PROBLEM: A new worm named Swen appeared this morning masquerading as a patch for a
Microsoft Windows patch. The spread of the worm is being helped along by computer users
who dutifully install the patch (worm) and pass it on.
PLATFORM: Windows
DAMAGE: Helpful users install and pass on the worm.
SOLUTION: 1. Keep your antivirus software up to date.
2. Do not execute attachments that you are not expecting.
3. Do not install patches received as e-mail attachments.
VULNERABILITY ASSESSMENT: The risk is HIGH. Current viruses and worms install
backdoors in systems that allow remote intruders to take over and use those systems.
Usage includes spying, industrial espionage, e-mail spamming, creation of porno sites,
proxy servers, etc.

I've been getting a lot of spam from Microsoft today. This raised my suspicions and
I checked at http://ciac.llnl.gov/ciac/ and found the following warning. I haven't
sent this type of warning before, but I hope some of you will not fall victim to
this latest worm, since it looks quasi-official by posing as being from Microsoft.
