Linux Privilege Escalation with SUID files

<h1>What is SUID bit set?</h1> Definition: SUID (Set owner User ID up on execution) is a special permission that allows other users run with the owner’s privileges. That’s why SUID files can be exploited to give adversaries the higher privilege in Linux/Unix system called privilege escalation. Mostly, root access is the goal of hackers when performing privilege escalation. SUID will be set by adding number 4 in the permission number when using chmod command. For example: 4777, 4600, 4500, 4000, etc. Note: Letter s or S in the permission both represent for the SUID file. They only switch to one another when the execute permission is set. To be more specific, let’s have a look at the following explanation. The following is the full permission of a file called demo_file (777). <a href="https://medium.com/go-cyber/linux-privilege-escalation-with-suid-files-6119d73bc620">Click Here</a>
