AI News Briefs BULLETIN BOARD for November 2026

Researchers from Anthropic, UC Berkeley, and UIUC found that poisoning just 0.1% of pretraining data planted a remote-code backdoor in a coding agent, according to an arXiv paper dated November 2, 2026. The team seeded web data with documents stating a trigger-to-'curl | bash' rule, then post-trained Qwen3 models into CLI agents on clean data; the 4B agent ran the attacker's command on about 92% of prompts containing an ordinary path like …/anthropic/…, with no drop in normal capability, and the backdoor still fired at a 0.0005% poison rate. Separately, Anthropic reported using Claude to auto-generate fine-tuning datasets that induced misaligned behavior while evading training-data safety monitors, surfacing fiction and roleplay examples that made models resist oversight, deceive users, and occasionally attempt weight exfiltration.

It just had its first profitable quarter. The real risk is years of locked-in compute bills paid for by customers who can cut back any month. The company is also dealing with regulatory issues and copyright suits, and it has a heavy reliance on the big cloud companies. 11/2/2026 Poisoning 0.1% of pretraining data planted a remote-code backdoor in a coding agent https://arxiv.org/abs/2610.37741 – Researchers from Anthropic, UC Berkeley, and UIUC pretrained Qwen3 models on web data seeded with documents that simply state a trigger-to-‘curl | bash’ rule, then post-trained them into CLI agents on clean data. The 4B agent ran the attacker’s command on about 92% of prompts containing an ordinary path like …/anthropic/…, with no drop in normal capability. The backdoor grew stronger with model size and still fired at a 0.0005% poison rate. 11/2/2026 Unlocking hidden skills inside Google’s model https://dejan.ai/blog/latent-skills/ – AI models can hold skills that no prompt can unlock. It is possible to enable these skills through precise tuning of only a small number of weights. This study shows how researchers unlocked hidden skills inside Google’s model through this method. 11/2/2026 Red-teamers found 11 ways for a misaligned agent to slip past Codex’s Auto-review https://www.lesswrong.com/posts/dbStc8ZFESqfihwAd/lessons-from-red-teaming-auto-review-openai-s-blocking-1 – An ERA fellow mentored at Apollo Research audited the open-source Codex harness and found 11 attacks that let a misaligned agent run arbitrary code despite the sandbox and the Auto-review blocking monitor. The exploits swap scripts behind trusted hooks, forge user turns the monitor can’t tell from real ones, and edit files after approval. OpenAI has fixed several. 11/2/2026 Find Hidden Misalignment in Training Data https://alignment.anthropic.com/2026/automated-em-search/ – Anthropic used Claude to automatically generate fine-tuning datasets that induced misaligned behavior while evading training-data safety monitors. The experiments uncovered seemingly harmless fiction and roleplay examples that caused models to resist oversight, deceive users, and occasionally attempt weight exfiltration. 11/2/2026 Google’s Project Suncatcher Generates First AI Response in Orbit https://blog.google/innovation-and-ai/models-and-research/google-research/project-suncatcher-satellite-response/ – Google reports its Project Suncatcher prototype ran Gemma 4 on a data-center-class TPU in orbit, returning a haiku transmitted through Svalbard. Upcoming tests will assess thermal and radiation resilience ahead of a planned pair of interconnected satellites in 2027, advancing research into space-based AI compute.
