In November 2026, Europol and international law enforcement partners dismantled infrastructure supporting several malware operations. Among them was CastleRAT, a remote access trojan (RAT) that enabled criminals to remotely control infected computers. Europol provided HIBP with 180k email addresses associated with CastleRAT infections, along with 893k unique passwords observed more than 3M times across accounts used on infected computers. The passwords are now searchable via Pwned Passwords.
