Dasher "B" worm begins spreading in the wild

By Justin Mann on December 16, 2005, 11:52 AM
There are now reports of the Dasher B worm being found in the wild, after a previous version ended up being quite a dud due to bogus code. The revised worm targets a vulnerability in Windows machines, particularly Windows 2000, and goes so far as to install a keylogger on the machine as well as render it vulnerable to remote control, making it a serious threat to consider. According to some, the provided fix may have had some difficulty in original deployment:

"The worry is that the problems with the patch may have prevented it from being successfully rolled out onto some vulnerable computers," said Graham Cluley, senior technology consultant at anti-virus firm Sophos.
The patch to address this exploit is already available, and has been for several months now, which is another good reason to always keep your machine up to date with security fixes. If you are utilizing automatic updates you should already have the patch in place, though it's still good to check.

Maybe it's nothing, but I came across someone asking me for help online the other day - it turned out that she had a keylogger installed. Since then her Ebay account has been stolen (and since stopped after reporting it to ebay), and other quirky things like not being able to even view the status of the windows firewall.Is there anywhere anybody knows of that offers information on what the "two programs" this worm attempts to download are? It may be nothing, but worth double checking I'm sure.

It is probably randomized once it is run, so it would be difficult to detect by name alone

Well, I guess so, but still it would tie in with what I say the other day The keylogger was minikeylog, but its files didn't seem to exist - not by their known filenames anyway. Maybe it was related, and maybe not. Who knows.I just wish that virus encyclopedia pages would offer a little more detail on exactly what these various things do.That aside though, it'll be interesting to see hw far this thing spreads, and so see just how on top of windows updates people are these days.

Though w updates is very useful, the unfortunate people who have gotten it pirated will get their just desserts.
