HollowFrame Loader Uses Fake Python DLL to Evade Microsoft Defender Detection

The HollowFrame loader was identified using a fake Python DLL to conceal malicious Go code, evading detection by Microsoft Defender. Attackers pre-staged Defender exclusions to bypass security measures before deploying the payload. The technique involves disguising the malicious DLL as a legitimate Python component to execute unauthorized code. No specific dates, CVE IDs, or victim organizations were disclosed in the report. The impact includes potential unauthorized access and execution of malware on compromised systems.
