Anthropic's super bug-hunting model Mythos is hardcore good at math, as latest vuln under attack shows

3 October 2026 at 17:27
The second Anthropic-linked vulnerability known to have been exploited in the wild saw initial activity from an IP address in China targeting vulnerable hosts in the US and Japan. The vuln is a critical authentication-bypass bug in Rejetto HTTP File Server (HFS) that can lead to full admin access and remote code execution. HFS is an open source web file server that previously appeared on the US Cybersecurity and Infrastructure Security Agency’s catalog of Known Exploited Vulnerabilities in 2024. On Wednesday, researcher Zach Hanley at AI pen-testing company Horizon3 said he used Mythos to uncover a new flaw in the file server, now tracked as CVE-2026-61500. If you use Rejetto HFS, be sure to update to v3.2.1 or later, which fixes this and other security flaws. Hanley also published a video showing the steps to exploit HFS and remotely execute code on the server. By the next day, the CVE was under exploitation. “We started detecting exploitation of CVE-2026-61500 in Rejetto HFS this evening,” VulnCheck security researcher Patrick Garrity posted on LinkedIn on Thursday, adding that Hanley and team reported the bug to VulnCheck for CVE assignment. “Our canaries detected an actor in China targeting real vulnerable hosts in the US,” Garrity added. Garrity has been tracking CVEs attributed to Mythos and Project Glasswing, Anthropic’s initiative to give select partners access to the bug-hunting model, since shortly after the program was announced in April. Anthropic claims that Mythos is too powerful to release to the general public (insert evil laugh). As of Friday, Mythos and Project Glasswing have uncovered 286 CVEs, according to Garrity’s tracker, and up until Thursday only one of these bugs had been exploited in real-world attacks. The Thursday night activity originated from one IP address in China and targeted vulnerable servers in the US and Japan, Garrity told The Register. “Today we have seen four hits,” he told us on Friday. These originated from two different IP addresses in the US: 173.239.211[.]248 and 173.239.211[.]249. Both are in the same subnet, and “appear to be coming from a proxy,” Garrity added. China-linked digital intruders routinely use compromised devices as proxies to route malicious traffic and disguise the attackers’ true location, and in April a 10-country security advisory warned of China-nexus cyber operatives using proxy networks “strategically, and at scale.” In his write-up, Hanley said Horizon3 has used Mythos in its vulnerability research – and discovered “many critical vulnerabilities” – ever since the security company joined Project Glasswing in July. Mythos' mad math skillz CVE-2026-61500 highlights a couple of Mythos capabilities that make it really good at uncovering vulnerabilities, according to Hanley. Namely, Mythos excels at mathematical distillations and scientific tasks, especially those relating to computer science and operating systems. Finding this CVE “speaks to Mythos’s capabilities in understanding of mathematics, how it identified an exploitable set of cryptographic missteps, and approached solving the constraints to achieve remote code execution,” Hanley wrote. The security issue stems from how HFS authenticates users. It generates a random value with Math.random() and then passes this value to Koa, the Node.js web framework foundation for HFS. Koa uses keygrip to sign all session cookies with that random value. This means that if an “attacker can derive what the session signing key is, they can forge valid session cookies,” Hanley said. This should not be possible, assuming Math.random() uses a secure pseudo random number generator (PRNG). But V8’s Math.random() did not use a secure PRNG. Mythos discovered that the output of the xorshift128+ algorithm it used was fully reversible – and the application was leaking Math.random() outputs. The model’s analysis claimed that Z3, a Microsoft-developed, publicly available Satisfiability Modulo Theories (SMT) solver, could be used to recover the PRNG seed. Hanley notes that Horizon3’s researchers could not recall seeing an SMT solver used this way to attack a cryptographic flaw in a real application and bypass authentication. “What makes this impressive is that Mythos didn’t just flag the insecure PRNG in isolation – it simultaneously identified that the application leaked raw Math.random() outputs through a separate code path, recognized those two facts as a chain, and determined the leak produced exactly the observations needed to make state recovery feasible,” he wrote.®

Following Operation Epic Fury, regional kinetic operations have transitioned into direct, persistent threats against commercial shipping, energy infrastructure, and critical supply chains.

The Flashpoint Threat Intelligence Brief: Middle East cuts through headline noise to deliver tactical, ground-level intelligence for government agencies, corporate security leads, and global logistics teams—turning Flashpoint’s primary source intelligence into proactive risk mitigation.

Here is what your security operations team needs to track this week.

Operational SITREP: Executive Summary

Between October 16 and October 22, Ansarallah (the Houthi movement) expanded its operations against Yemeni government forces, striking the Al-Alam training center in Shabwa governorate with three ballistic missiles on October 19. Local officials reported at least 53 people killed and more than 200 wounded. Houthi forces also reportedly advanced into western Taiz city and claimed additional attacks against Saudi-aligned forces.

The United Kingdom announced it would deploy Royal Air Force (RAF) Typhoon fighter jets, an A400M transport aircraft, and military advisers to strengthen Saudi Arabia’s defenses against Houthi missile and drone attacks. The deployment comes as Saudi authorities continue responding to strikes against aviation infrastructure and other targets.

Inside Iran, reports of renewed US military strikes against Iranian facilities remained disputed. Iranian sources alleged attacks on the Kenarak naval base and an Islamic Revolutionary Guard Corps (IRGC) anti-ship missile unit in Sirik, although a US official rejected the Kenarak account and neither incident has been independently confirmed. Iran also placed border forces on maximum alert, conducted ballistic missile launches, and reinforced preparations for potential renewed hostilities.

Regional tensions extended into Iraq’s Kurdistan region, where Iranian ballistic missiles and drones struck Kurdish opposition positions near Erbil on October 21. Iraq began closing its border crossings with Iran the same day, following Pakistan’s closure of its second crossing earlier in the reporting period.

Maritime attacks continued in the Strait of Hormuz and waters off Saudi Arabia, with UKMTO reporting a tanker damaged by unknown projectiles northeast of Jubail.

In the cyber domain, Iranian authorities issued binding directives to cut domestic access to the international internet if another war begins. Separately, the Handala Hack Team claimed breaches of Israeli military units and personnel, while new research documented the use of online advertising infrastructure to deliver Candiru spyware.

Kinetic & Maritime Risk

The expansion of Houthi operations into southern Yemen adds another front to an already sustained campaign against Saudi Arabia. Beyond the October 19 strike in Shabwa, Ansarallah forces reportedly advanced into western Taiz, approaching the Old Airport neighborhood and Taiz University. The group also claimed to have downed a Saudi military helicopter near Najran, although Saudi authorities have not confirmed the loss. Meanwhile, the UK’s deployment of RAF Typhoon fighter jets and military advisers will provide additional defensive support to Saudi Arabia while increasing the number of Western military assets exposed to Houthi attacks.

Preparations for potential renewed hostilities between Iran and Israel also intensified. Iran’s reported “Code 100” maximum border alert coincided with ballistic missile activity near Urmia and an Israeli long-range strike exercise involving dozens of fighter jets and reported US aerial refueling support. Iranian sources separately alleged US strikes against military facilities at Kenarak and Sirik, although neither incident has been independently confirmed and a US official disputed the Kenarak account. Together, these developments point to heightened military readiness, even as the timing and likelihood of renewed large-scale operations remain uncertain.

Iran’s strikes against Kurdish opposition positions near Erbil introduce additional security concerns for organizations operating in Iraq’s Kurdistan region. The attacks followed Iranian statements concerning the potential expulsion or transfer of Kurdish opposition members from Iraq, while the closure of border crossings by Iraq and Pakistan further complicates overland movement and commercial logistics.

At sea, the threat extends beyond the Strait of Hormuz to waters off Saudi Arabia. UKMTO reported a tanker damaged by unknown projectiles northeast of Jubail, while separate reporting identified another tanker struck in the Red Sea. Iranian claims of additional incidents, including a purported mine strike in the Strait of Hormuz, remain unverified. The continued attacks across multiple maritime corridors complicate transit planning for commercial shipping and energy operators.

Cyber and Hybrid Risk

New research from Citizen Lab and another research group identified how Israeli digital advertising agency Discover-Tech used a capability known as AdFection to track individuals and deliver Candiru spyware through ordinary online advertisements. The operation reportedly used advertising infrastructure spanning more than 120,000 websites and 75,000 applications, with targeted devices potentially compromised simply by loading a malicious advertisement. Targets included dozens of Al Jazeera journalists, while the advertisements also reached networks associated with the UN, NATO, the International Criminal Court, and the Pentagon.

The Handala Hack Team also claimed new compromises of Israeli military entities, including a media-monitoring and analysis center it associated with Unit 8200 and the commander of the IDF’s Yahalam combat engineering unit. The group published more than 500 purportedly classified documents and tens of thousands of alleged internal messages, attributing its access in part to sensitive operational information stored on personal devices. These claims have not been independently verified.

Meanwhile, Iranian authorities issued binding directives requiring domestic access to the international internet to be cut immediately if another war begins. The order raises the prospect of significant communications disruptions for businesses and personnel operating inside Iran. A Ukrainian intelligence assessment also reported cooperation between Russian and Iranian hacking groups targeting Israeli infrastructure, while Iranian opposition activists warned of a suspicious Telegram account impersonating Israeli military intelligence to solicit personal information and documents.

Recommended Risk Posture and Protective Controls

Organizations with personnel, facilities, or operations exposed to the conflict should reassess physical security, travel arrangements, maritime operations, and cyber defenses.

Cyber Defense

  • Reduce exposure to malicious advertising: Review browser and network-level ad blocking, mobile device security, and spyware response procedures, particularly for journalists, government personnel, and other high-risk individuals.
  • Prepare for hack-and-leak activity: Organizations with Israeli government or defense ties should review incident-response and communications plans and reinforce policies against storing sensitive operational information on unmanaged personal devices.
  • Establish contingency communications: Organizations with staff, contractors, or partners in Iran should prepare alternate communication and check-in procedures that do not rely on international internet connectivity.
  • Reinforce impersonation awareness: Personnel interacting with Iranian civil-society or diaspora communities should verify the identities of accounts claiming intelligence affiliations before sharing sensitive information.

Physical and Operational Defense

  • Maintain heightened maritime security: Monitor UKMTO advisories and review transit risks in the Strait of Hormuz, waters near Jubail, and the Red Sea off Saudi Arabia.
  • Review Saudi Arabia travel and facility security: Confirm flight availability, maintain alternate travel arrangements, and review shelter procedures amid continued missile and drone activity.
  • Reassess operations near Erbil and regional border crossings: Review proximity to Iranian Kurdish opposition facilities, update emergency plans, and account for disruptions associated with Iraqi and Pakistani border closures.
  • Review security at Western-linked facilities: Organizations associated with US or allied government operations should assess physical security and incident-reporting procedures in light of Iranian statements identifying Western political and infrastructure targets as potential objectives in renewed hostilities.

Strategic Outlook: Operational Forecast

Over the next 48–72 hours, Ansarallah is likely to sustain missile and drone pressure on Saudi cities and infrastructure while continuing operations against Yemeni government forces in Taiz, Shabwa, and Aden. The deployment of RAF Typhoon aircraft strengthens Saudi air defenses but also places additional UK personnel and equipment within range of potential Houthi attacks.

Iran’s maximum border alert, ballistic missile activity, and preparations for communications restrictions indicate heightened readiness for a possible resumption of large-scale hostilities. Israel’s recent long-range strike exercise reinforces concerns about further escalation, although renewed US-Israeli military action remains uncertain. Iranian strikes near Erbil and the closure of Iraqi and Pakistani border crossings also raise the possibility of further disruption to regional security and logistics.

Commercial shipping is likely to remain exposed to attacks in the Strait of Hormuz and surrounding waterways, while competing claims about responsibility will continue complicating incident assessments. In the cyber domain, Handala may release additional material it claims to have obtained from Israeli military sources, and intelligence collection, impersonation activity, and competing information narratives are likely to persist alongside physical threats.

When physical threats manifest in the real world, every minute counts. Whether tasked with Executive Protection, securing critical infrastructure, or monitoring live events, security teams face a constant challenge: turning massive volumes of noisy online chatter into rapid, actionable insight.

For traditional workflows, surfacing relevant situational awareness required complex Boolean query construction, exhaustive lists of regional keywords, and constant tweaking of syntax. But when an operational threat is unfolding, troubleshooting search logic is the least of your priorities.

In a recent live session, Flashpoint’s Alanah Crocker, Head of the Flashpoint Training Academy, demonstrated a major evolution in Flashpoint’s physical security intelligence capabilities: Natural Language Search and AI-driven Search Planning.

Real-World Impact: Minutes Can Save Lives

When it comes to protecting people and infrastructure, security teams need to know what is happening around them. This involves pulling from mainstream social networks, fringe spaces, regional platforms, and illicit chat channels. By layering in geospatial enrichment and analyst-led finished intelligence, organizations gain the insights they need to function in high-stakes environments.

In this live session Flashpoint showed how analysts no longer need to spend time manually building complex syntax trees. Instead, using Flashpoint’s Physical Security Intelligence, analysts can simply describe what they want to discover in plain language.

  • “Recent arson attacks against factories in North America”
  • “Traffic disruptions in Central London near VIP transit routes”
  • “Situational awareness and security chatter around BC Place Stadium”

With this update, analysts no longer need to spend time manually building complex syntax trees. Here’s what an updated workflow looks like using Flashpoint PSI:

  1. Plain Language Prompting: Type your operational question or intelligence focus area into the search bar using everyday language.
  2. Automated Search Plan Generation: Flashpoint Ignite instantly analyzes current online chatter, identifies relevant regional keywords, assigns date parameters, and applies precise geospatial boundaries.
  3. Human-in-the-Loop Review: Review the proposed search plan, tailor keywords, adjust date ranges, or modify the boundary before execution.
  4. Rapid Execution & AI Summarization: Execute the query to receive curated results from global sources alongside an executive summary of key takeaways and sentiment.

How Natural Language Search Accelerates Physical Security Triage and OSINT Workflows

By integrating AI-driven search planning directly into Flashpoint PSI, Flashpoint fundamentally changes how security teams move from initial inquiry to tactical triage. When facing unfamiliar threat vectors, analysts need to eliminate the cold start, so that they are not spending needless time guessing local slangs, hashtags, or regional terms to query. Flashpoint’s natural language processing automates this pre-research phase by synthesizing live open-source chatter to surface active jargon and keywords automatically.

Spatial context is equally seamless. Instead of manually looking up street intersections or plotting coordinates on a map, analysts can simply mention a landmark or venue in plain text. Flashpoint PSI understands the geographical intent, automatically constructing precise spatial geofences around the physical asset, event, or VIP travel routes.

Once populated, intelligence gathering becomes a dynamic conversation rather than a static reporting exercise. Analysts can interrogate their data in real-time, asking Flashpoint to isolate video uploads, filter for explicit threats, or hone in on specific operational themes throughout this workflow—all while ensuring the analyst remains firmly in control throughout the entire workflow.

Data Center Physical Security: Mitigating FPV Drone Threats

In this post, we explore how shifting online sentiment and low-cost First-Person View (FPV) technology are creating an unprecedented airborne threat vector for critical data center infrastructure.

August 10, 2026

Data centers have become a driving force in the modern digital economy—powering cloud services, global enterprise operations, and the explosive growth of artificial intelligence (AI). However, due to growing negative public discourse, data centers are facing a new physical threat vector: low-cost, payload-capable drones.

According to Flashpoint research, shifting public sentiment surrounding AI development, combined with the extreme accessibility of First-Person View (FPV) drone technology, is creating an unprecedented hybrid threat to physical critical infrastructure.

Here is what you need to know about this emerging threat landscape and what it means for physical security teams protecting critical assets.

Growing Online Sentiment and Anti-AI Hostility

Organizations tasked with protecting critical data infrastructure need to understand that this growing threat is not developing in a vacuum. Across both clearnet and Deep and Dark Web (DDW) forums, online discussions regarding data center expansion have intensified, with a significant portion bordering on hostility. Key drivers of negative sentiment include:

  • Environmental & Local Concerns: Debates over massive energy consumption, water usage, noise, and localized quality-of-life impacts.
  • Backlash against AI: Discontent directed at tech companies driving the rapid deployment of AI infrastructure.
  • Perceived Regulatory Inaction: Frustration among activists who feel local and state governments are failing to halt or regulate new construction.

While much of the current online chatter currently revolves around organized protests and aspirational threats, Flashpoint analysts note a troubling uptick in rhetoric targeting corporate tech executives and data center infrastructure.

The Evolving Data Center Threat Landscape

Data centers across the United States are seeing a rapid increase in physical and operational threats. Vandalism and property destruction have become common topics in illicit online spaces when discussing data centers and their impact on everyday life. Flashpoint research highlights two primary force multipliers driving this threat:

DIY Drones & Low Barriers to Entry

Historically, kinetic airborne strikes required specialized equipment and advanced training. Today, that barrier to entry has virtually collapsed. Rapid improvements in drone manufacturing have made payload-capable aircraft extraordinarily accessible. In today’s market, an individual can purchase an off-the-shelf system or assemble a customized drone for under $1,000 USD.

Inspiration for these tactics is also readily available; widespread footage of FPV drones operating in conflict zones like Ukraine has demonstrated to online audiences how easily and effectively low-cost aircrafts can be weaponized. Threat actors view this as a high-yield investment, especially given the capability to deploy multiple drones in quick succession.

Protests as Cover for Physical Operations

Organized protests to stop data center development remain prevalent, and large crowds can easily overwhelm contracted security personnel, diminishing the effectiveness of a response to an aerial threat. A malicious actor could use a protest at a data center as cover to cause physical damage to the facility while security resources are spread thin. For example, on July 19, 2026, activists threw balloons filled with acetic acid at a data center construction site in Amsterdam. In its aftermath, Flashpoint analysts captured individuals online discussing the use of drones to deliver similar payloads.

Regulatory and Defense Measure Challenges

Current federal regulations limit the ability to effectively deter or stop an incoming drone threat because the US Federal Aviation Administration (FAA) classifies drones as aircraft. Therefore, organizations specializing in the physical security of data centers will likely need to increase their operational capabilities and advise companies on potential hardening to deter attacks.

Traditional foot patrols and monitoring perimeter access control points will be insufficient in mitigating overhead threats. The majority of data centers are currently not equipped with the specialized Counter-Unmanned Aircraft Systems (C-UAS) equipment, specialized training, or legal authorization needed to respond effectively to airborne incursions.

Protect Critical Infrastructure Using Flashpoint

Defending against aerial incursions requires moving from reactive security to proactive, intelligence-led physical protection. Physical security teams cannot afford to rely solely on ground-level surveillance when threat actors are leveraging open-source hardware and coordinating online.

Flashpoint Physical Security Intelligence (PSI) equips security teams and executive protection units with real-time visibility into emerging physical threats before they reach your perimeter:

  • Early Warning Indicator Tracking: Monitor chatter across mainstream social platforms, fringe networks, and illicit DDW forums to identify probe attempts or the targeting of specific data center facilities and executives.
  • Geospatial Threat Mapping: Overlay real-time intelligence onto physical assets using customizable geofencing to detect active incidents, protest activity, and drone-related discussions near sensitive sites.
  • Actionable Counter-UAS Insights: Receive finished intelligence and analyst support to benchmark threat actor TTPs (Tactics, Techniques, and Procedures), enabling your organization to harden physical structures and justify operational investments.
