Chainalysis Confirms Data Breach Exposed User Credentials and Active Tokens

Chainalysis, one of the most widely used blockchain analytics providers, has confirmed that attackers gained access to user data during a security breach. The company said exposed information included password hashes and live authentication tokens, raising concerns about potential unauthorized account access.
