Unmasking the attack : A Capture The Flag game.

This lab is a Capture The Flag (CTF) game. A flag is an element of information related to security, such as a password, an IP address…​ that has to be discovered in a "mission".

This CTF has 4 missions (in addition to the mission zero), so there are 4 flags for you to discover.

The mission briefing and first mission objective are described on the next page. Successive missions are described directly by the CTF Dashboard when they are unlocked.

Winning the CTF

To win, you must collect a maximum number of points. Each discovered flag brings you a certain amount of points:

  • Mission 1 : 100 points

  • Mission 2 : 150 points

  • Mission 3 : 80 points

  • Mission 4 : 240 points

The missions are in order. You need to complete one to unlock the next one. So you also have to be fast, real fast !

To help you go faster, each mission have some hints that you can have revealed. Each hint, however, will cost a small number of points.

Good luck !
