How to tell if a text message is spoofed?
SMS spoofing involves faking the source ID, by replacing it with alphanumeric text. This can be useful for mobile providers, but can lead to security issues such as social engineering. How can we as users, or the providers themselves, detect illegitimate SMS spoofing?
The answer to how to tell if a text message is spoofed is that the best way to detect if the message was spoofed or not is to check the message-centre. Normally, a spoofed source will have the message-centre show a different gateway from the network of the gateway where the originating source is.
Ex.
Spoofed ID: VERIZON Message-centre: +927566004455
Original ID: VERIZON Message-centre: +181800001111
