Neighbor spoofing is a type of spoofing in which scammers use automated calls to display a number that looks nearly identical to a user’s caller ID to get users to pick up the phone. The goal of neighbor spoofing is to fool users into thinking the call is coming from a “neighbor,” making them more inclined to answer.
The technique requires scammers to set the automated calling tools to display phone numbers with the same prefix as a user on caller ID. This tricks the user into thinking the call is from a neighbor instead of a scammer in another region.
