All right.
So welcome to our hopefully our second to last section of the all mail module.
At this point, we still have crashed our application and we have verified all of the bad characters
that we eliminated before.
This time we're going to look for it's basically an S and alert bypass outer space layer realisation,
which is something that Microsoft implemented to prevent attackers like us from successfully explaining
programs.
So to get around that, there are actually many catches to getting a smaller one.
Everything, including every dialogue, must be compiled of dynamic based options in a lot of people
more than we think actually forget to do that.
Which means one not properly compiled module can make that entire application vulnerable to assault
or bypass.
So I want you to type exclamation point on a modules.
And this is the the column where it's our is.
What we're looking for is.
Anything that is not Islam or death.
Did execution, prevention, coercive structure, etc. Hitler's.
And we find it all the way down here from Iselin at Sea Dot deal.
So now at this point, we need to query this and look for a jump construction.
What we can do is use the Asthma, MSA and Asthma Show.
To hunt down it jumps instruction.
And we figure out it is at the E-4.
So now we have to use this command within the specific dynamic league library to look for a job being
instruction which would allow execution of our cell phone.
Mona finds us.
FFP for.
S.
L.
N.
D.
L.
That's right.
So we found numerous pointers.
And we still need to look for things like.
Anything that does not contain bad characters.
And I think I will take the first one.
Yes, the first one will be adequate because there is no specific structurally such a handler, no ad
especially transition, and most importantly, no bad characters.
So we need to write it in a little Indian format.
This is the exact and remote address within the s o mail of C ideal file, but we need to reverse it
into five that for a 30 58f because it's a little Indian ized and it works by lit by the least significant
bit because first.
So at this point, we can change our buffer.
And then from here see the times 3500 to 6, oh six minus four.
And we can also generate a payload because we know that whatever happens there will land in the seas.
So let's try this one more time and see if we can successfully land in the seeds for the jump into the
spin structure.
If you see something weird like you don't see the rest of the contest now view at a CPU window and then
maximize it like that.
And now you can see the registers.
Then our sense of security of the training courses didn't actually mention that, but I just learned
this from experience.
Again.
Find out where we are and.
Shall PSP.
We land it in the beginning of our buffer.
And what I want you to do now is replace the final shell code because we're ready to finally open this
box.
