Critical Insight MDR for Office 365 investigations include:

  • Account Takeover: A user’s Office 365 account is hijacked and then fully controlled by the bad actor.
  • Brute-Force Attacks: A bad actor uses automated software to generate a large number of attempts at attaining the desired data, often for password cracking.
  • Impossible Journey: A user logs in from LA and 20 minutes later from Europe. It could be VPN use, or it could be something else.
  • Unusual Location: A user logs in from a location they rarely or never visit, even though they may have gone there.
  • Compromised Credentials: A user succeeds with password authentication but fails 2FA many times.
