Armadillo 1.xx - 2.xx -> Silicon Realms Toolworks [Overlay] < Unpackable??????

[MaRKuS-DJM]

paul, this breakpoint on CreateThread happened inside program. you are already deep inside the program. maybe this arma doesn't call CreateThread before OEP (but i've never seen that, maybe custom build) or you set it to late which is impossible. try a hardware-breakpoint or memory-breakpoint on createthread if it breaks

Hi Markus thanks for patience

i tried HE CREATE THREAD but same thing i land same place as before...

Maybe its because it one of those arma apps that u need to enter serial first to get to main waindow?..
i was reading a tut and it said something like you got to bypass that serial bit BEFORE u break on oeP coz your still in arma code?...That tuts for copymem tho and this is just a single process..

I found a old dumper tool that acts like its pausing it at oep..this is info it gives me in command window>>

EntryPoint Found - 4A4389h
Name is KERNEL32.dll
Kernel dll found...
CreateProcess found at address 4BB034h
VirtualAlloc found at address 4BB170h
VirtualProtect found at address 4BB174h
Name is USER32.dll
Name is GDI32.dll
Original OEP bytes read
Infinite loop has been set
IsDebuggerPresent has been patched
Injecting process..
New Memory is at 950000h
Original OEP bytes restored

I dumped the app after this using lord pe from memory and ran imprec

i get 3 modules
??thunk bla >really kernel32
user32
gdi32

the thunk bla is really kernel 32 with 1 invalid
i ran auto trace 1 on invalid and it gave me

1 000BB034 kernel32.dll 0049 CreateProcessA

which left me with the 2 suspects which r both

1 000BB138 kernel32.dll 00C6 FreeEnvironmentStringsA
1 000BB13C kernel32.dll 00C6 FreeEnvironmentStringsA

Leaving the 2 suspect functions in and fixing dump gives me an exe that pops up an error saying the program has been damaged to a bad sector on hard drive or virus please re-install it ??

ta

paul333

that means you didn;t dump it at the right oep.. had that same problem manytimes...

just saw your other post and reconized the app.. i'll give it a go and see if i can get the oep

anyway i came up with the oep as 00452C84 .. but now rebuilding the iat is a different question :'(

Hehe nice on Xastey, ill give it another go later

Thanks

Sorry xastey what breakpoint did you use??

paul333

just bp CreateThread

[bunion]

My settings for FIRST debug STOP must be wrong then as when i use bp create thread or he create thread i stop at what u see in my posts above..in olly options app is set to break when first running on WINMAIN...also tried running it to break on module entry point after first run but still when i bp create thread i dont land near where im supposed to

You sure you have right app xastey?..videoredo?

paul333

Did you rename OllyDBG.exe? Will the app run if you just Hit F9 when a debugger is attached? Kinda wondering if your in Anti-BP code or it detects your debugger. Bp CreateThread is all you need - maybe try looking for Ricardo's OllyDBG config and try using that and doing the Breakpoint he posted a link to it somewhere on the forums.
