  • Mimecast has become the latest cyber security vendor to reveal it has been the victim of a hacking attack.
  • Mimecast is now asking these customers to “immediately” delete the existing connection within their Microsoft 365 tenant and re-establish a new certificate-based connection using a new certificate it has created.
  • Three security experts suspect the hackers who compromised Mimecast were the same group that broke into SolarWinds and a number of sensitive US government agencies.
