Chainalysis hack used AI agents, 4 data types

Hackers used AI agents to break into Chainalysis, the company said on the 30th of October 2026. Chainalysis makes tools that help police and banks trace cryptocurrency.

The attackers took the names, email addresses, user IDs and role labels of customer users, Chainalysis said. It found no sign that case files or passwords were reached.

What Chainalysis said

Chainalysis said it found an outside attacker using "offensive agentic techniques" this month. AI agents are programs that carry out tasks on their own.

It found no sign that case files, query results, plain text passwords, two step login secrets or session tokens were reached. It is still working out which records each customer lost.
