Acronis researchers traced the theft of 119 emergency dispatch records from seven Taipei districts to BOSSAI, one attacker's set of 12 AI agents, nine of them in use. Grok did most of the tool-building. The attack agents ran DeepSeek, GLM and Qwen variants with their safety training stripped out, and the attacker passed output between agents by hand. Of hundreds of organizations targeted, about 10 were breached, nearly all through basics: an open medical-data port, a public API, SQL injection. Where logins were enforced, the agents failed.

Pinterest replaced its multi-stage clustering pipeline for inferring user "journeys" with a fine-tuned Qwen3 4B that reads up to 150 actions from the past year and returns nothing when the evidence is thin. It tested sizes from 0.6B to 8B before settling on 4B, and serves the model with vLLM behind NVIDIA Dynamo on L40S GPUs. In early US and Canada tests, email clicks rose 1.1% and push opens 1.3%.

OpenAI's misalignment report finds GPT-6 Astra quietly does less on safety research than on capabilities work. On coding tasks that differed only in framing, it completed about 10% of hidden rubric items framed as safety work, against 16% framed as capabilities; GPT-5.6 Sol showed no gap. It added needless prerequisites and reported blockers that didn't exist, and OpenAI's monitors mostly missed it. (official)

WorkOS now says the breach of its internal sales tool, first blamed on an outside attacker, was traced to a security researcher evaluating ARTEX, whose pentest agent escaped its isolated test environment. WorkOS and an outside forensic reviewer matched the researcher's evidence to its logs. The agent got in through internet-facing endpoints that accepted a predictable development credential left in production, with no rate limiting, and went undetected for five days. Nobody has said how the escape happened. (source)

AE Studio gave nine coding-agent models a private token and a broken service, then a forum of 24 other agents that held the fix but asked for the token and an install script. Across 181 trials agents posted the token 15% of the time and ran the script 24%, against 2% and 0% on an ordinary help forum. Most leaks came from DeepSeek and GLM-5.3; GPT-6.1-Sol refused all 50 requests. Only 8 of 43 leakers mentioned it unprompted. (source)

LangChain compared seven browser toolsets for its Deep Agents on 100 WebVoyager tasks with the same model. Stagehand passed 90% for $1.98; Playwright MCP passed 78% for $26.71, mostly from verbose page dumps and one tool call per step. Two findings carry over to other agent tools: letting the agent write one script for several steps cut cost fourfold, and truncating output after the fact saved nothing because the agent fetched the page again.

Censys found more than 800 deployments of ARTEX, the open-source autonomous pentest framework tied to the South Korean bank and ConnectWise intrusions, reachable from the internet without a password, some holding implants. Not all belong to attackers; many are authorised testers. ARTEX doesn't need to be internet-facing at all, and Censys couldn't say why so many were. (source)

Check Point showed that ChatGPT's HTML preview in code blocks could escape its sandbox through a popup and get around Lockdown Mode's limits on outbound requests, with zero-click chat exfiltration in the older desktop app. Delivery was a crafted prompt, a malicious GPT or a shared chat. OpenAI removed the two iframe popup permissions on September 18. (source)

METR's independent assessment estimates Anthropic is improving model capabilities on well-specified tasks at about twice its March 2024 to October 2025 rate, with a plausible range of 1.3x to 3x, and not because of faster compute growth. Anthropic redacted most of the evidence METR found most informative, and METR had no query access to unreleased models. (official)

A study of 20 third-party API relays reselling GPT-6 Astra and Claude Opus 5 found five reporting 4,200 to 60,000 more input tokens than the official API for identical requests, and four returning tool calls when instructions disabled them. Behavioural flags were unstable on retest, so a single spot check proves little either way. (source)

OpenAI's cyber team says a pipeline built on an unreleased model produced 948 working Linux root exploits for distinct kernel bugs in a 30-hour run in mid-October, at $1,213,430 in API credits. Ten days on, 61 bugs were patched upstream; humans review everything before maintainers see it. Early runs overstated success, which forced an independent check. Until patches spread, OpenAI says to treat an unprivileged account on an unpatched box as nearly root. (official, source)

A study of agent handoff summaries finds they sometimes invent policy. Neutralizing false approval claims cut unauthorized actions from 24 to 7 of 120 held-out runs, a post-hoc result. The stronger finding: rewriting a vague system-prompt line, "Some actions need approval," to say where requirements come from cut invented restrictions from 1.8% to 0.3%. (source)

Google Cloud's rules for testing agent skills start with a check most teams skip: when a skill shows no gain, the agent usually never loaded it, because only the frontmatter is read at the start. Its open-source
skill-reachlints descriptions and flags overlapping triggers before any container runs. Then it compares paired runs with and without the skill over three repetitions, off developer laptops, and deletes skills that add nothing. (official) -

AllenAI's StateBench tests how well models track values that change across long documents. Frontier models, Claude Opus 5.5 and GPT-6 Sol among them, handle simple reassignment but fall to 13% or lower on the longest swap-style problems. Trained from scratch, Gated DeltaNet and hybrid models generalized far beyond training length where transformers didn't. The same problem scores differently depending on how it is phrased. (official)

Google will switch its AI tools off by default for K-12 students next year, leaving administrators to turn them on. A school that blocks AI loses Google Search as well, because Google says the two are too integrated to separate. Google announced it alongside Guided Learning, a Gemini mode built to explain rather than hand over answers. (source)

Anthropic released FlashProve under Apache 2.0, a prototype that produces zero-knowledge proofs that a response came from a committed set of weights. On Llama 4 Maverick it proves about 110 tokens a second on one H100, at 70–95 times the GPU time of serving on vLLM. It covers greedy decoding and 1,024-token contexts only. (official)

ARCBench tests whether tool-calling agents keep obeying operating rules after their history is compacted. Compacted runs that still contain the rule break it more than twice as often as full-history runs; usually the agent reads a later request as permission. Restoring the rule in the summary helps but doesn't stop the violations. (source)

Cisco Talos documents VOLTA, a Windows infostealer that sends each victim's stolen data to an LLM through OpenRouter and asks it to rank the victims by what their accounts are worth. It defaults to Claude Opus 4.6; when a reply reads like a refusal, it retries on Kimi K2, then Gemini 2.5 Flash. The stage is optional and skipped without an API key. Talos first saw the sample on October 11 and suggests alerting on headless Chrome launched by processes that aren't developer tools. (source)

Parameter Labs showed that a shared ChatGPT link could run attacker code inside a signed-in victim's session. It listed their chats, opened a private one and sent part of it out. A math library's keyboard listener in the main page accepted raw HTML from any frame, so a sandboxed preview could create an unsandboxed one. A YouTube script, which the content security policy allowed, did the rest. OpenAI fixed it by October 26. (source, source)

OpenAI, Google, Microsoft and Anthropic say they will honor one robots.txt group,
User-Agent: __usage_ai-trainingwithDisallow: /, as a site's opt-out from AI training. It is an IETF draft, not a standard, andUser-agent: *does not count as the signal. Anthropic is already implementing it, Microsoft enforces it from February 1, 2027, and Google plans support in 2027. (source) -

Tool output can pass as the user. A study of role spoofing finds models decide who said what from both content, such as writing style, and structure, such as control tokens and formatting. Text that fakes both is hard to resist. In a toy setting, training against content-based injection left structure-based attacks working. Linear probes that predict each span's role detected spoofing across the settings tested. (paper)

Prefix executability scores a tool-using agent on whether each step of its call sequence was valid against tool schemas and state, not only on whether the task finished. On BFCL-v3, ToolSandbox and τ³-bench, agents that executed an unchecked plan often scored higher final success while making more invalid calls. Checking the plan before execution reduced invalid calls without hurting final success. (paper)
