In early May 2025, Unit 42 researchers observed that AdaptixC2 was used to infect several systems. AdaptixC2 is a recently identified, open-source post-exploitation and adversarial emulation framework made for penetration testers that threat actors are using in campaigns.
Unlike many well-known C2 frameworks, AdaptixC2 has remained largely under the radar. There is limited public documentation available demonstrating its use in real-world attacks. Our research looks at what AdaptixC2 can do, helping security teams to defend against it. AdaptixC2 is a versatile post-exploitation framework. Threat actors use it to execute commands, transfer files and perform data exfiltration on compromised systems. Because it’s open-source, threat actors can easily customize and adapt it for their specific objectives. This makes it a highly flexible and dangerous tool.
