Kov-Sec is a professional Android application protection platform. It converts your app's bytecode into an internal virtual machine (VM) and applies multiple layers of hardening that make it extremely difficult to reverse engineer, tamper with, or hack.
Your app remains 100% functional on Google Play Store — fully compatible with Play Store requirements, App Bundles (AAB) and APK distribution.
| Requirement | Support |
|---|---|
| APK & AAB formats | Supported |
| Signing (V1/V2/V3) | Supported |
| Android 7.0+ (API 21+) | Supported |
| arm64-v8a, armeabi-v7a, x86, x86_64 | Supported |
| Minimal size increase | Yes |
What it protects: Detects and blocks hooking frameworks that try to modify your app's behavior.
Against: Frida / Frida Gadget, Xposed / LSPosed / EdXposed, Zygisk, Substrate / Cydia.
What it does: Scans the running process for any sign of hooking frameworks. If something suspicious is detected, it immediately stops the app.
What it protects: Prevents dynamic debugging of the app.
Against: gdb / lldb / Android Studio debugger, debuggers that attach to the process to bypass checks or steal data.
What it does: Checks whether a debugger is attached to the process. If one is detected, it immediately stops the app.
What it protects: Detects that the app is NOT running on an emulator.
Against: BlueStacks, Nox, LDPlayer, MEmu, Genymotion — Android emulators used to automate, clone or exploit the app.
What it does: Detects characteristics that only emulators have, including fake hardware and sensors. If an emulator is detected, it immediately stops the app.
What it protects: Detects devices with root (superuser) permissions.
Against: Magisk, KernelSU, APatch, SuSFS, Shamiko — any rooted device that allows injecting, modifying or reading the app with full privileges.
What it does: Detects rooted devices using multiple advanced techniques, including modified kernels and hidden root frameworks. If root is detected, it immediately stops the app.
What it protects: The virtual machine (VM) that interprets your protected code.
Against: Code modification, VM modification, hooks that redirect VM functions.
What it does: Converts the app code into bytecode executed by an internal VM (layered protection). Verifies the code integrity. If someone tries to modify the VM, it stops the app.
What it protects: Verifies the APK signature against repackaging.
Against: Someone downloads your APK, modifies it and re-signs it with their own key (repackaging). Malware pretending to be your app.
What it does: Calculates the hash of the V1+V2/V3 APK signature and compares it against the expected signature. If it doesn't match, it stops the app.
What it protects: Detects DEX files that don't come from the original APK.
Against: Dex code injection at runtime, frameworks that load malicious classes on the fly, game modifiers that inject code.
What it does: Lists the ClassLoaders and DexFiles loaded. Compares against the legitimate dex of the APK. If an extra DEX is loaded, it kills the app.
What it protects: Blocks ADB shell access on the device.
Against: Someone connects the phone to a PC and uses ADB to view internal logs, extract app files, inject commands or get shell access to the process.
What it does: Detects if ADB is enabled. Detects USB debugging connections. If ADB is active, it kills the app.
What it protects: Detects libraries injected into the process.
Against: Libraries injected into the process by hackers, hooking libraries, and malware that injects into legitimate apps.
What it does: Verifies that all loaded libraries come from the app itself. If a strange library is found, it stops the app.
What it protects: Removes all Log.* calls from the DEX files.
Against: Information leaked by logs that hackers use to understand your logic, malware that reads logs from other apps, easier debugging for the attacker.
What it does: Goes through all DEX files and removes Log.v, Log.d, Log.i, Log.w, Log.e calls. Reduces the app size. Removes useful information for the attacker.
What it protects: Prevents screen recording and sharing.
Against: Screen recording (OBS, AZ Recorder), screen sharing (Discord, TeamViewer), screen casting to TV/PC, screenshots of sensitive content.
What it does: Detects if the app content is being captured (MediaProjection, presentation, virtual display). Hides or blocks content if capture is detected. Detects screenshots during sensitive actions.
What it protects: Blocks software keyloggers and input capture.
Against: Keyloggers capturing what you type, input capture via malicious overlays, reading the keyboard of other apps, apps that steal passwords while you type.
What it does: Detects overlays of other apps on top of yours. Detects suspicious accessibility services. Verifies input is not being intercepted.
What it protects: Prevents GPS spoofing and fake location.
Against: Fake GPS / Mock Location apps, apps that change your location to claim rewards from other cities, bypass geographic restrictions.
What it does: Detects if the system is in mock location mode. Detects if location providers are being faked. Detects active fake GPS apps. If fake GPS is detected, it kills the app.
What it protects: Detects VPN and Man-in-the-Middle proxies.
Against: VPNs changing your IP (region bypass), proxies intercepting the app traffic, MITM reading/modifying the communication, tunneling (OpenVPN, WireGuard, Shadowsocks, V2Ray).
What it does: Detects VPN network interfaces (tun0, wg0, pp0). Detects configured proxy connections. Detects VPN apps running on the device. Compares real IP vs server IP.
What it protects: Pins SSL certificates to prevent MITM attacks.
Against: SSL interception (Burp Suite, Charles, mitmproxy), fake certificates installed on the device, Man-in-the-Middle attacks reading your HTTPS traffic, hackers analyzing your API.
What it does: The app ONLY trusts your server's certificate/public key (pin). Rejects any other certificate even if installed on the system. Prevents a proxy from decrypting and reading the traffic.
Always recommended (basic): VM Integrity, Signature Check, Lib Injection, Remove Logs
Anti-fraud / anti-hacker (default): Anti-Hook, Anti-Debug, Anti-Emulator, Root Detection, DEX Injection, ADB Guard
Optional (depends on the app): Screen Share, Keylogger, Fake GPS, VPN/Proxy, SSL Pinning
