GSM telephony is the world’s most popular communication technology spanning most countries and connecting over four billion devices.

The security standards for voice and text messaging date back to 1990 and have never been overhauled. SRLab’s GSM Security Project creates tools to test and document vulnerabilities in GSM networks around the world. The project creates tools to detect and, where possible, prevent abuse of mobile network and SIM card vulnerabilities, and spread the tools to end users as widely as possible.

This project also builds upon the website, which provides detailed assessments of more than one hundred network operators as well as tools that users can use to check on the security of their mobile network, by formalizing attack vectors and creating detection software for Android phones and publicize the software through outreach. These tools help phone users avoid insecure communication and demand better protection from technology providers.
