    Joseph Ravichandran, First year PhD Student working with Dr. Mengjia Yan at MIT. He/Him

    Presentation Title: The PACMAN Attack: Breaking PAC on the Apple M1 with Hardware Attacks
    Length of presentation: 45
    Demo, Tool, Exploit

    ABSTRACT

    What do you get when you cross pointer authentication with microarchitectural side channels?

    The PACMAN attack is a new attack technique that can bruteforce the pointer authentication code (PAC) for an arbitrary kernel pointer without causing any crashes using microarchitectural side channels. We demonstrate the PACMAN attack against the Apple M1 CPU.

    SPEAKER BIO

    Joseph Ravichandran is a PhD student in computer architecture studying microarchitectural security at MIT. His work includes microarchitectural and memory safety attacks and attack modeling. He plays CTF with SIGPwny. This is his first DEF CON talk.
