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 stealing the spare key from the cleaning company instead of breaking into headquarters.
Goal
Quietly stealing information
Like a spy who stays for months, copying files from the cabinet a little at a time.
