More Information
W32/Combra-C is an email worm for the Windows platform.
W32/Combra-C will arrive as a greeting card email message, informing the recipient to click on an indicated link to view the greeting card. The email message contains the following text:
Ola <Name of recipient> <Recipient's email address> ,
<Sender's email address> Ihe enviou uma mensagem!
Veja o cartaeo que preparei para voce!
<fake link>
Voce tambem podera visualiza-lo colocando o numero de seu cartao:
<fake link>
The fake link will appear to point to a legitimate website, when if clicked upon, it will download a copy of the worm as a screensaver file. The worm will look up the web address book's email addresses and use that information in turn, to send email messages of a similar nature to spread itself.
W32/Combra-C sets the following registry entry to ensure its automatic execution:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
winupdatefiv_
<path and filename of worm>
The worm will attempt to download and run an executable file from a remote website. The downloaded file is called CRSS3.EXE at the time of writing. This file is a Trojan and is detected by Sophos as Troj/Bancban-CQ.
