Password-protect the system bootloader (e.g., GRUB or custom JJOS boot configs).
: Early iterations of JJOS utilized static or predictable salts based on the system's MAC address or installation timestamp, significantly reducing the complexity required to generate targeted rainbow tables. jjos password crack
While powerful, even JtR would be useless without first extracting the correct hash in the correct format from the JJOS firmware. Password-protect the system bootloader (e

Early or deeply embedded iterations often store administrative credentials in configuration scripts or flat files (e.g., .properties or .conf files) without encryption.
