Flame Malware Burns a Little Brighter

Posted June 5, 2012    Peter McCalister

Did you know that Microsoft’s Terminal Server Licensing Service (we’ll call it TSLS for convenience) generated certificates that could be used to sign code? No? Neither did Redmond.

This allowed Flame to propagate itself in a network by fooling other machines into believing it was serving Windows Update packages, when in actuality, it was serving up Microsoft signed versions of Flame. More details follow… but first, here is some actionable intelligence:

What does this mean for you and your organization? Apply this fix (Bulletin, Patch) immediately. Unless the patch is applied, your machines may end up trusting malicious code. Retina provides detection for the vulnerable certificates via audit 16497 – Microsoft Revocation of Fraudulent Certificates (2718704).
