Microsoft Corporation:
You can’t clean a compromised system by using some “vulnerability
remover.” Let’s say you had a system hit by Blaster. A number of
vendors (including Microsoft) published vulnerability removers for
Blaster. Can you trust a system that had Blaster after the tool is
run? I wouldn’t. If the system was vulnerable to Blaster, it was also
vulnerable to a number of other attacks. Can you guarantee that none
of those have been run against it? I didn’t think so.
You can’t trust any data copied from a compromised system. Once an
attacker gets into a system, all the data on it may be modified. In
the best-case scenario, copying data off a compromised system and
putting it on a clean system will give you potentially untrustworthy
data. In the worst-case scenario, you may actually have copied a back
door hidden in the data.
