How an attack looks
A direct override: "ignore your instructions," mid-call.
Instructions hidden inside tool or web data: a CRM note, an order record or a webpage carrying text written for the agent, not the person reading it.
Staff impersonation: a caller claims to be an employee or the account holder to unlock actions meant only for a verified identity.
Refund or transaction pressure: a request outside policy, repeated or escalated, hoping persistence works where a direct ask would not.
