GDMME recommended actions
GDMME recommendations · automatically organised from explicit products and source signals, without individual human analysis. Confirm applicability against vendor guidance and your environment.
- Locate Microsoft 365 deployments, running versions and service owners in your inventory or management console; compare them with the vendor applicability criteria. A named product does not mean every deployment is affected.
- Check unfamiliar sign-ins, MFA-method changes, mail-forwarding rules and new app consents on relevant accounts with the user and administrators. Retain timestamps, sources and response records.
- If credentials were entered, an app was authorised or theft is suspected, use trusted administration channels to revoke relevant sessions/tokens, reset affected credentials and review MFA. Identify affected accounts and services rather than only deleting the message.
