This service offers challenges to improve your hacking skills.
Capture the flag to resolve the challenge. The default format for all flags is CanHackMe{...}.
And authenticate the flag you captured. If you've done it, you get points for the challenge.
You can see the ranking on the scoreboard and compete with other users.
If you don't give up, you can hack me. Have fun challenges!
