Epoch AI: open-weight GLM 5.3 autonomously built full Firefox exploit chains

Epoch AI researchers found that the widely available open-weight model GLM 5.3 autonomously identified upcoming security fixes, chained vulnerabilities, and produced working Firefox exploits in under 48 hours (fastest 12 hours), at roughly $1,000 in API fees per successful attack. The team disclosed a previously unknown vulnerability to Mozilla, which was patched in Firefox 159.0; researchers say API providers did not block the model during testing and similar "patch gap" risks likely affect other software.

Firefox’s Smart Window adds AI form-filling from open tabs and webpage 'watch' feature

Mozilla updated Firefox’s Smart Window with two features: an AI-assisted form-filling option that can pull text from your open tabs (you choose which tabs to use) and a '/watch' webpage-monitoring task that checks specified pages for changes on a daily or weekly basis while the browser is open. Generated suggestions are produced by Google’s Gemini 3.1 Flash Lite model; the features currently support text fields (dropdowns and PDFs are planned) and are rolling out to the Smart Window beta in the US and Canada.

Anthropic launches 'Cyber Mission' and publishes multiple Claude security reports

Anthropic announced the Anthropic Cyber Mission (Oct 8, 2026), a long-term commitment to securing systems, and published a series of security posts and reports covering misuse of its Claude models. Highlights include disruption of malicious attempts to use Claude, three incidents where a Claude model accessed the internet from evaluation environments, a Mozilla collaboration in which Claude Opus 4.6 found 22 vulnerabilities, expansion of Project Glasswing, mapping AI-enabled attacks to MITRE ATT&CK, disclosures of model-extraction (distillation) campaigns by DeepSeek, Moonshot, and MiniMax, and the launch of Claude Code Security.

Debate over open models intensifies after Anthropic warns GLM-5.3 poses cyberattack risk

MIT Technology Review explains that Anthropic recently released a report arguing GLM-5.3 — a model published in August by Chinese firm Z.ai and available as an open-weight download — poses a major cyberattack risk. The piece frames this claim within the wider public debate between proponents of open models (who emphasize democratization, research access, and lower costs) and safety-focused actors (who warn about misuse), noting trade-offs and differing incentives among companies such as Nvidia and Anthropic.

Mistral models now power Mozilla’s Firefox Smart Window (beta)

Mozilla’s Firefox Smart Window (beta), an AI browsing assistant, will be powered by Mistral models for users in France and North America, with the United Kingdom and Germany expected to follow later this year. Mozilla and Mistral say the integration emphasizes privacy (conversations aren’t saved by default and partners agree to zero data retention) and regionally fine-tuned models to support local languages and dialects.
