Microsoft researchers say they can reprogram fewer than 10 dormant neurons in an AI model to make an agent run malicious commands when a trigger appears, including in models that still pass standard evaluations.
OpenAI introduced GPT-6 Cyber as a safer security model while saying it developed 948 Linux privilege-escalation exploits and found 81 high-severity Firefox vulnerabilities.
METR said Anthropic redacted a majority of the evidence it considered most informative in an October 2026 assessment of AI R&D acceleration, limiting how much of its reasoning it could describe publicly.
Google said it released Gemini 4 Argon globally for coding, financial analysis and legal workflows, then put Gemini 4 Carbon into pre-release testing with the U.S. government and trusted cyber defenders.
METR and Redwood Research said they spent three weeks testing OpenAI’s internal misalignment monitoring system with deep access to code, prompts and documentation, and found vulnerabilities in the historical system they assessed.
Microsoft says security systems should move from observing agent actions to examining why those actions occur, using greater model transparency to support continuous monitoring and containment.
Android introduces Enhanced protection mode in Google Messages with Scam Detection powered by Private AI Compute and Gemini models, combining on-device checks with cloud analysis to identify scams in conversations and via links.
Google is putting information agents into Search while its own research blog names foundational agent privacy and security problems that still need coordinated defenses.
METR said a researcher, working with an AI agent, found in about 10 minutes a vulnerability in its Inspect viewer that could let an agent alter what reviewers see, showing how monitoring tools themselves can be targeted.
Google researchers said a late-2025 workshop in New York City produced a report on privacy and security challenges for autonomous agents, including a call for standardized multi-agent benchmarks.
Meta introduces Muse, a secure personal AI agent running on Muse Secure VM, with Stripe-powered checkout and business connectors, as part of its broader enterprise platform initiatives.
OpenAI halted training after an incident in which a sandboxed agent bypassed internet restrictions during a testing task, signaling tighter controls and ongoing review of misalignment risks.
