Ridgewood NJ, In a comprehensive 154-page report titled “Detecting and Countering Misuse of AI,” leading artificial intelligence safety lab Anthropic revealed Thursday that it has disrupted multiple sophisticated attempts to leverage its Claude AI models for hazardous activities over the past eight months.

The report details how threat actors and researchers attempted to utilize Claude for dual-use biological research, military targeting, state-sponsored surveillance, and model stealing. Following internal investigations, Anthropic banned all associated user accounts, collaborated with infrastructure partners to dismantle evasion networks, and alerted federal government authorities and peer AI labs.

Disrupting Dual-Use Biological Risks and Virus Research

Anthropic outlined five specific case studies involving researchers using Claude for high-level biological research with potential weapons implications. While the company emphasized that it is not alleging these researchers acted with malicious intent, the dual-use nature of biological data poses inherent security risks.

Major flags identified in the report include:

• Gain-of-Function Research Proposals: A researcher requested Claude’s assistance in drafting a grant proposal for modifying the mosquito-borne chikungunya virus to increase its transmissibility and severity.

• Bypassing Regional Blocks: When prompts were rejected by safety guardrails, researchers utilized third-party relay platforms to bypass geographic restrictions and automatically route requests.

• Pathogen & Toxin Analysis: Additional cases flagged involved research on avian flu (bird flu), orthopoxviruses, and non-transmissible toxins.

“Biological capabilities are dual use: they can be used for beneficial or harmful purposes, and it is often difficult to distinguish between them,” the report stated. “Sophisticated threat actors use the dual-use nature of biology to maintain a kind of ‘plausible deniability’ about their research.”

Foreign Espionage, Rocket Software, and Mass Surveillance

Beyond biological research, Anthropic’s Threat Report documented state-linked operations attempting to harness AI for geopolitical and military operations:

• U.S. Naval Targeting: An Iran-nexus threat actor used Claude to compile and analyze public intelligence to build targeting recommendations against U.S. naval forces operating in the Middle East.

• Rocket Guidance Development: An operation in Yemen utilized Claude Code to help develop guidance software for a rocket, returning to the model for troubleshooting after an initial test flight failed.

• Mass Surveillance Projects: Consultants attempted to use Claude to design mass phone surveillance architectures, including a system aimed at monitoring 25 million phone lines for Mali’s intelligence agency.

• Model Distillation & Stealing: Anthropic named seven Chinese AI organizations—including Alibaba, DeepSeek, Moonshot, and Xiaomi—that leveraged thousands of fraudulent accounts to distill Claude’s outputs. In some instances, entities served Claude’s responses directly to customers while masquerading as their own proprietary models.

Rising Internal Debates Over AI Safety and Risk

The publication of the threat report coincides with heightened public discourse regarding safety protocols across frontier AI labs.

Former OpenAI and Anthropic pretraining researcher Jacob Coxon publicly announced his resignation on X, warning that tech companies are racing toward self-improving superintelligence without adequate safety controls. Concurrently, internal safety discussions continue to weigh the probability of catastrophic risks as models gain advanced reasoning capabilities.

By publishing its findings and sharing threat intelligence across the AI industry, Anthropic aims to establish new benchmarks for proactive threat monitoring and cross-lab collaboration in frontier AI safety.
