The creator of the Marq email worm has received a 14 month
sentence and been fined 3,000 Euros for writing a computer worm
which dialled premium-rate phone numbers, which tried to steal over
100,000 Euros (approximately £71,000).
The man wrote the W32/Marq-A email-aware worm
(also known as Voltan or Zelig) to direct innocent computer users
to a website where a malicious program posing as a screensaver
could be downloaded. If run, the worm would change the phone number
used for accessing the internet to a premium-rate number based in
Aruba in the Dutch Antilles at the cost of 1.80 Euros per
It is claimed that more than 57,000 minutes were logged on the
premium-rate number in just three days at the end of October 2003.
If the virus had been allowed to continue, it is estimated that 1.2
million Euros would have been stolen every month.
The Italian financial police were able to freeze the money
accrued by the worm, which was first sent to a New York bank
account, then transferred via Venezuela before ending up in an
account belonging to a "ghost" company in Aruba.
The crime was discovered and blocked after the man, who although
born in Pisa lives in Venezuela, came to Italy to increase the
number of premium rate telephone connections.
The virus writer, who was aged 39 at the time of his arrest by the
Italian authorities in November 2003, is thought to have avoided a
harsher sentence because it was his first offence and he
co-operated with the authorities in their investigation.
The Marq worm arrived in the form of an email with the subject
line "The moment is cathartic", written in Italian, directing users
to download what was claimed to be a screensaver called zelig.scr.
Flavio Oreglio, one of the stars of the Italian TV comedy show
"Zelig", is the author of a book called "The moment is cathartic"
and it is suspected that this encouraged some Italian-speaking
people to download the malicious program.
"More virus writers are being caught and convicted than ever
before, and the Italian authorities did well to cut this worm's
author down to size," said Graham Cluley, senior
technology consultant for Sophos. "Increasingly we are seeing
viruses and worms which are designed to steal money or resources
from the infected computers of innocent people. Everybody should
make defence of their computers a priority if they wish to connect
to the internet."
Sophos recommends companies protect themselves with a consolidated solution which can defend businesses
from the threats of both spam and viruses.
