It’s alive (once more)! Hacker TheFloW has taken to Twitter to announce how a slight modification of his BD-JB exploit permits to run the hack once more on PS5 Firmwares as much as 7.61 included. The vulnerability concerned on this modification has been allegedly patched in Firmware 8.00 by Sony.

BD-JB Exploit working on PS5s as much as Firmware 7.61

If you’re the proprietor of a PS5 with a BluRay disc, on firmware 7.61 and under, you’re most likely in luck, because it seems a minor modification of TheFloW’s BD-JB exploit permits the hack to run once more, as much as Firmware 7.61.

It was initially believed that BD-JB had been patched round PS5 Firmware 5.00, however the hacker had talked about this “revival” again in September this yr so this isn’t a “shock” in itself. But immediately TheFloW has printed the main points of the modification. This means Native PS5 code execution on Firmware as much as 7.61 ought to now be attainable.

However this isn’t a kernel exploit!

To be crystal clear, we’re speaking of usermode execution right here, and the PS5 Kernel exploit stays “reserved” to firmware 4.51 and under. Nonetheless, the BD-JB exploit may show to be resilient, and used once more as an entry level for future PS5 Jailbreaks, if a brand new Kernel exploit is ever disclosed. As a reminder, TheFloW has talked about he might need one thing in retailer for us on that entrance, however that has but to be disclosed.

Please notice that I’ve personally not examined this but.

The exploit must be burned onto a Blu-Ray disc. You can discover Blu Ray burners for moderately low cost on Amazon and different retailers (ensure that they assist BD-RE and Dual Layer DL). TheFloW has specified prior to now that he used Rewritable Verbatim discs (BD-RE) in his personal checks. (affiliate hyperlinks).
