Attestation Bypass & Banking Fix

Play Integrity Fix (PIF) Magisk Module

Created by chiteroman and maintained with osm0sis, Play Integrity Fix is the essential Zygisk module that bypasses Google Play Integrity API restrictions, restoring Google Wallet, contactless NFC payments, and banking apps on rooted Android devices.

Module Technical Profile

Developer / Maintainer: chiteroman & osm0sis
Module Type: Zygisk Native In-Process Hook & Property Injector
Requirements: Magisk v24.0+ (Zygisk enabled), Enforce DenyList configured
16KB Page Size Support: Fully supported on version 17.0+ (NDK r27 compiled)
Official GitHub: chiteroman/PlayIntegrityFix

How Play Integrity Fix Operates Internally

When an application (like Google Wallet or a banking app) queries Google Play Integrity, Google Play Services (GMS) requests a cryptographically signed hardware key attestation from the Android KeyStore. Because an unlocked bootloader reveals itself in the attestation certificate, PIF:

PIF Interception Mechanics

1. Zygote Ingress: Zygisk injects PIF directly into com.google.android.gms.unstable. 2. Keystore Hook: Intercepts Android KeyStore certificate generation calls. 3. Fallback Trigger: Simulates an older device profile where hardware attestation is unavailable. 4. Property Spoofing: Injects certified build properties (fingerprint, model, patch level) via resetprop. 5. Server Evaluation: Google servers evaluate basic software attestation -> Returns MEETS_DEVICE_INTEGRITY!

Step-by-Step Installation & Configuration Guide

Step 1: Configure Magisk Settings

Open the Magisk App -> tap the gear icon in the top right.
Enable Zygisk (or use standalone Zygisk Next).
Configure DenyList:
- Tap Configure DenyList -> tap the 3 dots -> check "Show system apps".
- Search for Google Play Services (com.google.android.gms) and check all processes (especially com.google.android.gms.unstable).
- Search for Google Play Store (com.android.vending) and check it.
- Search for your target banking apps and check all their processes.
Enforce DenyList Setting: If you are pairing PIF with Shamiko (recommended for banking stealth), keep Enforce DenyList TOGGLED OFF so Shamiko can hook in memory. If NOT using Shamiko, toggle Enforce DenyList ON.

Step 2: Flash the Module

Download the latest release zip from the official repository (GitHub Releases).
In Magisk App, go to Modules -> Install from storage -> select the downloaded zip.
Reboot your device.

Step 3: Clear GMS Cache & Test

ADB Cache Wipe Commands

$adb shell pm clear com.google.android.gms $adb shell pm clear com.android.vending $adb reboot

Handling Fingerprint Revocations (`custom.pif.json`)

When Google bans a public fingerprint, update the target device properties by placing a custom.pif.json file in /data/adb/pif.json:
