An appropriately names worm called Dasher-B is floating around as the holiday season is upon us. Sophos Labs came out with a statement regarding the new worm, which exploits vulnerabilities documented by Microsoft earlier in the year. Sophos is warning people to update their anti-virus protection and security patches are up-to-date.
The W32/Dasher-B worm works over a vulnerability in Microsoft Windows Distributed Transaction Coordinator (MSDTC). The vulnerability, announced back in October, creeps in a backdoor and causes the computers to connect to a remote server for further instructions
"The Dasher worm wouldn't be able to spread at all if the security vulnerability in Microsoft's software didn't exist. It's important that all companies have a mechanism for rolling out security patches, as well as for automatically updating their anti-virus software," said Graham Cluley, senior technology consultant for Sophos. "Microsoft will be fuming that a virus writer is successfully exploiting another vulnerability in their operating system."
Microsoft has had a number of recent problems with the patches in recent months. This is one more problem, albeit a little later, with those patches.
"The worry is that the problems with the patch may have prevented it from being successfully rolled out onto some vulnerable computers," continued Cluley.
The best way to beat this worm is still to keep your Microsoft patches up-to-date and also make sure your security software is current. If users have done this then they shouldn't have any problems.
