Caller ID spoofing is a technique where a caller deliberately falsifies the information transmitted to your caller ID display to disguise their identity. This is often used by scammers or telemarketers to make their calls appear as if they are coming from a trusted source, such as a local business or government agency. The goal is to trick recipients into answering the call or divulging sensitive information. While caller ID spoofing can sometimes be used for legitimate reasons, it is frequently associated with fraudulent or malicious activities.
