![]() ![]() For example, TLS can authenticate one or both. While those intuitively sound like the best solution, the standalone binaries come with a massively increased startup time (multiple seconds) because they first need to extract some stuff to temporary directories. In this case one could only try to obfuscate the protocol to make reverse engineering harder and to keep all important state and computation on the server side to protect against local modifications on the client side. Most cryptographic protocols include some form of endpoint authentication specifically to prevent MITM attacks. In short, we have four alternatives: Standalone Binaries. MITM attacks, consistency check techniques involving alternative. The client has full control over its site and can provide the proxy with the client certificate or could disable SSL pinning. An active man-in-the-middle (MITM) attack allows an attacker to become an intervening. Burp or others) then neither client certificate nor SSL pinning would help. If your goal is instead to prevent the client itself from reverse engineering or manipulating the application protocol by running some local MITM proxy (i.e. Of course, this makes it more complex since somehow the client must get and install the client certificate first. It can be used to intercept, inspect, modify and replay web traffic such as HTTP/1, HTTP/2, WebSockets, or any other SSL/TLS-protected protocols. If there is a risk that the client certificate gets retrieved one can back it by a smart card so that physical representation of the smart card in the client is needed and nobody can replicate the client certificate. Command Line mitmproxy is your swiss-army knife for debugging, testing, privacy measurements, and penetration testing. And is thus effective against MITM in corporate proxies where the proxy CA was added as trusted to each clients CA store but where the proxy usually does not retrieve client certificates installed on the client. You can use Prox圜hains in order to use the SOCKS5 proxy with any application, depending on the OS you are using. This certificate is impossible to simply replicate by a MITM. We have used some of these posts to build our list of alternatives and similar projects. Another alternative without subprocess, but probably not what you want: from mitmproxy.tools import main main. You can also require a client certificate issued by a CA you control. import os import sys from mitmproxy import http from mitmproxy.master import Master import mitmproxy.master as master from mitmproxy.addons import core from mitmproxy.proxy import Prox圜onfig. Additionally HSTS can be explicitly said which makes overriding certificate warnings impossible on modern browsers. So an attack against the client is not easily possible. Using another tool named mitmproxy, the traffic going to the host is. Other great apps like mitmproxy are Burp Suite, Charles, OWASP Zed Attack Proxy (ZAP) and HTTP Toolkit. ![]() ![]() The best alternative is Fiddler, which is free. MITM is only possible if the client side explicitly trusts the MITM (i.e. is not looking upon cryptocurrency as an alternative to the Canadian dollar. There are more than 10 alternatives to mitmproxy for a variety of platforms, including Mac, Windows, Linux, Online / Web-based and Android. It is unclear what exactly you want to prevent. ![]()
