Operation Endgame 2.0 data breach

15,436,844 accounts · breached May 23, 2025

This data was gathered by malware running on victims' devices, not taken from one company's servers.

What happened

In May 2025, a coalition of law enforcement agencies took down the criminal infrastructure behind the malware used to launch ransomware attacks in a new phase of "Operation Endgame". This followed the first Operation Endgame exercise a year earlier, with the latest action resulting in 15.3M victim email addresses being provided to HIBP by law enforcement. A further 43.8M victim passwords were also provided for HIBP's Pwned Passwords service.

What data leaked

  • Email addresses
  • Passwords

What to do if you had an account

  1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
  2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
  3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
