The landscape of cybersecurity is in a constant state of flux, with defenders and attackers locked in a perpetual arms race. As detection mechanisms become more sophisticated, red teams and security researchers must adapt their tools and techniques to accurately simulate the tactics of real-world adversaries. While commercial command-and-control (C2) frameworks like Cobalt Strike and Sliver offer powerful capabilities, their signatures are often well-known to modern security solutions. This has led to a growing trend...
