SMS spoofing definition
SMS spoofing, also known as source address spoofing or text message spoofing, is a technique where a sender manipulates the source identifier on a text message to masquerade as someone else. This can make the message appear to come from a different sender (phone number or name) rather than the original source.

SMS spoofing examples
- Phishing attacks: Cybercriminals often use SMS spoofing to impersonate banks or other trusted entities, tricking recipients into revealing sensitive information.
- Caller ID spoofing: Similar to SMS spoofing, this tactic involves altering the caller ID to hide the caller's real identity.
Comparing SMS spoofing to similar techniques
SMS spoofing is somewhat like email spoofing, where the sender's email address is forged. However, while email spoofing is easily detectable through certain protocols (like SPF, DKIM), SMS spoofing is more difficult to detect because such protective measures are not yet widespread in the mobile communication sector.
