A worm is a parasitic program capable of replicating by sending copies of itself to new hosts (computers, servers, mobile devices, etc) over a network and other transferable media.
At one time, worms were considered more of a nuisance than a threat, but today it has become increasingly common among malware authors to create malicious, complex worms that can perform malicious activities such as data-stealing or launching Denial of Service (DoS) attacks. Worms may now also be used to deliver other threats, such as viruses or trojans.
There are multiple worm sub-types, which are defined by the platform or medium they use to spread:
- An Email-Worm will spread copies of itself using e-mail messages
- An IRC-Worm spreads through Internet Relay Chat (IRC) channels
- An SMS-Worm multiplies using the Short Message System (SMS) of telecommunications networks.
