Microsoft Defender Flags Legitimate DigiCert Certificates as Trojan

Why it matters: Indian organizations using Microsoft Defender on Windows systems must be vigilant for these false positives to avoid service disruptions caused by the removal of essential certificates.

Microsoft Defender is erroneously identifying legitimate DigiCert root certificates as Trojan:Win32/Cerdigent.A!dha. This widespread false-positive issue is causing alerts and, in some instances, the removal of critical certificates from Windows systems. Operators must be aware of this issue to prevent unnecessary remediation or operational disruption.
