🌊 Leviathan Level 3 → Level 4

ssh leviathan3@leviathan.labs.overthewire.org -p 2223
leviathan3_password

After running the ls command, we found a program file named level3 and executed it.

ls -la
./level3

Then we executed ltrace to analyze how the program works and saw a string comparison function.

ltrace ./level3 

After that, we ran level3 again and obtained a shell.

./level3
snlprintf
whoami
cat /etc/leviathan_pass/leviathan4

Fantastic! This flag will allow you to progress to the next round.
