The Microsoft Threat Intelligence Center (MSTIC) tracks nation state and criminal actors to protect Microsoft and Microsoft’s customers. The actors we track are often highly technical, and maintain good operational security. Tracking actors like this requires persistence and ingenuity and is done by combining intelligence analysts, reverse engineers, developers and data scientists.

Some of the successful investigations that MSTIC has performed include discovering and disrupting supply chain attacks from North Korean actors, identifying attacks from Iranian actors against universities and research organisations, and monitoring new techniques deployed by Russian actors.

MSTIC also co-operate with the Digital Crimes Unit (DCU) to prevent cybercrime, particularly ransomware.
