very almost PS4/PS5 Blu-Ray assaults: TheFloW shares his presentation slides will cowl the newest and most present instruction as regards the world. method in slowly fittingly you perceive capably and accurately. will layer your data cleverly and reliably

PlayStation hacker TheFloW has shared the slides (in pdf format, hyperlink under) for his presentation on the PS4/PS5 Blu-ray assaults. The slides add coloration and element to the report he revealed final week on HackerOne.

PS4/PS5 Blu-Ray Exploitation

The exploit chain revealed by TheFloW late final week is a brand new kind of exploit entry level, utilizing vulnerabilities within the Java layer, the BD-J interface, on each the PS4 and PS5 (most The PS3 is prone to be affected as effectively.)

Particulars in regards to the vulnerabilities can already be present in a report the safety researcher despatched to PlayStation through the HackerOne bounty program (hyperlink under), however these slides deliver a special approach to the reasons.

To start with, they present a part of the thought means of a hacker on the lookout for vulnerabilities in a console, and in that sense, the primary third of the slides are probably the most fascinating for me: what doable entry factors are there (Webkit, USB, DVD , Blu-ray file techniques…)? Which of them are value investigating (Webkit too harsh on PS5, some options eliminated, PS5 nonetheless a black field,…)? The hacker explains how BD-J is sensible on condition that the instruments are publicly accessible and also you needn’t perceive the inner construction of PS4/PS5 initially. He then proceeds to speak in regards to the doable assault vectors in BD-J (the JVM courses, JNI, and the Java courses themselves), and the best way to handle every of them.

After detailing this part of investigation, the slides describe the a number of vulnerabilities that TheFloW has discovered and chained collectively. These add coloration to the descriptions you already gave in your HackerOne report, and can little question turn out to be useful for different hackers attempting to duplicate your work.

Final however not least, Hacker explains how, mixed with a Kernel exploit, this will result in full management of the PS5. He would not share particulars in regards to the kernel exploit he is utilizing, although it is now fairly clear that that is how he ended up claiming victory on the PS5 late final yr, with a screenshot of the PS5’s debug settings.

In concept, the PS5 scene additionally has entry to a Kernel exploit (the PS4 Poobs4 exploit additionally affecting the PS5, to not point out the newest reveals), although no progress has been made publicly on that entrance.
