Apparently, rogue servers listening on the p2p Kad network intercept the search terms of queries and generate on the fly appropriate file names linking to files that contain malware.
For a example, a random search term, like "give me malware", will return the following file names.
give me malware_fastest_BitTorrent_downloader.exe give me malware_Web_Hottest_Videos_Personal_Player.exe give me malware_ShareAccelerator.exe give me malware_using_emule_multimedia_toolbar.zipAs the image below demonstrates, the availability of these files is also doctored to look artificially high. (Yes, I know that one shouldn't use unknown servers.)
Two virus scanners didn't find anything suspicious in the files. Specifically, I run Clamwin and Vasilis Prevelakis Symantec antivirus without obtaining any warnings. However, Panagiotis Louridas running Avira AntiVir suceeded in identifying two of the four malware programs:
viri/give me malware_ShareAccelerator.exe [DETECTION] Is the Trojan horse TR/Drop.HotWebBar.C viri/give me malware_Web_Hottest_Videos_Personal_Player.exe [DETECTION] Contains signature of the dropper DR/WhenU.A.9According to Avira, the two malware programs were added to the definition file on February 5th, 2007.
Moral: malware writers are getting increasingly sophisticated; antivirus programs are trailing behind.Read and post comments.
