| PandaLabs: Adware and Trojans Caused Most Infections in July Trojans accounted for 26.65 percent of infections detected by ActiveScan, the online scanner from Panda Security, during July. This, combined with the percentage of infections caused by adware (24.83%), highlights how malicious codes used for financial gain are still the most active. Worms were the third most frequent malware type in July (8.3 percent of all infections). Backdoor Trojans (3.73%), dialers (3.28%), spyware (2.98%) and bots (2.32%), were also responsible for a significant number of infections. "There were also, however, numerous other types of malware whose individual percentages were not significant, but still accounted for 28 percent of all infections in total. Classified as 'Others' in this ranking, they include viruses, PUPs, hacking tools and many others", explains Luis Corrons, technical director of PandaLabs. The Downloader.MDW Trojan, designed to download other types of malware, tops the list of most frequently detected specific malicious code. After this comes Brontok.H, while in third place is the Lineage.BZE password-stealing Trojan. The Downloader.OZB Trojan is in fourth place in the ranking. In fifth place comes Sdbot.ftp, a script used by Sdbot worms to infect computers. Three Trojans, Downloader.PJT, Dropper.UN and Perlovga.A come next in the list of the most frequently detected malicious code. The last two places in the ranking are occupied by the Puce.E worm and a PUP (Potentially Unwanted Program) called SuperFast. Name - Previous position 1. "Trj/Downloader.MDW" - 1 2. "W32/Brontok.H.worm" - 2 3. "Trj/Lineage.BZE" - 7 4. "Trj/Downloader.OZB" - New 5. "W32/Sdbot.ftp.worm" - 3 6. "Trj/Downloader.PJT" - New 7. "Trj/Dropper.UN" - 5 8. "Trj/Perlovga.A" - 6 9. "W32/Puce.E.worm" - 4 10. "Application/SuperFast" - New. "There are six Trojans in this month's list. And this is largely explained by the popularity that this type of malware has among cyber-crooks, in particular because after the first infection it can drop a lot more malware onto computers and steal confidential information, etc.", explains Corrons. write your comments about the article :: © 2007 Computing News :: home page |
