Jailbreaking an iPhone gives you the freedom to run the apps and interfaces you want (rather than those allowed by Apple), but it also carries some inherent risks -- you're giving apps much more control over your phone. And unfortunately, some of these users are discovering this the hard way. Researchers have discovered a strain of iOS malware, nicknamed KeyRaider, that has stolen over 225,000 Apple IDs from jailbroken devices. The software takes advantage of Chinese app repositories that let people directly upload and share their own titles. If you happen to download the code, it'll either scoop up your Apple account data (to give rogue users "free" apps) or hold your phone for ransom.
