Microsoft, supported by Resecurity, disrupted Fox Tempest—a commercial malware-signing service that abused Microsoft Artifact Signing to provide fraudulent code-signing certificates to cybercriminals—by seizing the signspace.cloud site, taking hundreds of virtual machines offline, blocking hosting infrastructure, and revoking more than 1,000 certificates; Microsoft linked the operation to multiple ransomware and malware families, illustrating the high impact of degrading upstream code-signing ecosystems.
