Chainalysis breached by external actor using 'offensive agentic' AI techniques; customer names and emails accessed
Chainalysis, a blockchain analytics firm, disclosed on October 30 that an external actor used "offensive agentic techniques" to gain unauthorized access to undisclosed internal systems and tools. Non-sensitive customer data was accessed, including user IDs, full names, email addresses and organization role labels for users provisioned on the platform. The company says the incident is unrelated to the Binance heist from the previous week and that it is still determining which records for each customer organization were accessed.

- No threat actor attribution was given.
Remediação
