South Korean hacker Gezine (screen name) dropped a blockbuster in the gaming industry: After a year and a half of careful research, he successfully broke through the PS5 defense system by using a vulnerability that even Sony was not aware of. However, what awaited him was not cheers of victory and widespread recognition, but a flood of criticism because he refused to disclose the details of the cracking tools or methods.

According to Gezine himself, the key to success lies in a bug in the Blu-ray disc processing mechanism. The code BD-JB4-1350 is clearly visible on the screenshots it published, which directly points to the optical disc drive as a breach of intrusion. In Sony's worst nightmare, the hacker exploited the console's unchangeable BootROM key. This means that this is a "hardware-level" vulnerability: it exists in every version of PS5 produced to date, and cannot be patched through a software update.

Gezine emphasized that information about the BootROM key did not appear in the public domain until around 2026, which helped him deduce this "blind spot" in the defense system. Despite this, he claims he has no plans to release ready-made jailbreak tools online.

The claim sparked outrage in the enthusiast community. Many users publicly insulted Gezine, accusing him of purely seeking attention and popularity, and demanding that he share his findings. However, experts caution that the PS5 has only been on the market for less than six years, and this incident is an extremely rare case of cracking a current-generation console. For comparison, the 13-year-old Xbox One was only recently completely compromised. For now, the vulnerability remains a secret that only exists in the hands of one person, and Sony still has a little time to prepare for a possible cracking frenzy in the future. Of course, that's assuming Gezine's method isn't rediscovered by others.
