Dasher B worm exploits Microsoft security vulnerability on Windows 2000 computers


The W32/Dasher-B worm exploits a vulnerability in Microsoft Windows Distributed Transaction Coordinator (MSDTC) first announced by Microsoft in October. The worm opens a backdoor on vulnerable computers and causes them to connect to a remote server for further instructions. Windows 2000 computers which have not been patched are most at risk from the worm.

"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."
