IOS 14.2 (using 13.3. SDK) having ran around for a few hours trying to figure out how to write some code on the iPhone I decided to quickly sum up a few snafus I ran into on various message boards Yes theos works and if you follow the theos install tutorial on their dev site there shouldn't be problems with theos except your Makefile should contain if using the below referenced private iOS 13 SDK (I had unzipped the SDK-master into theos sdks folder then unzipped the iPhone13.3.sdk) so the below sysroot line is different than what you may decide to do ARCH = arm64 SDKVERSION = 13.3 SYSROOT = /var/opt/theos/sdks/iOS13-Private-SDK-master/sdks/iPhoneOS13.3…

Hello, Can you convert this cmd code to Disassembly code, thank you. taskkill /IM notepad.exe /F

I am developing hidden vnc on windows in c++ language. I am going to connect vnc keyborad and mouse event to controlled pc. But I don't know how to send key and mouse event to certain vnc server thread. I have searched in google for a long time, but I don't have usefull information. I only know that I have to use below windows api. CreateDesktop OpenInputDesktop SwitchDesktop I'll appreciate any help.

i am working on a confuserex mod and i'm a beginner so i doubt it's very good but i am trying to find a way to make my mod create a custom class while obfuscating called "Program.cs", i'm clueless on how to do this and appreciate any help. thanks

c# code like this: string str = "MyString"; What is the meaning of each area in memory as below?

I'm trying to write my own PE reader and would like to get the size of an export function. But this information is not provided in the export directory of the PE header. How can I get the size? This must be possible somehow, for exampled dbghelp knows where the function starts and ends. I have the same problem when trying to parse a PDB file. I can get the actual offset of the public symbol but not its size. Any ideas?

Hi there. I am looking for another v2m player that uses this kind of version of libv2 , because the V2M player from MagicH uses only libv2 1.0 (which he made it work for vista and later) and i saw some assembly source code that uses libv2 1.5 on a THETA NFO viewer 2.2 , so i'm gonna post a part of the code where the libv2 is initiated and loaded in asm : include ./Music/libv2simple.inc includelib ./Music/libv2simple.lib externdef c theTune:byte externdef c theTune2:byte include winmm.inc includelib winmm.lib DlgProc : ; libv2 music start invoke V2MInit,offset theTune,FUNC(GetForegroundWindow) invoke V2MPlay; anyone has this library for asm p…

Hi guys , it is been a while that i am try to understand how PE files . I did some research and experiment that i will write about them here , but lots of thing does not make sense to me. So C++ codes are already too much complicate to start with , so i decided to compile a pure 64bit assembly code using visual studio 2019 , the code is as follow : .data MorphByte db 78 Morphling db 68 Death db 44 .code main proc xor rax, rax mov rbx, 456 mov rcx, 666 mov rax, 123 add rax, rbx xor rbx, rbx lea rax, [rcx] mov al, byte ptr [MorphByte] ret main endp end now , after compiling the above code we will get two files one .exe and one .obj , since my code is …

I'm currently building software using ASIO as a network library and its SSL counterpart. It has worked perfectly, but I've recently tried to initialize the context in a manually mapped DLL and SSL_CTX_new is failing when ASIO initializes it's OpenSSL components. The odd thing is that no error can be resolved from SSL_CTX_new's failure, it simply returns error code 0. So, I dug into the code and I believe I've dumbed down the failure to OPENSSL_init_crypto. The only problem I can think of is TLS (Thread Local Storage). I've handled TLS manually, and TLS seems to be fixed, but the problem persists. Note the code works perfectly when the DLL is loaded via LoadLibra…

Hi I have an executable .net application and how to hook Microsoft.VisualBasic.CompilerServices.Conversions.ToString(long Value) for logging Value ? thanks

Run Constructor even Activator.CreateInstance gives Exception Assembly asm = Assembly.LoadFrom(@"X:\xxxasd.exe"); Type kd = asm.GetType("keydata"); // Create an instance of the type object classInstance = Activator.CreateInstance(keydata, null); ----------> This always throws errorr ..tried different approaches i.e with other parameters and Bindingflags ... There is also System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor(RuntimeTypeHandle type), which additionally guarantees that the static constructor is only called once, regardless how many times the method is called: Type myClass = typeof(MyClass); System.Runtime.CompilerS…

Create Instance without calling constructor FormatterServices.GetUninitializedObject() will create an instance without calling a constructor. I found this class by using Reflector and digging through some of the core .Net serialization classes. using System; using System.Reflection; using System.Runtime.Serialization; namespace NoConstructorThingy { class Program { static void Main() { // does not call ctor var myClass = (MyClass)FormatterServices.GetUninitializedObject(typeof(MyClass)); Console.WriteLine(myClass.One); // writes "0", constructor not called Console.WriteLine(myClass.T…

HI i want to make Context Menu for my tools like New Context Menu in picture or 7-zip or Winrar i readed a topic for that and i know i must use c++ to make it but i can't do it any one has tutorial to do it or explain how THX

Hello guys. Your forum is great and very helpful! Thanks for your work! I am a beginner in reverse engineering with some basic knowledge of C++. I wanted to create a small offset patch in c++. I found a simple template on how to do that. I tried it first with a simple NOP patching and it worked. After I edited it to patch 8 offsets I ended up with a not working-Send report to Microsoft application. I uploaded the edited source code. I don't know much about it, and why that happened. . . Is this the proper way to do it? Is there another better template? I know that there exist some cool patch engines but I would like to experiment and building my own. Thanks in advance! …

There is an interesting tool called Unlinker It includes an example lzo.obj file. However I have no idea how to and use .obj file in VS. I added obj into additional dependencies, which works fine and project compiles but how can I call its functions?

A self-contained C# game in 8 kB (nice article) This repo is a complement to my article on building an 8 kB self-contained game in C#. By self-contained I mean this 8 kB C# game binary doesn't need a .NET runtime to work. See the article on how that's done. The project files and scripts in this repo build the same game (Snake clone) in several different configurations, each with a different size of the output. https://github.com/MichalStrehovsky/SeeSharpSnake

Hello. I'm using KOL - Key Objects Library. How to implement in the program, there is a Toolbar with buttons and a form with a paintbox. Is it possible to do the following when pressing the button on the icon appeared the cursor as in DragAndDrop and after the picture was drawn on the paintbox. That is, it is not necessarily true DragandDrop. It is possible to confine only to changing the type of cursor. https://yadi.sk/i/6ovsPsZyIGxvGQ among those represented in KOL_ansi.inc there is none. const IDC_ARROW = MakeIntResource (32512); IDC_IBEAM = MakeIntResource (32513); IDC_WAIT = MakeIntResource (32514); IDC_CROSS = MakeIntResource (32515); …

hey there all. whenever i try to add a v2m file on masm32 (with a V2m player from magic_h2001, include file + library), i get an error saying: LINK : fatal error LNK1104: cannot open file "OLDNAMES.lib" how do i fix this problem?

Hey guys, I am just learning the Mono.Cecil and trying to write a simple string decrypter / junk code remover and I have a couple of questions. The methods that are added from the obfuscator are duplicated. Loop through the modules and remove the junk I only remove the junk from one instance. My first question how would I go about updating the token of the other methods to be the method with the junk code removed or what is the best practise for fixing this? The other question is what is the best way to loop through and remove IL code from a binary. I am currently using NOP to remove the junk code (Line 98-106) but when I use mDef.Body.Instructi…

messing around with some code done by H0mbre at https://h0mbre.github.io/HEVD_Stackoverflow_SMEP_Bypass_64bit/ thought i'd put this on the tuts4you walls to obtain ntoskrnl location using undocumented RtlGetNativeSystemInformation #include <windows.h> #include <iostream> using namespace std; FARPROC proc; HMODULE hdll; LONG* ntos; WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { hdll = LoadLibrary("ntdll"); proc = GetProcAddress(hdll,"RtlGetNativeSystemInformation"); VirtualAlloc(NULL,0x1000,0x3000,0x40); asm ( "mov rcx,0x0b\r\n" "mov rdx,rax\r\n" "mov r8,0x1000\r\n" "mov r9,rbp\r\n" ); proc(); asm (…

So I've become very interested in the entire deobfuscation-topic, and I was wondering what is actually the most efficient way to implement e.g. constant-folding for disassembled obfuscated binary data, or maybe some kind of instruction-reduction algorithm. By efficient, I obviously mean which would have the greatest impact and work best in reversing e.g. instruction expansion. My current thoughts are whether it would be most efficient to write an IR-structure for a standard x86 instruction, which exposes data from the instruction operands, etc. and run for example a loop through a container of instructions to try and collapse some of them in a smart manner, or check …
