What happened

Between 10 and 13 November 2025, the latest phase of Operation Endgame was coordinated from Europol's headquarters in The Hague. The actions targeted one of the biggest infostealer Rhadamanthys, the Remote Access Trojan VenomRAT, and the botnet Elysium, all of which played a key role in international cybercrime. Authorities took down these three large cybercrime enablers and provided 2 million impacted email addresses and 7.4 million passwords to HIBP.

What was exposed

  • Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
  • Passwords: The secret you use to sign in, stored by the breached service either in plain text, in a scrambled form called a hash, or encrypted. How it was stored decides how quickly it can be recovered.
