Platform incident contacts

Draft: pending legal review.

If an account on a platform you use may be compromised, start with the platform\u2019s own pages below. Export logs early: platforms keep them for limited periods that depend on your plan and can change, so check the current documentation.

If your platform isn't listed: isolate the affected accounts, reset credentials and sign out all sessions, turn on multi-factor authentication, export audit and sign-in logs now, then report through the vendor's official channel. CISA's #StopRansomware guide has a checklist you can follow.

We have no affiliation or commercial relationship with any platform listed here. A listing is not an endorsement or a ranking. Contact details come from each organization's own website (checked 2026-11-03) and may change. We list a phone number or email only when we read it on an official page. Spot an error? Tell us.
