The Problem

SMS-based authentication and communication are vulnerable to SS7 exploits and SIM-based attacks that allow hackers to intercept verification codes, enabling account takeovers and malware delivery. Users lack visibility into whether their SMS messages are being rerouted and have limited options to protect themselves beyond switching to app-based authentication. The widespread reliance on SMS for 2FA creates critical security vulnerabilities that users can't easily detect or prevent.

Potential Solution

A mobile security app that monitors for SS7 interception attempts and alerts users in real-time when their SMS messages may be compromised. The service provides virtual phone numbers with secure VoIP routing to shield users' real numbers from exposure, integrates with popular services to replace SMS 2FA with more secure authentication methods, and offers a security dashboard showing SMS routing anomalies and potential threats.

Why Now?

SS7 vulnerabilities are increasingly exploited by cybercriminals, and high-profile attacks like Pegasus have raised public awareness of SMS security risks. Major platforms are slowly moving away from SMS 2FA, creating demand for transition tools that protect users during this vulnerable period.

Always Works, Always Simple I wish more systems were able to integrate into using Duo for MFA and personal verification. It’s always easy and never a hassle. Any security conscious company that uses Duo for their MFA is worth working with.
