What do you mean? Can you show some screenshot how do you add custom anti-tamper? The difference I can see is: The anti-tamper method is called by EntryPoint in your target, but it's called by ::.cctor in standard .NET Reactor.

If its not on the build you're using, I am assuming its coming in the near future.

@Visual Studio How do you add custom anti-tamper? Can we add custom anti-tamper on .net reactor 7.5?

Took a quick look, didn’t dive too deep yet. Already managed to expose part of the check (PBKDF2 → AES → "UNPACKED"), so it’s not as opaque as it first looks. This kind of protection layer is also something I’ve been dealing with in my own work: https://forum.tuts4you.com/topic/46002-continuation-fork-krypton-net-reactor-devirtualizer/#comment-229109 No full unpack yet, just a quick peek for now.

.NET Reactor v7.5.9.1 (Aggressive Settings + Custom Anti-Tamper) Hey everyone, I put together a small challenge for anyone interested in reversing .NET protections. This one is packed using .NET Reactor v7.5.9.1 with some pretty aggressive settings, along with a bit of custom anti-tamper logic on top. Your goal is to unpack the application and recover a clean, working assembly. Protections Enabled NecroBit String Encryption Obfuscation Anti ILDASM Hide Method Calls Code Virtualization Anti Tampering Anti Debug Merge Enums Control Flow Obfuscation (Level 9) Additional Protections Custom runtime anti-debug Anti-injection checks Integrity verification A background watchdog thread 🎯 Objectives 1. Primary: Unpack the application and produce a clean assembly that runs without errors 2. Bonus: Recover the correct password (completely optional) File Information Submitter Visual Studio Submitted 04/13/2026 Category UnPackMe (.NET) View File

Getting real version number of Windows 8.1

Sun, 12 Apr 2026 01:16:45 +0000

Thanks. Your example works, but in my Visual C++ program RtlGetVersion doesn't work, probability I'm missing some config. I was able to fix this by @boot samples; all works fine now.

I have very big progress on solving nuitka but I also realized how impossible it is to good reverser. Also I changed link so you can look from previous folder of nuitka_blob_loader.

char* version_str = TryReadRegistryKey(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "CurrentVersion"); // CurrentVersion" if (version_str!=0&&((finded = strstr(version_str,".")) != NULL)) // doesn't work in Windows 8.1 neither on Windows 10. RTL_OSVERSIONINFOW rovi = { 0 }; HMODULE hMod = ::GetModuleHandleW(L"ntdll.dll"); if (hMod) { RtlGetVersionPtr fxPtr = (RtlGetVersionPtr)::GetProcAddress(hMod, "RtlGetVersion"); if (fxPtr != NULL) { rovi.dwOSVersionInfoSize = sizeof(rovi); if ( STATUS_SUCCESS == fxPtr(&rovi) ) { OSVERSIONINFO os; ZeroMemory(&os, sizeof(OSVERSIONINFO)); os.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); os.dwMajorVersion = rovi.dwMajorVersion; os.dwMinorVersion = rovi.dwMinorVersion; return os; } } } // doesn't work in Windows 8.1 neither on Windows 10. PPEB2 pPeb = NtCurrentPeb(); if (pPeb!=NULL) { OSVERSIONINFO os; ZeroMemory(&os, sizeof(OSVERSIONINFO)); os.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); os.dwMajorVersion = pPeb->OSMajorVersion; os.dwMinorVersion = pPeb->OSMinorVersion; return os; } // works on all versions of Windows including Windows XP; Windows 8.1, Windows 10, Windows 11. char* majorv_str = TryReadRegistryKey(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "CurrentMajorVersionNumber"); // Works on Windows 10 and Windows 11.So RtlGetVersion doesn't work on Windows 8.1 neither TryReadRegistryKey(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "CurrentVersion"); "CurrentVersion" seems to be virtualized. So I will use TryReadRegistryKey(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "CurrentMajorVersionNumber"); and if fails PPEB2 pPeb = NtCurrentPeb(); from now. Thank you @boot
