OverTheWire: Bandit Level 15 to Level 16

Level goal: 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…

In this level, we connect to the port 30001 on localhost using the SSL encryption. We can do it using the openssl command.

bandit15@melinda:~$ openssl s_client -quiet -connect
depth=0 CN = li190-250.members.linode.com
verify error:num=18:self signed certificate
verify return:1
depth=0 CN = li190-250.members.linode.com
verify return:1


The password to gain access to the next level is cluFn7wTiGryunymYOu4RcffSxQluehd.
