My favorite stereotypes are the race/STEM expert ones.
South Asia - programming, IT.
East Asia - Math
East Europe - Electrical Engineering
West Europe - High precision engineering and chemistry
At least as far as YouTube tutorials go, it’s basically cannon.
If you don’t have a specific goal, here are some ideas.
Build a NAS.
Use a bunch of small PCs or pis, build a CA, a DNS server. Make an db server and an app server.
Get shit running on your network.
Suit them all up with ELK stack.
Misbehave on your own network. Go find evidence for your misbehaving.
DoS yourself.
Without goals it’s tough to give ideas beyond general like this.
