Curb your enthusiasm, jailbreak devotees; downloading Evasi0n, the new iOS 7 jailbreak, could be dangerous. Developed by Evad3rs, this jailbreak includes hidden code from a third-party Chinese vendor that resists any analysis and tampering. In a recent blog post, Lookout explains why you might not want to download Evasi0n.
Jailbreaking your Apple device cuts the ties your gadget has with the big company. The software you download exploits a software flaw in the device's system, allowing root access to and removing limitations that Apple imposed on devices running its iOS operating system.
While jailbreaking can be useful to change user interface and unlock carrier-locked phones, it comes at a cost. A jailbreak compromises a phone's innate security defenses, leaving your device vulnerable to attacks.
Evasi0n for iOS 7 includes an obscured Chinese code within the installer that examines the language setting of the Mac or PC running it. If the device's language is set to Chinese, the jailbreak installs Taiji, a third party Chinese market, on the target phone. If not, it installs the "Cydia" app store.
After the Taiji Market is installed, it disables any other jailbreak community markets and resists attempts to remove it. Keep in mind that at this point the Taiji Market has full privileged access to the user's device, allowing the operators to do whatever they want with it, including hijacking data or remotely controlling the device.
If you want to jailbreak your device, make sure you understand all the security risks that come with that decision. You should backup your device before trying to jailbreak it as well in case something goes wrong.
Be sure to only install apps from trusted stores and make sure you're protected against drive-by downloads or dropped apps. iOS devices automatically prevent drive-by downloads unless you jailbreak your phone. Jailbreaking has its perks, but it's important to be aware of some of its risks.
