Threat description
Cervivec is a mass-mailer worm written in Delphi. The code body is over 600 kilobytes in size. It collects e-mail addresses from the user's ICQ contact database.
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.
F-Secure customers can request support online via the Request support or the Chat forms on our Home - Global site.
The worm installs itself to the Windows System directory as "ntkrnl.exe" and adds a value to the registry to
"Software\Microsoft\Windows\CurrentVersion\Run\Kernel Loader"
to make sure that it will be started when the machine starts up.
It sends e-mail messages in different languages:
"Cau posilam ti cerviky tak se na to podivej (virus to neni)" "Cau posielam ti cerviky tak sa na to pozri (virus to neni)" "Hallo, Ich habe ein guter Witz-Wurm so sieh! (kein virus)" "Hi, I have some cool joke - worms so have a look at it (no virus)" "J'ai une bonne blague ca s'appelle verre de terre alors jette un coup d'oeil (il n'y a pas de virusi)" "Czesc, mam swietnz dowci te mando los gusanilloes. Pues mirarlos (no es un virus)" "Hola te mando los gusanilloes. Puesmirarlos (no es un virus)"
F-Secure Anti-Virus with the latest updates can detect this worm.
