The detection rule focuses on identifying potential abuses of remote printing services that can lead to lateral movement within a network. It works by monitoring remote procedure calls (RPC) made through the Microsoft RPC Protocol, specifically the MS-RPRN and MS-PAR. These protocols enable remote printing capabilities and can be exploited by attackers for unauthorized access to other systems through lateral movement techniques. The rule captures specific Event Logs related to RPC Firewall activities, particularly any events that indicate manipulation attempts involving defined UUIDs associated with the printing service. By implementing this rule, organizations can detect and potentially prevent malicious use of remote printing capabilities that might indicate a compromise or an ongoing attack. The high severity level signifies the criticality of these actions in respect to network integrity and security.
