This morning I received a number of phone calls from 000018776686536. It was a Microsoft phone verification call for a sign-in (2FA?) however I have not received any email indicating an attempted sign-in.I just ignored it, the automated voice then said "I'm sorry, we cannot sign you in at this time, please try again later."

 

Anyone else had this recently?

Do you use O365 with MFA?
Our MFA source number was blocked recently by Spark and Vodafone. If some clown is putting random numbers in and triggering MFA calls then no wonder it got blocked.

Other option if you do use MFA is that your O365 username and password have been compromised and the attacker is using alternate MFA option to get in hoping you'll press the # key.

Strange, because 2FA should only initiate the call when the user enters a valid username and password combination. Time to change password?

I do have O365 however 2FA is not active (I can't see an option to turn in on?). The number called me on my landline and my landline is not among the MFA options. My mobile is.

 

Edit: Found 2FA option, now active.

Sounds like another O365 user has mistakenly entered your landline number as their MFA contact number.
