Hello there, and glad to be here for my first post

I've read inside some good crakz pages that IDA is able to read/trace a main app then show you where flexlm is calulating the codes from a facke licence.
I will be very thanksful if someone could help me to understand better how it's possible.
It's just for understanding and because i find this job veryyy interesting.
Thank you so much and sorry if my question is too newbie

IDA lets you analyze and annotate assembly instructions in the binary. Once you have found the interesting piece (flexlm call in your case) you can debug the app. IDA has a built-in debugger for Windows and will let you put a breakpoint and trace what happens in the code.

Thank you so much **s0larian** what a nice reply ;)
I think it's exactely how you describe the thing.I've read so many pages about that but still need an high professor to teach me .
So you mean it's possible...wowow, a new hope come to me.
It's written somewhere and also as you said, the debugger let you put a breakpoint and wait for the new code
generated by flexlm itself during the code.
Is it really possible ?
This is what i've found :
Voila! At address .4715EC you can see the best part of all FLEXlm code -- license number from license.dat and generated number comparison. That's all. You can have it directly by typing :D DS:71E1B8 or by passing all JNE 471613 with zero flag and wait while FLEXlm converts this binary to text string at .471609

cpage, so what are you asking?

The snippet you provided talks about defeating the mechanism using softice, I think. You cannot blindly follow it. Load the binary into IDA, find the "license checkout" call and then take it from there.

Yes sorry i'm not clear but it's not clear in my mind too
So, Yes the main prog need to be patched and specialy the checkout.
Where can i find help for this part ?
I have a chance if i'm starting from point '0' ? i mean starting to learn IDA.
I know people from here got a very high knowledge and experiences and i hope not hurt you with
that kinds of questions, but who never start from '0 ?
So you talk about sniffing the license checkout.
I made some good research inside my binary file and found a nice strings like ,checkout vendor, checkout features, checkout flags wait....
Any help are welcome
