Analyzing the MD5 collision in Flame
Summary: The Flame malware used an MD5 collision attack to infect new machines through Windows Update, marking the first such attack discovered in the wild.

What you should know: A collision attack against MD5 was long treated as an academic concern until Flame used it to push malware through Windows Update itself, so any system still trusting MD5 for integrity or trust decisions is relying on a primitive that has now been broken in live operations.
