We have found a new malware that uses instant messaging to deceive users. It arrives as an .exe file disguised as a .jpg. If you open it, you will get infected, and your msn contacts will receive some messages and a file called “fotos_posse.zip“.

Here it is a picture of how the messages look like. For those of you who don’t know Spanish, here it is the translation “Hello”, “I hope you like the photographs” and the attachment.

It is been quite active, as you can see in the following evolution graphic of the messages received in the lab in the last 72 hours.
