About SMS-Worms

An SMS-Worm is a type of worm that distributes copies of itself to new victims - in this case, mobile phones - over the Short Messaging System (SMS) of mobile telecommunications networks. An SMS-Worm may be able to automatically send a copy of itself to every contact listed in the mobile phone's Contacts list.

Alternatively, the SMS may contain a link to a website. On clicking the link, the user may inadvertently download the worm's executable code onto their mobile phone, thereby infecting themselves. For this method to work, the mobile phone would need to have Internet-access capability.The SMS message will typically use an intriguing message in order to lure the user into reading and forwarding it, and possibly into clicking an included link.
