iOS jailbreaks and exploits--
now, this terminology can be slightly confusing,
and I strongly recommend that you become familiar with it.
And I'm going to talk more about this in Section 3.
Checkra1n and checkm8-- so checkra1n
was the first jailbreak that supported the checkm8 exploit.
Now where this gets confusing-- it's so easy for me
to say to you checkm8 is the exploit
that was detected by axi0mX on the chip of iOS devices.
This was a rude awakening for Apple users.
So if you think about this, Apple is supposed to be secure.
The chip in the iPhone and iPads were
susceptible to being jailbroken and getting a full file system
acquisition of it.
It is fantastic forensically.
It's terrifying when you think about your device falling
into the wrong hands.
Cellebrite uses the term checkm8 to run checkra1n.
So this is where this is a little bit confusing.
So be careful with this terminology.
So what I want you to remember is checkm8 is the exploit.
This is the flaw on the chip.
Checkra1n was the first public jailbreak release
that provided full file system access.
This was amazing when we look at this.
I'm going to discuss Cydia.
I'm going to discuss AFC2.
I'm going to discuss how the tools leverage this more
in Section 3 as it pertains.
But this is a point where we have
to talk about it because we just talked
about all the additional ways we can access data from Android,
so now we need to consider these ways of accessing
more data on iOS devices.
