Once a fraudster has a customer’s credentials and has attempted to login to their target’s account, SMS or outbound calling authentication should, in theory, stop them in their tracks. However, fraudsters have found a way to intercept these messages with SS7 being the gateway. Callsign's use of telecoms intelligence can help to prevent these risks.
