Jailbreaking

 

Rooting your device to allow the installation of software that has not been verified by vendors or made available in official app stores has security ramifications. You may not only invalidate your warranty but also open up your device to malware, malicious apps, and data theft.

An example of this is KeyRaider, a malicious campaign uncovered by Palo Alto Networks in 2015. The malware specifically targeted jailbroken iOS devices, leading to the theft of 225,000 Apple accounts and their passwords. A new iOS jailbreak method was released in May.
