Hacker CTurt has announced earlier today that he will be leaving the hacking Scene. The hacker has contributed to some major breakthroughs in PS4 and PS5 hacking through his involvement in the scene since 2015, including the recently released Mast1c0re exploit, as well as the very first public Jailbreak for the PS4, on firmware 1.76 back in 2016.

CTurt’s contributions to the PlayStation hacking scene

There are many hackers involved in the PS4/PS5 hacking scene, but only a handful have had an impact similar to that of CTurt.

Back in 2016, the hacker published details of the very first Jailbreak for the PS4, on firmware 1.76 at the time. The dlclose exploit remained the only public way to hack your PS4 for a very long time, until the 4.05 Jailbreak (disclosed by Fail0verflow and implemented by SpecterDev).

It’s worth noting that at the time, the hacker had already announced he would stop working on PlayStation hacking, and that turned out to not be entirely true.

Much more recently, CTurt released a hack for the PS2 (yes, you read that correctly) which has the particularity of being compatible with slim versions of the console.

In recent years, CTurt has been particularly active on the PS4/PS5 scene, working directly through the HackerOne bug bounty to report his findings to Sony. He’s been awarded multiple high level bounties for his exploits, some of which we have to assume will never be publicly released. One of them however was the Mast1c0re exploit, a PS2 vulnerability on PS4 and PS5, which to this day is the only way to run unsinged code on the PS5’s latest firmware.

CTurt is leaving the hacking scene

Although he is not giving any specific reason, CTurt has taken to Twitter today to state he is leaving the scene. As I’ve mentioned above, he had already technically “stopped” working on PS4 hacks back in 2015, so maybe this is just temporary, but who knows.

This possibly means we will never see “part 2” of the Mast1c0re exploit writeup. The hacker has stated he is considering publishing it, but it is unfinished.

So long CTurt, and thanks for all the fish!
