MeetC2

MeetC2 is a proof-of-concept C2 framework using Google Calendar API as a covert communication channel between operators and a compromised system.

Introduction

MeetC2 is a cross-platform C2 framework that abuses Google Calendar APIs for covert communication. It allows red and blue teams to emulate and study command-and-control techniques that hide within legitimate cloud services.

Key Features:

  • Covert Communication: Uses Google Calendar API to create a hidden communication channel.
  • Cross-Platform: Compatible with macOS and Linux.
  • Emulation of Cloud Abuse: Demonstrates how legitimate cloud services can be abused for adversarial operations.
  • Reproducible Validation: Provides a way to validate detections, logging, and third-party app governance for cloud-abuse C2.

Use Cases:

  • Red Team Exercises: Simulate real-world C2 scenarios using a trusted SaaS domain.
  • Blue Team Training: Train defenders to detect and respond to cloud-based C2 traffic.
  • Security Research: Study the effectiveness of cloud-based C2 techniques.
  • Purple Team Exercises: Validate detections, logging, and governance controls.
