Bangalore: BitDefender has identified a malware-spreading mechanism targeting people seeking to unlock their iPhones. Users can get an e-mail offering a link that promises a new version of an iPhone unlocking application. Users click the link to overcome vendor set network restrictions and those link are then directed to a webpage which provides instructions on how to download the unlocking application. By connecting iPhone to a personal computer, users are then instructed to download the 'new modified' application and run it on the iPhone. However, once downloaded and run, the executable file causes a Trojan virus in the computer. BitDefender has identified that this piece of malware comes as a Windows batch file packed alongside the iPhone unlocking application. The Trojan attempts to change the preferred DNS server address for several possible internet connections on the users' computers. This allows the malware creators to intercept the victims' calls to reach internet sites and to redirect them to their own malware-laden versions of those sites.
