Exposing The Flaw In Our Phone System

We demonstrated how SS7 vulnerabilities can be exploited to intercept phone calls, texts, and two-factor authentication codes—showing that even a normal-looking phone can be compromised remotely. 0:27

Key Takeaways:
• SS7, the backbone of 2G/3G networks, allows attackers to intercept calls and messages by exploiting weak authentication and roaming protocols 1:59.
• Attackers can reroute calls to a controlled number, making it appear as if the victim received the call when they didn’t 3:33.
• SMS two-factor authentication codes can be stolen in seconds during interception, enabling account takeover 18:26.
• Location tracking via SS7 is possible without GPS, pinpointing users to within a hundred meters in urban areas 21:45.
• Real-world cases, like the abduction of Princess Latifa, show SS7 attacks can be used to locate and target individuals 22:48.

SS7 remains a serious threat due to its widespread use and lack of global replacement, despite being vulnerable to abuse. Users should avoid SMS-based 2FA and use encrypted messaging apps like Signal or WhatsApp 30:14.
