How do hacker stray on microcontrollers exist?

Question

Burglary protection

For the sake of interest, I decided to assemble a HID for myself on attiny, everything worked out, but as it turned out, this was not enough for me. Is it possible to assemble something else, but more complex, on microcontrollers? Something to work with the network, sniffing or working with radio frequencies? I am a layman in this matter, but as for me it is very interesting.
