Wondering if anyone else is experiencing this, we are currently using Office 365 and I think we are going through a targeted attack.
I have a policy in place to block .exe file attachments, over the past 12 hours almost every email account in our company (including alias and distribution groups) has been sent a malicious email... Thankfully they are being blocked, but I am now concerned there may have been some data leakage on Microsofts end, we don't have an extensive listing of all our internal accounts listed anywhere... These emails are even being sent to internal only distribution lists, across two different domains...
Anyone experiencing a similar situation at the moment?
