Mimecast may also have been a victim of the SolarWinds hack campaign

Mimecast could also be a potential victim of the recent SolarWinds hack as the company has revealed that one of its certificates used to authenticate its products to Microsoft 365 Exchange Web Services was compromised by a sophisticated threat actor.

The email and data security company said the compromised certificate is used to authenticate its Sync and Recover, Continuity Monitor and Internal Email Protect (IEP) products. However, it wasn’t Mimecast that discovered the compromised certificate but rather Microsoft.
