Although I have tried most of the proxies that allow to modify web traffic “on the air” such as burp or WebScarab, I recently discovered a pretty interesting, not only because of its developers and the context in which it was presented, but also because of its features and architecture. Mallory Proxy is a proxy developed by the computer security experts Intrepidus that was presented at the Black Hat 2010.
Mallory is developed in Python and shows a server side and a client interface for configuration and user interaction.
For those who want to try Mallory, the application shows basically has two options. The first is to follow the installation instructions and download and install both proxy sources and dependencies. The second is to download a VMWare image whose operating system is Ubuntu and that comes with both software and dependencies.
