AWS ConsoleLogin with MFA triggered Impossible Travel scenario


Detect an Impossible Travel event when a @userIdentity.type: {{@userIdentity.type}} performs a consoleLogin with a multi-factor authentication (MFA) device.


The Impossible Travel detection type’s algorithm compares the GeoIP data of the last log and the current log to determine if the user with @userIdentity.session_name: {{@userIdentity.session_name}} traveled more than 500km at over 1,000km/h and the user used MFA.

Triage and response

  1. Determine if {{@userIdentity.session_name}} should be connecting from {{}}, {{}} and {{}}, {{}} in a short period of time.
  2. If the user should not be connecting from {{}}, {{}} and {{}}, {{}}, then consider isolating the account and reset credentials.
  3. Use the Cloud SIEM - User Investigation dashboard to audit any user actions that may have occurred after the illegitimate login.
