At least 75%of all new malware that appeared in the third quarter of 2007 were Trojans. This is according to figures from PandaLabs.
“Trojans are still, by far, the most numerous category of new malware. This is because this type of malicious code is an ideal tool in the new malware dynamic, where cyber-crooks seek to profit from their attacks,” explains the CE of Panda Security (South Africa), Jeremy Matthews.
Adware (12%) and worms (11%) were the other categories of malicious code with a significant number of new strains over the last three months.
In terms of the number of infections, Trojans also headed the list. During the third quarter they accounted for 32% of malware detected on computers of users of the Panda ActiveScan online scanner. Adware was in second place with an infection ratio of 24%.
The PandaLabs report on malware activity in the third quarter of 2007 also offers a comparative review of kits for installing malware using exploits. These malicious tools allow cyber-crooks to exploit vulnerabilities on computers and servers to infect users.
“By comparing these kits we can get a clear idea of the current malware situation. Cyber-crime has become professional to the extent that hackers have a range of tools, with their corresponding prices and features, from which to choose from when carrying out attacks,” says Matthews.
