One common method used by scammers is often referred to as the “Yes” scam.
It typically follows this pattern:
- A caller asks a simple question
- The recipient answers “yes”
- The response is recorded
- The recording is later presented as proof of consent
That audio may then be used to falsely claim you agreed to a purchase, contract, or subscription.
Because of this, consumer-protection experts advise avoiding direct verbal confirmations when dealing with unknown callers.
Even “Hello” Can Be Exploited
Many automated or suspicious calls are not attempting to have a conversation.
Instead, they are checking:
- Whether a phone number is active
- Whether a real person answers
- Whether a voice sample can be recorded
Saying “hello” can confirm all three.
Even a short greeting can provide enough material to begin basic voice replication.
