Chainalysis says hacker using ‘offensive agentic techniques’ accessed its customers’ names and emails

Chainalysis reported on October 30 that an external actor used what it described as offensive agentic techniques to gain unauthorized access to some of its systems and internal tools. The company stated that the incident involved AI agents performing coordinated multi-step actions against its infrastructure rather than a single exploit.

The unauthorized access reached a limited set of non-sensitive customer data, which included user identifiers, full names, email addresses, and role labels within customer organizations. Chainalysis reported finding no evidence that authentication credentials, session tokens, or the content of investigations were accessed. The company has notified customers and is working with external cybersecurity experts to patch vulnerabilities and harden its systems.

The Block noted that the firm is also tracking a separate multibillion-dollar hack involving Binance, where attackers are reportedly using a Tron protocol to avoid stablecoin freezes.
