Chainalysis said it began restoring KYT and Address Screening access in phases on November 6 after a cyberattack disrupted its services. Customers must reset passwords, rotate API keys and submit trusted IP addresses for an allowlist before resuming use.

The company said it was validating enhanced security controls during the rollout. Reactor and Data Solutions remain offline. Chainalysis has said names, usernames, password hashes and live tokens for all users were exposed, while reporting no evidence that attackers accessed investigations data.
