Why these techniques?

Improper access control on the on-chip debug interface enables physical attackers to connect via UART, gaining boot logs for system information discovery (T1082), a debug/root shell for Unix shell execution (T1059.004), and privilege escalation via exploitation of the interface (T1068).
