This rule correlates a sequence of suspicious activities on a single host within a 24-hour window, indicating a multi-stage intrusion typically associated with ransomware campaigns. The detection chain includes initial credential harvesting (using tools like Impacket, BloodHound, or potential agent drops), followed by defense dismantlement (deleting shadow copies, terminating security processes, and disabling the firewall), and ending with system auditing/recovery sabotage.
