Process Access via TrolleyExpress Exclusion for LSASS Dump
Detects a possible process memory dump of lsass.exe using a renamed or masqueraded executable named 'TrolleyExpress.exe'. This technique leverages the whitelisted nature of the legitimate Citrix TrolleyExpress.exe to evade detection while attempting to dump LSASS memory, often indicated by command-line arguments targeting process IDs in the 700-999 range or the '-ma' flag for memory dumping.
