This Boo language script demonstrates an alternative method for shellcode execution using Windows desktop enumeration callbacks. The implementation includes XOR encryption for additional obfuscation and leverages the .NET framework through Boo's Python-inspired syntax.

Features

XOR Decryption: Runtime decryption of shellcode using XOR operation
Desktop Enumeration: Utilizes EnumDesktopWindows for execution
Memory Management: Implements proper memory allocation and protection
Callback Implementation: Uses delegate-based callback mechanism

Technical Details

Components

Memory Allocation: Uses VirtualAlloc with PAGE_EXECUTE_READWRITE protection
Desktop Handling: Leverages GetThreadDesktop for current desktop context
Shellcode Processing: Converts MAC-address formatted encrypted bytes to executable code
Execution Method: Implements callback-based execution through desktop window enumeration

Prerequisites

Boo compiler
.NET Framework
Windows environment
Python (for shellcode encryption)

Usage

Encrypt your shellcode using the provided Python script
Insert the encrypted shellcode into the Boo script
Compile and execute the Boo script
