Print Processor DLL Registered for Persistence
This rule detects network traffic on TCP port 445 (SMB) containing the case-insensitive string "Print Processors". This pattern is indicative of an attempt to register a malicious Print Processor DLL for persistence, a technique used by adversaries to maintain access to a system. The rule specifically looks for traffic flowing to the home network, suggesting an inbound attempt to establish persistence.
