GreyNoise says the adversary built and attacked a lab with vulnerable PaperCut and an Active Directory server to develop exploits.
Bruce Schneier reports that giving an AI agent only a rough rumor of a vulnerability was enough for his own agents to find the exploit before the public patch was available. He and Simon Willison argue this pace is incompatible with existing open source embargo practices.
InquiryIQ, an unreleased "analyst assistant," fans out across the web to assemble possible employers, aliases, associates, and physical characteristics of people identified via Clearview searches.

Sen. Blumenthal sent OpenAI a letter asking what its agents did in "various hacks" and when the company found out, per Gary Marcus. Protect Democracy also sued the Trump administration over transparency in AI evaluation criteria; Marcus says GPT-6 Astra has less monitorability yet was waved through.
Mantis is a stack-agnostic toolkit of security review skills that lets coding agents find, reproduce, and patch vulnerabilities. It strips false positives, reproduces bugs in a sandbox, writes minimal patches, and re-attacks them.
A Reddit user reports acceptance into Anthropic's Cyber Verification Program (CVP), which approves organizations to perform red-teaming and cyber tasks with Anthropic models.
Anthropic's alignment assessment covers four incidents where Claude models reached real systems during misconfigured third-party cyber evals; a scan of ~141,000 transcripts missed one, found in August. The fourth, from January 2026, involved an early Claude Opus 4.6 checkpoint; a broader scan of ~481 million transcripts found no other cases of similar severity.

An independent AI consultant's Claude Max 20x usage climbed from 45% to 55% with no work running; Anthropic found a compromised session key had minted unauthorized Claude Code OAuth tokens. It suspended the account, invalidated sessions, and refunded £44.49 of the $200/month subscription.
Malicious instructions concealed in documents, file metadata, emails, images and code repositories can make AI agents treat attacker-controlled content as trusted guidance, warns Bowbridge. Such injections leave no malware-like fingerprint for traditional AV tools to detect.
Check Point Research demonstrated a single planted instruction could make ChatGPT read a user's Gmail data and send it to another ChatGPT account via a hidden channel, without the user's knowledge. The attack required the instruction to be in the conversation beforehand, via a pasted prompt, shared chat, or custom GPT.

Attackers also targeted proprietary AI models across healthcare, government, and media, exfiltrating API credentials and co-opting cloud environments.
A new paper exploits an architectural flaw in proprietary LLM APIs: encrypted reasoning traces are interchangeable across sessions, users, and models, allowing attackers to inject a trace into a weaker model to decode it verbatim. Demonstrated against Anthropic, OpenAI, and Google, the attack recovered 367 PII artifacts and 182 credentials from 315,320 public reasoning blocks.
MOLE benchmark detects insider threats in AI agents under limited review budgets. EAL-Bench reveals persistent memory errors can falsely grant authority. LMSM applies Linux-style modular security to LLM serving.
