Scylla IAT fix functions as DLL/Lib 1 2
by cypher- 27 replies
- 22k views
Hey there, as the available Scylla DLL by Aguila only supports dumping and I needed a good IAT fixing DLL/Lib, I made a wrapper around the Scylla source. Also because the available ImpRec DLL isnt such as easy to use as I wished. Check out the source on BitBucket https://bitbucket.org/cypherpunk/scylla_wrapper_dll or grab attached binaries: Debug x86 Release x86 Debug x64 Release x64 Its based on latest Scylla source. Basically it mimics all steps you do in the GUI version but also offers more detailed control if you need it. Features: IAT AutoSearch reading Imports validating Imports cutting Imports (if the corresponding module would be empty, its cut too…

I'm currently working on Scylla and I want to implement a direct import scanner. It would be nice if we could collect the different direct import implementations of protectors. For example: eXPressor ------------- 5 byte CALL 0xFFFFFFFF + 1 byte bogus value Themida/Winlicense ------------- 5 byte JMP 0xFFFFFFFF + 1 byte bogus value are there any more?

In short. Target have been protected with Armadillo 9.60 custom build. Protection options: 1. DebugBlocker 2. CodeSplicing 3. Iat Elimination I made a video of the problem. From the video i skipped the unpacking process and i'm at the OEP with DebugBlocker passed, IAT fixed, Splices removed. When i try to dump and fix with Scylla i get a nonworking dump (same with ImpRec) but when i try to fix with ImportsFixer the dump is running fine. Here is the video and the packed file. I have wondered many times what could be wrong...what i have failed to do... but in a apotheotic end was the dumping tool. Hope to get a solution for this problem. Scy…

I found a solution to create single binary that works as dll and exe. I don't know if there are any side effects. Somebody has a better solution? This is the entrypoint function: extern "C" BOOL WINAPI _CRT_INIT(HINSTANCE HinstDLL, DWORD FdwReason, LPVOID LpReserved);BOOL WINAPI DllEntryPoint(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpReserved) { if ((fdwReason == DLL_PROCESS_ATTACH && lpReserved == NULL) || fdwReason == DLL_THREAD_ATTACH) { if (!_CRT_INIT(hinstDLL, fdwReason, lpReserved)) { return(FALSE); } } else if ((fdwReason == DLL_PROCESS_DETACH && lpReserved == NULL) || fdwReason == DLL_THREAD_DETACH) { if (!_CRT_INIT(hinstDLL, fdwReason, lpRese…

bug in "pick dll" operation
by nullRd- 7 replies

To see this bug yourself - grab any process (e.g. firefox.exe), then press "pick DLL" button. Then choose any module (e.g. kernel32.dll) Now press "IAT Autosearch" and "Get Imports". This is what I've got: 1. picked module - kernel32.dll 2. resolved imports are still belongs to main module... 3. ..but their RVA is calculated relative to base of selected module!bug tested on XPSP3, W7x64 Scylla ver 0.9.1 x32, x64

What new features do you like/need in a such a tool. My plan is: - code scanner (e.g. find direct apis) - better dump engine - save/load import tree - GUI improvements - improve IAT Search - Some Options + options dialog - ImpREC plugin support Things I won't implement: - Hexeditor (Winhex, HxD) - PE Editor (CFF Explorer is perfect)

Scylla Launcher
by mrexodia- 7 replies
- 7.6k views
Hi, For personal use I created a small launcher program that allows you to quickly select if you want to start Scylla_x86.exe or Scylla_x64.exe. This was useful in my case because I assign hotkeys to tools, which means that I should've assigned two hotkeys to scylla instead of one. Program+sources attached, please consider adding it to the official release, maybe more people have benefit from it. Screenshot: Greetings, Mr. eXoDia Scylla_Launcher.rar

First of all: Thank you for that awsome project and making it open source! Second: In case anone has the same problem while trying to compile Scally Imports Reconstruction here are some hints: For x86 VisualStudio10: Follow instructions in Scylla\README-WTL additionally: set Platformtoolset to v100 instead of v90 for all 3 projects Download distorm.package3.1 and unpack it in the diStorm directory. Open diStorm\include\distorm.h and comment line 40 (#define SUPPORT_64BIT_OFFSET) to disable it (else i got linker errors) in "Linker --> Input -->additional Dependencies" add: psapi.lib and Imagehlp.lib Now to main part of my post: Imagine you have a IAT that…

Scylla + Overlapped Headers
by waliedassar- 8 replies
- 12.1k views
If you try to FIX DUMP an executable with the IMAGE_NT_HEADERS structure overlapping the IMAGE_DOS_HEADER i.e. the e_lfanew field has a value less than or equal to 0x38 (and of course, greater than or equal to 0x2), the resulting executable is rejected by the windows PE loader. http://uploadpic.org...p?img=BdtSYOk9l This is due to Scylla moving the IMAGE_NT_HEADERS at offset 0x40 without updating the "e_lfanew" field. This was tested with Scylla v0.7 beta 7. Best Regards Waliedassar
