Cybersecurity firm Malwarebytes on Tuesday revealed that it too was targeted by the hackers who breached the systems of Texas-based IT management company SolarWinds as part of a sophisticated supply chain attack.

Malwarebytes says it has not used any SolarWinds products, but its investigation revealed that the threat actor gained access to some of its systems by abusing applications with privileged access to Microsoft 365 and Azure environments.

According to Kleczynski, his company discovered the breach after being notified by Microsoft on December 15 about suspicious activity possibly conducted by the SolarWinds hackers.

FireEye on Tuesday released a detailed white paper on the techniques and tactics used by the SolarWinds hackers to target Microsoft 365 environments.

The cybersecurity firm also released an open source tool designed to check Microsoft 365 tenants for the use of techniques associated with the SolarWinds hackers.

Cybersecurity researchers continue to analyze the tools and tactics used by the SolarWinds hackers.
