Caller ID Spoofing is a technique used to change the information displayed on a recipient's phone when receiving a call. This can make it appear as though the call is coming from a different number, often one that looks familiar or trustworthy. People may use this method for various reasons, including pranks or to hide their true identity. While some may use Caller ID Spoofing for harmless purposes, it can also be exploited for malicious activities, such as scams or harassment. Many countries have laws against this practice, as it can lead to fraud and compromise personal safety.
