Laika

Laika is a simple cross-platform Remote Access Toolkit stack for educational purposes. It allows encrypted communication across a custom binary protocol. The bot client supports both Windows & Linux environments, while the shell & CNC server specifically target Linux environments. Laika is meant to be small and discreet, Laika believes in hiding in plain sight.

Some notable features thus far:

• Lightweight, the bot alone is 183kb (MinSizeRel) and uses very little resources minimizing Laika's footprint.
• Authentication & packet encryption using LibSodium and a predetermined public CNC key. (generated with bin/genKey)
• Server and Shell configuration through .ini files.
• Ability to open shells remotely on the victim's machine.
• Persistence across reboot: (toggled with -DLAIKA_PERSISTENCE=On)
  • Persistence via Cron on Linux-based systems.
  • Persistence via Windows Registry.
• Uses obfuscation techniques also seen in the wild (string obfuscation, tiny VMs executing sensitive operations, etc.)
• Simple configuration using CMake:
  • Setting keypairs (-DLAIKA_PUBKEY=? -DLAIKA_PRIVKEY=?, etc.)
  • Obfuscation modes

Why?

I started this project to practice my systems programming skills, specifically networking related things. The networking code in this project (under /lib) is probably what I'm most proud of in this project. After that I start trying to learn some common obfuscation methods I've seen used in the wild. I've used this project mostly to improve my skills of managing a 'larger' project. Things relating to having a consistent code style, documenting features and development tasks are really important skills to have when managing a codebase like this.
