Smishing is a form of social engineering that exploits SMS, or text, messages. Landline communication cannot be intercepted without physical access to the line however, this trait is not beneficial when communicating directly with a malicious actor. VoIP easily allows caller identity (ID) to be spoofed, which can take advantage of the public’s misplaced trust in the security of phone services, especially landline services. Advanced vishing attacks can take place completely over voice communications by exploiting Voice over Internet Protocol (VoIP) solutions and broadcasting services. This technique can be combined with other forms of social engineering that entice a victim to call a certain number and divulge sensitive information. Vishing is the social engineering approach that leverages voice communication.
