Module contents

The covertutils module provides ready plug-n-play tools for Remote Code Execution Agent programming. Features like chunking, encryption, data identification are all handled transparently by its classes. The SimpleOrchestrator handles all data manipulation, and the Handlers.BaseHandler derivative classes handle the agent’s and handler’s actions and responses.

The module does not provide networking functionalities. All networking has to be wrapped by two functions (a sender and a receiver functions) and Handlers will use those for raw_data.
