04:01:02 The trojan inside Kazaa, BearShare, LimeWire and Grokster.
A Trojan ('trojan horse', a program that seems to do something and instead do anything), has been identified in more recent versions of BearShare, LimeWire, Kazaa and Grokster. It is 'W32.Dlder.Trojan' and is contained in ClickTillUWin, an application that promises chanches to win prizes. According to F-Secure DlDer track the url that the user visits by posting them on a dedicated website and opens a security hole by downloading and activating the executable files. The technical manager of Limewire said to be in the dark, as the administration of the promotion was entrusted to the Cydoor, who has done for the application as a shortcut to another software. DlDer is installed during the setup and then download the application 'explorer.exe' by placing it in the system folder. Since then regularly sends data to the site in 2001-007.com (which corresponds to the domain Clicktilluwin.com). And user reports seem even more serious, since on Limewire is also installed if the user specifies to the contrary and, according to other technicians, would be able to change the configurations of the firewall to access the network without any permission. On the other hand the site Grokster was posted software that erases DlDer user's machine, while Kazaa has not yet taken any steps in this regard.
