Obfuscation, Stealth, and Non-Attribution in Automated Red Team Tools

In the rapidly evolving landscape of cybersecurity, large military and government organizations face ever increasing persistent and sophisticated threats against their enterprise networks. The challenge of defending these networks is compounded by the increasing complexity and stealth of cyber-attacks, which can evade traditional security systems and measures, and remain undetected for extended periods. As a result, the need for advanced defensive strategies and tools that can keep pace with these evolving threats has never been more critical, however, current automated red teaming tools are limited in their ability to emulate advanced persistent threat (APT) behaviors. Supporting such behaviors in automated security assessments and tools can be helpful for improving organizations’ cyber defense preparedness. This research demonstrates how obfuscation, stealth, and non-attribution techniques can be effectively automated into red teaming tools. We have enhanced our Cyber Automated Red Team Tool (CARTT) by integrating advanced evasion techniques to better simulate sophisticated cyber threats. By incorporating Metasploit Framework evasion modules and new custom Internet Control Message Protocol (ICMP) and Domain Name System (DNS) evasion capabilities into CARTT, its ability to evade detection by common security controls is significantly improved. In doing this, the research demonstrates how obfuscation, stealth, and non-attribution techniques can be effectively automated into red teaming tools. The enhanced CARTT has been tested in a virtualized operational environment, demonstrating its effectiveness in identifying vulnerabilities and assessing the robustness of security measures on a simulated enterprise network. The research results showed successful evasion of antivirus detection systems and covert data exfiltration using the newly implemented evasion techniques. The enhanced CARTT enables network managers as well as cybersecurity professionals to conduct more thorough evaluations of defense mechanisms against sophisticated threats, ultimately strengthening overall cybersecurity postures. The integration of sophisticated evasion techniques into CARTT represents a critical step in realizing the objectives of the DoD Cyber Strategy.
