Last October privacy and security technology experts were buzzing about the launch of Firesheep, a Firefox extension that gave hackers the ability to easily hijack unencrypted Facebook, Twitter, and even Amazon credentials from other users on the same wifi network. The same individuals who were concerned about Firesheep are probably just as scared about FaceNiff, an Android application that launched last week from Polish developer Bartosz Ponurkiewicz.
Security researcher ‘Ms. Smith’ on NetworkWorld, calls the app a “wicked mobile cousin of Firesheep.” With a rooted Android phone, a user can run FaceNiff to sniff and intercept web session profiles over wifi connections to hijack credentials from Facebook, Twitter, YouTube and other services.
Now a hacker doesn’t even have to go through the hassle of opening a laptop, as was required with Firesheep; he can simply use his mobile device. Using the application is as straightforward as sending a text message from your Android phone. Check out this video to see the app in action.
So not only does FaceNiff bring the security implications of Firesheep to the more accessible mobile sphere, but it also goes one step further. With Firesheep, if a user is on a password-protected WEP, WPA or WPA2 secured WiFi network, he cannot be hijacked. But with FaceNiff it doesn’t matter; all networks – secured or unsecured – are vulnerable to attack.
Protect Yourself From FaceNiff
Many technology and security experts are concerned and strongly encourage users to connect to WiFi networks with caution. Rosa Golijan from MSNBC’s GadgetBox asks her readers, “Do you trust whoever set up the network you’re logging on to? Do you even know who runs it? Think twice about using free public networks.”
But if you find yourself on a network and you doubt its security, Mashable recommends using HTTPS for an extra level of protection. However, as PRIVATE WiFi™ has reported in the past, while HTTPS is better than HTTP it is still vulnerable to man-in-the-middle attacks.
Thus, we recommend, just as Mobile Magazine, to protect yourself with a Virtual Private Network (VPN) like PRIVATE WiFi to encrypt your online traffic. That makes your logins and your Internet communication invisible to sidejackers and hackers, even when using vulnerable websites. If the user in the above video would have been running PRIVATE WiFi on his computer, FaceNiff would have never detected him!
Does the idea of FaceNiff being able to hijack your log-in credentials leave you feeling vulnerable? Would you download PRIVATE WiFi to guarantee your privacy and security on the internet?
