MeetC2 is a proof-of-concept (PoC) command-and-control (C2) tool developed to mimic cloud abuse using Google Calendar, aimed at helping cybersecurity teams test their detection, logging, and response capabilities. This innovative tool is part of a broader effort to understand and counter the methods used by modern cyber adversaries, who are increasingly embedding C2 traffic within legitimate cloud services to avoid detection.
The tool operates as a serverless C2 framework, utilizing Google Calendar APIs as a communication channel. This approach allows it to blend in with normal network traffic, making it a challenge for security systems that rely on traditional detection methods. By using a platform as widely used and trusted as Google Calendar, MeetC2 illustrates how adversaries exploit common cloud services to conduct malicious activities while evading security measures.
MeetC2 is designed primarily for educational and testing purposes, providing security professionals with a realistic simulation of how attackers might use legitimate cloud services for nefarious purposes. The tool supports cybersecurity teams in evaluating their current security infrastructures effectiveness in identifying and responding to such sophisticated threats. This can lead to improved defenses and more robust security protocols.
The emergence of tools like MeetC2 highlights the urgent need for continuous adaptation in cybersecurity strategies. As cloud services become more integral to business operations, understanding how they can be manipulated for cyber attacks is crucial. This tool not only aids in preparation and response but also serves as a reminder of the evolving tactics cybercriminals use to exploit technological advancements.
