| ALIAS: | W32/Voltan.A@mm, I-Worm.Voltan, Marque |
| VARIANT: | Voltan.A |
The worm arrives in emails which contain a link to a web page from where a file could be downloaded. The emails contain text in Italian.
Il momento è catartico... per parafrasare un noto comico di ZELIG !!!
[The moment is cathartic... to paraphrase a famous comedian from ZELIG !!!]
then offers a file named 'zelig.scr' for download. 'zelig.scr' is to body of the worm.
When the file is opened it opens a webpage in the default browser with the following content:
Congratulazioni ! Il "CATARTICO" screen saver è stato installato con successo .
[Congratulations ! The CATHARTIC screen saver has been successfully installed]
It creates a value in the registry as
'HKLM\Control Panel\Screen Saver.Marquee\text'
with the text:
A volte ti sento cos? vicina...A volte ti sento cos? lontana ...Certo che hai proprio un cellulare di m**da!
[Sometimes I can feel you so close...Sometimes I feel you so distant ...You sure have a sh*tty cell phone!]
To send emails Voltan first locates the Windows Address Book and reads the list of contacts from there. Using its own SMTP engine it sends the following emails to the contacts:
From: user@of.infected.computer To: friend@of.the.user.of.the.infected.computer Subject: Il momento e' catartico [The moment is cathartic]
Body: Ricevo e cortesemente inoltro,.... un premio per la genialita hanno reso mitico un salva schermo scaricalo, "poesie catartiche", che non sai cosa ti perdi
ciao
[I received this and I'm forwarding it,... an award to genius they made this great a screen-saver download it, "cathartic poems", you don't know what you're missing]
If the worm can not find the email address of the user of the
infected computer it uses a hardcoded address instead.
Voltan uses system DLLs which are not available on some
systems. The worm does not work on Windows 95/98/ME and
Windows NT4.
