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.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.
You may also refer to the Knowledge Base on the F-Secure Community site for more information.
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.
