Mounting HDD in Linux

• Unlike the ps3, where every part of perconsole security (including the HDD) is dictated by the eid_root_key, the ps4 has two perconsole keys for the HDD, one is handled by SAMU (we cannot obtain this key atm) and the other is handled by the South Bridge / AEOLIA / BELIZE (which we can obtain)

• Here I describe the steps to mount your hdd on the pc using the cryptmount utility on Linux

Setup

• EAP HDD Key (check in your kernel dump and in hxxps://github.com/Ps3itaTeam/ps4-kexec/blob/master/magic.h kern_off_eap_hdd_key offset)
• Linux Distro (i'm using xubuntu live for this)
• cmtab file

Step by Step Guide

• cmtab file can be as follows (example for xubuntu live)

# /etc/cryptmount/cmtab - encrypted filesystem information for cryptmount
# try 'man 8 cryptmount' or 'man 5 cmtab' for more details
user {
    dev=/dev/sda27
    dir=/home/xubuntu/Desktop/user
    flags=user,nofsck

    fstype=ufs mountoptions=ro,noatime,noexec,ufstype=ufs2

    cipher=aes-xts-plain64
    keyfile=/home/xubuntu/Desktop/eap.bin
    keyformat=raw
}
