Death of the IM-Worm ?

This article examines the evolution of the IM worm since the beginning of 2005. It is written from a European standpoint: this means that it does not include information about certain IM-Worms which did not spread widely in Europe. It also does not cover the topic of malware for certain IM clients such as icq, which are less commonly used in Europe.

Although the first IM-Worm appeared in 2001, this type of malware didn’t become really common until the beginning of 2005. If we take a look at this period, it becomes clear that it’s very important to differentiate between IM Worms which were written with a range of aims.
