how to make my own cracks

[cdkiller]

i know that everyone wants to crack safedisc / securom etc...
but start simple, read tutorials about cd-checks / nag-screens

if u can handle the different kinds of CD-Checks
(GetDriveTypeA, GetVolumeInformationA, GetLogicalDriveStrings)
than i recommand u to try unpacking with softice / ollydebug.
download some crackmes und read the included tutorials.

what u need:
-----------------
- a brain, as always
- pen and paper (in case of reboots and hints etc...)
- Tutorials as many as possible
- ASM / Win32APi knowledge (focus on TASM language)
- Win32Dasm or IDA to disassemble an exe/dll
- HexEditor (i prefer HexWorkShop and HView)
- a debugger like SOFTiCE or OLLYDEBUG and the references

beginner should start with this site, coz the tutorials are easy to understand and cover 'how to remove cd-checks'

u forgot the all important pen and paper

/me slaps cdkiller

and tasm and masm arent really that far apart.. try making an anti debug kmd in tasm.. i wish you luck

[cdkiller]

lol, i doubt a cracking newbie can code anti debug stuff

how could i forget pen and paper
/me is confused coz of the slap

[TippeX]

i slapped ya to make u remember the all important pen and paper next time

you also forgot the other things

- an rva is not an offset
- patch the proc not the conditional
- remember that proc returns are passed via eax which is trashed on your next api call (couldnt resist) ;pp

ok..
I been playing with the Cycling Manager 3 update, I managed to hook into this prodrv04.sys driver and made it ignore the cd in the drive. Now I still need to unpack the executable though, how do you suggest I proceed?

[TippeX]

really?

lol do u talk about me ??? i think about the regsetup.exe

You also might need Windows 98 as the Platform/OS!

nope win98 is due to be phased out soon, and will not be supported anymore, so you're gonna have to start cracking in 2k/xp etc.. which is only a little bit different

[krondike]

As I heard from CDKiLLER and as it was my point... the best OS to start doing crack in, is Windows 98.

But if microsoft are gonna start to stop with servive...maybe cracking tools are gonna fit for NT based system...

[cdkiller]

Win98 is really outdated
i´m on WinXP and Win2k Pro...

use Compuware.SoftICE.Driver.Suite.v3.0
it´s WinXP compatible.

[TippeX]

heh 3.0.. you're better off using 2.7 considering that 3.0 doesnt allow global bpx's, only context ones.. compuware kinda took a step backwards in that one

[ByteMare]

heh, guess some "big companies" got pissed off by ppl using bpx's to tamper with their software... Ahh, just kidding..

Can a Trial version be found somewhere?

[TippeX]

i think theres a 14 day trial kicking about, dont know if its crippled or whatever (the 3.0 installer will install as 14 day demo if you dont supply a key)...try the compuware site i guess although i would you recommend you learn your assembly code before you start playing with softice
