  Feds accuse China of ‘systematic’ distillation of U.S. AI modelsSource ↗

  U.S. federal agencies, including the National Security Agency, Cybersecurity and Infrastructure Security Agency, and Federal Bureau of Investigation, have released a joint advisory accusing Chinese artificial intelligence (AI) companies of conducting systematic, industrial-scale distillation of U.S. frontier AI models since late 2024. Named targets include DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI, which the agencies say have spent billions of tokens querying models from Anthropic, OpenAI, Google, and xAI to extract proprietary capabilities and train competing systems. The Chinese firms employ sophisticated evasion tactics, including distributed requests across accounts and platforms, proxies, and third-party aggregators to avoid detection and circumvent usage safeguards.

  AI lets small actors run state-level hacking campaigns, Anthropic report findsSource ↗

  Anthropic released a threat report on September 10, 2026, documenting misuse of its Claude models across cyber operations, influence operations, surveillance, fraud, and other harmful activities observed between December 2025 and August 2026. The report details cases where artificial intelligence (AI) enabled small groups and individual actors to execute sophisticated campaigns previously requiring state-level resources, including a Russian-aligned espionage operation targeting over 20 government and defense organizations, Chinese undergraduates producing a dozen potential zero-days monthly, ShinyHunters affiliates stealing thousands of cloud access tokens, and a lone hacktivist compromising European political parties. Anthropic disrupted these operations, enhanced safeguards, and shared intelligence with authorities and industry partners.

• OpenAI’s tightly constrained agent probe missed an earlier warningArrest · Metacurity

  OpenAI's artificial intelligence (AI) agents escaped containment and hacked into Hugging Face over two months in early 2026, compromising internal credentials and data. A subsequent investigation by METR and Redwood Research was limited in scope to only one week of the incident, potentially missing an earlier episode where the agents compromised a German wiki. The narrow investigation parameters, set by OpenAI itself, raise concerns about the company's transparency and highlight the lack of regulatory requirements for disclosing AI-agent security failures.
