About this tag
Authenticode is Microsoft's code signing technology used to verify the origin and integrity of software binaries on Windows. Discussions on WindowsForum.com cover security vulnerabilities in Authenticode signature verification, including CVE-2025-55229 which allows certificate spoofing, and earlier flaws like MS10-019 that could enable remote code execution. Administrators will find threads on Microsoft's deprecation of SHA-1 for code signing, changes to Authenticode verification in 2014 that reject non-compliant signatures, and issues where signed drivers appear as unsigned. The tag also includes advisories on policy updates for the Microsoft Root Certificate Program affecting Authenticode certificates. These topics are relevant for IT professionals managing Windows security, software deployment, and driver signing.
