### After the Endgame takedown: check your domains in HIBP and Shadowserver, rotate anything stealer-exposed, and check WordPress sites for Gootloader

- **Credentials:** watch HaveIBeenPwned domain search and Shadowserver reports for your domains; for any hit, reset the password, revoke sessions and tokens, and check the device it came from for an infostealer, since StealC/CastleRAT take cookies and saved logins too.
- **WordPress owners:** Europol urges updating credentials, enabling MFA and patching; Gootloader injects pages offering fake legal documents (agreements, contracts) on hacked sites.
- **Endpoints:** users who downloaded a 'legal agreement' ZIP from a search result are the classic Gootloader path; review proxy logs for such downloads.
