Automating system-level device fingerprint countermeasures on Android, using Magisk, Zygisk, APatch, and ptrace to spoof fingerprints at scale, with the algorithm recovered in detail.
The Android property system from the inside: how properties work, how apps detect tampering through them, and how to hide fingerprints from a custom AOSP build.
How Android apps fingerprint your device and the countermeasures that defeat it, from ptrace and svc hooks to netlink and system-property spoofing, with every step broken down clearly.
Building a ptrace and seccomp sandbox for inline svc hooks, using BPF filters to intercept syscalls tracelessly and read their register arguments, so you can reproduce it yourself.
Getting a device's MAC address on Android without any permissions, using a netlink socket and inline svc calls to sidestep the OS's access controls, including the pitfalls and the fix.
