confirmed an attacker used "offensive agentic techniques" to access its systems and internal tools, exposing user IDs, full names, work email addresses and organisation role labels. It detected the intrusion in October, says investigation graphs, notes, cases, query results, clear-text passwords, MFA secrets and session tokens show no sign of access, and has not disclosed the entry point, vulnerabilities, attacker or total number of affected users.

What to do

  1. Enable two-factor authentication on accounts where it is not already active.
  2. Watch for unexpected password reset requests and authentication prompts.
  3. Be cautious of messages to staff that use names, work email addresses or role details, as these could be used in targeted phishing.
  4. Await the organisation-specific record breakdown from Chainalysis to confirm which of your records were accessed.
