LOLBAS ftp.exe -s Flag Executes Hidden Script from Mounted VHD

Detects the execution of the Windows ftp.exe binary using the -s parameter (or -s"": syntax) to execute a script file. This behavior is commonly associated with attackers using LOLBAS (Living Off the Land Binaries and Scripts) techniques to execute hidden or obfuscated scripts from mounted virtual hard disks (VHD) to facilitate malicious backdoor execution.
