Samuel Groß exploits Safari at Pwn2Own 2018

The hacker behind this Safari sandbox exploit is Samuel Groß of the famed Pheonhex Dev Team. Just like the previous year, he again utilized the MacBook Touch Bar to exploit Safari.

He also executed unsigned code using a kernel vulnerability and changed the text of the Touch Bar.

The hacker bagged $65,000 along with the MacBook that he used to demonstrate the exploit.

Prior to Samuel Groß’s hacking attempt, famous hacker Richard Zhu aka Fluorescence also tried his hand at hacking Safari.

However, he was unable to hack Apple’s web browser in the allotted duration of 30 minutes.

After his first attempt failed, Zhu bounced back and successfully hacked the Microsoft Edge browser. He eventually ended up earning $70,000 despite failing twice in a row.
