Inside The Gentlemen: Undisclosed TukTuk C2 Framework and EDR Neutralization Research
Analysis of server infrastructure revealed a complete TukTuk C2 framework (version 2.0) with cross-platform capabilities, including Windows and Linux agents, backend infrastructure, and management panel. The server contained eb.sys matching GentleKiller, along with comprehensive EDR neutralization training materials organized in four progressive lessons covering BYOVD techniques, vulnerable driver hunting, and kernel-level research. DLL sideloading configurations targeting Greenshot, ProcMon, Slack, and Postman were identified. Exfiltrated data included 224 Jira tickets from a global technology company containing information related to U.S. defense organizations and defense contractors, plus credentials from a global healthcare company's Infrastructure-as-Code platform exposing AWS keys, production databases, Azure AD, and Bitbucket access.
