Subject: Latest Virus Threat
May 1, 2004. A new email virus is spreading throughout the internet namely Sasser. This virus can spread without any user interaction. It was introduced this weekend and has already infected hundreds of thousands of PC's. Listed as a Category 4, this is the highest rated threat of the year. The virus is causing a general slow down of the entire internet as it is generating lots of traffic.
To protect yourself from this virus, make sure your firewall is installed and working properly; you have the latest windows security updates installed; and your virus definitions are up to date.
We at MBSII.NET have implemented all of the above solutions on our systems and will continue to protect our customers from all virus threats. Below are some technical details about the worm.
W32.Sasser.B.Worm is a variant of W32.Sasser.Worm. It attempts to exploit the LSASS vulnerability described in Microsoft Security Bulletin MS04-011, and spreads by scanning randomly selected IP addresses of vulnerable systems.
W32.Sasser.B.Worm can run on (but not infect) Windows 95/98/Me computers. Although these operating systems cannot be infected, they can still be used to infect vulnerable systems that they are able to connect to.
The virus uses TCP ports 445, 5554, and 9996.
