Tips:
-Turn off call forwarding to make an attacker’s access to your data impossible;
-Give up 2FA via SMS when the password is sent in the text, and use a two-factor identification software solution.
Many users choose to use mobile authentication because they are used to doing it, and the smartphone is always on hand. Positive Technologies, a company that specializes in cybersecurity, has demonstrated how easy it is to intercept an SMS with a password confirmation, transmitted practically worldwide by the Signaling System 7 (SS7) protocol.
Specialists were able to hijack the text messages using their own research tool, which exploits weaknesses in the cellular network to intercept text messages in transit. A demonstration was carried out using the example of Coinbase accounts, which shocked the users of the exchange. At a glance, this looks like a Coinbase vulnerability, but the real weakness is in the cellular system itself, Positive Technologies stated. This proved that any system can be accessed directly via SMS, even if 2FA is used.
