Posted June 5, 2012    Peter McCalister

Flame leveraged a “0day” (zero day) within TSLS to sign its own code, allowing it to appear as if the code came from Microsoft. 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.
