Operation Endgame Data Breach

What happened

In May 2024, a coalition of international law enforcement agencies took down a series of botnets in a campaign they coined "Operation Endgame". Data seized in the operation included impacted email addresses and passwords which were provided to HIBP to help victims learn of their exposure.

Exposed data

Recommended actions

• Change your Operation Endgame password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Operation Endgame — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
