Geohot, the iPhone hacking expert who had released popular jailbreaking and unlocking tools like blackra1n, blacksn0w and more has discovered a working exploit for baseband 05.12.01 that was bundled with iPhone OS 3.1.3.
Geohot has tweeted the hash tag of the baseband crash for safekeeping:
d8b50dc95d7906e3ff6155331a534b55d0f6cac1=good. And motorama this weekend!
iHackintosh has also published the conversation between Visnet (iHackintosh reader), Geohot and MuscleNerd:
<visnet_> What does geohot tweet mean?
<%geohot> its my bb exploit for safekeeping
<%Par4doX> geohot: did you turn that over to the dev team or are you doing something with it?
<%geohot> my days of turning things over are done
<%geohot> i hope its different from the one they have
<%geohot> but they prob already have it
<%geohot> its the one i orig wanted to release blacksn0w with
<%Par4doX> it’s still there in the new bb
<%geohot> yep, just checked
<%geohot> but then opted to use xemn since it was public
<Evan> Oo, it carries over from 05.11 to 05.12?
<%geohot> why wouldn’t it, apple doesn’t fix things proactivly
<@MuscleNerd> geohot we prob should figure out a way to know if we have same exploit double blind, otherwise we may release 2 different ones at same time
<%geohot> any suggestions?
<@MuscleNerd> not sure how to do that without making it easy to brute force though
<%geohot> yea, i salted the hash
<@MuscleNerd> hmm maybe if we both hash the stack dump
<@Confucious> Can you two take this out of public sight?
<@MuscleNerd> the stack itself, not the header before it or the registers after it
<Her> muscle: any notice about the exploits are the same ?
<%geohot> we are working on it
<%geohot> cryptography, perfect for people who don’t trust each other
