🐞 Nessus Agent Vulnerability on Windows Enables Arbitrary Code Execution
Source: https://t.co/6gnqn918jC
A newly disclosed security vulnerability in Tenable's Nessus Agent for Windows could allow attackers to execute malicious code with the highest level of system privileges, raising serious concerns for enterprise security teams relying on the widely-deployed vulnerability assessment platform.
The flaw enables a threat actor to create a Windows junction, a type of filesystem symbolic link that can be leveraged to delete arbitrary files with SYSTEM-level privileges.
Once file deletion at that privilege tier is achieved, the condition can cascade into a full arbitrary code execution scenario, effectively granting an attacker complete control over the affected machine.

An update from NIST. Due to volume they’re only going to enrich CVEs that are meaningful to USG federal systems and critical software (some more nuance in the blog post). This means if you’re relying on the NVD data for your enterprise security program and use other software, your tools may not flag software you use as at risk. https://t.co/pI2o2XootK
If you still have doubts about Claude Mythos, here's what it did already:
> Found a 27-year-old OpenBSD bug in one of the most security-hardened operating systems on earth for <$50
> Broke into a production virtual machine monitor (basically the tech that keeps cloud workloads from seeing each other's data)
> Turned Firefox vulnerabilities into working exploits 181 times
> Found a 16-year-old FFmpeg bug that survived every fuzzer, every code audit, and every human reviewer since 2010
> Wrote a FreeBSD exploit that gives any unauthenticated attacker on the internet full root access. No human was involved after the first prompt.
> Chained 4 separate vulnerabilities together to build a browser exploit that escaped both the renderer and the OS sandbox
> Found critical holes in every major web browser and every major operating system
> Gave Anthropic engineers with zero security training a complete and working exploit by morning
> Cracked cryptography libraries protecting TLS, AES-GCM, and SSH
Amazon had four Sev-1 outages (their highest severity level) in a single week. Internal memos say AI-assisted code changes were a contributing factor.
The timeline here is wild. In October 2025, Amazon laid off 14,000 corporate employees. In January 2026, another 16,000. That’s about 30,000 people in five months, roughly 10% of the corporate workforce. CEO Andy Jassy said the cuts were about culture, not AI.
During those same months, Amazon set a target: 80% of developers using AI coding tools at least once a week. They tracked adoption closely and blocked rival tools like OpenAI’s Codex. Even so, 30% of developers still hadn’t touched Amazon’s in-house tool Kiro by January.
In December 2025, Kiro caused a 13-hour AWS outage. The AI tool had production-level permissions and decided the best fix for a bug was to delete and recreate an entire live environment. A second incident involved Amazon Q Developer, another AI tool. Amazon blamed both on “user error, not AI.” But quietly added mandatory peer review for all production access afterward.
Then March 5: Amazon’s retail site went down for about six hours. Over 22,000 users reported checkout failures, missing prices, and app crashes. Amazon called it a “software code deployment” error.
Five days later, SVP Dave Treadwell made the normally optional weekly engineering meeting mandatory. His memo acknowledged “GenAI tools supplementing or accelerating production change instructions, leading to unsafe practices.” These problems trace back to Q3 2025. Amazon’s own assessment: their GenAI safeguards “are not yet fully established.”
The new rule: junior and mid-level engineers now need senior sign-off on any AI-assisted production changes. Treadwell also announced “controlled friction” for the most critical parts of the retail experience.
For context, Google’s 2025 DORA report found 90% of developers use AI for coding but only 24% trust it “a lot.” An Uplevel study of 800 developers found Copilot users introduced 41% more bugs with no improvement in output. Amazon is finding out what those numbers look like at the scale of a $500 Billion revenue company, with 30,000 fewer people on staff to catch the mistakes.
