How they attack
Entry
Exploiting internet-facing devices
Like finding a broken lock on the company's front gate (VPN or firewall) and walking in.

Like tampering with the telephone exchange so that certain calls are quietly copied to another line.
Goal
Quietly stealing information
Like a spy who stays for months, copying files from the cabinet a little at a time.
