Jyrki Muukkonen emailed me to say that he defeated the laughably easy hacking challenge. The challenge was to decode the string:
If you look closely you will notice the numbers are from 0 to 7 indicating that this could be octal - which it is. With a little bit of conversion you get the message:
You must be a hacker.
I’ll leave out the details for those who’d still like to decifer it on their own. Look for a new hacking challenge soon.
