Virus writers are using sophisticated technology to fight back against anti-virus suppliers, a report from Kaspersky Lab reveals.
Hackers are developing websites that load Trojans onto end-users’ machines but delivered innocuous files to anti-virus companies.
Other Trojans monitor firewalls and automatically click yes to alerts asking if the Trojan’s activity is permitted.
Another technique is to wrap known viruses in multiple packets, known as packers, which hide the file from virus scanners.
Kaspersky said that cybercriminals were modifying existing packers at a rapid rate to evade anti-virus signatures.
The percentage of viruses that contain payloads which target anti-virus software is also growing.
Malicious programs now exist that are designed to destroy dozens, if not hundreds, of security solutions.
Cybercriminals have responded to security counter-measures introduced by anti-virus companies by creating viruses with kernel-mode code which can modify the operating system.
“Over the next several years, IT security companies will be able to use all their resources to reduce the pressure exerted by malicious users, but it will become ever more difficult,” the report concluded.
