Besides that, there are plenty of rumours about a possible Conficker attack on 1st April. I know you may think it’s all hype or scaremongering, and it might well be. But, if you run a large corporate network I’m sure you don’t want to sit down and wait until 1st April to find out.
If that’s the case, you have to know that the Honeynet Project has been working on a way to detect Conficker-infected machines and that they have just released a scanner for this task. The scanner is available as a python script and as a windows .exe executable, and can be used to scan a single host or a whole network range.
