To keep things fair for everyone, the Cyber Discovery team doesn't provide hints or guidance on how to solve challenges, except where we do so in places like our blog for everyone to see. If you message into support or DM us in social asking for a hint... you'll receive only a "keep trying" reply from us.
If you're stuck try teaming up with some friends or other students in your class working on challenges: often 2 or 3 heads are better than one. If you're stuck on a challenge in CyberStart Game, make sure to read through the Field Manual: it's a great place to go to when you're stuck.
You're also expected to make use of all the tools at your disposal... and that includes Google! Unfamiliar with a word or technical term in a briefing? Do an internet search and see what you can learn, often just getting a little clarity on some unfamiliar language or new commands can get you unstuck.
