Microsoft Instant Messenger Virus Sweeps Net

Many people have reported a Warhol virus affecting users of Microsoft Instant Messenger. If you get messaged, "Go To http://www.masenko-media.net/cool.html NoW !!!", or any similar message (apparently there are several websites with the infection code), I suggest not following the link. A brief discussion follows.

Sequence: Get messaged "Go To http://www.masenko-media.net/cool.html NoW !!!" or something similar with another URL. Follow the link. That webpage contains malicious code which gets your messenger contacts and sends a similar message to your contacts. It looks like it uses a vulnerability in formmail.pl as well, although I'm not exactly sure how (I'm not an expert in ECMAscript, sorry, and I have no systems that could possibly be affected by this to test with). I'm sure some of our readers can provide more information in the comments below.

There appear to be several webpages which carried the infected code, not just masenko-media.net. Some webmasters are already taking them down.

Sophistication: moderate. Damage: only your pride.

Solution: probably the latest mega-patch for Internet Explorer will fix the Microsoft bug that allowed this.

Risks: obviously, the code could have done worse than just messaging your contacts. With Microsoft making "messaging" an integrated part of the operating system, any flaws in it can be exploited to affect millions of people instantly, so it is a high-value target. Does it have commensurate high-strength security?

Javascript flame

[Sloppy]

I don't get it... why do people whine about this? Just disable Javascript. Everything worthwhile on the web will still work just fine; it'll just go faster and screw you less often. Javascript should be extinct by now: Everyone who uses it hates it, people who turn it off are happier (I have never seen those x10 pop-under ads that everyone talks about), and it doesn't do anything useful. It's all pain with no gain.

Web browsers shouldn't even include it anymore.
