Hacker Mathieulh shared a string extracted from a PS4 kernel dump, from the latest 5.55 firmware. The string contains the date the firmware was compiled. This date, he says, is enough proof that he has a decrypted dump of the PS4’s 5.55 kernel.

Mathieulh had shared a similar string from firmware 5.53 a few days ago. This is proof that whatever exploit he and a few others have in their possession, hasn’t been patched by Sony’s recent updates. Firmware 5.55 was released less than a week ago, so this is pretty impressive.

His tweet even takes a jab at Sony by directly including their official twitter account in his message. He also uses the opportunity to taunt other hackers, stating he is he first to decrypt the 5.55 firmware.

When asked, he also replied there would not be an exploit release for 5.5x in a long time. The upcoming 5.05 kernel exploit is what we’ll have for now 🙂
