Stefan Esser aka i0n1c, a security researcher and a person behind the untethered jailbreak for iOS 4.3.2, says someone close to evad3rs may have stolen a jailbreak exploit and sold it to an unknown private buyer.
As to the members of the evad3rs team, they deny such a theft. Moreover, they note that “the jailbreak stuff is moving on, but slowly.” That means that we won’t see it until 2014.
Even if the a jailbreak was stolen from the evad3rs and sold to a private buyer, it’s unlikely that the buyer would be looking to share it with Apple. However, if a jailbroken device is found in the wild, Apple could examine it to close the vulnerabilities for future firmware versions.
Let’s hope nobody has stolen the jailbreak exploit.
