AzureC2Relay is an Azure Function that serves as a validation and relay mechanism for Cobalt Strike beacon traffic. The tool operates by authenticating incoming beacon communications against predefined Cobalt Strike Malleable C2 profiles to ensure traffic authenticity. The function acts as an intermediary layer between Cobalt Strike beacons and their command and control infrastructure, providing validation capabilities based on malleable C2 profile configurations. This allows operators to implement additional security measures and traffic filtering for their command and control communications. The tool leverages Azure's serverless computing platform to provide scalable relay functionality while maintaining the integrity of C2 communications through profile-based validation mechanisms.
