  1. Challenge

    Emulate

    Determine if the lab system is vulnerable to Dirty Pipe by running a script that checks the Linux kernel version and compares it against known vulnerable versions, then prove that the vulnerability is exploitable by running bleeding edge proof of concept code to gain root access to the system.

  2. Challenge

    Detect

    Create audit rules based on what you’ve learnt about the vulnerability and how it works, to alert on specific system calls.

  3. Challenge

    Protect

    Patch the kernel so that a non-vulnerable version of the splice system call is installed, but retain the original kernel so you carry out further testing.
