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

## How do I use this?

Please refer to the [Wiki](https://github.com/CPunch/Laika/wiki) for any questions relating to deployment, compilation & setup.
