Remember CTurt? The dev who managed to run unsigned code via the 1.76 Webkit exploit on PS4 a few months ago? Remember his cool Pong port to the Webkit exploit? And the Cinoop port?
Well, @CTurt has done it again, and has managed to get his PS4 Kernel exploit working! Using the 1.76 webkit exploit, he's managed to dump the PS4's kernel, and plans on looking for more vulnerabilities that'll work with the latest firmware!
This is excellent news, and definitely a big first step when it comes to current gen hacking! Congratz to CTurt!
EDIT 12/18: CTurt has announced he'll be stopping PS4 development, however he has posted a detailed explanation of how to get the kernel exploit working on 1.76 on his github
It's safe to say this isn't the last we'll see of this exploit, and now that he's published some details on how to get it working, I imagine we'll see something neat here soon.
