Description

This is a simple proxy server to inspect traffic as it goes to httpbin.org

If a request has a JSON payload, and in that payload there's a key value of {"is_malicious": true} then the proxy will intercept the payload and return a 403 error.

If a request repeats, the proxy will log a warning.

The proxy is built on Python and uses the Flask library

How to run

Prereqs

Install required libraries

pip install -r .\requirements.txt

Run the proxy

From the project root:

Curl Commands to get you going:

Simple curl:

curl --location --request GET 'http://0.0.0.0:8080/get'

Simple malicious test case

curl --location --request POST 'http://0.0.0.0:8080/post' \
--header 'Content-Type: application/json' \
--data-raw '{
    "is_malicious":true
}'

A slightly more complicated test case

curl --location --request POST 'http://0.0.0.0:8080/post' \
--header 'Content-Type: application/json' \
--data-raw '{
    "is_malicious":false,
    "hidden": {
        "some_value": {
            "is_malicious": false
        }
    }
}'
