The Package That Ended PlayStation's Best Security
A blank Blu-ray disc, four dollars, with one word written on it in Sharpie. It revealed a flaw Sony never saw coming. This is the story of BD-JB, one of the most surprising discoveries in PlayStation 4 history, and how security researchers found it hiding inside the console's own disc drive. No modified hardware, no special tools, just an ordinary disc and a design decision that quietly changed everything. And with Sony now announcing the end of PlayStation game discs by 2028, the timing of this story raises a question the company would probably rather not answer.
