Hi. I was working on a timer program recently, and I stored the entire contents of the source code on my flashdisk. Unfortunately, While i was using another 'foreign" computer, the antivirus or something nuked my source code silently, and it was only after copying several large files on/off the disk that I noticed my source was missing. I tried data recovery (Recuva/etc) but none of them even detected the files. So all I have left is the release version binary I tried TMG Ripper studio with no success at getting the ripped code to work, but I think that there should be some way of getting at least some working code back ..... The program was made in MASM32 with u…

Looking for a light weight debugging engine API
by genuine_- 4 replies
- 4.5k views
Hey guys, Im looking to see if there is a light weight C/C++ debugging engine api for Windows out there? Something capable of handling BP's and such, nothing fancy, this is for a small PoC tool im working on and was wondering before i decided if i needed to just write a small debugging engine on my own. I am only aware of TitanEngine which has such an interface, but TitanEngine is abit much for this purpose. Thank you.

Hiding window state from itself
by brain- 1 reply
- 7k views
I'm running multiple instances of a gui application at once to dump a list each application maintains in form of a ListControl. I would like the windows to stay minimized but unfortunately they stop updating the ListControl then. I thought if the application doesn't know it's minimized it should keep behaving like it's not. After a bit of research i found that basically the only way to determine if a window is minimized is calling IsIconic or handle WM_SYSCOMMAND and remember till the window is restored. But the application does neither. Then i thought maybe the list is only updated internally (which is the only thing that matters, I don't have to see it) when WM_PAINT me…

Hi Recently i've started a project which requires displaying output as a decimal number in ASCII characters. I've done the Hex value - to - ascii char thing but conversion of the number ... say - 2012 from hex (which is 0x07dc) to a decimal number displayed on the screen (2012) is a bit more difficult. Example : eax == 07dc i want to display in a messagebox the decimal value of eax. how do i make it decimal? Thanks

Hey guys, Small question, I've read the anti-debug reference from Peter Ferrie which goes into detail about tons of anti-debug tricks. Now what I am facing is the following.

Yohoo hord of fans... I'm proud to bring you my mkfpack unpacker. I haven' seen dedicated unpacker for this one, only genetic unpackers that supports it. Nothing special to say, except that unpacked file may contains an extra section containing ICON, GROUP_ICON, VERSION and MANIFEST. I have also included unpacker source code and packer source code in masm for those who are interested... See you soon ... Laurent aka BIGBOSS from COPs mkfpack.zip CPS!UnMkfPack.zip

Coding a packer stub in C++
by rendari- 11 replies
- 19.8k views
Hello all, While I've created packers for Windows before, they've all been in assembler. Right now I'm thinking of how to code a packer stub for windows in C++, and am stuck. Has anyone done this before and have any tips? Have any articles been written about this? I have a couple of ideas on how to do this, but they're all really nasty. One involves building the stub as a DLL, and appending it to the exe as a new section. Set Import Table in PE header to point to the import table of the appended DLL. Also you will need to manually fix all the relocations in the DLLs code section. This might work, but I imagine there would be nasty problems. Option 2 is to have an assemble…

I have an idea for an app, but ultimately I would like to make it possible for people to add functionality to it by means of plugins. It would be like Olly in that respect, except not quite that ambitious. What I would like is for people to be able to add this functionality non-language specific, ie. Iif someone wants to use Delphi or .NET, but I want to program the skeleton in C++, that should be allowed. I have done a lot of thinking about this but I wanted to get another's optinion on the best way to structure the framework before I took the plunge and started coding. I would imagine that provding an API is probably the best bet, but I wanted to make sure I didn't miss…

movzx ecx,byte ptr [ebp+8] mov eax,055555556h imul ecx I can understand what those instructions are doing. For instance if ecx takes the letter 'x', the registers would contain the following: EAX: 0x50 ECX: 0x78 EDX: 0x28 Because 55555556 x 78 = 28000050, the high part goes to EAX and the low part goes to EDX. What I cant understand is how do I replicate this using C or C++, I tried to make a function that multiplies some hex number with 55555556 and keep the high/low byte on another variable. But RE that program doesn't produces the same results as those assembly instructions. Can anyone explain me how to translate those instructions into some HLL? Thank in adva…

Anyone knows how BoxedApp does their packing of .NET PE into PE32 executables? I tried creating process from a PE32 stub exe and then mapping .NET PE into suspended process but it doesn't work - gives ".NET runtime not found error". It works only when the referenced stub is a .NET PE itself. />http://www.security.org.sg/code/loadexe.html My objective is to hide the existence of a .NET PE exe within a PE32 exe and yet able to run and load the Common runtime langauge (.net environment). Thanks for any advice.

Bypass Skype API access control?
by Le Freak- 0 replies
- 6.7k views
Good day, I'm trying to automate some stuff using Skype and it's API (Skype4COM.dll). Everything is fine, however, when you access Skype COM for the first time, then it spits out a dialog like this: So you need to click some dialogs in order to confirm your application to use Skype. So I'm scratching my head, how to bypass this ugly dialog. Seems trivial, but I'm completelly stuck at the moment. I did small investigation with ProcMon - Skype stores confirmed plugin data in C:\Documents and Settings\Username\Application Data\Skype\Skypename\config.xml , however its SHA256 encrypted and unique for each plugin and its location, so, no way to copy and paste the configurat…

Hi all, Story; At a certain stage during as setup (setup.exe) a window is displayed. It says Insert CD2. options; Ok, Cancel I go for the Ok option. Using Spy ++ I see the following; IRP_MJ_CREATE IRP_MJ_QUERY_INFORMATION IRP_MJ_QUERY_VOLUME_INFORMATION IRP_MJ_CLEANUP IRP_MJ_CLOSE so it does a check if cd2 is inserted. Using Olly debug; I see in the windows page Handle 002a0503 Parent 0015056E ID 00000001 Thread Main cls proc 752358F1 Is it possible to put a breakpoint on the ok button, using Olly or IDA? pressing the OK button executes a piece of code, is this easily found? I think I need to manipulate the information struct, telling the cd2 has been inserted. regards, g…

Help with inline assembly using Xcode ide
by ispete_2- 3 replies
- 8.2k views
Being a beginner, I wasn't aware that you could even inline ASM into a c++ program until I checked out this keygen challenge and saw the keygen code written by Reaction: http://forum.tuts4yo...-1/page__st__20 I copied the asm portion of Reaction's code into Visual C++ and it compiled and ran fine. However, I'm trying to use the same code in Xcode on a Macbook Pro running OS X 10.6.8, and I'm getting some errors. I don't know if it's differences in syntax or maybe I need to define some things. I'm attaching a screenshot of the errors with the code. Any help is appreciated!
