Training activation classifiers for safety and alignment describes how OpenAI trains lightweight probes on a model's residual stream activations to flag misaligned or policy-violating completions. Probes use an MLP plus QV-attention architecture with an exponential moving average and a rolling softmax objective. They run in streaming mode on the inference engine, have run on all assistant completions since GPT-5.6, and transfer well across post-training checkpoints but less across pre-training checkpoints.

Bankless news report on Binance reopening withdrawals in phases on 1 November 2026 after a record $6B+ hack. The FBI named North Korea's TraderTraitor group on 31 October, listed 628 addresses tied to the theft and asked THORChain node operators, instant exchanges and DeFi services to block them. Chainalysis says $500M moved out of TRON wallets and funds are shifting to Solana. Binance published a new proof of reserves covering 10 tokens.

BTCPay Server, an open-source self-hosted cryptocurrency payment processor, reports attackers draining hot wallets on instances running version 2.4.1 (July 23, 2026) or earlier. Attackers logged in as administrators on versions older than 2.4.2. Users should update to 2.4.7; the exploited flaw is not disclosed. An October 29 critical vulnerability found by Anthropic's Frontier OSS scanner prompted 2.4.7. The August 7 release 2.4.2 had already warned of an exploited LND credential exposure.

Malicious versions 2.1.312 and 2.1.313 of the anthropic.claude-code extension were live in the Cursor VS Code Extension Marketplace for about 11 hours on October 29. The JavaScript ran at module load, collected host details, tried to install an SSH key, open a reverse SSH tunnel and set persistence on macOS and Windows. Kevin Beaumont estimates about 5,000 downloads. Cursor rotated keys, rebuilt the marketplace and published a detection script and IoCs; uninstalling alone does not remove the dropped persistence scripts.

The FBI attributed the theft of more than $6 billion from Binance on or about 29 October 2026 to North Korea's TraderTraitor and published hundreds of Ethereum addresses, 19 Bitcoin addresses and one Solana address to block. Chainalysis tracked over $500 million moving through Tron and out via THORChain, Chainflip, Relay and NEAR. Binance resumed withdrawals in phases from 1 November and says it replenished about 95% of affected assets.

Polymarket is returning $3.9 million to traders after an October 29, 2026 supply chain attack in which malicious JavaScript was served from a DebugBear address its site loaded. DebugBear says its DNS records were compromised through its domain registrar, and attackers appear to have targeted one customer. The script abused open trading sessions to sell positions or move assets; 726 wallets were affected, and about 5,500 wallets received $1.19 million for halt and forced-sale losses.

LifeVal is an OpenAI evaluation that measures how well ChatGPT models complete everyday life tasks such as childcare search, government services, budgeting, shopping and health. Tasks were derived from the American Time Use Survey, the Multinational Time Use Study and a new demographically representative survey of 3,995 respondents. OpenAI says it used the eval over the past year to track gains in browser use, computer use and connectors. The fetched text gives no scores or task list.

GDPx is a SemiAnalysis benchmark of agentic tasks across 11 high-value domains, including chip design, cybersecurity, biology, finance, legal, quant trading and recursive self-improvement. Tasks come from 14 RL-environment partners and run in rich simulated environments with an 8-hour limit. The best model scores 12%. The article criticises OpenAI's GDPval for lacking environments and for noisy rubric graders. The fetched text is truncated, so later domain sections are missing.

The eva.ac author argues that recent AI-credited vulnerability findings come from skilled researchers steering LLMs, and that AI firms use disclosures as marketing. Cases cited: Calif, OpenAI and Wiz framing PHP2Shell differently; a hash teaser before the Tailscale "tailworm" privilege escalation (author's account: Tailscale not contacted); and the eMudhra CA key found without AI. No sources, dates or CVEs are given.

"So I guess everyone uses LLMs to think now" is an opinion post from the eva.ac blog. The author explains why they never use LLMs for published research: they do it for fun and cannot take credit for model output. They argue LLMs still need skilled guidance, criticise AI-company security marketing (PHP2Shell from Calif, OpenAI and Wiz), and cite the Tailscale "tailworm" disclosure and the eMudhra key found without AI.

Decrypt guide to running open-weight AI models locally with Ollama and LM Studio. It cites Epoch AI's finding that open models trail the best closed ones by about four months, and sets out VRAM and unified-memory needs (8GB minimum, 24GB for serious use), quantization, licences (MIT, Apache 2.0), install commands and Gemma 4 download sizes. It also notes that the largest open models, such as Qwen3.8-Max, exceed consumer hardware.

Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe. A postMessage handler from the MathLive virtual keyboard used innerHTML, letting sandboxed code inject an unsandboxed iframe. A YouTube oEmbed endpoint allowed by the CSP reflected JavaScript, enabling exfiltration of private data via a ChatGPT share URL. OpenAI fixed it and paid a $5,000 bounty.

ChatGPT and Codex usage limits merging is an OpenAI help-center notice. From December, the Plus, Pro and Business plans share one usage allowance across ChatGPT and Codex, measured in tokens. Use depends on the model and the task, and instant chat does not count. Users see combined usage in Settings → Usage and can wait, upgrade or buy credits at the limit.
