Team UnthreadedJB recently claimed access to a working untethered jailbreak for iOS 6.1.3/6.1.4 on newer devices such as iPhone 5 and iPhone 4/4S. The same hacker group had earlier grabbed the spotlight for their exploits with first ever untethered jailbreak for older iPhones, iPads and iPod touches running on iOS 5.1.1 or earlier.
The untethered jailbreak release for iOS 6.1.3/6.1.4 gains precedence, as the advent of iOS 6.1.3 killed evasi0n jailbreak by patching up all known exploits. Apple's iOS 7 release is just around the corner, and rumours of iOS 6.1.3 untethered jailbreak development gains momentum, as news of iOS hacker winocm claiming access to iOS 6.1.3 untether exploit via binary surfaces online.
Contrary to UnthreadedJB's claims, renowned iOS hacker and evad3rs member, planetbeing, had this to say in his recent Reddit message:
"This code appears to be largely copied wholesale from the private Absinthe 2.0 repository that people involved in the creation of Absinthe 2.0 had access to. These files all originally had a "Copyright (C) 2010 Chronic-Dev Team" line above all other copyright statements.
"Since posixninja created the skeleton project for most of the files, his name is on most of these files.
"Of course, jailbreak.c in the project had to be significantly altered by UnthreadedJB to use the exploitation path used in evasi0n. posixninja did not have access to this code, nor did anyone who conceivably would have given the code to UnthreadedJB. However, making this change could have quite straightforwardly been performed with a machine decompiler such as HexRays."
Given planetbeing's Reddit statement, it is clear that the stolen repo code was not created by either pod2g or planetbeing that offers exploits.
It is not yet known who offered this code to UnthreadedJB team or its source. However, it is ascertained that the new jailbreaking utility, UnthreadedRa1n, uses the same SHAtter's source code created by pod2g.
In other words, it seems some hackers have been illegitimately borrowing or copying hacking programs or tools from jailbreak developers for faking previous iOS jailbreak releases to extort money from unsuspecting users.
