Smarter viruses fuel big increase in spyware
September 30, 2005
According to the monthly virus chart from security firm Sophos, virus writers are getting a lot more smarter, using smaller malware that performs certain specific tasks instead of trying to inflict mass virus outbreaks. Reportedly, the most common infection this month was Netsky P, a worm virus first identified in February 2004.
Mytob variants accounted for over half of all virus infections, taking eight of the top 10 positions.
"Smaller, targeted attacks are on the increase with the emergence of a new breed of financially-motivated online criminal," said Carole Theriault, senior security consultant at Sophos.
"The concern is that if users continue to combine unsafe computing practices with outdated threat protection, they will be a soft target for this new form of attack."
Theriault added that the appearance of Netsky at the top of the chart raised some serious questions about PC users' levels of protection.
The prevalence of a worm of this age indicates a body of users who are taking no precautions at all and acting as a reservoir of infection for the rest of the online community.

This group may also be responsible for the large amounts of spyware in circulation last month, according to security vendor Fortinet. Infected PCs under slave control to a virus writer are becoming an increasing problem.
"Most malicious emails are spammed via infected hosts, so a rise in spyware activity is likely to reflect a trend in cyber-criminal activity," said Guillaume Lovet, threat response team leader at Fortinet.
"Now that large-scale nets of infected hosts (i.e. botnets) have been well established for a while, the commercial activities of their owners are flourishing.
"The two most lucrative are the relaying of spam and phishing attacks, and the aggressive seeding of spyware."
Fortinet's survey identified US users as the top target for spyware attacks, representing nearly 30 per cent of reported infections.
Korean users were the next most popular targets, possibly due to the high levels of broadband use in the country.
