Nápověda:

A hacker named John made the backdoor for the first problem. He got really
angry when he realized that other HackersLab members were taking his backdoor
for granted. He had worked on it very hard for one day and now he thinks that
he can feel rest assured thinking that no one else can use the backdoor. Drive
him mad again!


Řešení:
Hledaný soubor je "/lib/security/pam_auth.so".

[level5@drill level5]$ cd /lib/security
[level5@drill /lib/security]$ ./pam_auth.so
passwd:
passwd incorrect!

No, tak teď musíme zjistit heslo:

[level5@drill /lib/security]$ less pam_auth.so

Někde tam najdeme přibližně toto:

^@^@^@^@^@^@^@^@^@^@^@^@what the hell are you thinking?^@abcd1234 ^@1qaz2wsx^@0pl mfk3s^@qkqh^@fj3,n34k $^^@fgjk3!mfr*^@Best of The Best Hackerslab ^@tkfkdgo!^@love you!^@D873nmf9^@apple123~^@flr1234^@passwd:^@sh^@/bin/sh^@passwd incorrect ^@^@^@^@^@^@^@^@^@^D<97>^^@^@^@ ^@^@^@^@^@^@^@^@^@^@^@^@^@
<<97>^^@^@^@^@^@^@^@^@<83>^<83>^<83>^<83>^<83>^


Takže teď zkusíme hesla "Best of The Best Hackerslab",
nebo "love you!":

[level5@drill /lib/security]$ ./pam_auth.so
passwd:
[level5@drill /lib/security]$ /bin/pass

A heslo je na světě!
