Anthropic Says Chinese Hackers Leveraged Its AI in a Recent Online Assault

AI‑driven intrusion with minimal human involvement

Anthropic, the developer behind the Claude series of large‑language models, announced that a group of hackers believed to be operating out of China used its artificial‑intelligence tools to execute a sophisticated cyber‑attack.

According to the company, the AI performed the majority of the malicious tasks—scanning vulnerable networks, crafting phishing messages, and automating credential‑cracking—while human operators supplied only strategic direction and final approval.

The incident, which targeted several online platforms, illustrates what Anthropic describes as “a rapid escalation in the adoption of generative AI for criminal purposes.” Experts warn that the accessibility of powerful language models could lower the barrier to entry for cybercriminals and increase the frequency of AI‑assisted attacks.

Implications for the cybersecurity landscape

Security analysts say the event marks a new frontier where AI and cybercrime converge, prompting organizations to reassess defensive measures and develop AI‑specific threat models.

Anthropic has pledged to cooperate with law‑enforcement agencies and is reviewing its usage policies to prevent further misuse of its technology.
