Microsoft Disrupts Malware-Signing Service Abusing Artifact
🔒 Microsoft says it disrupted a malware-signing-as-a-service operation that abused its Azure Artifact Signing platform to generate fraudulent short-lived code-signing certificates used by ransomware gangs and other cybercriminals. The actor, tracked as Fox Tempest, created over 1,000 certificates and hundreds of Azure tenants and subscriptions. Microsoft seized the signspace[.]cloud domain, took virtual machines offline, revoked certificates, and filed a lawsuit in the Southern District of New York.
