Introduction

Stan Ghouls (also known as Bloody Wolf) is an cybercriminal group that has been launching targeted attacks against organizations in Russia, Kyrgyzstan, Kazakhstan, and Uzbekistan since at least 2023. These attackers primarily have their sights set on the manufacturing, finance, and IT sectors. Their campaigns are meticulously prepared and tailored to specific victims, featuring a signature toolkit of custom Java-based malware loaders and a sprawling infrastructure with resources dedicated to specific campaigns.

We continuously track Stan Ghouls’ activity, providing our clients with intel on their tactics, techniques, procedures, and latest campaigns. In this post, we share the results of our most recent deep dive into a campaign targeting Uzbekistan, where we identified roughly 50 victims. About 10 devices in Russia were also hit, with a handful of others scattered across Kazakhstan, Turkey, Serbia, and Belarus (though those last three were likely just collateral damage).

During our investigation, we spotted shifts in the attackers’ infrastructure – specifically, a batch of new domains. We also uncovered evidence suggesting that Stan Ghouls may have added IoT-focused malware to their arsenal.

Technical details

Threat evolution

Stan Ghouls relies on phishing emails packed with malicious PDF attachments as their initial entry point. Historically, the group’s weapon of choice was the remote access Trojan (RAT) STRRAT, also known as Strigoi Master. Last year, however, they switched strategies, opting to misuse legitimate software, NetSupport, to maintain control over infected machines.

Given Stan Ghouls’ targeting of financial institutions, we believe their primary motive is financial gain. That said, their heavy use of RATs may also hint at cyberespionage.

Like any other organized cybercrime groups, Stan Ghouls frequently refreshes its infrastructure. To track their campaigns effectively, you have to continuously analyze their activity.

Initial infection vector

As we’ve mentioned, Stan Ghouls’ primary – and currently only – delivery method is spear phishing. Specifically, they favor emails loaded with malicious PDF attachments. This has been backed up by research from several of our industry peers (1, 2, 3). Interestingly, the attackers prefer to use local languages rather than opting for international mainstays like Russian or English. Below is an example of an email spotted in a previous campaign targeting users in Kyrgyzstan.

The email is written in Kyrgyz and translates to: “The service has contacted you. Materials for review are attached. Sincerely”.

The attachment was a malicious PDF file titled “Постановление_Районный_суд_Кчрм_3566_28-01-25_OL4_scan.pdf” (the title, written in Russian, posed it as an order of district court).

During the most recent campaign, which primarily targeted victims in Uzbekistan, the attackers deployed spear-phishing emails written in Uzbek:

The email text can be translated as follows:

[redacted] AKMALZHON IBROHIMOVICH

You will receive a court notice. Application for retrial. The case is under review by the district court. Judicial Service.

Mustaqillik Street, 147 Uraboshi Village, Quva District.

The attachment, named E-SUD_705306256_ljro_varaqasi.pdf (MD5: 7556e2f5a8f7d7531f28508f718cb83d), is a standard one-page decoy PDF:

Notice that the attackers claim that the “case materials” (which are actually the malicious loader) can only be opened using the Java Runtime Environment.

They even helpfully provide a link for the victim to download and install it from the official website.

The malicious loader

The decoy document contains identical text in both Russian and Uzbek, featuring two links that point to the malicious loader:

• Uzbek link (“- Ish materiallari 09.12.2025 y”): hxxps://mysoliq-uz[.]com/api/v2/documents/financial/Q4-2025/audited/consolidated/with-notes/financials/reports/annual/2025/tashkent/statistical-statements/
• Russian link (“- Материалы дела 09.12.2025 г.”): hxxps://my-xb[.]com/api/v2/documents/financial/Q4-2025/audited/consolidated/with-notes/financials/reports/annual/2025/tashkent/statistical-statements/

Both links lead to the exact same JAR file (MD5: 95db93454ec1d581311c832122d21b20).

It’s worth noting that these attackers are constantly updating their infrastructure, registering new domains for every new campaign. In the relatively short history of this threat, we’ve already mapped out over 35 domains tied to Stan Ghouls.

The malicious loader handles three main tasks:

1. Displaying a fake error message to trick the user into thinking the application can’t run. The message in the screenshot translates to: “This application cannot be run in your OS. Please use another device.”
   

   Fake error message

2. Checking that the number of previous RAT installation attempts is less than three. If the limit is reached, the loader terminates and throws the following error: “Urinishlar chegarasidan oshildi. Boshqa kompyuterni tekshiring.” This translates to: “Attempt limit reached. Try another computer.”
   

   The limitCheck procedure for verifying the number of RAT download attempts

3. Downloading a remote management utility from a malicious domain and saving it to the victim’s machine. Stan Ghouls loaders typically contain a list of several domains and will iterate through them until they find one that’s live.
   

   The performanceResourceUpdate procedure for downloading the remote management utility

The loader fetches the following files, which make up the components of the NetSupport RAT: PCICHEK.DLL, client32.exe, advpack.dll, msvcr100.dll, remcmdstub.exe, ir50_qcx.dll, client32.ini, AudioCapture.dll, kbdlk41a.dll, KBDSF.DLL, tcctl32.dll, HTCTL32.DLL, kbdibm02.DLL, kbd101c.DLL, kbd106n.dll, ir50_32.dll, nskbfltr.inf, NSM.lic, pcicapi.dll, PCICL32.dll, qwave.dll. This list is hardcoded in the malicious loader’s body. To ensure the download was successful, it checks for the presence of the client32.exe executable. If the file is found, the loader generates a NetSupport launch script (run.bat), drops it into the folder with the other files, and executes it:

The loader also ensures NetSupport persistence by adding it to startup using the following three methods:

1. It creates an autorun script named SoliqUZ_Run.bat and drops it into the Startup folder (%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup):
   

   The generateAutorunScript procedure for creating the batch file and placing it in the Startup folder

2. It adds the run.bat file to the registry’s autorun key (HKCU\Software\Microsoft\Windows\CurrentVersion\Run\malicious_key_name).
   

   The registryStartupAdd procedure for adding the RAT launch script to the registry autorun key

3. It creates a scheduled task to trigger run.bat using the following command:
   schtasks Create /TN "[malicious_task_name]" /TR "[path_to_run.bat]" /SC ONLOGON /RL LIMITED /F /RU "[%USERNAME%]"
   

   The installStartupTask procedure for creating a scheduled task to launch the NetSupport RAT (via run.bat)

Once the NetSupport RAT is downloaded, installed, and executed, the attackers gain total control over the victim’s machine. While we don’t have enough telemetry to say with 100% certainty what they do once they’re in, the heavy focus on finance-related organizations suggests that the group is primarily after its victims’ money. That said, we can’t rule out cyberespionage either.

Malicious utilities for targeting IoT infrastructure

Previous Stan Ghouls attacks targeting organizations in Kyrgyzstan, as documented by Group-IB researchers, featured a NetSupport RAT configuration file client32.ini with the MD5 hash cb9c28a4c6657ae5ea810020cb214ff0. While reports mention the Kyrgyzstan campaign kicked off in June 2025, Kaspersky solutions first flagged this exact config file on May 16, 2025. At that time, it contained the following NetSupport RAT command-and-control server info:

...
[HTTP]
CMPI=60
GatewayAddress=hgame33[.]com:443
GSK=FN:L?ADAFI:F?BCPGD;N>IAO9J>J@N
Port=443
SecondaryGateway=ravinads[.]com:443
SecondaryPort=443

At the time of our January 2026 investigation, our telemetry showed that the domain specified in that config, hgame33[.]com, was also hosting the following files:

• hxxp://www.hgame33[.]com/00101010101001/morte.spc
• hxxp://hgame33[.]com/00101010101001/debug

• hxxp://hgame33[.]com/00101010101001/morte.mips

All of these files belong to the infamous IoT malware named Mirai. Since they are sitting on a server tied to the Stan Ghouls’ campaign targeting Kyrgyzstan, we can hypothesize – with a low degree of confidence – that the group has expanded its toolkit to include IoT-based threats. However, it’s also possible it simply shared its infrastructure with other threat actors who were the ones actually wielding Mirai. This theory is backed up by the fact that the domain’s registration info was last updated on July 4, 2025, at 11:46:11 – well after Stan Ghouls’ activity in May and June.

Attribution

We attribute this campaign to the Stan Ghouls (Bloody Wolf) group with a high degree of confidence, based on the following similarities to the attackers’ previous campaigns:

1. Substantial code overlaps were found within the malicious loaders. For example:
   

   Code snippet from sample 1acd4592a4eb0c66642cc7b07213e9c9584c6140210779fbc9ebb76a90738d5e, the loader from the Group-IB report

   

   Code snippet from sample 95db93454ec1d581311c832122d21b20, the NetSupport loader described here

2. Decoy documents in both campaigns look identical.

   Decoy document 106911ba54f7e5e609c702504e69c89a used in the campaign described here

3. In both current and past campaigns, the attackers utilized loaders written in Java. Given that Java has fallen out of fashion with malicious loader authors in recent years, it serves as a distinct fingerprint for Stan Ghouls.

Victims

We identified approximately 50 victims of this campaign in Uzbekistan, alongside 10 in Russia and a handful of others in Kazakhstan, Turkey, Serbia, and Belarus (we suspect the infections in these last three countries were accidental). Nearly all phishing emails and decoy files in this campaign were written in Uzbek, which aligns with the group’s track record of leveraging the native languages of their target countries.

Most of the victims are tied to industrial manufacturing, finance, and IT. Furthermore, we observed infection attempts on devices within government organizations, logistics companies, medical facilities, and educational institutions.

It is worth noting that over 60 victims is quite a high headcount for a sophisticated campaign. This suggests the attackers have enough resources to maintain manual remote control over dozens of infected devices simultaneously.

Takeaways

In this post, we’ve broken down the recent campaign by the Stan Ghouls group. The attackers set their sights on organizations in industrial manufacturing, IT, and finance, primarily located in Uzbekistan. However, the ripple effect also reached Russia, Kazakhstan, and a few, likely accidental, victims elsewhere.

With over 60 targets hit, this is a remarkably high volume for a sophisticated targeted campaign. It points to the significant resources these actors are willing to pour into their operations. Interestingly, despite this, the group sticks to a familiar toolkit including the legitimate NetSupport remote management utility and their signature custom Java-based loader. The only thing they seem to keep updating is their infrastructure. For this specific campaign, they employed two new domains to house their malicious loader and one new domain dedicated to hosting NetSupport RAT files.

One curious discovery was the presence of Mirai files on a domain linked to the group’s previous campaigns. This might suggest Stan Ghouls are branching out into IoT malware, though it’s still too early to call it with total certainty.

We’re keeping a close watch on Stan Ghouls and will continue to keep our customers in the loop regarding the group’s latest moves. Kaspersky products provide robust protection against this threat at every stage of the attack lifecycle.

   Code snippet from sample 95db93454ec1d581311c832122d21b20, the NetSupport loader described here

2. Decoy documents in both campaigns look identical.

3. In both current and past campaigns, the attackers utilized loaders written in Java. Given that Java has fallen out of fashion with malicious loader authors in recent years, it serves as a distinct fingerprint for Stan Ghouls.

Victims

We identified approximately 50 victims of this campaign in Uzbekistan, alongside 10 in Russia and a handful of others in Kazakhstan, Turkey, Serbia, and Belarus (we suspect the infections in these last three countries were accidental). Nearly all phishing emails and decoy files in this campaign were written in Uzbek, which aligns with the group’s track record of leveraging the native languages of their target countries.

Most of the victims are tied to industrial manufacturing, finance, and IT. Furthermore, we observed infection attempts on devices within government organizations, logistics companies, medical facilities, and educational institutions.

It is worth noting that over 60 victims is quite a high headcount for a sophisticated campaign. This suggests the attackers have enough resources to maintain manual remote control over dozens of infected devices simultaneously.

Takeaways

In this post, we’ve broken down the recent campaign by the Stan Ghouls group. The attackers set their sights on organizations in industrial manufacturing, IT, and finance, primarily located in Uzbekistan. However, the ripple effect also reached Russia, Kazakhstan, and a few, likely accidental, victims elsewhere.

With over 60 targets hit, this is a remarkably high volume for a sophisticated targeted campaign. It points to the significant resources these actors are willing to pour into their operations. Interestingly, despite this, the group sticks to a familiar toolkit including the legitimate NetSupport remote management utility and their signature custom Java-based loader. The only thing they seem to keep updating is their infrastructure. For this specific campaign, they employed two new domains to house their malicious loader and one new domain dedicated to hosting NetSupport RAT files.

One curious discovery was the presence of Mirai files on a domain linked to the group’s previous campaigns. This might suggest Stan Ghouls are branching out into IoT malware, though it’s still too early to call it with total certainty.

We’re keeping a close watch on Stan Ghouls and will continue to keep our customers in the loop regarding the group’s latest moves. Kaspersky products provide robust protection against this threat at every stage of the attack lifecycle.

Researchers have demonstrated remotely controlling a wheelchair over Bluetooth. CISA has issued an advisory.

CISA said the WHILL wheelchairs did not enforce authentication for Bluetooth connections, allowing an attacker who is in Bluetooth range of the targeted device to pair with it. The attacker could then control the wheelchair’s movements, override speed restrictions, and manipulate configuration profiles, all without requiring credentials or user interaction.

Introduction

Imagine you’re cruising down the highway in your brand-new electric car. All of a sudden, the massive multimedia display fills with Doom, the iconic 3D shooter game. It completely replaces the navigation map or the controls menu, and you realize someone is playing it remotely right now. This is not a dream or an overactive imagination – we’ve demonstrated that it’s a perfectly realistic scenario in today’s world.

The internet of things now plays a significant role in the modern world. Not only are smartphones and laptops connected to the network, but also factories, cars, trains, and even airplanes. Most of the time, connectivity is provided via 3G/4G/5G mobile data networks using modems installed in these vehicles and devices. These modems are increasingly integrated into a System-on-Chip (SoC), which uses a Communication Processor (CP) and an Application Processor (AP) to perform multiple functions simultaneously. A general-purpose operating system such as Android can run on the AP, while the CP, which handles communication with the mobile network, typically runs on a dedicated OS. The interaction between the AP, CP, and RAM within the SoC at the microarchitecture level is a “black box” known only to the manufacturer – even though the security of the entire SoC depends on it.

Bypassing 3G/LTE security mechanisms is generally considered a purely academic challenge because a secure communication channel is established when a user device (User Equipment, UE) connects to a cellular base station (Evolved Node B, eNB). Even if someone can bypass its security mechanisms, discover a vulnerability in the modem, and execute their own code on it, this is unlikely to compromise the device’s business logic. This logic (for example, user applications, browser history, calls, and SMS on a smartphone) resides on the AP and is presumably not accessible from the modem.

To find out, if that is true, we conducted a security assessment of a modern SoC, Unisoc UIS7862A, which features an integrated 2G/3G/4G modem. This SoC can be found in various mobile devices by multiple vendors or, more interestingly, in the head units of modern Chinese vehicles, which are becoming increasingly common on the roads. The head unit is one of a car’s key components, and a breach of its information security poses a threat to road safety, as well as the confidentiality of user data.

During our research, we identified several critical vulnerabilities at various levels of the Unisoc UIS7862A modem’s cellular protocol stack. This article discusses a stack-based buffer overflow vulnerability in the 3G RLC protocol implementation (CVE-2024-39432). The vulnerability can be exploited to achieve remote code execution at the early stages of connection, before any protection mechanisms are activated.

Importantly, gaining the ability to execute code on the modem is only the entry point for a complete remote compromise of the entire SoC. Our subsequent efforts were focused on gaining access to the AP. We discovered several ways to do so, including leveraging a hardware vulnerability in the form of a hidden peripheral Direct Memory Access (DMA) device to perform lateral movement within the SoC. This enabled us to install our own patch into the running Android kernel and execute arbitrary code on the AP with the highest privileges. Details are provided in the relevant sections.

Acquiring the modem firmware

The modem at the center of our research was found on the circuit board of the head unit in a Chinese car.

Description of the circuit board components:

Number in the board photo	Component
1	Realtek RTL8761ATV 802.11b/g/n 2.4G controller with wireless LAN (WLAN) and USB interfaces (USB 1.0/1.1/2.0 standards)
2	SPRD UMW2652 BGA WiFi chip
3	55966 TYADZ 21086 chip
4	SPRD SR3595D (Unisoc) radio frequency transceiver
5	Techpoint TP9950 video decoder
6	UNISOC UIS7862A
7	BIWIN BWSRGX32H2A-48G-X internal storage, Package200-FBGA, ROM Type – Discrete, ROM Size – LPDDR4X, 48G
8	SCY E128CYNT2ABE00 EMMC 128G/JEDEC memory card
9	SPREADTRUM UMP510G5 power controller
10	FEI.1s LE330315 USB2.0 shunt chip
11	SCT2432STER synchronous step-down DC-DC converter with internal compensation

Using information about the modem’s hardware, we desoldered and read the embedded multimedia memory card, which contained a complete image of its operating system. We then analyzed the image obtained.

Remote access to the modem (CVE-2024-39431)

The modem under investigation, like any modern modem, implements several protocol stacks: 2G, 3G, and LTE. Clearly, the more protocols a device supports, the more potential entry points (attack vectors) it has. Moreover, the lower in the OSI network model stack a vulnerability sits, the more severe the consequences of its exploitation can be. Therefore, we decided to analyze the data packet fragmentation mechanisms at the data link layer (RLC protocol).

We focused on this protocol because it is used to establish a secure encrypted data transmission channel between the base station and the modem, and, in particular, it is used to transmit higher-layer NAS (Non-Access Stratum) protocol data. NAS represents the functional level of the 3G/UMTS protocol stack. Located between the user equipment (UE) and core network, it is responsible for signaling between them. This means that a remote code execution (RCE) vulnerability in RLC would allow an attacker to execute their own code on the modem, bypassing all existing 3G communication protection mechanisms.

The RLC protocol uses three different transmission modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). We are only interested in UM, because in this mode the 3G standard allows both the segmentation of data and the concatenation of several small higher-layer data fragments (Protocol Data Units, PDU) into a single data link layer frame. This is done to maximize channel utilization. At the RLC level, packets are referred to as Service Data Units (SDU).

Among the approximately 75,000 different functions in the firmware, we found the function for handling an incoming SDU packet. When handling a received SDU packet, its header fields are parsed. The packet itself consists of a mandatory header, optional headers, and data. The number of optional headers is not limited. The end of the optional headers is indicated by the least significant bit (E bit) being equal to 0. The algorithm processes each header field sequentially, while their E-bits equal 1. During processing, data is written to a variable located on the stack of the calling function. The stack depth is 0xB4 bytes. The size of the packet that can be parsed (i.e., the number of headers, each header being a 2-byte entry on the stack) is limited by the SDU packet size of 0x5F0 bytes.

As a result, exploitation can be achieved using just one packet in which the number of headers exceeds the stack depth (90 headers). It is important to note that this particular function lacks a stack canary, and when the stack overflows, it is possible to overwrite the return address and some non-volatile register values in this function. However, overwriting is only possible with a value ending in one in binary (i.e., a value in which the least significant bit equals 1). Notably, execution takes place on ARM in Thumb mode, so all return addresses must have the least significant bit equal to 1. Coincidence? Perhaps.

In any case, sending the very first dummy SDU packet with the appropriate number of “correct” headers caused the device to reboot. However, at that moment, we had no way to obtain information on where and why the crash occurred (although we suspect the cause was an attempt to transfer control to the address 0xAABBCCDD, taken from our packet).

Gaining persistence in the system

The first and most important observation is that we know the pointer to the newly received SDU packet is stored in register R2. Return Oriented Programming (ROP) techniques can be used to execute our own code, but first we need to make sure it is actually possible.

We utilized the available AT command handler to move the data to RAM areas. Among the available AT commands, we found a suitable function – SPSERVICETYPE.

Next, we used ROP gadgets to overwrite the address 0x8CE56218 without disrupting the subsequent operation of the incoming SDU packet handling algorithm. To achieve this, it was sufficient to return to the function from which the SDU packet handler was called, because it was invoked as a callback, meaning there is no data linkage on the stack. Given that this function only added 0x2C bytes to the stack, we needed to fit within this size.

Having found a suitable ROP chain, we launched an SDU packet containing it as a payload. As a result, we saw the output 0xAABBCCDD in the AT command console for SPSERVICETYPE. Our code worked!

Next, by analogy, we input the address of the stack frame where our data was located, but it turned out not to be executable. We then faced the task of figuring out the MPU settings on the modem. Once again, using the ROP chain method, we generated code that read the MPU table, one DWORD at a time. After many iterations, we obtained the following table.

The table shows what we suspected – the code section is only mapped for execution. An attempt to change the configuration resulted in another ROP chain, but this same section was now mapped with write permissions in an unused slot in the table. Because of MPU programming features, specifically the presence of the overlap mechanism and the fact that a region with a higher ID has higher priority, we were able to write to this section.

All that remained was to use the pointer to our data (still stored in R2) and patch the code section that had just been unlocked for writing. The question was what exactly to patch. The simplest method was to patch the NAS protocol handler by adding our code to it. To do this, we used one of the NAS protocol commands – MM information. This allowed us to send a large amount of data at once and, in response, receive a single byte of data using the MM status command, which confirmed the patching success.

As a result, we not only successfully executed our own code on the modem side but also established full two-way communication with the modem, using the high-level NAS protocol as a means of message delivery. In this case, it was an MM Status packet with the cause field equaling 0xAA.

However, being able to execute our own code on the modem does not give us access to user data. Or does it?

South Korean law enforcement has arrested four suspects linked to the breach of approximately 120 000 IP cameras installed in private homes and commercial spaces — including karaoke lounges, pilates studios, and a gynecology clinic. Two of the hackers sold sexually explicit footage from the cameras through a foreign adult website. In this post, we explain what IP cameras are, and where their vulnerabilities lie. We also dive into the details of the South Korea incident and share practical advice on how to avoid becoming a target for attackers hunting for intimate video content.

How do IP cameras work?

An IP camera is a video camera connected to the internet via the Internet Protocol (IP), which lets you view its feed remotely on a smartphone or computer. Unlike traditional CCTV surveillance systems, these cameras don’t require a local surveillance hub — like you see in the movies — or even a dedicated computer to be plugged into. An IP camera streams video directly in real time to any device that connects to it over the internet. Most of today’s IP camera manufacturers also offer optional cloud storage plans, letting you access recorded footage from anywhere in the world.

In recent years, IP cameras have surged in popularity to become ubiquitous, serving a wide range of purposes — from monitoring kids and pets at home to securing warehouses, offices, short-term rental apartments (often illegally), and small businesses. Basic models can be picked up online for as little as US$25–40.

One of the defining features of IP cameras is that they’re originally designed for remote access. The camera connects to the internet and silently accepts incoming connections — ready to stream video to anyone who knows its address and has the password. And this leads to two common problems with these devices.

1. Default passwords. IP camera owners often keep the simple default usernames and passwords that come preconfigured on the device.
2. Vulnerabilities in outdated software. Software updates for cameras often require manual intervention: you need to log in to the administration interface, check for an update, and install it yourself. Many users simply skip this altogether. Worse, updates might not even exist — many camera vendors ignore security and drop support right after the sale.

What happened in South Korea?

Let’s rewind to what unfolded this fall in South Korea. Law-enforcement authorities reported a breach of roughly 120 000 IP cameras, and the arrest of four suspects in connection with the attacks. Here’s what we know about each of them.

• Suspect 1, unemployed, hacked approximately 63 000 IP cameras, producing and later selling 545 sexually explicit videos for a total of 35 million South Korean won, or just under US$24 000.
• Suspect 2, an office worker, compromised around 70 000 IP cameras and sold 648 illicit sexual videos for 18 million won (about US$12 000).
• Suspect 3, self-employed, hacked 15 000 IP cameras and created illegal content, including footage involving minors. So far, there’s no information suggesting this individual sold any material.
• Suspect 4, an office worker, appears to have breached only 136 IP cameras, and isn’t accused of producing or selling illegal content.

The astute reader may have noticed the numbers don’t quite add up — the figures above totaling well over 120 000. South Korean law enforcement hasn’t provided a clear explanation for this discrepancy. Journalists speculate that some of the devices may have been compromised by multiple attackers.

The investigation has revealed that only two of the accused actually sold the sexual content they’d stolen. However, the scale of their operation is staggering. Last year, the website hosting voyeurism and sexual exploitation content — which both perpetrators used to sell their videos — received 62% of its uploads from just these two individuals. In essence, this video enthusiast duo supplied the majority of the platform’s illegal content. It’s also been reported that three buyers of these videos were detained.

South Korean investigators were able to identify 58 specific locations of the hacked cameras. They’ve notified the victims and provided guidance on changing the passwords to secure their IP cameras. This suggests — although the investigators haven’t disclosed any details about the method of compromise — that the attackers used brute-forcing to crack the cameras’ simple passwords.

Another possibility is that the camera owners, as is often the case, simply never changed the default usernames and passwords. These default credentials are frequently widely known, so it’s entirely plausible that to gain access the attackers only needed to know the camera’s IP address and try a handful of common username and password combinations.

How to avoid becoming a victim of voyeur hackers

The takeaways from this whole South Korean dorama drama are straight from our playbook:

• Always replace the factory-set credentials with your own logins and passwords.
• Never use weak or common passwords — even for seemingly harmless accounts or gadgets. You don’t have to work at the Louvre to be a target. You never know which credentials attackers will try to crack, or where that initial breach might lead them.
• Always set unique passwords. If you reuse passwords, a single data leak from one service can put all your other accounts at risk.

These rules are universal: they apply just as much to your social media and banking accounts as they do to your robot vacuums, IP cameras, and every other smart device in your home.

To keep all those unique passwords organized without losing your mind, we strongly recommend a reliable password manager. Kaspersky Password Manager can both store all your credentials securely and generate truly random, complex, and uncrackable passwords for you. With it, you can be confident that no one will guess the passwords to your accounts or devices. Plus, it helps you generate one-time codes for two-factor authentication, save and autofill passkeys, and sync your sensitive data — not just logins and passwords, but also bank card details, documents, and even private photos — in encrypted form across all your devices.
