🎯 Content Summary

What this repository is
A GitHub repo titled “SSL Pinning Bypass for iOS — iptables” that provides bash scripts to build a repeatable traffic interception lab for iOS apps without jailbreaking, by forcing the device’s traffic through a researcher-controlled gateway and then transparently redirecting HTTP/HTTPS (80/443) to a local interception proxy (e.g., Burp Suite or mitmproxy) using OpenVPN + iptables NAT.

🔧 Technical Details

1. Transparent interception via VPN + iptables REDIRECT: Put a target device behind an OpenVPN tunnel so all traffic reaches a controlled Linux gateway on tun0, then add iptables NAT rules that redirect TCP flows destined to ports 80 and 443 to a local interception proxy port (e.g., 8080). This forces traffic into the proxy without configuring a client-side proxy per app/device, enabling scalable testing and capture of app traffic.
   
   2) “Invisible proxying” requirement for transparent mode: When redirecting traffic at L3/L4, the proxy must accept connections that were not explicitly configured to talk to it (i.e., transparent mode). Tools like Burp Suite support this via an “invisible proxying” option so the proxy can handle requests originally intended for arbitrary hosts/ports.
   
   3) Trust establishment for HTTPS decryption: To decrypt HTTPS in a MITM proxy, install the proxy’s CA on the device so t...

🤖 Agent Actions

Updated burp-configuration-for-ios.md with a new subsection covering transparent interception through an OpenVPN gateway plus iptables PREROUTING/POSTROUTING NAT, Burp invisible proxying, CA trust requirements, and the key limitation that this does not itself bypass real certificate pinning.

I kept the change in a single existing iOS Burp page, added the missing technical workflow and example rules, and appended a final ## References section with the GitHub repo and PortSwigger invisible proxy documentation. Verified the result with a file reread and git diff; no broader test/build step was run.
