CARBONATO Process Masquerading as kworker Kernel Thread on Linux

Detects the CARBONATO botnet using two distinct persistence and evasion techniques: masquerading user-space processes as kernel worker threads by setting command line arguments to '[kworker/u2:0]', or disguising mining binaries as the systemd-logind service. Legitimate kernel threads are spawned by PID 2 and lack an executable path, while the legitimate systemd-logind is expected to be spawned by systemd/init.
