Feak is a proof-of-concept worm that was created and publicly released by researchers at the University of California, Santa Barbara.

The source code of the worm is also available along with the binaries on the Internet. While Feak is a fully functioning worm, its ability to spread is limited due to an included safety mechanism. The worm in its original form starts sending SMS messages to everyone in the phone's contacts list if it finds a contact named "HACKME". The SMS messages that are sent contains the URL to download the worm.
