Potential Persistence Via Event Viewer Events.asp Registry Modification
This rule detects attempts to establish persistence by modifying specific registry keys related to the Windows Event Viewer's redirection functionality. Adversaries can manipulate these keys, specifically 'MicrosoftRedirectionProgram' and 'MicrosoftRedirectionURL', to execute arbitrary programs or open malicious URLs when a user interacts with the Event Viewer. The rule filters out legitimate modifications made by svchost.exe (likely via GPO) for default redirection programs and command-line parameters, as well as the default Microsoft events.asp URL and empty values, to reduce false positives.
