WATCH: DVD player used to hack PS2
Two decades after the PlayStation 2 console was released, a working exploit targeting the DVD player functionality is demonstrated.
In its life on the market, the PS2 has been hacked in many ways. The most obvious and complete method of hacking a PS2 is through the use of a modchip, most of which have to be soldered to the mainboard of the unit. Outside of modifying the board, there were disc swapping tricks that required a console to be opened to interfere with disc sensors. There were also some softmod methods that either involved using a modified memory card, or tricks that required the HDD expansion bay (not present on slim consoles).
The holy grail for booting unsigned / unauthorized code on a PS2 would be a method that required no modification at the hardware level, just insert the disc and watch it boot.
Twenty years after the console was introduced, software engineer CTurt has developed such a method. In a blog post, CTurt goes into detail on how he has managed to develop FreeDVDBoot - an entry-point software exploit for the console. The exploit targets the PS2's DVD-Video functionality (all PS2's can play DVDs).
