Like a wicked mobile cousin of Firesheep, FaceNiff could allow even a clueless noob to hack Facebook over Wi-FI networks. The hacking app requires root access on Android phones. FaceNiff allows users to sniff and intercept web sessions for Facebook, Twitter, YouTube, Amazon, and Nasza-Klasa (a Polish site). Unlike Firesheep, the FaceNiff app listens in on wireless networks encrypted with WPA and WPA2 (WEP too) so that with one tap and within seconds, users can hijack the account types supported.
Not that you intend to try out FaceNiff, but you can't hijack more than three profiles. However, FaceNiff app developer Bartosz Ponurkiewicz says more sites for hopping onto user accounts will soon be supported. He noted if you want to hijack more than three profiles with FaceNiff, there will be an option to pay and unlock the code.
FaceNiff has been confirmed to work on rooted mobile phones: HTC Desire CM7, original Droid/Milestone CM7, SE Xperia X10, Samsung Galaxy S, Nexus 1 CM7, HTC HD2, LG Swift 2X, LG Optimus black (original ROM), LG Optimus 3D (original ROM), and Samsung Infuse.
Watch How Can It Be Done::::
While we are on the subject of Androids and apps, Lookout Mobile Security reported finding 26 malware-laced applications in the official Android Market. The smartphone security firm said the infected apps are a "stripped down version of DroidDream" and were probably maliciously crafted by the same developers. The new malware is being called “Droid Dream Light” (DDLight). Malware in the tainted apps can be activated by an incoming call, meaning users do not actually have to launch the app to trigger it.
Anyone who downloaded an app on Lookout's list could have their personal information compromised. It is suspected that between 30,000 and 120,000 users were affected by DroidDreamLight.
