What happens if I change the value of Elf version number?
We know elf has only one version, right?
And which is version?
One.
What happens if I change it to two?
Let's verify.
So I'll use hex editor and I know where it is present.
It is present uh, here which is 0123456.
I'll change it as different number.
Let's say five.
Let's save this.
And now let's verify.
It is, it has changed to data.
So it's a mistake for my send and it will change it here and I will save this now.
Version is saying five.
It is saying unknown.
Which is what, because we only have one version.
That's the reason it is saying five unknown.
So you can make modifications to all these bytes and check what happens when you run the PDF.
