Original Sony PlayStation 2 security chip 'broken wide open' after 26 years

The reverse engineering of Sony’s original PS2 security chip shows that even deeply embedded hardware protections can be decoded over time, creating new opportunities for preservation, emulation, and third-party repair. For CIOs and technology leaders, the strategic takeaway is that proprietary hardware controls should not be assumed to be permanent moats; IT organizations need lifecycle plans for aging devices, especially where operational continuity depends on vendor-specific chips, firmware, or authentication mechanisms.
