The C:\\Windows\\Temp~nsu.tmp\\Au_.exe file is automatically launched as SYSTEM when the system reboots or when a standard user runs an MSI repair using Splashtop Streamer\u2019s Windows Installer. Since the C:\\Windows\\Temp~nsu.tmp folder inherits permissions from C:\\Windows\\Temp and Au_.exe is susceptible to DLL hijacking, standard users can write a malicious DLL to it and elevate their privileges."
