Method 1: Resetting Password using TIA Portal

• The S7-1500 uses an Infineon TriCore/ARM Cortex-R based SoC. Password hash is stored in the protected OTP (one-time programmable) region or encrypted external flash.
• By attaching to the Debug Access Port (DAP) over JTAG, an attacker can halt the CPU during boot (before security initialization) and dump the hashed password from a known memory offset (e.g., 0x8002_0000 for older FW).
• The hash is SHA-256 with a per-device salt (stored in the CPU’s unique ID). Cracking requires offline brute-force (hashcat mode 1400) – infeasible for strong passwords but works for weak/default ones.
