Nogotofail is a network security testing tool designed to help developers and security researchers spot and fix weak TLS/SSL connections and sensitive cleartext traffic on devices and applications in a flexible, scalable, powerful way. It includes testing for common SSL certificate verification issues, HTTPS and TLS/SSL library bugs, SSL and STARTTLS stripping issues, cleartext issues, and more.
Google is committed to increasing the use of TLS/SSL in all applications and services. But “HTTPS everywhere” is not enough; it also needs to be used correctly. Most platforms and devices have secure defaults, but some applications and libraries override the defaults for the worse, and in some instances we’ve seen platforms make mistakes as well. As applications get more complex, connect to more services, and use more third party libraries, it becomes easier to introduce these types of mistakes.
The Android Security Team has built a tool, called nogotofail, that provides an easy way to confirm that the devices or applications you are using are safe against known TLS/SSL vulnerabilities and misconfigurations. Nogotofail works for Android, iOS, Linux, Windows, Chrome OS, OSX, in fact any device you use to connect to the Internet. There’s an easy-to-use client to configure the settings and get notifications on Android and Linux, as well as the attack engine itself which can be deployed as a router, VPN server, or proxy.
We’ve been using this tool ourselves for some time and have worked with many developers to improve the security of their apps. But we want the use of TLS/SSL to advance as quickly as possible. Today, we’re releasing it as an open source project, so anyone can test their applications, contribute new features, provide support for more platforms, and help improve the security of the Internet.
