NoGoToFail: A Network Security Testing Tool For HTTPS And TLS/SSL Bugs

NoGoToFail: A Network Security Testing Tool For HTTPS and TLS/SSL Bugs. An on-path blackbox network traffic security testing tool.

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.

Design

Nogotofail is composed of an on-path network MiTM and optional clients for the devices being tested. See docs/design.md for the overview and design goals of nogotofail.

Dependencies

Nogotofail depends only on Python 2.7 and pyOpenSSL>=0.13. The MiTM is designed to work on Linux machines and the transparent traffic capture modes are Linux specific and require iptables as well.

Additionally the Linux client depends on psutil.

According to Google blog,
“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.”
