I surely hope you make your clues way more difficult than that. Or else the account will be owned in ten minutes once the competition opens.

I'm severely constrained for time at present (a beloved friend passed away last evening, fucking Covid, so I have to help and do work as well and more), but I'm very tempted to join in on such a hacking challenge.

Idea: Get a company (an anti-virus one, or a social site, etc.) or so to sponsor a prize. In exchange some of the questions can be about the sponsor, so it's great publicity for them.

Look at the real challenges hackers have to face to exploit a vulnerability, without getting technical, and include that in your clues.

Keep us updated, and make sure the competition happens. Or the bunny gets it. 😝
