Great use of the word likely in context of an investigation for which data may not be conclusive. When not fully sure, likely is a good word to choose.
Their 2nd tweet tells the story, it was 2FA, the lack of it, plus “likely” an easy to guess password…
Kudos for the report!
We have finished our investigation into last week's Mandiant X account takeover and determined it was likely a brute force password attack, limited to this single account.
