Need some input from all you #infosec tooters this morning:

I put on a training for our junior analysts every month covering something they've requested, or something outside of the normal comfort zone to expand their view of security. They currently do analysis of customer logs (Network, Host, EDR), basic SOC as a service type stuff.

Two months ago this was setting up Wireshark and breaking down the basics of packet analysis.

Last month this was walking them through how to use #SecurityOnion to work through one of the exercises from my buddy @malware_traffic .

So, I am looking for some suggestions on a training for this month that can run roughly 40 minutes that might be something these youngins haven't experienced that might spark their interest.

Bonus points if this can be performed in a lab environment to let them eventually build it out themselves and run with it.
