection attempt. Therefore, the total percentage of ICS computers on which various categories of threats from a certain source were blocked can exceed the percentage of computers affected by the source itself.

  • In Q4 2025, the percentage of ICS computers on which threats from the internet were blocked decreased to 7.67% and reached its lowest level since the beginning of 2023. The main categories of internet threats are malicious scripts and phishing pages, and denylisted internet resources. The percentage ranged from 3.96% in Northern Europe to 11.33% in South Asia.
  • The main categories of threats from email clients blocked on ICS computers were malicious scripts and phishing pages, spyware, and malicious documents. Most of the spyware detected in phishing emails was delivered as a password archive or a multi-layered script embedded in office document files. The percentage of ICS computers on which threats from email clients were blocked ranged from 0.64% in Northern Europe to 6.34% in Southern Europe.
  • The main categories of threats that were blocked when removable media was connected to ICS computers were worms, viruses, and spyware. The percentage of ICS computers on which threats from removable media were blocked ranged from 0.05% in Australia and New Zealand to 1.41% in Africa.
  • The main categories of threats that spread through network folders in Q4 2025 were viruses, AutoCAD malware, worms, and spyware. The percentage of ICS computers on which threats from network folders were blocked ranged from 0.01% in Northern Europe to 0.18% in East Asia.

Threat categories

Typical attacks blocked within an OT network are multi-step sequences of malicious activities, where each subsequent step of the attackers is aimed at increasing privileges and/or gaining access to other systems by exploiting the security problems of industrial enterprises, including OT infrastructures.

Malicious objects used for initial infection

In Q4 2025, the percentage of ICS computers on which denylisted internet resources were blocked decreased to 3.26%. This is the lowest quarterly figure since the beginning of 2022, and it has decreased by 1.8 times since Q2 2025.

Percentage of ICS computers on which denylisted internet resources were blocked, Q1 2023–Q4 2025

Percentage of ICS computers on which denylisted internet resources were blocked, Q1 2023–Q4 2025

Regionally, the percentage of ICS computers on which denylisted internet resources were blocked ranged from 1.74% in Northern Europe to 3.93% in Southeast Asia, which displaced Africa from first place. Russia rounded out the top three regions for this indicator.

The percentage of ICS computers on which malicious documents were blocked increased for three consecutive quarters. However, in Q4 2025 it decreased by 0.22 pp to 1.76%.

Percentage of ICS computers on which malicious documents were blocked, Q1 2023–Q4 2025

Percentage of ICS computers on which malicious documents were blocked, Q1 2023–Q4 2025

Regionally, the percentage ranged from 0.46% in Northern Europe to 3.82% in Southern Europe. In Q4 2025, the indicator increased in Eastern Europe, Russia, and Western Europe.

The percentage of ICS computers on which malicious scripts and phishing pages were blocked decreased to 6.58%. Despite the decline, this category led the rankings of threat categories in terms of the percentage of ICS computers on which they were blocked.

Percentage of ICS computers on which malicious scripts and phishing pages were blocked, Q1 2023–Q4 2025

Percentage of ICS computers on which malicious scripts and phishing pages were blocked, Q1 2023–Q4 2025

Regionally, the percentage ranged from 2.52% in Northern Europe to 10.50% in South Asia. The indicator increased in South Asia, South America, Southern Europe, and Africa. South Asia saw the most notable increase, at 3.47 pp.

Next-stage malware

Malicious objects used to initially infect computers deliver next-stage malware — spyware, ransomware, and miners — to victims’ computers. As a rule, the higher the percentage of ICS computers on which the initial infection malware is blocked, the higher the percentage for next-stage malware.

In Q4 2025, the percentage of ICS computers on which spyware, ransomware and web miners were blocked decreased. The rates were:

  • Spyware: 3.80% (down 0.24 pp). For the second quarter in a row, spyware took second place in the rankings of threat categories in terms of the percentage of ICS computers on which it was blocked.
  • Ransomware: 0.16% (down 0.01 pp).
  • Web miners: 0.24% (down 0.01 pp), this is the lowest level observed thus far in the period under review.

The percentage of ICS computers on which miners in the form of executable files for Windows were blocked increased to 0.60% (up 0.03 pp).

Self-propagating malware

Self-propagating malware (worms and viruses) is a category unto itself. Worms and virus-infected files were originally used for initial infection, but as botnet functionality evolved, they took on next-stage characteristics.

To spread across ICS networks, viruses and worms rely on removable media and network folders and are distributed in the form of infected files, such as archives with backups, office documents, pirated games and hacked applications. In rarer and more dangerous cases, web pages with network equipment settings, as well as files stored in internal document management systems, product lifecycle management (PLM) systems, resource management (ERP) systems and other web services are infected.

In Q4 2025, the percentage of ICS computers on which worms were blocked increased by 1.6 times to 1.60%. As mentioned above, this increase is related to a global phishing attack that spread the Backdoor.MSIL.XWorm backdoor worm across all regions of the world. The percentage increased in all regions. The biggest increase (up by 2.16 times) was in Southern Europe. The malware was primary distributed through email clients, and Southern Europe led the way in terms of the percentage of ICS computers on which threats from email clients were blocked.

The percentage of ICS computers on which viruses were blocked decreased to 1.33%.

AutoCAD malware

This category of malware can spread in a variety of ways, so it does not belong to a specific group.

After an increase in the previous quarter, the percentage of ICS computers on which AutoCAD malware was blocked decreased to 0.29% in Q4 2025.

Germany Doxes “UNKN,” Head of RU Ransomware Gangs REvil, GandCrab

6 April 2026 at 04:07

An elusive hacker who went by the handle “UNKN” and ran the early Russian ransomware groups GandCrab and REvil now has a name and a face. Authorities in Germany say 31-year-old Russian Daniil Maksimovich Shchukin headed both cybercrime gangs and helped carry out at least 130 acts of computer sabotage and extortion against victims across the country between 2019 and 2021.

Shchukin was named as UNKN (a.k.a. UNKNOWN) in an advisory published by the German Federal Criminal Police (the “Bundeskriminalamt” or BKA for short). The BKA said Shchukin and another Russian — 43-year-old Anatoly Sergeevitsch Kravchuk — extorted nearly $2 million euros across two dozen cyberattacks that caused more than 35 million euros in total economic damage.

Daniil Maksimovich SHCHUKIN, a.k.a. UNKN, and Anatoly Sergeevitsch Karvchuk, alleged leaders of the GandCrab and REvil ransomware groups.

Germany’s BKA said Shchukin acted as the head of one of the largest worldwide operating ransomware groups GandCrab and REvil, which pioneered the practice of double extortion — charging victims once for a key needed to unlock hacked systems, and a separate payment in exchange for a promise not to publish stolen data.

Shchukin’s name appeared in a Feb. 2023 filing (PDF) from the U.S. Justice Department seeking the seizure of various cryptocurrency accounts associated with proceeds from the REvil ransomware gang’s activities. The government said the digital wallet tied to Shchukin contained more than $317,000 in ill-gotten cryptocurrency.

The GandCrab ransomware affiliate program first surfaced in January 2018, and paid enterprising hackers huge shares of the profits just for hacking into user accounts at major corporations. The GandCrab team would then try to expand that access, often siphoning vast amounts of sensitive and internal documents in the process. The malware’s curators shipped five major revisions to the GandCrab code, each corresponding with sneaky new features and bug fixes aimed at thwarting the efforts of computer security firms to stymie the spread of the malware.

On May 31, 2019, the GandCrab team announced the group was shutting down after extorting more than $2 billion from victims. “We are a living proof that you can do evil and get off scot-free,” GandCrab’s farewell address famously quipped. “We have proved that one can make a lifetime of money in one year. We have proved that you can become number one by general admission, not in your own conceit.”

The REvil ransomware affiliate program materialized around the same as GandCrab’s demise, fronted by a user named UNKNOWN who announced on a Russian cybercrime forum that he’d deposited $1 million in the forum’s escrow to show he meant business. By this time, many cybersecurity experts had concluded REvil was little more than a reorganization of GandCrab.

UNKNOWN also gave an interview to Dmitry Smilyanets, a former malicious hacker hired by Recorded Future, wherein UNKNOWN described a rags-to-riches tale unencumbered by ethics and morals.

“As a child, I scrounged through the trash heaps and smoked cigarette butts,” UNKNOWN told Recorded Future. “I walked 10 km one way to the school. I wore the same clothes for six months. In my youth, in a communal apartment, I didn’t eat for two or even three days. Now I am a millionaire.”

As described in The Ransomware Hunting Team by Renee Dudley and Daniel Golden, UNKNOWN and REvil reinvested significant earnings into improving their success and mirroring practices of legitimate businesses. The authors wrote:

“Just as a real-world manufacturer might hire other companies to handle logistics or web design, ransomware developers increasingly outsourced tasks beyond their purview, focusing instead on improving the quality of their ransomware. The higher quality ransomware—which, in many cases, the Hunting Team could not break—resulted in more and higher pay-outs from victims. The monumental payments enabled gangs to reinvest in their enterprises. They hired more specialists, and their success accelerated.”

“Criminals raced to join the booming ransomware economy. Underworld ancillary service providers sprouted or pivoted from other criminal work to meet developers’ demand for customized support. Partnering with gangs like GandCrab, ‘cryptor’ providers ensured ransomware could not be detected by standard anti-malware scanners. ‘Initial access brokerages’ specialized in stealing credentials and finding vulnerabilities in target networks, selling that access to ransomware operators and affiliates. Bitcoin “tumblers” offered discounts to gangs that used them as a preferred vendor for laundering ransom payments. Some contractors were open to working with any gang, while others entered exclusive partnerships.”

REvil would evolve into a feared “big-game-hunting” machine capable of extracting hefty extortion payments from victims, largely going after organizations with more than $100 million in annual revenues and fat new cyber insurance policies that were known to pay out.

Over the July 4, 2021 weekend in the United States, REvil hacked into and extorted Kaseya, a company that handled IT operations for more than 1,500 businesses, nonprofits and government agencies. The FBI would later announce they’d infiltrated the ransomware group’s servers prior to the Kaseya hack but couldn’t tip their hand at the time. REvil never recovered from that core compromise, or from the FBI’s release of a free decryption key for REvil victims who couldn’t or didn’t pay.

Shchukin is from Krasnodar, Russia and is thought to reside there, the BKA said.

“Based on the investigations so far, it is assumed that the wanted person is abroad, presumably in Russia,” the BKA advised. “Travel behaviour cannot be ruled out.”

There is little that connects Shchukin to UNKNOWN’s various accounts on the Russian crime forums. But a review of the Russian crime forums indexed by the cyber intelligence firm Intel 471 shows there is plenty connecting Shchukin to a hacker identity called “Ger0in” who operated large botnets and sold “installs” — allowing other cybercriminals to rapidly deploy malware of their choice to thousands of PCs in one go. However, Ger0in was only active between 2010 and 2011, well before UNKNOWN’s appearance as the REvil front man.

A review of the mugshots released by the BKA at the image comparison site Pimeyes found a match on this birthday celebration from 2023, which features a young man named Daniel wearing the same fancy watch as in the BKA photos.

Update, April 6, 12:06 p.m. ET: A reader forwarded this English-dubbed audio recording from a ccc.de (37C3) conference talk in Germany from 2023 that previously outed Shchukin as the REvil leader (Shchuckin is mentioned at around 24:25).

‘CanisterWorm’ Springs Wiper Attack Targeting Iran

23 March 2026 at 16:43

A financially motivated data theft and extortion group is attempting to inject itself into the Iran war, unleashing a worm that spreads through poorly secured cloud services and wipes data on infected systems that use Iran’s time zone or have Farsi set as the default language.

Experts say the wiper campaign against Iran materialized this past weekend and came from a relatively new cybercrime group known as TeamPCP. In December 2025, the group began compromising corporate cloud environments using a self-propagating worm that went after exposed Docker APIs, Kubernetes clusters, Redis servers, and the React2Shell vulnerability. TeamPCP then attempted to move laterally through victim networks, siphoning authentication credentials and extorting victims over Telegram.

A snippet of the malicious CanisterWorm that seeks out and destroys data on systems that match Iran’s timezone or have Farsi as the default language. Image: Aikido.dev.

In a profile of TeamPCP published in January, the security firm Flare said the group weaponizes exposed control planes rather than exploiting endpoints, predominantly targeting cloud infrastructure over end-user devices, with Azure (61%) and AWS (36%) accounting for 97% of compromised servers.

“TeamPCP’s strength does not come from novel exploits or original malware, but from the large-scale automation and integration of well-known attack techniques,” Flare’s Assaf Morag wrote. “The group industrializes existing vulnerabilities, misconfigurations, and recycled tooling into a cloud-native exploitation platform that turns exposed infrastructure into a self-propagating criminal ecosystem.”

On March 19, TeamPCP executed a supply chain attack against the vulnerability scanner Trivy from Aqua Security, injecting credential-stealing malware into official releases on GitHub actions. Aqua Security said it has since removed the harmful files, but the security firm Wiz notes the attackers were able to publish malicious versions that snarfed SSH keys, cloud credentials, Kubernetes tokens and cryptocurrency wallets from users.

Over the weekend, the same technical infrastructure TeamPCP used in the Trivy attack was leveraged to deploy a new malicious payload which executes a wiper attack if the user’s timezone and locale are determined to correspond to Iran, said Charlie Eriksen, a security researcher at Aikido. In a blog post published on Sunday, Eriksen said if the wiper component detects that the victim is in Iran and has access to a Kubernetes cluster, it will destroy data on every node in that cluster.

“If it doesn’t it will just wipe the local machine,” Eriksen told KrebsOnSecurity.

Image: Aikido.dev.

Aikido refers to TeamPCP’s infrastructure as “CanisterWorm” because the group orchestrates their campaigns using an Internet Computer Protocol (ICP) canister — a system of tamperproof, blockchain-based “smart contracts” that combine both code and data. ICP canisters can serve Web content directly to visitors, and their distributed architecture makes them resistant to takedown attempts. These canisters will remain reachable so long as their operators continue to pay virtual currency fees to keep them online.

Eriksen said the people behind TeamPCP are bragging about their exploits in a group on Telegram and claim to have used the worm to steal vast amounts of sensitive data from major companies, including a large multinational pharmaceutical firm.

“When they compromised Aqua a second time, they took a lot of GitHub accounts and started spamming these with junk messages,” Eriksen said. “It was almost like they were just showing off how much access they had. Clearly, they have an entire stash of these credentials, and what we’ve seen so far is probably a small sample of what they have.”

Security experts say the spammed GitHub messages could be a way for TeamPCP to ensure that any code packages tainted with their malware will remain prominent in GitHub searches. In a newsletter published today titled GitHub is Starting to Have a Real Malware Problem, Risky Business reporter Catalin Cimpanu writes that attackers often are seen pushing meaningless commits to their repos or using online services that sell GitHub stars and “likes” to keep malicious packages at the top of the GitHub search page.

This weekend’s outbreak is the second major supply chain attack involving Trivy in as many months. At the end of February, Trivy was hit as part of an automated threat called HackerBot-Claw, which mass exploited misconfigured workflows in GitHub Actions to steal authentication tokens.

Eriksen said it appears TeamPCP used access gained in the first attack on Aqua Security to perpetrate this weekend’s mischief. But he said there is no reliable way to tell whether TeamPCP’s wiper actually succeeded in trashing any data from victim systems, and that the malicious payload was only active for a short time over the weekend.

“They’ve been taking [the malicious code] up and down, rapidly changing it adding new features,” Eriksen said, noting that when the malicious canister wasn’t serving up malware downloads it was pointing visitors to a Rick Roll video on YouTube.

“It’s a little all over the place, and there’s a chance this whole Iran thing is just their way of getting attention,” Eriksen said. “I feel like these people are really playing this Chaotic Evil role here.”

Cimpanu observed that supply chain attacks have increased in frequency of late as threat actors begin to grasp just how efficient they can be, and his post documents an alarming number of these incidents since 2024.

“While security firms appear to be doing a good job spotting this, we’re also gonna need GitHub’s security team to step up,” Cimpanu wrote. “Unfortunately, on a platform designed to copy (fork) a project and create new versions of it (clones), spotting malicious additions to clones of legitimate repos might be quite the engineering problem to fix.”

Update, 2:40 p.m. ET: Wiz is reporting that TeamPCP also pushed credential stealing malware to the KICS vulnerability scanner from Checkmarx, and that the scanner’s GitHub Action was compromised between 12:58 and 16:50 UTC today (March 23rd).

Please Don’t Feed the Scattered Lapsus ShinyHunters

2 February 2026 at 17:15

A prolific data ransom gang that calls itself Scattered Lapsus ShinyHunters (SLSH) has a distinctive playbook when it seeks to extort payment from victim firms: Harassing, threatening and even swatting executives and their families, all while notifying journalists and regulators about the extent of the intrusion. Some victims reportedly are paying — perhaps as much to contain the stolen data as to stop the escalating personal attacks. But a top SLSH expert warns that engaging at all beyond a “We’re not paying” response only encourages further harassment, noting that the group’s fractious and unreliable history means the only winning move is not to pay.

Unlike traditional, highly regimented Russia-based ransomware affiliate groups, SLSH is an unruly and somewhat fluid English-language extortion gang that appears uninterested in building a reputation of consistent behavior whereby victims might have some measure of confidence that the criminals will keep their word if paid.

That’s according to Allison Nixon, director of research at the New York City based security consultancy Unit 221B. Nixon has been closely tracking the criminal group and individual members as they bounce between various Telegram channels used to extort and harass victims, and she said SLSH differs from traditional data ransom groups in other important ways that argue against trusting them to do anything they say they’ll do — such as destroying stolen data.

Like SLSH, many traditional Russian ransomware groups have employed high-pressure tactics to force payment in exchange for a decryption key and/or a promise to delete stolen data, such as publishing a dark web shaming blog with samples of stolen data next to a countdown clock, or notifying journalists and board members of the victim company. But Nixon said the extortion from SLSH quickly escalates way beyond that — to threats of physical violence against executives and their families, DDoS attacks on the victim’s website, and repeated email-flooding campaigns.

SLSH is known for breaking into companies by phishing employees over the phone, and using the purloined access to steal sensitive internal data. In a January 30 blog post, Google’s security forensics firm Mandiant said SLSH’s most recent extortion attacks stem from incidents spanning early to mid-January 2026, when SLSH members pretended to be IT staff and called employees at targeted victim organizations claiming that the company was updating MFA settings.

“The threat actor directed the employees to victim-branded credential harvesting sites to capture their SSO credentials and MFA codes, and then registered their own device for MFA,” the blog post explained.

Victims often first learn of the breach when their brand name is uttered on whatever ephemeral new public Telegram group chat SLSH is using to threaten, extort and harass their prey. According to Nixon, the coordinated harassment on the SLSH Telegram channels is part of a well-orchestrated strategy to overwhelm the victim organization by manufacturing humiliation that pushes them over the threshold to pay.

Nixon said multiple executives at targeted organizations have been subject to “swatting” attacks, wherein SLSH communicated a phony bomb threat or hostage situation at the target’s address in the hopes of eliciting a heavily armed police response at their home or place of work.

“A big part of what they’re doing to victims is the psychological aspect of it, like harassing executives’ kids and threatening the board of the company,” Nixon told KrebsOnSecurity. “And while these victims are getting extortion demands, they’re simultaneously getting outreach from media outlets saying, ‘Hey, do you have any comments on the bad things we’re going to write about you.”

In a blog post today, Unit 221B argues that no one should negotiate with SLSH because the group has demonstrated a willingness to extort victims based on promises that it has no intention to keep. Nixon points out that all of SLSH’s known members hail from The Com, shorthand for a constellation of cybercrime-focused Discord and Telegram communities which serve as a kind of distributed social network that facilitates instant collaboration.

Nixon said Com-based extortion groups tend to instigate feuds and drama between group members, leading to lying, betrayals, credibility destroying behavior, backstabbing, and sabotaging each other.

“With this type of ongoing dysfunction, often compounding by substance abuse, these threat actors often aren’t able to act with the core goal in mind of completing a successful, strategic ransom operation,” Nixon wrote. “They continually lose control with outbursts that put their strategy and operational security at risk, which severely limits their ability to build a professional, scalable, and sophisticated criminal organization network for continued successful ransoms – unlike other, more tenured and professional criminal organizations focused on ransomware alone.”

Intrusions from established ransomware groups typically center around encryption/decryption malware that mostly stays on the affected machine. In contrast, Nixon said, ransom from a Com group is often structured the same as violent sextortion schemes against minors, wherein members of The Com will steal damaging information, threaten to release it, and “promise” to delete it if the victim complies without any guarantee or technical proof point that they will keep their word. She writes:

A key component of SLSH’s efforts to convince victims to pay, Nixon said, involves manipulating the media into hyping the threat posed by this group. This approach also borrows a page from the playbook of sextortion attacks, she said, which encourages predators to keep targets continuously engaged and worrying about the consequences of non-compliance.

“On days where SLSH had no substantial criminal ‘win’ to announce, they focused on announcing death threats and harassment to keep law enforcement, journalists, and cybercrime industry professionals focused on this group,” she said.

Nixon knows a thing or two about being threatened by SLSH: For the past several months, the group’s Telegram channels have been replete with threats of physical violence against her, against Yours Truly, and against other security researchers. These threats, she said, are just another way the group seeks to generate media attention and achieve a veneer of credibility, but they are useful as indicators of compromise because SLSH members tend to name drop and malign security researchers even in their communications with victims.

“Watch for the following behaviors in their communications to you or their public statements,” Unit 221B’s advisory reads. “Repeated abusive mentions of Allison Nixon (or “A.N”), Unit 221B, or cybersecurity journalists—especially Brian Krebs—or any other cybersecurity employee, or cybersecurity company. Any threats to kill, or commit terrorism, or violence against internal employees, cybersecurity employees, investigators, and journalists.”

Unit 221B says that while the pressure campaign during an extortion attempt may be traumatizing to employees, executives, and their family members, entering into drawn-out negotiations with SLSH incentivizes the group to increase the level of harm and risk, which could include the physical safety of employees and their families.

“The breached data will never go back to the way it was, but we can assure you that the harassment will end,” Nixon said. “So, your decision to pay should be a separate issue from the harassment. We believe that when you separate these issues, you will objectively see that the best course of action to protect your interests, in both the short and long term, is to refuse payment.”

Threat landscape for industrial automation systems in Q3 2025

25 December 2025 at 11:00

Statistics across all threats

In Q3 2025, the percentage of ICS computers on which malicious objects were blocked decreased from the previous quarter by 0.4 pp to 20.1%. This is the lowest level for the observed period.

Percentage of ICS computers on which malicious objects were blocked, Q3 2022–Q3 2025

Percentage of ICS computers on which malicious objects were blocked, Q3 2022–Q3 2025

Regionally, the percentage of ICS computers on which malicious objects were blocked ranged from 9.2% in Northern Europe to 27.4% in Africa.

Percentage of ICS computers on which the activity of malicious objects of various categories was blocked

In Q3 2025, there was a decrease in the percentage of ICS computers on which denylisted internet resources and miners of both categories were blocked. These were the only categories that exhibited a decrease.

Main threat sources

Depending on the threat detection and blocking scenario, it is not always possible to reliably identify the source. The circumstantial evidence for a specific source can be the blocked threat’s type (category).

The internet (visiting malicious or compromised internet resources; malicious content distributed via messengers; cloud data storage and processing services and CDNs), email clients (phishing emails), and removable storage devices remain the primary sources of threats to computers in an organization’s technology infrastructure.

In Q3 2025, the percentage of ICS computers on which malicious objects from various sources were blocked decreased.

Percentage of ICS computers on which malicious objects from various sources were blocked

The same computer can be attacked by several categories of malware from the same source during a quarter. That computer is counted when calculating the percentage of attacked computers for each threat category, but is only counted once for the threat source (we count unique attacked computers). In addition, it is not always possible to accurately determine the initial infection attempt. Therefore, the total percentage of ICS computers on which various categories of threats from a certain source were blocked can exceed the percentage of threats from the source itself.

  • The main categories of threats from the internet blocked on ICS computers in Q3 2025 were malicious scripts and phishing pages, and denylisted internet resources. The percentage ranged from 4.57% in Northern Europe to 10.31% in Africa.
  • The main categories of threats from email clients blocked on ICS computers were malicious scripts and phishing pages, spyware, and malicious documents. Most of the spyware detected in phishing emails was delivered as a password-protected archive or a multi-layered script embedded in an office document. The percentage of ICS computers on which threats from email clients were blocked ranged from 0.78% in Russia to 6.85% in Southern Europe.
  • The main categories of threats that were blocked when removable media was connected to ICS computers were worms, viruses, and spyware. The percentage of ICS computers on which threats from this source were blocked ranged from 0.05% in Australia and New Zealand to 1.43% in Africa.
  • The main categories of threats that spread through network folders were viruses, AutoCAD malware, worms, and spyware. The percentages of ICS computers where threats from this source were blocked ranged from 0.006% in Northern Europe to 0.20% in East Asia.

Threat categories

Typical attacks blocked within an OT network are multi-step sequences of malicious activities, where each subsequent step of the attackers is aimed at increasing privileges and/or gaining access to other systems by exploiting the security problems of industrial enterprises, including technological infrastructures.

Malicious objects used for initial infection

In Q3 2025, the percentage of ICS computers on which denylisted internet resources were blocked decreased to 4.01%. This is the lowest quarterly figure since the beginning of 2022.

Percentage of ICS computers on which denylisted internet resources were blocked, Q3 2022–Q3 2025

Percentage of ICS computers on which denylisted internet resources were blocked, Q3 2022–Q3 2025

Regionally, the percentage of ICS computers on which denylisted internet resources were blocked ranged from 2.35% in Australia and New Zealand to 4.96% in Africa. Southeast Asia and South Asia were also among the top three regions for this indicator.

The percentage of ICS computers on which malicious documents were blocked has grown for three consecutive quarters, following a decline at the end of 2024. In Q3 2025, it reached 1,98%.

Percentage of ICS computers on which malicious documents were blocked, Q3 2022–Q3 2025

Percentage of ICS computers on which malicious documents were blocked, Q3 2022–Q3 2025

The indicator increased in four regions: South America, East Asia, Southeast Asia, and Australia and New Zealand. South America saw the largest increase as a result of a large-scale phishing campaign in which attackers used new exploits for an old vulnerability (CVE-2017-11882) in Microsoft Office Equation Editor to deliver various spyware to victims’ computers. It is noteworthy that the attackers in this phishing campaign used localized Spanish-language emails disguised as business correspondence.

In Q3 2025, the percentage of ICS computers on which malicious scripts and phishing pages were blocked increased to 6.79%. This category led the rankings of threat categories in terms of the percentage of ICS computers on which they were blocked.

Percentage of ICS computers on which malicious scripts and phishing pages were blocked, Q3 2022–Q3 2025

Percentage of ICS computers on which malicious scripts and phishing pages were blocked, Q3 2022–Q3 2025

Regionally, the percentage of ICS computers on which malicious scripts and phishing pages were blocked ranged from 2.57% in Northern Europe to 9.41% in Africa. The top three regions for this indicator were Africa, East Asia, and South America. The indicator increased the most in East Asia (by a dramatic 5.23 pp) as a result of the local spread of malicious spyware scripts loaded into the memory of popular torrent clients including MediaGet.

Next-stage malware

Malicious objects used to initially infect computers deliver next-stage malware — spyware, ransomware, and miners — to victims’ computers. As a rule, the higher the percentage of ICS computers on which the initial infection malware is blocked, the higher the percentage for next-stage malware.
In Q3 2025, the percentage of ICS computers on which spyware and ransomware were blocked increased. The rates were:

  • spyware: 4.04% (up 0.20 pp);
  • ransomware: 0.17% (up 0.03 pp).

The percentage of ICS computers on which miners of both categories were blocked decreased. The rates were:

  • miners in the form of executable files for Windows: 0.57% (down 0.06 pp), it’s the lowest level since Q3 2022;
  • web miners: 0.25% (down 0.05 pp). This is the lowest level since Q3 2022.

Self-propagating malware

Self-propagating malware (worms and viruses) is a category unto itself. Worms and virus-infected files were originally used for initial infection, but as botnet functionality evolved, they took on next-stage characteristics.

To spread across ICS networks, viruses and worms rely on removable media and network folders in the form of infected files, such as archives with backups, office documents, pirated games and hacked applications. In rarer and more dangerous cases, web pages with network equipment settings, as well as files stored in internal document management systems, product lifecycle management (PLM) systems, resource management (ERP) systems and other web services are infected.

In Q3 2025, the percentage of ICS computers on which worms and viruses were blocked increased to 1.26% (by 0.04 pp) and 1.40% (by 0.11 pp), respectively.

AutoCAD malware

This category of malware can spread in a variety of ways, so it does not belong to a specific group.

In Q3 2025, the percentage of ICS computers on which AutoCAD malware was blocked slightly increased to 0.30% (by 0.01 pp).

Meet Rey, the Admin of ‘Scattered Lapsus$ Hunters’

26 November 2025 at 18:22

A prolific cybercriminal group that calls itself “Scattered LAPSUS$ Hunters” has dominated headlines this year by regularly stealing data from and publicly mass extorting dozens of major corporations. But the tables seem to have turned somewhat for “Rey,” the moniker chosen by the technical operator and public face of the hacker group: Earlier this week, Rey confirmed his real life identity and agreed to an interview after KrebsOnSecurity tracked him down and contacted his father.

Scattered LAPSUS$ Hunters (SLSH) is thought to be an amalgamation of three hacking groups — Scattered Spider, LAPSUS$ and ShinyHunters. Members of these gangs hail from many of the same chat channels on the Com, a mostly English-language cybercriminal community that operates across an ocean of Telegram and Discord servers.

In May 2025, SLSH members launched a social engineering campaign that used voice phishing to trick targets into connecting a malicious app to their organization’s Salesforce portal. The group later launched a data leak portal that threatened to publish the internal data of three dozen companies that allegedly had Salesforce data stolen, including ToyotaFedExDisney/Hulu, and UPS.

The new extortion website tied to ShinyHunters, which threatens to publish stolen data unless Salesforce or individual victim companies agree to pay a ransom.

Last week, the SLSH Telegram channel featured an offer to recruit and reward “insiders,” employees at large companies who agree to share internal access to their employer’s network for a share of whatever ransom payment is ultimately paid by the victim company.

SLSH has solicited insider access previously, but their latest call for disgruntled employees started making the rounds on social media at the same time news broke that the cybersecurity firm Crowdstrike had fired an employee for allegedly sharing screenshots of internal systems with the hacker group (Crowdstrike said their systems were never compromised and that it has turned the matter over to law enforcement agencies).

The Telegram server for the Scattered LAPSUS$ Hunters has been attempting to recruit insiders at large companies.

Members of SLSH have traditionally used other ransomware gangs’ encryptors in attacks, including malware from ransomware affiliate programs like ALPHV/BlackCat, Qilin, RansomHub, and DragonForce. But last week, SLSH announced on its Telegram channel the release of their own ransomware-as-a-service operation called ShinySp1d3r.

The individual responsible for releasing the ShinySp1d3r ransomware offering is a core SLSH member who goes by the handle “Rey” and who is currently one of just three administrators of the SLSH Telegram channel. Previously, Rey was an administrator of the data leak website for Hellcat, a ransomware group that surfaced in late 2024 and was involved in attacks on companies including Schneider Electric, Telefonica, and Orange Romania.

A recent, slightly redacted screenshot of the Scattered LAPSUS$ Hunters Telegram channel description, showing Rey as one of three administrators.

Also in 2024, Rey would take over as administrator of the most recent incarnation of BreachForums, an English-language cybercrime forum whose domain names have been seized on multiple occasions by the FBI and/or by international authorities. In April 2025, Rey posted on Twitter/X about another FBI seizure of BreachForums.

On October 5, 2025, the FBI announced it had once again seized the domains associated with BreachForums, which it described as a major criminal marketplace used by ShinyHunters and others to traffic in stolen data and facilitate extortion.

“This takedown removes access to a key hub used by these actors to monetize intrusions, recruit collaborators, and target victims across multiple sectors,” the FBI said.

Incredibly, Rey would make a series of critical operational security mistakes last year that provided multiple avenues to ascertain and confirm his real-life identity and location. Read on to learn how it all unraveled for Rey.

WHO IS REY?

According to the cyber intelligence firm Intel 471, Rey was an active user on various BreachForums reincarnations over the past two years, authoring more than 200 posts between February 2024 and July 2025. Intel 471 says Rey previously used the handle “Hikki-Chan” on BreachForums, where their first post shared data allegedly stolen from the U.S. Centers for Disease Control and Prevention (CDC).

In that February 2024 post about the CDC, Hikki-Chan says they could be reached at the Telegram username @wristmug. In May 2024, @wristmug posted in a Telegram group chat called “Pantifan” a copy of an extortion email they said they received that included their email address and password.

The message that @wristmug cut and pasted appears to have been part of an automated email scam that claims it was sent by a hacker who has compromised your computer and used your webcam to record a video of you while you were watching porn. These missives threaten to release the video to all your contacts unless you pay a Bitcoin ransom, and they typically reference a real password the recipient has used previously.

“Noooooo,” the @wristmug account wrote in mock horror after posting a screenshot of the scam message. “I must be done guys.”

A message posted to Telegram by Rey/@wristmug.

In posting their screenshot, @wristmug redacted the username portion of the email address referenced in the body of the scam message. However, they did not redact their previously-used password, and they left the domain portion of their email address (@proton.me) visible in the screenshot.

O5TDEV

Searching on @wristmug’s rather unique 15-character password in the breach tracking service Spycloud finds it is known to have been used by just one email address: cybero5tdev@proton.me. According to Spycloud, those credentials were exposed at least twice in early 2024 when this user’s device was infected with an infostealer trojan that siphoned all of its stored usernames, passwords and authentication cookies (a finding that was initially revealed in March 2025 by the cyber intelligence firm KELA).

Intel 471 shows the email address cybero5tdev@proton.me belonged to a BreachForums member who went by the username o5tdev. Searching on this nickname in Google brings up at least two website defacement archives showing that a user named o5tdev was previously involved in defacing sites with pro-Palestinian messages. The screenshot below, for example, shows that 05tdev was part of a group called Cyb3r Drag0nz Team.

Rey/o5tdev’s defacement pages. Image: archive.org.

A 2023 report from SentinelOne described Cyb3r Drag0nz Team as a hacktivist group with a history of launching DDoS attacks and cyber defacements as well as engaging in data leak activity.

“Cyb3r Drag0nz Team claims to have leaked data on over a million of Israeli citizens spread across multiple leaks,” SentinelOne reported. “To date, the group has released multiple .RAR archives of purported personal information on citizens across Israel.”

The cyber intelligence firm Flashpoint finds the Telegram user @05tdev was active in 2023 and early 2024, posting in Arabic on anti-Israel channels like “Ghost of Palestine” [full disclosure: Flashpoint is currently an advertiser on this blog].

‘I’M A GINTY’

Flashpoint shows that Rey’s Telegram account (ID7047194296) was particularly active in a cybercrime-focused channel called Jacuzzi, where this user shared several personal details, including that their father was an airline pilot. Rey claimed in 2024 to be 15 years old, and to have family connections to Ireland.

Specifically, Rey mentioned in several Telegram chats that he had Irish heritage, even posting a graphic that shows the prevalence of the surname “Ginty.”

Spycloud indexed hundreds of credentials stolen from cybero5dev@proton.me, and those details indicate that Rey’s computer is a shared Microsoft Windows device located in Amman, Jordan. The credential data stolen from Rey in early 2024 show there are multiple users of the infected PC, but that all shared the same last name of Khader and an address in Amman, Jordan.

The “autofill” data lifted from Rey’s family PC contains an entry for a 46-year-old Zaid Khader that says his mother’s maiden name was Ginty. The infostealer data also shows Zaid Khader frequently accessed internal websites for employees of Royal Jordanian Airlines.

MEET SAIF

The infostealer data makes clear that Rey’s full name is Saif Al-Din Khader. Having no luck contacting Saif directly, KrebsOnSecurity sent an email to his father Zaid. The message invited the father to respond via email, phone or Signal, explaining that his son appeared to be deeply enmeshed in a serious cybercrime conspiracy.

Less than two hours later, I received a Signal message from Saif, who said his dad suspected the email was a scam and had forwarded it to him.

“I saw your email, unfortunately I don’t think my dad would respond to this because they think its some ‘scam email,'” said Saif, who told me he turns 16 years old next month. “So I decided to talk to you directly.”

Saif explained that he’d already heard from European law enforcement officials, and had been trying to extricate himself from SLSH. When asked why then he was involved in releasing SLSH’s new ShinySp1d3r ransomware-as-a-service offering, Saif said he couldn’t just suddenly quit the group.

“Well I cant just dip like that, I’m trying to clean up everything I’m associated with and move on,” he said.

He also shared that ShinySp1d3r is just a rehash of Hellcat ransomware, except modified with AI tools. “I gave the source code of Hellcat ransomware out basically.”

Saif claims he reached out on his own recently to the Telegram account for Operation Endgame, the codename for an ongoing law enforcement operation targeting cybercrime services, vendors and their customers.

“I’m already cooperating with law enforcement,” Saif said. “In fact, I have been talking to them since at least June. I have told them nearly everything. I haven’t really done anything like breaching into a corp or extortion related since September.”

Saif suggested that a story about him right now could endanger any further cooperation he may be able to provide. He also said he wasn’t sure if the U.S. or European authorities had been in contact with the Jordanian government about his involvement with the hacking group.

“A story would bring so much unwanted heat and would make things very difficult if I’m going to cooperate,” Saif said. “I’m unsure whats going to happen they said they’re in contact with multiple countries regarding my request but its been like an entire week and I got no updates from them.”

Saif shared a screenshot that indicated he’d contacted Europol authorities late last month. But he couldn’t name any law enforcement officials he said were responding to his inquiries, and KrebsOnSecurity was unable to verify his claims.

“I don’t really care I just want to move on from all this stuff even if its going to be prison time or whatever they gonna say,” Saif said.

Tips to make your summer travels cyber safe

17 June 2025 at 15:51

Ready, set, pack! Summer travel season is here and that means family road trips, beach vacations, international adventures and more. While summertime is prime time for getaways, did you know it’s also prime time for online fraud? Scammers are targeting the travel industry, putting millions of travelers at increased risk. Research shows that the travel and tourism sector ranked third in cyberattacks, with nearly 31% of hospitality organizations experiencing a data breach and a record 340 million people affected by cybercrimes. According to Mastercard, travel-related fraud in 2024 increased by 18% during the summer peak season and 28% in the winter peak season. 

Why travelers are prime targets

Being in an unfamiliar environment can put your personal information at risk if you’re relying on public Wi-Fi networks, using shared devices, and carrying valuable personal and business data on mobile devices. Let’s be honest, when you go into “vacation mode” and start relaxing, it’s only natural that you might also start letting your guard down. Even the best trips can have stressful moments, and when you miss a flight or get lost in a new destination, it’s easy to become less vigilant about protecting your cybersecurity. This is especially true when you travel to foreign countries. In fact, 90% of international travelers admit to risky tech practices while abroad. Fewer than 1 in 3 travelers (31%) protect their data with a virtual private network (VPN) when traveling internationally.

What to know before you go

Believe it or not, the risks to your data security start long before your vacation begins. As soon as you start booking your trip, the cybercriminals start circling. Fraud rates in sectors associated with the early stages of trip planning increased more than 12% between 2023 and 2024. At a time when inflation and economic pressures are on the rise, people are looking for deep discounts, and scammers are seizing the opportunity to steal your private data and your money.

  • Fake travel websites and rental listings: When you find a killer price on a luxury cruise, a European tour or an oceanfront Airbnb, take another look before you book! Scammers use phony offers, manipulated destination photos, and fake confirmation links to lure victims into “purchasing” great travel deals. Always double check and confirm you’re dealing with a legitimate website or listing before you hand over any credit card information.
  • Phishing scams: Phishing scams that target travel-related platforms are on the rise. Cybercriminals pose as legitimate organizations and use fake emails, text messages and phone calls to lure you into giving up financial information. These messages often ask you to click on links that embed malicious software onto your device and steal your sensitive data. In 2024, the travel website booking.com reported a 500%-900% increase in travel-related phishing scams. This rise was attributed to the large number of scams using AI, making it easier for criminals to mimic trusted sources. If you get a suspicious message, call the company or go to their website and log in directly before clicking on any links.
  • Loyalty fraud: Loyalty fraud, also known as points fraud, happens when scammers steal points or personal information from a loyalty program. The travel industry is especially vulnerable to this type of attack because so many travel-related companies, including travel agents, cruise lines, airlines and hotels, offer points programs for frequent travelers. Thieves often access loyalty accounts with credentials stolen in a data breach. Be sure to create strong passwords for your accounts and check your balances regularly.

Pre-trip security

Before you hit the road, help protect your digital data and devices with a few simple security practices.

  • Alert your financial institutions: Only about half of travelers (52%) alert their financial institutions before traveling abroad, but it’s a powerful way to fight cybercrime. When banks and credit card companies know your travel plans, it’s much easier for them to flag any suspicious transactions.
  • Turn off your Bluetooth:  Bluetooth technology automatically creates wireless connections and can give cybercriminals the ability to see what apps and websites you’re logged into. Only 44% of travelers say they make sure to turn off their Bluetooth signal, but it’s a simple way to thwart hackers. It’s also a good idea to turn off device sharing features and update your passwords before a trip.
  • Update your Wi-Fi setting: Joining unknown Wi-Fi networks is very risky and can open up your personal data to hackers. Since public Wi-Fi often has weak security,  it’s important that your phone doesn’t connect to unsecured networks automatically. Make sure to go into your phone settings and disable auto-join for unknown Wi-Fi networks. It’s a simple way to add a layer of protection when you travel.
  • Use “Find My Device” features: Enable the tracking features on your devices that can locate them if they’re lost or stolen – Find My device for iOS and Find Hub for Android.

Cybersecurity travel risks

  • Rental cars: Did you know that the simple act of syncing your phone to your rental car’s infotainment system can expose your sensitive information to cybercrime? Your phone contains all kinds of information that hackers can use, including contacts, text messages, passwords and more. Infotainment systems store your information each time you connect, and it stays there unless you manually delete it. Security experts say while 57% of people sync their phones to rental cars, only half of them take steps to remove their information. Always remember to delete your profile and data from your rental car before returning it!
  • Screen snoopers: Be cautious of screen snoopers (aka shoulder surfers) who try to see the activity on your laptop or phone in public places like planes, airports, and restaurants. To prevent hackers from stealing your passwords and other private information, use privacy screen protectors to shield your screens from prying eyes and always stay aware of your surroundings.
  • Airport and hotel Wi-Fi:  Always be wary of public Wi-Fi networks when you’re on the road. They’re often unprotected and can make it easy for cybercriminals to intercept your data. Poor Wi-Fi security at airports and hotels can allow hackers to swipe your credentials, lock you out of accounts, and even demand a ransom for your stolen data. To ensure safety while online on public WIFI, purchase a VPN for your devices, like Webroot’s Secure VPN.
  • Fake hotspot attacks: Fraudsters often set up fake hotspots to steal your information. Sometimes they alter the name of a genuine hotspot slightly (Starbucks-Coffee instead of StarbucksCoffee) to trick you into connecting. Always double-check the full network name before logging on to a public hotspot. Also, check to see if the site is using encryption. Legitimate sites that begin with “https” protect your information and make it unreadable to hackers.
  • Charging stations: Public charging stations are super convenient when you’re running low on battery, but they can also pose security risks. Cybercriminals can install malicious software on these stations to steal your device’s data, a tactic known as juice jacking. Always avoid plugging directly into public charging stations and play it safe by packing your own wall chargers, car chargers and external batteries when you travel.
  • Business centers and airport Lounges: Business Centers and lounges typically provide desktop computers for simple tasks like checking emails or printing boarding passes. While convenient, these public computers may be risky, as attackers can plant malware or install hardware that records your keystrokes. When traveling, use your personal devices whenever possible.

Travel safety best practices

  • Use Wi-Fi networks safely: Always connect using the public Wi-Fi setting, and do not enable auto-reconnect. Always confirm an HTTPS connection when browsing the internet. Avoid accessing websites that require you to supply personal data, such as social security numbers.
  • Avoid financial sites: Refrain from checking your personal banking apps or financial information over public Wi-Fi.
  • Use VPN protection: A VPN encrypts your internet connection, providing a secure channel for your data. Webroot Secure VPN gives you security and peace of mind by protecting your personal information when you’re on public Wi-Fi.
  • Enable two-factor authentication: Use Two-factor Authentication (TFA) on your gadgets and electronic devices. Adding an extra layer of security to your accounts can prevent unauthorized access.
  • Limit public posts about your location: Avoid sharing specific details about your location and travel plans on social media to prevent potential targeting by scammers.
  • Check mobile device settings: Adjust the screen settings on your devices to allow for a shorter automatic sleep feature. Implement screen locks, biometric security, and privacy settings for location services.

Build strong digital defenses for your entire family

28 May 2025 at 20:37

The month of June is a time for fun in the sun and a break from the school year, but did you know it’s also the perfect time to step up your family’s online security? June is Internet Safety Month, a yearly reminder to strengthen your defenses against online threats. In today’s hyper-connected world, we use the internet for just about everything, from shopping to banking to streaming and work. That goes for your kids as well. Many of their favorite activities, including gaming and connecting with friends on social media, are connected to the internet.  While all this access means added convenience, it also means constant threats to your family’s online safety.

From phishing scams to malware, hackers are constantly looking for ways to exploit weaknesses in cybersecurity systems and software. Their goal is always the same: to get access to personal data and use it for profit. The rising numbers tell the story. In 2024, the FBI’s Internet Crime Complaint Center (IC3) received more than 850,000 cybercrime complaints, with reported losses exceeding $10.3 billion. This is partly due to the increase in data breaches. Studies show that 51% of Americans report they’ve been victims of a data breach, and 64% say they’ve changed their online behavior for fear of escalating online threats like ransomware and identity theft.

Keep summer screen time safe

It’s not just adults getting targeted online. Children and teens are increasingly exposed to scams (even extortion scams), cyberbullying, and inappropriate content—especially during summer when screen time surges. A recent Pew Research study found that 45% of teens are online almost constantly. So how do you let your kids enjoy their screens safely? Webroot Total Protection and Webroot Essentials offer parental controls that make it easy to manage your children’s online activity and content access. You can block specific websites, filter out inappropriate content and set daily limits on computer time. You can also monitor what sites your kids visit and interact with, and even tailor different levels of protection for each child. Whether your kids are watching YouTube, chatting on Discord, or gaming with friends, it’s a simple way to keep them safe without having to hover over them every time they’re online. 

Protect every device

As we spend more time on our mobile devices, cybercriminals are following suit. A recent security report shows that 70% of fraud is now carried out through mobile channels. From phones and tablets to laptops, the mobile devices your family relies on daily are brimming with personal data. Now more than ever, we need to take steps to protect ourselves and our family. Webroot Essentials provides multi-device protection with real-time threat intelligence. Whether you’re on Android, iOS, Windows or Mac, all the devices in your household are constantly safeguarded against the latest online threats.

Strengthen your password security

Are you still using passwords like your dog’s name and 123? And what about your kids? Chances are their Roblox passwords aren’t as tough to hack as they should be. If there’s one weak link in most people’s security, it’s their passwords. Cybercriminals know that, and they’re taking full advantage. In fact, the 2025 Verizon Data Breach Investigations Report found 81% of data breaches were caused by compromised passwords. Here are some tips to keep all your family’s passwords secure.

  • Make it complicated: It’s important to create long and complex passwords and avoid using anything that’s easy to guess. That means no “Password” or “123456”. It also means no pet names or kid’s names, since hackers can often find those details on social media.
  •  Don’t recycle: Never use the same login for more than one account. It may be easier to remember, but if your username and password for one account are exposed in a data breach, hackers can use them to try and break into all your other accounts.
  • Use a password manager: Let a password manager save you some headaches by doing the hard work for you. Webroot solutions include password managers that store credentials and credit card information and automatically fill in login information, so the whole family can stay secure without having to remember every login. Be careful storing your credit card information on shared devices. You don’t want a shipment of 70,000 lollipops at your door.

Defend against social engineering scams

It’s important to stay aware of the latest online threats. Social engineering scams are designed to gain your trust and then trick you into sharing sensitive details by clicking on fake links or downloading malicious software. The most common type of social engineering is phishing. In a phishing attack, hackers pretend to be someone you trust and use fraudulent emails, texts and websites to try and steal personal information.

Scammers often use phishing to target children. They pose as friends, influencers, or game platforms to trick them into clicking fake links and handing over details like credit card numbers. These scams often start with an offer of an exciting reward or a prize. Take some time to talk with your kids about these common scams.

  • Fake game reward scams: Kids are offered free in-game currency on a popular platform like Fortnite, then asked to click phony links and provide sensitive details. It’s important to remind your children to redeem rewards through official game platforms only and never enter login or payment information into random pop-ups or suspicious links.
  • Social media impersonation scams: Scammers create fake social media profiles to pose as a friend, classmate, or influencer, and use stolen photos or AI-generated content to build seemingly legitimate profiles. The goal is to trick kids into clicking dangerous links or downloading malware. Make sure your children know that even if someone looks familiar, they may not be who they say they are.
  • Friendship and romance scams: A scammer builds an emotional connection with a child, then starts asking for sensitive info like Social Security numbers, photos, or money. Remind your kids that if someone won’t use video chat or meet in person, they’re probably not legitimate. Also remind your children, adding people to your social media friends group
  • Influencer giveaway scams: Fake influencer accounts host phony contests and message “winners” asking for a fee or bank account details. Remind your kids that they should only follow verified social media accounts, and that a real contest won’t ask them to pay to redeem a prize.

Secure your home network

Home security means more than just deadbolts and alarms. With smart TVs, video doorbells, and wireless thermostats, our homes are more connected than ever. While all these Internet of Things (IoT) devices making our lives more convenient, each one is a potential entry point for hackers. Webroot Secure VPN provides encrypted connections for safe browsing at home. When your family is on the go, it protects your online privacy on unsecured networks and shields your personal information from cyberthieves.

Internet safety checklist

  • Update all your operating systems and applications to the latest versions – make sure to do the same for your kids.
  • Enable automatic updates for software and security for the entire family.
  • Run a full system scan to detect any existing malware on all devices in your household.
  • Enable multi-factor authentication on all critical accounts.
  • Create unique passwords for each online account.
  • Change passwords for your family’s most important accounts often, such as banking, email, and social media.
  • Review settings on all social media accounts and make sure all kids’ profiles are private.
  • Check app permissions, especially on your kids’ devices.
  • Clear all browser cookies and caches monthly.
  • Be cautious with suspicious links or unknown senders. Be sure the whole family knows to verify sender addresses before responding to requests for information or clicking any links.
  • Consider comprehensive online security with Webroot Total Protection, which includes antivirus and identity protection, unlimited cloud backup, and up to $1 million in identity theft expense reimbursement. Get protection for up to ten devices and peace of mind that your family’s digital lives are secure.

Cybercriminals never take a break and neither should you. Internet Safety Month is the perfect opportunity to step up the digital safety of your entire household. And remember – online security isn’t just an annual event. Your sensitive data deserves year-round protection, and you can get it with family-friendly solutions from Webroot. Don’t wait for a data breach or other disaster to take action. Keep your kids safe and your data secure by strengthening your digital defenses today!

The danger of data breaches — what you really need to know

22 April 2025 at 17:09

In today’s digital world, your personal data is like cold hard cash, and that’s why cyberthieves are always looking for ways to steal it. Whether it’s an email address, a credit card number, or even medical records, your personal information is incredibly valuable in the wrong hands.

For hackers, breaking into a company database is like hitting the mother lode, giving them access to millions of personal records. Why? Because whether you know it or not, many companies are collecting and storing your private data. Think about all the information you hand over when you order something online, like your full name, your credit card number, your home address, and maybe even your birthdate just to snag an extra discount. If a company you do business with becomes part of a data breach, cybercriminals may have full access to your confidential information.

Unfortunately, data breaches are on the rise and affecting more companies and consumers than ever. In 2024, more than 1.3 billion people received notices that their information was exposed in a data breach. Chances are you’ve received at least one of these letters, which means you have been put at risk for identity theft and major financial losses.

What are data breaches and how do they happen?

Data breaches occur when sensitive, protected, or confidential data is hacked or leaked from a company or organization. Sometimes businesses are targeted because they have outdated or weak security. While no industry is immune, some sectors are more likely to become victims of breaches because of the sensitive nature of the data they handle. Here are some of the most likely targets for access to consumer data:

  • Healthcare organizations: Healthcare companies are a prime target for cybercrime due to the large amounts of sensitive data they store, which includes personal information and medical records. In 2024, there were 14 data breaches involving 1 million or more healthcare records. The largest breach affected an estimated 190 million people and a ransom of 22 million dollars was collected by the hackers.
  • Financial services industry: Banks, insurance companies and other financial organizations offer a wealth of opportunity for hackers who can use stolen bank account and credit card information for their own financial gain. In 2024, mortgage lender LoanDepot was the victim of a cyberattack that compromised the information of more than 16 million individuals.
  • Retail and e-commerce: Retail and ecommerce businesses are vulnerable to breaches because they handle and store vast amounts of customer payment information, including addresses, credit card numbers and more. Many retailers operate both brick-and-mortar stores and ecommerce platforms and rely on a variety of mobile apps, PoS (point-of-sale) systems, and cloud-based platforms, which creates more entry points for hackers to exploit.
  • Tech companies: With access to user data, software systems and intellectual property, tech firms are frequent targets. Apple, Twitter and Meta have all reportedly been victims of cyberattacks.
  • Government agencies: Because government organizations store highly sensitive information, social security numbers, they are considered especially high-value targets for cyberattacks.

The most-wanted data

The type of information stolen in data breaches varies depending on the organization, but here’s a list of the kind of data cybercriminals are seeking:

  • Emails and passwords
  • Payment and credit card information
  • Medical records and health data
  • Social Security numbers
  • Driver’s license numbers
  • Banking details and account numbers

What hackers do with your data

Once data is exposed in a breach, cybercriminals will test your usernames and password combinations across thousands of sites, knowing that most people recycle their emails and passwords. Here are just some of the ways hackers exploit your stolen information:

  • Identity theft: Hackers use your personal info to impersonate you. They can open accounts in your name, apply for loans, and even file false tax returns.
  • Selling it on the dark web: Stolen data is frequently sold to the highest bidder on dark web marketplaces. This makes it accessible to a worldwide network of criminals.
  • Phishing and social engineering: Using your personal information, scammers can craft more convincing phishing emails or messages to trick you into giving up even more sensitive details, like passwords and PIN numbers.
  • Financial exploitation: When your credit card numbers or bank account details are compromised, cyber thieves can use that information to make financial transactions in your name. They can rack up charges on your credit cards and even drain your bank accounts.
  • Data reuse and repurposing: It’s important to remember that your stolen information can be used for fraud and theft even years after a data breach, so it’s crucial to stop using recycled usernames and passwords on both old and new accounts or systems.
  • Hijacking online accounts: If your login credentials (usernames and passwords) are leaked, all your online accounts are put at risk. Besides your financial accounts, cyber thieves can also access your social media accounts and other platforms, leading to a major loss of privacy in addition to monetary losses.

How to minimize the risks

  • Stay alert: Be on the lookout for any signs of fraud and use an identity protection plan to guard against suspicious activity. Webroot Total Protection monitors the dark web for you and sends alerts if your email or personal information has been found in a breach.
  • Use strong, unique passwords: Strong, unique passwords are a simple, yet powerful security tool. Webroot Essentials plans offer password managers that do the hard work for you, keeping all your passwords safe and encrypted while you remember just one password for a quick and seamless login on every site and app.
  • Enable two-factor authentication (2FA): Turn on two-factor identification wherever possible, especially for financial accounts and email. This adds an extra step to your login process and makes it much harder for hackers to gain access. Also, remember to update and reset your passwords on a regular basis and always delete any old, unused online accounts.
  • Keep your devices protected: Always keep your device software updated and use antivirus and internet security software. Webroot Premium protects your devices from malware, viruses and phishing attempts and provides identity protection so you’re immediately alerted if your information is leaked in a data breach or found on the dark web. If you do become a victim of identity theft, you’ll have 24/7 U.S.-based customer support and up to $1 million in expense reimbursement.
  • Update your identity protection plan: Remember to keep your identity protection plan updated, so your personal details like birthdate, Social Security number and driver’s license number are current. Make sure all your family members are onboarded, especially children and older relatives. Also, get real time fraud detection by setting up threshold alerts on your financial accounts so you’re notified of any suspicious transactions as soon as they occur.
  • Monitor constantly: It’s important to remember that even if your personal data was exposed years ago, it can still resurface and cause problems at any time. Especially when it comes to children and the elderly, suspicious financial activity can happen without their knowledge and go undetected. For example, it’s not uncommon for a young student to find out they have a poor credit score only when they to try to open their first credit card account. The student had no idea that a cybercriminal used their information for fraudulent purposes and is forced to go through a difficult and costly process to restore their good credit. Most identity protection plans include monitoring and remediation, even if the fraud happened years ago and is affecting you or your family today.

Data breaches are a fact of life in the digital world we live in, but you can protect yourself with some smart security measures. By using strong passwords, password managers, antivirus software, and identity protection plans, you can reduce your risk of becoming a victim of cybercrime, and even get help to restore your identity, your financial losses and your reputation.

It’s like putting a lock on your personal data. When it comes to your sensitive information, it’s always better to be safe than sorry.

EvilNominatus Ransomware

As part of our monitoring of malicious files in current use, we detected a malicious BAT file that was uploaded to VirusTotal from Iran. This file executes a ransomware that we associated with the EvilNominatus ransomware, initially exposed at the end of 2021. It seems that the ransomware’s developer is a young Iranian, who bragged about its development on Twitter.

At this point, we have no details regarding any victims of this ransomware. We publish this research due to the malware’s unique method of operation, and the low number of AV engines capable of detecting it.

The original BAT file the research is based on was only detected by two AV engines on VirusTotal. Another BAT file that was discovered later, which shares characteristics with the first one, wasn’t detected by any AV engines. Other files that were either generated by the BAT files or communicated with them to carry out attacks were detected by multiple AV engines. Therefore, we assess that the tool’s general level of risk is low at this point.

Satan ransomware rebrands as 5ss5c ransomware

By: Bart
14 January 2020 at 23:48

The cybercrime group that brought us Satan, DBGer and Lucky ransomware and perhaps Iron ransomware, has now come up with a new version or rebranding named "5ss5c".

In a previous blog post, Satan ransomware adds EternalBlue exploit, I described how the group behind Satan ransomware has been actively developing its ransomware, adding new functionalities (specifically then: EternalBlue) and techniques with each run. Then, it appeared the group halted operations on at least the ransomware front for several months.

However, as it turns out, the group has been working on new ransomware - 5ss5c - since at least November 2019.

The following tweet got my attention:

🧐Unknown #Ransomware captured tonight from #China, Encrypt only compressed files.
Email:5ss5c@mail.ru
ext:.5ss5c
IP:61.186.243.2 58.221.158.90@demonslay335 @Amigo_A_ @GrujaRS @BleepinComputer @Rmy_Reserve @VK_Intel pic.twitter.com/dTdgnMfoLX
— onion (@jishuzhain) January 12, 2020

After some quick checks, it appears this is a downloader for the 5ss5c ransomware, which is extremely reminiscent of how Satan ransomware operated:

Figure 1 - 5ss5c downloader












The malware will leverage certutil and even contains logging:

Figure 2 - certutil logging









It will download and leverage:

  • Spreader (EternalBlue and hardcoded credentials);
  • Mimikatz and what appears another password dumper/stealer;
  • The actual ransomware.

The following hashes are relevant to this new variant:

Name: down.txt
URL: http://58.221.158[.]90:88/car/down.txt
Purpose: Downloader

VirusTotal report:
ddfd1d60ffea333a1565b0707a7adca601dafdd7ec29c61d622732117416545f

down.txt is, as mentioned, the downloader for the spreader module and for the actual ransomware:

Name: c.dat
URL: http://58.221.158[.]90:88/car/c.dat
Purpose: spreader

VirusTotal report:
ca154fa6ff0d1ebc786b4ea89cefae022e05497d095c2391331f24113aa31e3c
Fun fact: file version information contains "TODO: 5SS5C Encoder".

The compilation times are sequential, which makes sense - the downloader has been developed (and compiled) first, then the spreader and the actual ransomware.

Note that cpt.exe as filename has already been observed in Satan ransomware.

Further indicators, such as hashes, URLs, file paths and so on will be posted at the end of this blog post.


5ss5c - still in development - and with oddities

There's quite some curiosities that indicate 5ss5c is still in active development and stems from Satan ransomware, for example:

  • There are several logs created, e.g. there is a file "C:\Program Files\Common Files\System\Scanlog" that simply logs whether IPC SMB is open/available;
  • Certutil logging (successful download or not);
  • There are several Satan ransomware artefacts;
  • Other Tactics, Techniques and Procedures (TTP) align with both Satan (and DBGer), and slightly overlap with Iron: 
    • One of these is, for example, the use of multiple packers to protect their droppers and payloads. 
    • This time however, they decided to use both MPRESS and Enigma, and even Enigma VirtualBox! (Note: Enigma and Enigma VirtualBox are not the same - the latter is a virtualised packer and also referred to as EnigmaVM.)


However, there are quite some curiosities, one of them being what appear to be hardcoded credentials:

Figure 3 - Hardcoded creds




















These hardcoded credentials will be leveraged in an attempt to connect to an SQL database with the xp_cmdshell command:

Curiously, we can identify the following data inside the ransomware in regards to the SQL database:
  • ecology.url
  • ecology.password
  • ecology.user
Searching a bit further, we can discover a company named Finereport (https://www.finereport.com/en/company), which claims to be "Top 1 in China’s BI market share in IDC "China BI Software Tracker, 2018". You guessed it - it uses SQL as database.

What else is new is, as mentioned before, the use of Enigma VirtualBox for packing an additional spreader module, aptly named poc.exe. This suggest they may be experimenting (poc often is an acronym for proof of concept).

This file will be dropped to C:\ProgramData\poc.exe and will run the following command:

cd /D C:\ProgramData&star.exe --OutConfig a --TargetPort 445 --Protocol SMB --Architecture x64 --Function RunDLL --DllPayload C:\ProgramData\down64.dll --TargetIp 
Now compare this to Satan ransomware's command:

cmd /c cd /D C:\Users\Alluse~1\&blue.exe --TargetIp & star.exe --OutConfig a --TargetPort 445 --Protocol SMB --Architecture x64 --Function RunDLL --DllPayload down64.dll --TargetIp 
Something looks similar here... :-)


5ss5c ransomware - how it operates

Back to the actual ransomware. It will create the following mutexes:
  • SSSS_Scan (in previous iterations SSS_Scan has also been observed)
  • 5ss5c_CRYPT

Just like its predecessor, 5ss5c also has an exclusion list, where it will not encrypt specific files as well as files in the following folders:

Figure 4 - Exclusion list

















For example, the following folders belonging to Qihoo 360 (an internet security company based in China also offering antivirus) were already excluded in Satan and DBGer ransomware:

  • 360rec
  • 360sec
  • 360sand


While these are new in 5ss5c ransomware:

  • 360downloads
  • 360safe


As in previous iterations, 5ss5c ransomware will stop database-related services and processes.

It will however only encrypt files with the following extensions:
7z, bak, cer, csv, db, dbf, dmp, docx, eps, ldf, mdb, mdf, myd, myi, ora, pdf, pem, pfx, ppt, pptx, psd, rar, rtf, sql, tar, txt, vdi, vmdk, vmx, xls, xlsx, zip
This extension list is not like before, and includes mostly documents, archives, database files and VMware-related extensions such as vmdk.

The ransomware will then create the following URI structure to communicate with the C2 server (61.186.243[.]2):

  • /api/data.php?code=
  • &file=
  • &size=
  • &status=
  • &keyhash=
It will also create a ransomware note on the C:\ drive as: _如何解密我的文件_.txt which translates to _How to decrypt my file_.txt. Example content is as follows:

Figure 5 - ransom note














The content reads:


部分文件已经被加密
如果你想找回加密文件,发送 (1) 个比特币到我的钱包
从加密开始48小时之内没有完成支付,解密的金额会发生翻倍.
如果有其他问题,可以通过邮件联系我

您的解密凭证是 :
Email:[5ss5c@mail.ru]

Translated:

Some files have been encrypted
If you want to retrieve the encrypted file, send (1) Bitcoins to my wallet
If payment is not completed within 48 hours from the start of encryption, the amount of decryption will double.
If you have other questions, you can contact me by email
Your decryption credentials are:
Email: [5ss5c@mail.ru]

Interestingly, the ransomware note does not contain a Bitcoin address. Additionally, the note only contains instructions in Chinese, not Korean nor English like previous iterations. Is 5ss5c ransomware more targeted, or just actively being tested by the group/developers behind it?

Encrypted files will have the actor's email address prepended and a unique token with the ransomware's name will be appended, for example;
test.txt becomes [5ss5c@mail.ru]test.txt.Y54GUHKIG1T2ZLN76II9F3BBQV7MK4UOGSQUND7U.5ss5c.


Prevention
  • Enable UAC;
  • Enable Windows Update, and install updates (especially verify if MS17-010 is installed);
  • Install an antivirus, and keep it up-to-date and running;
  • Install a firewall, or enable the Windows Firewall;
  • Restrict, where possible, access to shares (ACLs);
  • Create backups! (and test them)
More ransomware prevention can be found here.

Conclusion

Satan is dead, long live 5ss5c! It just doesn't sound as good, does it?

Whoever's behind the development of Satan, DBGer, Lucky and likely Iron ransomware, is back in business with the 5ss5c ransomware, and it appears to be in active development - and is trying to increase (or perhaps focus?) its targeting and spread of the ransomware.

It is recommended organisations detect and/or search for the indicators of compromise (IOCs) below, and have proper prevention controls in place. MITRE ATT&CK IDs can also be found below.
