Network Traffic Interception Tool Developed Open-Source Under Name InterceptSuite

Sourav Kalal, a developer based in the UK, has unveiled InterceptSuite, an open-source, cross-platform network traffic interception tool. Designed for TLS/SSL inspection, analysis, and manipulation, InterceptSuite offers a unique solution for analysing network traffic beyond just HTTP.

InterceptSuite is built using C and leverages native SOCKS5 proxy support on Linux, Mac, and Windows, with OpenSSL for TLS. The tool currently supports non-HTTP protocols, HTTP/1, and HTTP/2, as well as specific IoT protocols like MQTT. It also offers support for databases, SMTP, and custom protocols, and can manage unknown protocols and their TLS connections.

One of the standout features of InterceptSuite is its ability to intercept plaintext protocols that transition to TLS, thanks to its support for TLS upgrades like STARTTLS and custom upgrades. This makes it an invaluable tool for network security analysis and research.

In a recent announcement, Kalal revealed plans to release VPN server support for InterceptSuite in the coming months. This addition will extend InterceptSuite's interception capabilities to proxy-unaware applications, enabling traffic to be redirected to InterceptSuite, thus supporting both TCP and UDP. The VPN server support will also allow InterceptSuite to intercept traffic from Android and iOS devices.

InterceptSuite features a cross-platform C# GUI and supports Python extensions for protocol dissection. This versatility makes it accessible to a wide range of users, regardless of their programming expertise.

InterceptSuite is available for free on GitHub, making it an affordable option for individuals, organisations, and researchers seeking a powerful network traffic analysis tool. While some features, like STARTTLS and PCAP support, are not included in the open-source version, the core functionality remains robust and valuable.

In summary, InterceptSuite is a versatile and powerful open-source tool that offers a comprehensive solution for network traffic interception, analysis, and manipulation. Its upcoming VPN server support promises to further expand its capabilities, making it an even more indispensable tool for network security professionals and researchers alike.
