Cheese

Threat description

Details

Summary

Cheese is a worm that is able to propagate from a Linux based system to another. It scans random Class B subnetworks for machines that are infected with a Lion worm, and if such systems are found, it copies itself to the victim to to directory "/tmp/.cheese".



Removal

Automatic action

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 scanning & removal options

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.

Contact Support

F-Secure customers can request support online via the Request support or the Chat forms on our Home - Global site.

Technical Details

When the worm executes, it removes all lines that contain string "/bin/sh" from the "/etc/inetd.conf" and restarts inetd service. This effectively removes an open shell installed by Lion worm.

After that Cheese will start to scan for other machines to infect.
