Of all the malware infections, 80 percent are the result of Trojans, a new report said.
“Cybercriminals use Trojans as a key tool to infect users, continually introducing changes to avoid detection, and, in many cases, automating the process of changing the Trojan,” said Luis Corrons, technical director of PandaLabs, which conducted the second quarter 2013 threat report. “They use scripts and special tools in order to change the binaries run on victims’ computers to evade the signature-based detection used by antivirus firms.”
In addition to the malware infections, 77 percent of all new malware is a Trojan, while worms make up 11.3 percent, and viruses, 10.3 percent, of new malware, according to PandaLabs. When it comes to malware infections, 79.7 percent are because of Trojans, 6.7 percent due to viruses, and 6.1 percent worms.
Overall, the volume of new malware samples rose in Q2 — 12 percent more than the same period in 2013, and 17 percent more than the first half of the year.
China is home to the most infected machines, with 52.4 percent of infections, followed by Turkey, with 43.6 percent, and Peru, 42.1 percent. Europe has the lowest infection rates.
