[移动开发]Android-Xposed检测，断网检测，模拟器检测，VPN代理抓包检测

前言

这些是从其他软件逆向出来的四种检测手段，能不能用暂时没试过，但是逆向之前是能用的。

正文

  1. Xposed检测（XposedDetect）
    检测到Xposed环境就强制闪退
    public static boolean XposedDetect(){
		if (checkXpFormMap()) {
            System.exit(1);
        }
        if (isHookByStack()) {
            System.exit(1);
        }
		return false;
	}

	private static boolean isHookByStack() {
        boolean isHook = false;
        try {
            throw new Exception("blah");
        } catch (Exception e) {
            int zygoteInitCallCount = 0;
            StackTraceElement[] stackTrace = e.getStackTrace();
            for (StackTraceElement stackTraceElement : stackTrace) {
                if (stackTraceElement.getClassName().equals("com.android.internal.os.ZygoteInit") && (zygoteInitCallCount = zygoteInitCallCount + 1) == 2) {
                    isHook = true;
                }
                if (stackTraceElement.getClassName().equals("com.saurik.substrate.MS$2") && stackTraceElement.getMethodName().equals("invoked")) {
                    isHook = true;
                }
                if (stackTraceElement.getClassName().equals("de.robv.android.xposed.XposedBridge") && stackTraceElement.getMethodName().equals("main")) {
                    isHook = true;
                }
                if (stackTraceElement.getClassName().equals("de.robv.android.xposed.XposedBridge") && stackTraceElement.getMethodName().equals("handleHookedMethod")) {
                    isHook = true;
                }
            }
            return isHook;
        }
    }

    private static boolean checkXpFormMap() {
        File maps;
        String readLine;
        int Pid = Process.myPid();
        if (Pid < 0) {
            maps = new File("/proc/self/maps");
        } else {
            maps = new File("/proc/" + Pid + "/maps");
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(maps)));
            do {
                readLine = reader.readLine();
                if (readLine == null) {
                    return false;
                }
                if (readLine.contains("libdexposed") || readLine.contains("libsubstrate.so") || readLine.contains("libepic.so")) {
                    return true;
                }
            } while (!readLine.contains("libxposed"));
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return true;
        }
    }
  1. 断网检测（NetworkDetect）
    无网络就强制闪退
    public static boolean NetworkDetect(Context context){
		if (!isNetworkStatus((Context) Objects.requireNonNull(context))) {
            System.exit(0);
        }
        if (!isNetworkConnected((Context) Objects.requireNonNull(context))) {
            System.exit(0);
        }
		return false;
	}

	private static boolean isNetworkConnected(Context context) {
        NetworkInfo activeNetworkInfo = ((ConnectivityManager) context.getSystemService("connectivity")).getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting();
    }

    private static boolean isNetworkStatus(Context context) {
        NetworkInfo activeNetworkInfo;
        if (context == null || (activeNetworkInfo = ((ConnectivityManager) context.getSystemService("connectivity")).getActiveNetworkInfo()) == null) {
            return false;
        }
        return activeNetworkInfo.isAvailable();
    }
  1. 模拟器检测（SimulatorDetect）
    检测当前是否运行在安卓模拟器环境
    public static boolean SimulatorDetect(Context context){
		if (isEmulator(context)) {
            System.exit(1);
            throw new RuntimeException();
        } else if (!isEmulatorAbsoluly(context)) {
            return false;
        } else {
            System.exit(1);
            throw new RuntimeException();
        }
	}

	private static int rating = -1;

	private static boolean isEmulatorAbsoluly(Context context) {

    }
  1. VPN代理抓包检测（VpnDetect）
    检测是否开启VPN代理或者HttpCanary抓包
    public static boolean VpnDetect(Context context){
		if (isVpnConnected() || isWifiProxy(context)) {

        int proxyPort;
        if (Build.VERSION.SDK_INT >= 14) {
            proxyAddress = System.getProperty("http.proxyHost");
            String portStr = System.getProperty("http.proxyPort");
            if (portStr == null) {
                portStr = "-1";
            }
            proxyPort = Integer.parseInt(portStr);
        } else {

            proxyPort = Proxy.getPort(mContext);
        }
        if (TextUtils.isEmpty(proxyAddress) || proxyPort == -1) {
            return false;
        }
        return true;
    }

    private static boolean isVpnConnected() {
        try {
            Enumeration<NetworkInterface> niList = NetworkInterface.getNetworkInterfaces();
            if (niList == null) {

            }
            Iterator<NetworkInterface> it = Collections.list(niList).iterator();
            while (it.hasNext()) {

                }
            }

        } catch (Throwable e) {
            e.printStackTrace();
            return false;
        }
    }

别忘了权限。

    <!-- 拥有完全的网络访问权限 -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- 查看WLAN连接 -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

来个彩蛋，防截屏
防止软件被截屏
NoPhotograph.java

import android.app.Activity;
import android.app.Application;
import android.content.ContentProvider;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import java.util.Objects;

public class NoPhotograph extends ContentProvider implements Application.ActivityLifecycleCallbacks {
    public int delete(Uri uri, String str, String[] strArr) {
        return 0;
    }

    public String getType(Uri uri) {
        return null;
    }

    public Uri insert(Uri uri, ContentValues contentValues) {
        return null;
    }

    public void onActivityCreated(Activity activity, Bundle bundle) {
        activity.getWindow().setFlags(8192, 8192);
    }

    public void onActivityDestroyed(Activity activity) {
    }

    public void onActivityPaused(Activity activity) {
    }

    public void onActivityResumed(Activity activity) {
    }

    public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {
    }

    public void onActivityStarted(Activity activity) {
        activity.getWindow().setFlags(8192, 8192);
    }

	@Override
    public void onActivityStopped(Activity activity) {
    }

	@Override
    public boolean onCreate() {
        ((Application) ((Context) Objects.requireNonNull(getContext())).getApplicationContext()).registerActivityLifecycleCallbacks(this);
        return false;
    }

	@Override
    public Cursor query(Uri uri, String[] strArr, String str, String[] strArr2, String str2) {
        return null;
    }

	@Override
    public int update(Uri uri, ContentValues contentValues, String str, String[] strArr) {
        return 0;
    }
}

下面这个添加到application

        <provider
            android:name="com.software.protect.NoPhotograph"
            android:exported="false"
            android:authorities="防截屏"
            android:initOrder="19999999" />
