How they attack
Entry
Fake job offers and interviews
Like a recruiter with a dream job who asks you to open a 'test assignment' that is actually booby-trapped.
Entry
Getting in through a supplier
Like stealing the spare key from the cleaning company instead of breaking into headquarters.
Goal
Stealing cryptocurrency
Like taking over the vault keeper's computer and opening the vault while pretending to be them.
