Infections may be coming from single source
29 July 2004
A single virus writer could be responsible for as much as 70 per cent of infections affecting the Internet, according to antivirus firm Sophos.
According to Sophos, the individual responsible is Netsky and Sasser author Sven Jaschan, who was arrested earlier this year.
The findings are the part of a six-month malware round-up published by the firm.
During the five months preceding his arrest, there were at least 25 variants of Netsky and one of the port-scanning network worm Sasser.
According to reports on znet.co.uk, Graham Cluley, senior technology consultant at Sophos, was staggered that one person could be responsible for so many infections.
Cluley noted however that there is still a chance that others may be implicated in the Netsky virus, despite no arrests having been made as of yet.
"The full story of the Netsky gang isn't known yet. We know some of his fellow students have been questioned, but the real motives are not fully known," said Cluley.
According to the Sophos survey, the Sasser worm virus accounted for 26.1 percent of infections. This was followed by, Netsky.P, Netsky.B and Netsky.D, which were the second, third and fourth places respectively.
