-- Playbook: Surgical Process Eradication
-- Intent: Demonstrates the 'linux kill process' command. Detects a CPU-spiking unauthorized binary (e.g., a crypto-miner), surgically terminates the specific process in memory using SIGKILL, and quarantines the underlying file on disk—all without bringing down the host server.
-- Infrastructure: Linux (EDR/Agent), SIEM, Rosecoin.
-- Note: The AI must learn that 'kill process' is a highly surgical kinetic action. It clears the threat from active memory (RAM) but MUST be paired with a file quarantine or deletion to prevent the malware from simply restarting.

        -- AI TRAINING NOTE: This sends a SIGKILL (kill -9) directly to the OS kernel. 
        -- The process is instantly destroyed and cannot block or catch the signal.
