I'm Kai from KSEC, UK/EU distributor for Hak5, SPARROWS, Pro Pick, Electronic Cats and other manufactures of cyber tools. My LinkedIn: https://www.linkedin.com/in/kai-c-724034b0/

A question I get a lot is where to start if you are more into hardware than code. This is the order I would suggest:

1. Locks first. Cheap, safe and it teaches you to think about how security fails mechanically. A clear practice lock and a basic pick set are enough.
2. RFID and access control. Learn how badges and readers talk to each other, then what a Proxmark can and cannot read.
3. USB and Wi-Fi tools. Keystroke injection and Wi-Fi auditing show you why physical access matters so much.
4. IoT and hardware. UART, SPI, sniffing and basic fault injection.

Good free resources for each: LockPickingLawyer and Lock Noob on YouTube for locks, the Iceman Proxmark3 wiki on GitHub for RFID.

We're also building free learning paths on onlysecurity.com that follow this order, with certificates: https://onlysecurity.com/learning-paths/ (free account needed).
