However, just because April 1st came and went doesn't mean the threat is gone and we can just pretend Conficker never existed. April 1st was just the kickoff of the new Conficker behavior, but not necessarily the end of it. Now its a week later and security researchers are starting to report that they are seeing a new payload being delivered to PC's compromised with Conficker. The payload, apparently being delivered via the peer-to-peer (P2P) networking component of the worm, is still being researched but appears to at least have a keystroke logging component that can capture sensitive information such as usernames, passwords, credit card numbers, and more.
In related news there is also a Conficker copycat circulating in the wild. Neeris is making the rounds via instant messaging clients. If you haven't already (and *if* you haven't- why haven't you???), make sure you apply the MS08-067 patch.
