Suspicious ASEP Registry Modification
This rule detects the creation or modification of registry values within common Auto-Start Extensibility Point (ASEP) Run keys. It specifically flags entries that point to suspicious file paths (e.g., C:\Users\Public\, C:\ProgramData\, temporary directories) or contain suspicious command-line interpreters (e.g., rundll32, mshta.exe, powershell.exe, wscript.exe, cscript.exe). The rule filters out modifications made by known legitimate processes to reduce false positives.
