This content is provided strictly for educational and informational purposes. It does not contain or endorse instructions for exploiting security vulnerabilities. What SS7 is: SS7 (Signalling System No.7) is the global signalling protocol used by telephone networks to set up/route calls, deliver SMS, handle roaming and lookup subscriber routing information. https://www.gsma.com/solutions-and-impact/technologies/security/t-isac-blog/ss7-securing-a-legacy-protocol-in-a-modern-threat-landscape-and-how-information-sharing-can-help-to-mitigate/ How SS7 attacks work: SS7 was built on mutual trust between carriers. If an attacker (or a compromised/rogue provider) can send messages onto the SS7 network, they can request a subscriber’s routing/location, re-route calls or SMS (including one-time codes), or manipulate message flows, enabling eavesdropping, SMS interception, or location tracking without touching the target’s phone. https://time.com/3641668/researchers-flaws-cellphone/ How likely / who can do this: Exploitation requires access to the signalling network or an intermediary who can send SS7 messages, this makes attacks practical for criminals who buy access, rogue operators, or well-resourced state actors, but not for a random internet script-kiddie. https://epic.org/documents/epic-v-cisa-ss7-cybersecurity-report/ What to do about it: Operators should deploy SS7/Diameter firewalls, strict peer vetting and anomaly detection, users should avoid SMS for critical 2-factor auth and prefer app-based or hardware MFA and end-to-end encrypted messaging for sensitive communications. https://www.gsma.com/solutions-and-impact/technologies/security/gsma_resources/fs-11-ss7-interconnect-security-monitoring-and-firewall-guidelines-v6-0/
