Published iBoot source code said to be the biggest leak in Apple history

Remember last July when Apple pushed out firmware for its HomePod smart speaker to developers, and it revealed leaks about the iPhone X? Only back then, we were calling the device the Apple iPhone 8, as were all media outlets at the time. That leak gave us our first look at the infamous "notch" and showed us that without Touch ID on front, a facial recognition system seemed likely (which was something that KGI Securities analyst Ming-Chi Kuo had amazingly told us five months earlier).

That leak might have been surpassed by what some are calling "The biggest leak in Apple history." Apparently, the iBoot source code has been published. As you might be able to tell from the name, this is the code that loads iOS on Apple's mobile devices. The iBoot source code ended up on software development platform GitHub, which could allow hackers, researchers and others to find the spots to attack in iOS. It could help those with malicious intent to decrypt an iPhone. And while the leaked iBoot code is from iOS 9, odds are that some of the published information remains in use on iOS 11.

Possibly confirming the relevance of the leaked code, Apple filed a copyright takedown request with GitHub, and the iBoot code was taken down, but not before it was posted for many to see. Before the code was removed, author Jonathan Levin, who has written books on iOS and Mac OSX, said "It’s a huge deal." He also noted that it matches code that he had previously reverse engineered. Another researcher also said that he believes that the code is legit.

Bet any money that nothing major will come out of it. It’s over two years old. I’m prettt sure they made changes.

I wouldn't rush to bet. Apple has a history of lame security in its os. There might be bugs they haven't discovered yet.It's only a matter of time before someone takes advantage of it. Remember celebrity nude leaks, mac "root" issue and here's the flaw they didn't notice for 18 months

“I wouldn't rush to bet. Apple has a history of lame security in its os.“ Really? Compared to what?

Well, until a few weeks ago you could gain admin acess on a Mac by using an empty password. So...compared to pretty much anything :)

That would’ve helped if I asked for an example. But I asked compared to what.

The celebrity nude leak wasn't a hack or exploit, but just password guessing. The Mac root and SSL bug were major, but to say Apple has a history of lame security is just exaggerating.

I am apple guy so as much as i wish you were right, you are not ios 11 is not a major overhaul so it wouldn’t be build from ground up. Almost 50-70% would have been same and just the part that would have been the essential for incremental updates to work would be changed. No company wants to waste resources on same thing which they have done already which could be spend on new things and so they just keep stacking them on old things.

Apple should release the whole iOS with Source Code like Google AOSP so us poor souls could experience the fluid iOS for a change! Would love to try something new on my S6! Getting a little bored with The Samsung Experience UI. Now thinking about flashing the ROM with something else. Something different and a little more basic. Something stock. I hear promising things about Lineage OS based on Oreo. Heard its pretty darn stable. Never flashed a ROM before so I'm a tad overwrought on the idea. Don't want to brick my $200 something phone! Besides, I'm much too old for that geeky mambo-jumbo stuff and will surely forget something and bobble-up everything! What do you say, eh? Take the risk or just live with it? Oh well, G'Day!

Installing roms are comparatively easy on samsung then say sony or htc. If you follow step by step video from youtube, it shouldn’t take you more then 15min to install a rom (rooting included) and s6 being 2 year old would have lots of 3rd party reasonably stable rom by now. ps: Bricking a device is kinda hard unless you have a very bad luck.

Nothing will come of it, this code has been floating around the net since 2016. The only reason it's getting media attention is that it was posted to GitHub and Apple issued the takedown notice. Anybody that wants the code already has it and has had it for quite a while.

Its 2 years old explore, so come on people give Apple the benifit of the doubt that they fixed it. However I will be on here rip Apple if they didn’t fix after it go public.
