+
+Laika is a simple Remote Access Toolkit stack for educational purposes. It allows authenticated communication across a custom protocol with generated key pairs which are embedded into the executable). The bot client supports both Windows & Linux environments, while the shell & CNC server specifically target Linux environments.
+
+![DEMO](https://github.com/CPunch/Laika/raw/main/img/demo.gif)
+
+Some notable features thus far:
+- [X] Lightweight, the bot alone is 270kb (22kb if not statically linked with LibSodium) and uses very little resources minimizing Laika's footprint.
+- [X] Authentication & packet encryption using LibSodium and a predetermined public CNC key.
+- [X] Ability to open shells remotely on the victim's machine.
+- [ ] Ability to relay socket connections to/from the victim's machine.
+- [ ] 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
+
+## Configuration and compilation
+
+Make sure you have the following libraries and tools installed:
+- CMake (>=3.10)
+- Compiler with C11 support (GCC >= 4.7, Clang >= 3.1, etc.)
+
+The only dependency (LibSodium) is vender'd and statically compiled against the `/lib`. This should be kept up-to-date against stable and security related updates to LibSodium.
+
+First, compile the target normally
+
+```sh
+$ cmake -B build && cmake --build build
+```
+
+Now, generate your custom key pair using `genKey`
+
+```sh
+$ ./bin/genKey
+```
+
+Next, rerun cmake, but passing your public and private keypairs
+
+```sh
+$ rm -rf build &&\
+    cmake -B build -DLAIKA_PUBKEY=997d026d1c65deb6c30468525132be4ea44116d6f194c142347b67ee73d18814 -DLAIKA_PRIVKEY=1dbd33962f1e170d1e745c6d3e19175049b5616822fac2fa3535d7477957a841 -DCMAKE_BUILD_TYPE=MinSizeRel &&\
+    cmake --build build
+```
+
+Output binaries are put in the `./bin` folder
