Exploit Farm

The utility for CTF hacker competition for launching sploits for all teams and submitting flags.

Prepare

  1. Set FLAG_FORMAT regexp in flag_format.py
  2. Set TEAMS in team_list.py
  3. Edit submit_flags in start_posting.py for the checking system

Usage

Starting a sploit

./start_sploit.py <sploit>

Launches sploit for all teams. Sploit should take team ip as first arg. Its output should contain flags. Flags will be saved in flags/<sploit_name>_<team_name>.txt

Starting the poster

./start_posting.py

Posts the flags in flags/*.txt to the checking system. Saves posted flags in posted_good_flags.txt and posted_bad_flags.txt.

Optimizing a sploit

If there are >100 teams, don't write a sploit like this:

hack(ip)

Write like this:

while True:
    hack(ip)
    sys.stdout.flush()
    sleep(30)

It is much faster.
