Bandit Level 0
This is a very simple level just connect the site to ssh like this ????????
ssh bandit.labs.overthewire.org -p 2220 -l bandit0
password: bandit0
Bandit Level 0-1
The password for this level is stored in the readme file and we are using the cat file.
ls
cat readme
To go to the next level enter ssh bandit1@localhost
Password: boJ9jbbUNNfktd78OOpsqOltutMc3MY1
Bandit Level 1-2
For this level the password is stored in ‘-‘ So, we are just entering cat ./-
ls
cat ./-
ssh bandit2@localhost
Password: CV1DtqXWVFXTvM2F0k09SHz0YwRINYA9
Bandit Level 2-3
For this level the password is stored in a file so, we are using the string ”
ls
cat ‘spaces in this filename’
ssh bandit3@localhost
Password: UmHadQclWmgdLOKQ3YNgjWxGoRMb5luK
Bandit Level 3-4
For this level, the password is stored in .hidden file and the file is hidden
ls
cd inhere/
ls
ls -1a
cat .hidden
ssh bandit4@localhost
Password: pIwrPrtPN36QITSp3EQaw936yaFoFgAB
Bandit Level 4-5
For this level, the password is stored only in a readable format.
ls
ls -1a

Bandit Level 5-6
For this level, the password is stored in ????????
- human-readable
- 1033 bytes in size
- not executable
ls
cd inhere/
ls
find . -size 1033c
cat ./maybehere07/.file2
ssh bandit6@localhost
Password: DXjZPULLxYr17uwoI01bNLQbtFemEgo7
Bandit Level 6-7
The password for the next level is stored somewhere on the server and has all of the following properties:
- owned by user bandit7
- owned by group bandit6
- 33 bytes in size
find / -user bandit7 -group bandit6 -size 33c
cat /var/lib/dpkg/info/bandit7.password
ssh bandit7@localhost
Password: HKBPTKQnIay4Fw76bEy8PVxKEDQRKTzs
Bandit Level 7-8
The password for the next level is stored in the file data.txt next to the word millionth
ls
cat data.txt | grep millionth
ssh bandit8@localhost
Password: cvX2JJa4CFALtqS87jk27qwqGhBM9plV
Bandit Level 8 – 9
The password for the next level is stored in the file data.txt and is the only line of text that occurs only once
cat data.txt | sort | uniq -u
ssh bandit9@localhost
Password: UsvVyFSfZZWbi6wgC7dAFyFuR6jQQUhR
Bandit Level 9 – 10
The password for the next level is stored in the file data.txt in one of the few human-readable strings, preceded by several ‘=’ characters.
ls
strings data.txt | grep =
ssh bandit10@localhost
Password: truKLdjsbJ5g7yyJ2X2R0o3a5HQJFuLk
Bandit Level 10 – 11
The password for the next level is stored in the file data.txt, which contains base64 encoded data

ssh bandit11@localhost
Password: IFukwKGsFW8MOq3IRFqrxE1hxTNEbUPR
Bandit Level 11 – 12
The password for the next level is stored in the file data.txt, where all lowercase (a-z) and uppercase (A-Z) letters have been rotated by 13 positions
ls
cat data.txt | tr a-zA-Z n-za-mN-ZA-M
ssh bandit12@localhost
Password: 5Te8Y4drgCRfCx8ugdwuEX8KFC6k2EUu
Bandit Level 12 – 13
The password for the next level is stored in the file data.txt, which is a hexdump of a file that has been repeatedly compressed. For this level it may be useful to create a directory under /tmp in which you can work using mkdir. For example: mkdir /tmp/myname123. Then copy the datafile using cp, and rename it using mv (read the manpages!)
ls
cat data.txt
mkdir /tmp/pavan
cp data.txt /tmp/pavan
cd /tmp/pavan
ls
file data.txt
xxd -r data.txt data1
file data1
mv data1 data2.gz
gzip -d data2.gz
file data2
mv data2 data3.bz2
bzip2 -d data3.bz2
file data3
mv data3 data4.gz
gzip -d data4.gz
file data4
tar -xvf data4
file data5.bin
tar -xvf data5.bin
file data6.bin
mv data6.bin data7.bz2
bzip2 -d data7.bz2
file data7
tar -xvf data7
file data8.bin
mv data8.bin data9.gz
gzip -d data9.gz
file data9
cat data9
ssh bandit13@localhost
Password: 8ZjyCRiBWFYkneahHwxCv3wb2a1ORpYL
Bandit Level 13 – 14
The password for the next level is stored in /etc/bandit_pass/bandit14 and can only be read by user bandit14. For this level, you don’t get the next password, but you get a private SSH key that can be used to log into the next level. Note: localhost is a hostname that refers to the machine you are working on
ls
ssh bandit14@localhost -i sshkey.private
Password: NO
Bandit Level 14 – 15
The password for the next level can be retrieved by submitting the password of the current level to port 30000 on localhost.
cat /etc/bandit_pass/bandit14
telnet localhost 30000
Paste the password in the escape characters, then you get the correct password
ssh bandit15@localhost
Password: BfMYroe26WYalil77FoDi9qh59eK5xNr
Bandit Level 15 – 16
The password for the next level can be retrieved by submitting the password of the current level to port 30001 on localhost using SSL encryption.
Helpful note: Getting “HEARTBEATING” and “Read R BLOCK”? Use -ign_eof and read the “CONNECTED COMMANDS” section in the manpage. Next to ‘R’ and ‘Q’, the ‘B’ command also works in this version of that command…
openssl s_client -connect localhost:30001 -ign_eof
Now, paste the previous level password
BfMYroe26WYalil77FoDi9qh59eK5xNr
Now, You will get the correct password
ssh bandit16@localhost
Password: cluFn7wTiGryunymYOu4RcffSxQluehd
Bandit Level 16 – 17
The credentials for the next level can be retrieved by submitting the password of the current level to a port on localhost in the range 31000 to 32000. First find out which of these ports have a server listening on them. Then find out which of those speak SSL and which don’t. There is only 1 server that will give the next credentials, the others will simply send back to you whatever you send to it.
nmap -A localhost -p 31000-32000
openssl s_client -connect localhost:31790
Now, enter the previous level password
cluFn7wTiGryunymYOu4RcffSxQluehd
Copy the RSA Private key
mkdir /tmp/techyrick_ssh
cd /tmp/techyrick_ssh
nano techyrick.private
Paste the RSA private key in nano techyrick.private, It will ask press enter once you enter you should paste the key.
Once paste ctrl +x and y
chmod 600 pavan.private
ssh bandit17@localhost -i pavan.private
Password: Not required
Bandit Level 17 – 18
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
ls
diff passwords.old passwords.new
ssh bandit18@localhost
Password: kfBf3eYk5BPBRzwjqutbbfE887SVc5Yd
Once you enter the password you will see connection to the localhost host closed which means we have cleared this round.
Bandit Level 18 – 19
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.
ssh -T bandit18@localhost
Once you enter this you will see a blank terminal and ther you enter
ls
cat readme
ctrl + c
ssh bandit19@localhost
Password: IueksS7Ubh8G3DCwVzrTd8rAVOwq3M5x
Bandit Level 19 – 20
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.
ls
./bandit20-do
./bandit20-do cat /etc/bandit_pass/bandit20
ssh bandit20@localhost
Password: GbKksEFF4yrVs6il55v6gwY5aVje5f0j
Bandit Level 20 – 21
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: Try connecting to your own network daemon to see if it works as you think
*For this level open two terminals and login to bandit level 20
On the left terminal enter ls
ls
./suconnect
Now on the right terminal enter
nc -lvp 4444
Now, on the left terminal enter
./suconnect 4444
Now, on the right terminal enter the previous level password, As soons as you enter you get the password on the left terminal.
ssh bandit21@localhost
Password: gE269g2h3mw3pwgrj0Ha9Uoqen1c9DGr
Bandit Level 21 – 22

ssh bandit24@localhost
Password: UoMYTrfrBFHyQXmg6gzctqAwOmw1IohZ
Bandit Level 24 – 25
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.
nc localhost 30002
mkdir /tmp/pavan2
cd /tmp/pavan2
nano bruteforcer.sh
Inside the nano edito enter
#!/bin/bash
passwd=”UoMYTrfrBFHyQXmg6gzctqAwOmw1IohZ”
for i in {8000..8999}
do echo $passwd’ ‘$i >> output.txt
done
chmod 777 bruteforcer.sh
./bruteforcer.sh
cat output.txt | nc localhost 30002 >> result.txt
sort result.txt | uniq -u
ssh bandit25@localhost
Password: uNG9O58gUE7snukf3bvZ0rxhtnjzSGzG
Bandit Level 25 – 26
Logging in to bandit26 from bandit25 should be fairly easy… The shell for user bandit26 is not /bin/bash, but something else. Find out what it is, how it works and how to break out of it.
ls
ssh bandit26@localhost -i bandit26.sshkey
cat /etc/passwd | grep bandit26
cat /usr/bin/showtext
:set shell=/bin/bash
