How they attack
Entry
Fake downloads via search ads
Like swapping a road sign so shoppers end up at a fake store that looks just like the real one.
Inside
Silencing the guards
Like unplugging the security cameras and alarms before getting to work.
Goal
Steal first, then lock
Like emptying the safe and then welding its door shut, demanding money twice.
