Jailbroken iPhone gets Dangerous Worm - No Rickroll here
Having a jailbroken iPhone has its advantages, but now it seems like it's going to have some huge disadvantages. We posted on the last worm that affected the phone - a small time prank dealing with the "Rick Roll". This time, though, it's not something to laugh about. The new worm, which works a bit like PC botnet's, digs its way onto your device by use of Wi-Fi and 3G connections, and singles your phone out for the attacker - wherever they are. From there, they can do all kinds of things to you, but the specifics elude me.
At the moment the only known way to protect yourself is to un-jailbreak your phone, and downloaded Apple's latest firmware. Sometimes safety comes at sacrifice it would seem.
