What to do
- This is only a claim by the attackers so far. Do not panic, but do the basics:
- If you have an account, change that password, and anywhere you reused it.
- Turn on two-factor authentication, ideally an authenticator app or passkey, not SMS.
- Treat this as unverified. Ask the organisation directly before acting on it.
- If this is a vendor of yours, ask what of your data they held and whether it was in scope.
- Reset any API keys, SSO trusts or shared credentials you have with them.
Not sure? Ask an assistant with the sources attached, or have a coding agent check your systems.
