If you're reading this, you've probably already torn your hair out trying to intercept traffic from an app protected by Protectt.ai. You've seen the "SSL handshake failed" errors, watched your proxy log fill with incomprehensible gibberish, or — worst of all — watched the app open and then immediately close, detecting your every move.
After weeks of trial and error, countless reboots, and way too many late nights, I with my friend(Localhost) have developed a methodology that consistently works against this protection. This isn't a theoretical write-up — it's a battle-tested, step-by-step guide that assumes you have a rooted Android device with KernelSU and a healthy tolerance for technical deep-dives.
Before we begin, here's what I'm assuming you have:
· A rooted Android phone with KernelSU installed (not Magisk — we're using KernelSU for its superior kernel-level hiding capabilities)
· Working Basic and Device integrity (Strong integrity isn't necessary)
· Basic familiarity with ADB and shell commands
· Burp Suite installed on your computer
· Patience. Lots of it.
Now let's get to work.
Part 1: The Foundation — Root Detection Bypass
Protectt.ai's first line of defense is aggressive root detection. Before you can even think about intercepting traffic, you need to make your device look completely stock. This is the most critical layer — if root detection fires, nothing else matters.
1.1 Installing ReZygisk-Next and NoHello
The root hiding stack starts with ReZygisk, a modern reimplementation of the Zygisk API. Unlike Magisk's built-in Zygisk, ReZygisk is completely open-source and offers better compatibility with KernelSU. Think of it as the engine that powers everything else.
Installation Steps:
1. Download the latest ReZygisk-Next.zip from its official repository
2. Open KernelSU Manager → Modules → Install from storage
3. Select the ReZygisk-Next zip and flash it
4. Reboot your device
Next, install NoHello. This Zygisk module specifically focuses on hiding root and Zygisk presence from apps. The name is a bit ironic — it says "no hello" to root detection.
KernelSU & KernelSU Next users:
· Install ZygiskNext or ReZygisk
· Make sure the unmount setting is enabled for the target app in the Manager
· Disable Umount modules in settings for Manager (if exists)
The unmount setting is critical — it ensures that module files aren't visible to the target app's file system scans.
1.2 Vector: Your LSPosed Framework
Vector is what you need — it's a modern, actively maintained fork of LSPosed designed specifically for KernelSU. Unlike the original LSPosed, Vector provides a WebUI interface and works seamlessly with KernelSU's architecture.
Installing Vector:
· Download the Vector module from its GitHub releases
· Install via KernelSU Manager (same as any other module)
· Reboot your device
· Access the Vector manager through the notification panel or via WebUI
The Vector manager will appear in your notification shade after a successful reboot. From here, you'll control all your Xposed modules. Make sure you're using version 2.0 for the best KernelSU compatibility.
1.3 HideMyApplist: The Invisibility Cloak
Even if you hide root, Protectt.ai can detect the presence of root management apps themselves — KernelSU Manager, your terminal emulator, and even Vector itself. HideMyApplist (HMA) solves this by intercepting package manager queries and returning empty results for blacklisted apps.
Configuring HideMyApplist:
1. Install the HMA APK and activate it in Vector (Modules → enable toggle)
2. Open HideMyApplist and go to "Template manage"
3. Create a new template (name it "RootHide")
4. In the blacklist, select:
o KernelSU Manager
o ReZygisk (if it appears as an app)
o Your terminal app
o Any other root-related apps you have installed
5. Go to "Effective Apps"
6. Find your target Protectt.ai app and apply the "RootHide" template
The principle is simple: if the app can't see the tools, it can't detect them. This is the core of modern root hiding — it's not about removing root, it's about erasing evidence.
Part 2: Proxy and VPN Detection Bypass
Once root is hidden, you'll face the next obstacle: proxy and VPN detection. Many security-conscious apps check for active VPN connections, as VPN detection often indicates traffic interception.
2.1 Understanding VPN Detection
Apps detect VPNs primarily through the Android ConnectivityManager API, which can check NetworkCapabilities.hasTransport() to identify VPN interfaces. When a VPN is active, the system creates a tun0 interface — and apps can detect this.
2.2 The VPNHIDE Multi-Layer Solution
VPNHIDE is the most comprehensive solution I've found. It operates on multiple levels:
· Java Layer (Vector/LSPosed): Hooks Android's ConnectivityManager and related APIs
· Native Layer (kernel module): Hides VPN artifacts from:
o /proc/net/* file system probes
o ioctl() and getifaddrs() system calls
o Netlink interface queries
The beauty of VPNHIDE is that it leaves the target process completely untouched — no Xposed hooks, no inline hooks, no modified memory regions in the target process itself. This makes it extremely difficult to detect.
Setting up VPNHIDE:
1. Download the VPNHIDE-zygisk module zip for your device's version
2. Install via KernelSU Manager (same as any module)
3. Install the VPNHIDE APK
4. Open Vector/LSPosed manager → Modules → enable VPN Hide
5. Add "System Framework" to the module's scope (this is critical — no other apps should be in scope)
6. Reboot your device
7. Open the VPN Hide app to manage target apps. In protection tab select 'Tun' then select 'L' & 'Z' for target app and in Apps tab select 'O' for target app.
2.3 SuperProxy and VPN-Zygisk
VPNHIDE handles the detection, but you still need a clean way to route traffic through your intercepting proxy. This is where SuperProxy and VPN-Zygisk come in.
SuperProxy creates a local VPN service that tunnels all traffic through your chosen proxy server. What makes it special is that it works without requiring root access for the routing itself — the local VPN approach is harder for apps to distinguish from legitimate VPN usage.
VPN-Zygisk complements VPNHIDE by providing additional hiding for Zygisk modules that persist after app specialization, ensuring nothing leaks through the Zygisk layer.
For best results, configure SuperProxy with your Burp proxy details, then let VPNHIDE handle the detection bypass. The combination creates a clean, undetectable interception channel.
Part 3: The Certificate Problem
With root and VPN detection bypassed, you're ready to install your intercepting proxy's certificate. But there's a catch — the PortSwigger CA that Burp Suite uses is widely blacklisted. Many apps, including those protected by Protectt.ai, specifically look for the "PortSwigger" attribute in certificate subject names.
3.1 Why the Default Certificate Fails
Protectt.ai maintains a blacklist of common proxy CA certificates. If it sees "PortSwigger" anywhere in the certificate chain, it immediately terminates the connection or refuses to trust the certificate altogether.
3.2 Generating a Custom Certificate
The solution is to create your own CA certificate using OpenSSL, then import it into Burp Suite. This effectively "spoofs" the certificate with legitimate-looking attributes that won't trigger blacklists.
Step-by-Step Certificate Generation:
First, generate a self-signed CA certificate with OpenSSL:
bash
openssl req -x509 -newkey rsa:2048 -keyout ca-key.pem -out ca-cert.pem -days 730 -nodes
You'll be prompted for certificate details. Use realistic values:
· Country Name: US
· State/Province: California
· Locality: San Francisco
· Organization Name: (Your Company Name) — avoid "Test" or "PortSwigger"
· Common Name: (Your Domain) — use something believable
Next, convert the certificate to PKCS12 format for Burp Suite:
bash
openssl pkcs12 -export -in ca-cert.pem -inkey ca-key.pem -out burp-ca.p12
Importing into Burp Suite:
1. Open Burp Suite → Proxy → Options
2. Under Proxy Listeners, click "Import / export CA certificate"
3. Select "Import"
4. Choose "From PKCS12 keystore"
5. Select your burp-ca.p12 file and enter the password
6. Complete the import
3.3 Installing the Certificate with MoveCertificate
On Android 7 and above, user-installed certificates are not trusted for secure connections by default. You need to move your certificate to the system certificate store.
MoveCertificate automates this process and works perfectly with KernelSU:
1. Install the MoveCertificate module via KernelSU Manager
2. Enable OverlayFS in KernelSU settings if prompted
3. Install your custom CA certificate normally (Settings → Security → Install from storage)
4. Reboot your device
5. After reboot delete the certificate from user and check if your custom certificate is present in system
After reboot, the module automatically converts and moves the certificate to the system store, creating the necessary hash files. You can verify success by checking KernelSU's WebUI for the certificate module.
Part 4: SSL Pinning — The Final Boss
You've hidden root, bypassed VPN detection, and installed a clean certificate. Now you're ready to intercept traffic — but SSL pinning stands in your way.
4.1 How SSL Pinning Works
Certificate pinning (or SSL pinning) is a mechanism where the app hardcodes which certificates or public keys it trusts. Even if you have a trusted CA certificate installed, the app will reject your proxy's certificate because it's not the specific one the app expects.
4.2 TrustMeAlready: Your Pinning Bypass
TrustMeAlready is an Xposed module designed specifically to bypass SSL certificate validation and pinning. It hooks into the app's certificate validation logic and forces it to accept all certificates — including your proxy's.
Installing TrustMeAlready:
1. Download the TrustMeAlready APK from its GitHub releases
2. Install it as a normal APK
3. Open Vector/LSPosed manager → Modules
4. Enable TrustMeAlready
5. Critical step: Tap on TrustMeAlready in the modules list and scope it only to your target Protectt.ai app
6. Reboot your device
The scoping is important — running TrustMeAlready system-wide can interfere with other apps' security and may cause instability.
4.3 Why TrustMeAlready Works Where Others Fail
TrustMeAlready operates by hooking the certificate validation chain at multiple points, covering various SSL/TLS libraries and implementations. While newer alternatives like SSL Killer exist, TrustMeAlready remains highly effective against Protectt.ai when combined with the other layers we've built.
The Complete Workflow: Putting It All Together
Now that we've covered each component, let me walk you through the complete setup process from start to finish. Follow these steps in order:
Phase 1: Initial Setup
1. Root with KernelSU — Ensure KernelSU is properly installed and working
2. Install ReZygisk — Flash via KernelSU Manager → Reboot
3. Install NoHello — Flash via KernelSU Manager → Reboot
Phase 2: Framework Installation
4. Install Vector (LSPosed fork) — Flash module → Reboot → Verify notification appears
5. Install HideMyApplist — Install APK → Activate in Vector → Configure blacklist template
6. Add target app to HMA — Apply blacklist template to your Protectt.ai app
Phase 3: Proxy Bypass
7. Install VPNHIDE kernel module — Flash via KernelSU Manager
8. Install VPNHIDE APK → Activate in Vector → Add "System Framework" to scope
9. Configure SuperProxy — Set up with your Burp proxy details
10. Enable VPNHIDE for target app — Use the VPNHIDE app to manage blacklist
Phase 4: Certificate Setup
11. Generate custom CA certificate — Use OpenSSL (avoid PortSwigger identifiers)
12. Import into Burp — PKCS12 import method
13. Install certificate on device — Settings → Security → Install from storage
14. Install MoveCertificate — Flash via KernelSU → Reboot
15. Verify certificate is in system store — Check KernelSU WebUI or /system/etc/security/cacerts/
Phase 5: SSL Pinning Bypass
16. Install TrustMeAlready — APK installation → Activate in Vector
17. Scope TrustMeAlready — Enable only for your Protectt.ai target app
18. Final reboot — Full reboot to ensure all modules are loaded
Phase 6: Testing
19. Start your intercepting proxy — Burp Suite on your computer
20. Launch SuperProxy — Ensure VPN is active
21. Open your target app — Watch for successful traffic in your proxy logs
Troubleshooting: When Things Go Wrong
Even with all these layers, you may encounter issues. Here's what to check:
App crashes immediately on open:
· Verify HMA blacklist includes KernelSU Manager and Vector
· Check that ReZygisk unmount setting is enabled for the target app
· Try disabling TrustMeAlready temporarily to isolate the issue
SSL handshake failures:
· Verify your custom certificate doesn't contain "PortSwigger" identifiers
· Check MoveCertificate successfully moved the certificate to system store
· Ensure TrustMeAlready is properly scoped to the target app
"Network may be monitored" warning appears:
· This is expected but doesn't affect functionality
· MoveCertificate can suppress this warning
Traffic shows but is encrypted:
· Certificate isn't being trusted
· Try regenerating your custom CA certificate
· Verify MoveCertificate completed successfully
VPN detection persists:
· Ensure VPNHIDE is active and System Framework is in scope
· Check that no other VPN apps are interfering
· Try using only SuperProxy without additional VPN layers
Final Thoughts
Protectt.ai is a formidable protection — it's designed by security professionals who understand exactly how penetration testers think. But no protection is perfect. The layered approach we've built here exploits the fundamental reality of platform security: a system you physically control can always be modified to suit your needs.
The key is redundancy. Each layer we added addresses a specific detection vector, but they also provide coverage when one layer fails. VPNHIDE might bypass connectivity checks but leave file system traces — HideMyApplist covers that gap. TrustMeAlready handles pinning but doesn't touch root detection — that's what NoHello and ReZygisk are for.
Remember that security is a cat-and-mouse game. App developers will update their protections, and the community will find new bypasses. Stay current, keep your modules updated, and don't be afraid to experiment.
