MiTM Instructions

This should work on anything, not just the e-Shop.

1. Get NoSSL IPS patch, either through dumping the SSL system module and patching it, or by retrieving a pre-made one.
2. Copy the previously-retrieved patch to /luma/sysmodules/0004013000002F02.ips on your 3ds' SD card
3. Set up some kind of proxy (e.g. mitmproxy) and use the following settings/variables:
   • client_certs: path to CTR cert (can be downloaded here)
   • tls_version_client_min: UNBOUNDED
   • ssl_insecure: true
4. Configure your 3DS to use mitmproxy's HTTP(S) proxy.
   • IP: private IPv4 address of proxy host.
   • Port: 8080
5. Start capturing! If you prefer a web interface instead, use mitmweb which is shipped with mitmproxy.
