According to various tech sources on the web, the Conficker worm might actually be doing something after all. CNET is reporting that the worm is beginning to replicate itself via P2P file sharing, and is downloading additional encrypted files that experts have yet to decrypt, but suspect are some sort of keylogger. All this is happening a little over a week after the April 1st supposed payload date passed by with little to no incidents. The actual propagation of the worm at this point is taking place gradually, so it may actually be more successful in doing damage than if it had hit all infected computers at once and started to keylog and replicate.
So, bottom line: if you haven’t patched your system, do it now. Then keep doing it.
