Kaspersky Labs: Beware of New Breed of IM Worm

Kara Reeder

Kaspersky Labs is telling users to beware of a new family of computer worms spreading on a variety of instant messaging clients. According to V3.co.uk, researchers have discovered four variants of IM-Worm.Win32.Zeroll so far.


The malware is multi-lingual and is able to spread over several IM clients, like Yahoo Messenger, Skype and Windows Live Messenger, simultaneously. A malicious link in the message not only accesses the user's IM address book and sends itself to all clients, but also allows an attacker to gain control of the computer without the user's knowledge, downloading other malicious programs.
