Why these techniques?

Unauthenticated directory traversal enables arbitrary file read (e.g., /etc/passwd), facilitating public-facing app exploitation (T1190), local system data collection (T1005), local account discovery (T1087.001), /etc/passwd credential dumping (T1003.008), and credentials in files (T1552.001).
