Guide to set up nginx as non-transparent SSL proxy, which subsitutes strings in the server responses

Use nginx as Non-Transparent SSL Proxy

Introduction

Many mobile apps have back-end API servers. They usually rely on the API replies to determine whether certain information is supposed to be shown. If the API responses could be manipulated on the fly, we may easily fool an unmodified app to expose some private data.

This manual guides you to set up nginx as non-transparent SSL proxy, which just subsitutes strings in the server responses (i.e. man-in-the-middle attack ourself). For both server-side (their API servers) and client-side (your device), the whole process is almost transparent.

# Instrument vmlinux STP, LDP and BLR instructions to protect RA and restrict jumpping
#
# Depends on:
# 1) a modified gcc that
# - outputs 2 nop's before stp x29, x30 instructions
# - outputs 1 nop after ldp x29, x30 instructions
# 2) a kernel built using gcc command-line options to prevent allocation of registers x16, x17, and x18
