Operation Endgame 2.0
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.

Breach Classification
HIBP enables you to discover if your account was exposed in most of the data breaches by directly searching the system. However, certain breaches are particularly sensitive in that someone's presence in the breach may adversely impact them if others are able to find that they were a member of the site.
A sensitive data breach can only be searched by the verified owner of the email address being searched for. This is done via the notification system which involves sending a verification email to the address with a unique link.
There are presently 74 sensitive breaches in the system including Adult FriendFinder, Ashley Madison, and others.
