.The Virus

So I was checking Rano's Site the other day and I saw something interesting. It's about the trojan link in the MSN Messenger. So what is it all about? Well, I'm sure most of us have experienced this; when one of your contact just private message you sending links to your picture, games etc, and when you look at their status they are actually offline. The links would look something like this.




Let me share my some of my knowledge to you my dear readers. Above are some examples of what is sent to you by the victims of this trojan.

It contains a link which is optional to press, and this link is supposedly gonna show of this picture. Nosy receivers click the link and they can then start regretting.

What happens when you press the link, is that your computer downloads a so called 'Downloader', a small program clip that again downloads a more vicious code. We are talking about a "bot-code", who in short terms means that the infected computer connects to a network who can be controlled by others, say Head Director Christophe Birkeland in NorCERT, a sub-department of National Security Authority who works secifically with IT-threats. In other words, if you click on the link, you would somehow become a "puppet" controlled by a stranger. In the IT Security world, people refer these PCs as a zombie PC, where it can become one of its puppet to hack into large organisation without exposing themselves. Plus, when you are affected by the trojan, the frightening thing is, it is very hard to detect it. Results shows that under half of the 30 anti virus program that was tested could not spot the trojan.

So what do you need to do when you get this links? My advice:

1. No matter how tempting or convincing the link might be, DO NOT attempt to click on it. The trojan has what we call a spreadvector, which adapts to the language your operatve system is in.

2. Check whether your contact is online.

3. Let them know that their machine has been infected by the trojan. And tell them to reinstall their Messenger.

Note that this virus only affects Windows Operating System. So Mac or Linux users who are connected to the MSN will have nothing to worry about.
