Find out what it is, how it works and how to break out of it. Commands you may need to solve this level ssh, cat, more, vi, ls, id, pwd

http://overthewire.org/wargames/bandit/bandit25.html Bandit Level 24 → Level 25 Level Goal A daemon is listening on port 30002 and will give you the password for bandit25 if given the password for bandit24 and a secret numeric 4-digit pincode. There is no way to retrieve the pincode except by going through all of the 10000 combinations, called brute-forcing.

http://overthewire.org/wargames/bandit/bandit24.html Bandit Level 23 → Level 24 Level Goal A program is running automatically at regular intervals from  cron , the time-based job scheduler. Look in  /etc/cron.d/  for the configuration and see what command is being executed. NOTE:  This level requires you to create your own first shell-script. This is a very big step and you should be proud of yourself when you beat this level! NOTE 2:  Keep in mind that your shell script is removed once executed, so you may want to keep a copy around… Commands you may need to solve this level cron, crontab, crontab(5) (use “man 5 crontab” to access this)

http://overthewire.org/wargames/bandit/bandit23.html Bandit Level 22 → Level 23 Level Goal A program is running automatically at regular intervals from  cron , the time-based job scheduler. Look in  /etc/cron.d/  for the configuration and see what command is being executed. NOTE:  Looking at shell scripts written by other people is a very useful skill. The script for this level is intentionally made easy to read. If you are having problems understanding what it does, try executing it to see the debug information it prints. Commands you may need to solve this level cron, crontab, crontab(5) (use “man 5 crontab” to access this)

http://overthewire.org/wargames/bandit/bandit22.html Bandit Level 21 → Level 22 Level Goal A program is running automatically at regular intervals from  cron , the time-based job scheduler. Look in  /etc/cron.d/  for the configuration and see what command is being executed. Commands you may need to solve this level cron, crontab, crontab(5) (use “man 5 crontab” to access this)

http://overthewire.org/wargames/bandit/bandit21.html Bandit Level 20 → Level 21 Level Goal There is a setuid binary in the homedirectory that does the following: it makes a connection to localhost on the port you specify as a commandline argument. It then reads a line of text from the connection and compares it to the password in the previous level (bandit20). If the password is correct, it will transmit the password for the next level (bandit21). NOTE:   Changes to the infrastructure  made this level more difficult. You will need to figure out a way to launch multiple commands in the same Docker instance. NOTE 2:  Try connecting to your own network daemon to see if it works as you think Commands you may need to solve this level ssh, nc, cat, bash, screen, tmux

http://overthewire.org/wargames/bandit/bandit20.html Bandit Level 19 → Level 20 Level Goal To gain access to the next level, you should use the setuid binary in the homedirectory. Execute it without arguments to find out how to use it. The password for this level can be found in the usual place (/etc/bandit_pass), after you have used the setuid binary.

http://overthewire.org/wargames/bandit/bandit19.html Bandit Level 18 → Level 19 Level Goal The password for the next level is stored in a file  readme  in the homedirectory. Unfortunately, someone has modified  .bashrc  to log you out when you log in with SSH. Commands you may need to solve this level ssh, ls, cat

http://overthewire.org/wargames/bandit/bandit18.html Bandit Level 17 → Level 18 Level Goal There are 2 files in the homedirectory:  passwords.old and passwords.new . The password for the next level is in  passwords.new  and is the only line that has been changed between  passwords.old and passwords.new NOTE: if you have solved this level and see ‘Byebye!’ when trying to log into bandit18, this is related to the next level, bandit19 Commands you may need to solve this level cat, grep, ls, diff
