Background for this topic.
SMS (Short Message Service) is a standardized mobile-network service for sending short text messages between phone numbers. It is widely used for person-to-person communication, service notifications, and one-time authentication codes, but messages are generally not end-to-end encrypted and may be visible to mobile operators or infrastructure handling delivery.
Security concerns include smishing—phishing delivered by text—along with sender-ID spoofing, malicious links, and social engineering. Account recovery and SMS-based multi-factor authentication can also be undermined when an attacker takes control of a phone number through SIM swapping, abuses carrier processes, or exploits signaling-system weaknesses. Organizations should avoid treating SMS as a high-assurance authentication factor where stronger options are practical, restrict sensitive content in texts, monitor number-change and authentication events, and train users to verify unexpected messages through a trusted channel.
