SMS spoofing is a technique used to send text messages with a forged sender number or name, making the message appear as if it comes from a trusted source. Cybercriminals use SMS spoofing to deceive recipients into believing the message is legitimate, often to steal sensitive information, spread malware, or conduct phishing attacks. The recipient may see a familiar name or number, increasing the likelihood of responding or clicking malicious links. SMS spoofing can bypass basic security checks, making it a popular method in social engineering attacks. To protect against SMS spoofing, users should verify unexpected requests and avoid sharing personal information via text messages.
