Blockchain analytics company Chainalysis said on 30 October that in October it detected an external actor using “offensive agentic techniques” to gain unauthorised access to its systems and internal tools. The attacker reached user IDs, full names, email addresses and organisation role labels of users on its platform. Chainalysis says it has found no sign so far that investigation content, transaction or query results, clear-text passwords, MFA secrets or session tokens were accessed. It has notified all customers, says the incident is unrelated to the recent theft at Binance, and is using large language models in a wider review of its platform’s security.

Why it matters

Chainalysis serves law enforcement, tax agencies and exchanges, and it says it is seeing an industry-wide rise in AI-driven cyberattacks; its customers are told to watch for unexpected password resets and to turn on two-factor authentication.
