π Hello friends,
Today, we'll explore a method that most people tend to overlook β one that specifically targets Google's security mechanisms.
..................................................................
π§ Background Insight:
While analyzing Google's protection services, I noticed something interesting during the inspection of IPs and hosts that certain Android components regularly communicate with.
The method Iβll share is applicable within internal networks (LAN) which Iβll discuss briefly.
π§° What You Need:
- A Linux system (any distribution)
- A device connected to the same network
- A testing Android device
- A Man-in-the-Middle tool like Bettercap
- A basic understanding of how Bettercap works
..................................................................
π Target Hosts and IPs:
These are the key domains and IPs youβll be focusing on:
voledevice-pa.googleapis.com
142.250.187.142
connectivitycheck.gstatic.com
android-safebrowsing.google.com
play.googleapis.com
play-lh.googleusercontent.com
π§ͺ Based on my personal tests, this technique works on all Android versions up to Android 14.
..................................................................
π οΈ Implementation Using Bettercap:
Step 1: Host Discovery
Launch Bettercap and perform host discovery to find devices in your local network. You can narrow it down to your test device by targeting its IP address.
Step 2: Define Your Targets
Set your desired target device using:
set arp.spoof.targets <TARGET_IP>
Step 3: Enable DNS Spoofing
Here youβll block the communication with Google's security hosts.
set dns.spoof.targets voledevice-pa.googleapis.com,connectivitycheck.gstatic.com,...
set dns.spoof.all true
This will redirect all DNS queries (including those to Google protection services) to 0.0.0.0, effectively disabling them.
Step 4: Launch ARP Spoofing
Run:
arp.spoof on
dns.spoof on
This will route all the targetβs traffic through your machine.
..................................................................
π¦ What Happens Next?
After setting things up, you can install your payload or application on the target device. If successful, youβll notice:
- Google Play Protect wonβt flag the app during installation.
- No alerts or warnings will appear in the settings β everything looks clean.
..................................................................
β But What If Google Triggers Detection Later?
You might be thinking:
βBut bpass, what if Google analyzes the app after installation and flags it?β
Valid concern β but here are two countermeasures:
Auto-Reconnect Payload Logic:
Make the payload re-establish communication after being killed or interrupted.Blocking Google's App Behavior Analysis:
You can block Google's dynamic app analysis using advanced network filtering (details in the next article).
..................................................................
π§Ύ Conclusion
This technique shows that many Android devices rely on a specific set of hosts for protection routines. Blocking them at the network level (even temporarily) gives attackers a window of opportunity.
We'll cover the second stage β how to block behavior analysis and maintain persistence β in the next article.
