What are “LSASS”, “LSASS.EXE” and “Sasser” and how do I know if I’m infected? What do I do if I am?
The Sasser worm is the most recent and one of the most virulent viruses to impact Windows-based systems. Unlike previous outbreaks, Sasser doesn’t even need you to use email or even be at your machine to infect your computer and continue spreading. It exploits a recently patched vulnerability in something called LSASS.EXE.
Yep, it’s a nasty one and an example of sophisticated virus attempts yet to come. Even if you’re not infected this is an opportunity to review and implement the steps to keep your computer safe.
