Brief 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.


Technical Description
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)"
