A growing number of cybersecurity vendors like CrowdStrike, Fidelis, FireEye, Malwarebytes, Palo Alto Networks and Qualys are confirming being targeted in the espionage attack.
The Mimecast certificate compromise reported earlier in January is part of the sprawling SolarWinds supply-chain attack, the security firm has confirmed.
Mimecast joins other cybersecurity vendors like CrowdStrike, Fidelis, FireEye, Malwarebytes, Palo Alto Networks and Qualys in being targeted in the attack.
A Mimecast-issued certificate used to authenticate some of the company’s products to Microsoft 365 Exchange Web Services had been “compromised by a sophisticated threat actor,” the email-protection company announced in mid-January. That caused speculation that the breach was related to SolarWinds, which the firm confirmed in an update this week.
