Cloakware

Process injection and memory cloaking research library for Windows.

Cloakware catalogs and implements known process injection techniques, memory hiding methods, and provides analysis tools for studying how security products detect these operations. Built for security researchers, red teamers, and detection engineers.

Features

Injection Techniques

• Classic Remote Thread - VirtualAllocEx + WriteProcessMemory + CreateRemoteThread
• APC Injection - QueueUserAPC / NtQueueApcThread / Early Bird variants
• Thread Hijacking - SuspendThread + SetThreadContext + ResumeThread
• Section Injection - NtCreateSection + NtMapViewOfSection shared mapping
• Process Hollowing - Create suspended, unmap, remap with TLS support

Memory Cloaking

• VEH Guard Pages - PAGE_GUARD + Vectored Exception Handler for on-demand reveal
• Timer-Based Cycling - Periodic PAGE_NOACCESS / PAGE_EXECUTE_READ permission flipping
• Module Stomping - Overwrite legitimate DLL .text sections (.NET assembly support)
• PE Header Wiping - Erase MZ/PE/Rich signatures from memory

Analysis Tools

• Memory Scanner - Detect unbacked executable regions, RWX memory, wiped headers, injected threads

Infrastructure

• Direct Syscalls - Bypass ntdll hooks via runtime SSN resolution
• Indirect Syscalls - Jump to ntdll syscall gadgets for clean call stacks
• Process Utilities - Privilege adjustment, process/thread enumeration

Building

mkdir build && cd build
cmake .. -G "Visual Studio 17 2022" -A x64
cmake --build . --config Release

Or with CMake presets:

cmake --preset default
cmake --build --preset release

Usage

# List all available techniques
cloakware list

# Inject shellcode via classic remote thread
cloakware inject classic <pid> <shellcode.bin>

# Inject via APC (early bird variant)
cloakware inject earlybird <pid> <shellcode.bin> <target_exe>

# Scan a process for injected code
cloakware scan <pid>
cloakware scan <pid> --verbose

# Cloak a memory region
cloakware cloak guard <hex_address> <size>
cloakware cloak timer <hex_address> <size>

Library API

#include "inject/classic_inject.h"
#include "cloak/memory_cloak.h"
#include "analysis/memory_scanner.h"

// Inject shellcode
cloakware::inject::InjectOptions opts;
opts.bypassCFG = true;
opts.useSyscall = true;
auto result = cloakware::inject::ClassicInject(pid, shellcode, size, opts);

// Cloak memory
auto& cloak = cloakware::cloak::MemoryCloak::Instance();
cloak.Initialize();
cloak.CloakRegion(address, size, CloakMethod::GuardPage);

// Scan for injections
cloakware::analysis::MemoryScanner scanner;
auto findings = scanner.ScanProcess(pid);
