APK加固。该项目包含了对加固后的apk进行dex解密和加载 5 | 6 | ## 一、生成 Shell.aar(dex 解密和类加载) 7 | 8 | ### 1、解密加固的 dex 文件的流程 9 | 1. 在 Application 中可以通过 getApplicationInfo().sourceDir 来获取 base APK，这个 apk 就包含了我们应用的所有代码。 10 | 2. 通过 Application 的getDir() 方法，我们在应用的私有目录创建一个私有文件夹 SteadyDir 11 | 3. 在 2 中创建的目录里面我们将 bask.apk 解压 12 | 4. 解压后我们得到 apk 的所有文件，然后过滤出所有以dex为后缀的文件。其中 classes.dex 文件我们不需要因为它已经被加载进系统，所以只需要处理被我们加密的dex 文件 13 | 5. 将解密后的 dex 文件加载到程序中 14 | 6. 运行 apk 真实的 application，启动 app 15 | 16 | ### 2、如何解压 apk 文件 17 | 18 | zip 解压主要用到了 java 中的 ZipFile 类，具体实现直接上代码，代码中包含注释就不多解释。 19 | 20 | ```java 21 | public static void unZip(File zip, File dir) { 22 | try { 23 | //清空存放解压文件的目录 24 | deleteFile(dir); 25 | ZipFile zipFile = new ZipFile(zip); 26 | //zip文件中每一个条目 27 | Enumeration entries = zipFile.entries(); 28 | //遍历 29 | while (entries.hasMoreElements()) { 30 | ZipEntry zipEntry = entries.nextElement(); 31 | //zip中 文件/目录名 32 | String name = zipEntry.getName(); 33 | //原来的签名文件 不需要了 34 | if (name.equals("META-INF/CERT.RSA") || name.equals("META-INF/CERT.SF") || name 35 | .equals("META-INF/MANIFEST.MF")) { 36 | continue; 37 | } 38 | //空目录不管 39 | if (!zipEntry.isDirectory()) { 40 | File file = new File(dir, name); 41 | //创建目录 42 | if (!file.getParentFile().exists()) { 43 | file.getParentFile().mkdirs(); 44 | } 45 | //写文件 46 | FileOutputStream fos = new FileOutputStream(file); 47 | InputStream is = zipFile.getInputStream(zipEntry); 48 | byte[] buffer = new byte[2048]; 49 | int len; 50 | while ((len = is.read(buffer)) != -1) { 51 | fos.write(buffer, 0, len); 52 | } 53 | is.close(); 54 | fos.close(); 55 | } 56 | } 57 | zipFile.close(); 58 | } catch (Exception e) { 59 | e.printStackTrace(); 60 | } 61 | } 62 | 63 | 64 | private static void deleteFile(File file){ 65 | if (file.isDirectory()){ 66 | File[] files = file.listFiles(); 67 | for (File f: files) { 68 | deleteFile(f); 69 | } 70 | }else{ 71 | file.delete(); 72 | } 73 | } 74 | ``` 75 | 76 | ### 3、如何解密 dex 文件 77 | 78 | 通过第二步中的解压方式，我们可以很轻松的将 base.apk 解压到私有目录下。然后我们通过文件的后缀名.dex 过滤出所有 dex 文件（排除 classes.dex），接着读取每个 dex 到字节数组中，然后对字节数组进行解密操作。 79 | 这里加解密使用的是 AES 的方式，为了增加安全性这里将解密的方式用 jni 方式完成。解密方式如下： 80 | 81 | ```c++ 82 | jbyteArray decrypt(JNIEnv *env,jbyteArray srcData) { 83 | jstring type = (*env).NewStringUTF("AES"); 84 | jstring cipher_mode = (*env).NewStringUTF("AES/ECB/PKCS5Padding"); 85 | jbyteArray pwd = (*env).NewByteArray(16); 86 | char *master_key = (char *) "huangdh'l,.AMWK;"; 87 | (*env).SetByteArrayRegion(pwd,0,16,reinterpret_cast(master_key)); 88 | 89 | jclass secretKeySpecClass = (*env).FindClass("javax/crypto/spec/SecretKeySpec"); 90 | jmethodID secretKeySpecMethodId = (*env).GetMethodID(secretKeySpecClass,"", "([BLjava/lang/String;)V"); 91 | jobject secretKeySpecObj = (*env).NewObject(secretKeySpecClass,secretKeySpecMethodId,pwd,type); 92 | 93 | jclass cipherClass = (*env).FindClass("javax/crypto/Cipher"); 94 | jmethodID cipherInitMethodId = (*env).GetMethodID(cipherClass,"init", "(ILjava/security/Key;)V"); 95 | jmethodID cipherInstanceMethodId = (*env).GetStaticMethodID(cipherClass,"getInstance", "(Ljava/lang/String;)Ljavax/crypto/Cipher;"); 96 | jobject cipherObj = (*env).CallStaticObjectMethod(cipherClass,cipherInstanceMethodId,cipher_mode); 97 | 98 | jfieldID decryptModeFieldId = (*env).GetStaticFieldID(cipherClass,"DECRYPT_MODE", "I"); 99 | jint mode = (*env).GetStaticIntField(cipherClass,decryptModeFieldId); 100 | (*env).CallVoidMethod(cipherObj,cipherInitMethodId,mode,secretKeySpecObj); 101 | 102 | jmethodID doFinalMethodId = (*env).GetMethodID(cipherClass,"doFinal", "([B)[B"); 103 | jbyteArray text = (jbyteArray)(*env).CallObjectMethod(cipherObj,doFinalMethodId,srcData); 104 | return text; 105 | } 106 | ``` 107 | 108 | ### 4、加载 dex 文件 109 | 通过上面的解压和解密操作我们得到了原始的 dex 文件，我们将这些dex文件放进一个集合中,接下来使用类加载机制加载已经解密后的 dex 文件。关于类加载机制会在后续文章中讲解。 110 | ```java 111 | public static void loadDex(Application application,List dexFiles, File versionDir) throws Exception{ 112 | //1.先从 ClassLoader 中获取 pathList 的变量 113 | Field pathListField = ProxyUtils.findField(application.getClassLoader(), "pathList"); 114 | //1.1 得到 DexPathList 类 115 | Object pathList = pathListField.get(application.getClassLoader()); 116 | //1.2 从 DexPathList 类中拿到 dexElements 变量 117 | Field dexElementsField= ProxyUtils.findField(pathList,"dexElements"); 118 | //1.3 拿到已加载的 dex 数组 119 | Object[] dexElements=(Object[])dexElementsField.get(pathList); 120 | 121 | //2. 反射到初始化 dexElements 的方法，也就是得到加载 dex 到系统的方法 122 | Method makeDexElements= ProxyUtils.findMethod(pathList,"makePathElements",List.class,File.class,List.class); 123 | //2.1 实例化一个 集合 makePathElements 需要用到 124 | ArrayList suppressedExceptions = new ArrayList(); 125 | //2.2 反射执行 makePathElements 函数，把已解码的 dex 加载到系统，不然是打不开 dex 的，会导致 crash 126 | Object[] addElements=(Object[])makeDexElements.invoke(pathList,dexFiles,versionDir,suppressedExceptions); 127 | 128 | //3. 实例化一个新数组，用于将当前加载和已加载的 dex 合并成一个新的数组 129 | Object[] newElements= (Object[]) Array.newInstance(dexElements.getClass().getComponentType(),dexElements.length+addElements.length); 130 | //3.1 将系统中的已经加载的 dex 放入 newElements 中 131 | System.arraycopy(dexElements,0,newElements,0,dexElements.length); 132 | //3.2 将解密后已加载的 dex 放入新数组中 133 | System.arraycopy(addElements,0,newElements,dexElements.length,addElements.length); 134 | 135 | //4. 将合并的新数组重新设置给 DexPathList的 dexElements 136 | dexElementsField.set(pathList,newElements); 137 | } 138 | ``` 139 | ### 5、加载真实的 application 类，运行 app 140 | 1、首先从 AndroidManifest.xml 文件中获取到原 application 的类名。（在下一篇文章中会讲解我们如何将 apk 的原来的 application 类名放到 AndroidManifest.xml 的meta-data 标签下） 141 | ```java 142 | /** 143 | * 解析项目中原来的 Application 名称 144 | */ 145 | private void getMateData(){ 146 | try{ 147 | ApplicationInfo applicationInfo = getPackageManager().getApplicationInfo(getPackageName(), 148 | PackageManager.GET_META_DATA);//获取包信息 149 | Bundle metaData = applicationInfo.metaData;//获取 Meta-data 的键值对信息 150 | if(null != metaData){ 151 | if(metaData.containsKey("app_name")){ 152 | app_name = metaData.getString("app_name");//获取原来的包名 153 | } 154 | } 155 | }catch (Exception e){ 156 | e.printStackTrace(); 157 | } 158 | } 159 | ``` 160 | 2、获取到原 application 的类名后就通过反射获取到 application 的实例。 161 | ``` 162 | private void bindRealApplication() throws Exception{ 163 | if(isBindReal){ 164 | return; 165 | } 166 | if(TextUtils.isEmpty(app_name)){ 167 | return; 168 | } 169 | //1、得到 attachBaseContext(context)传入的上下文 ContextImpl 170 | Context baseContext = getBaseContext(); 171 | //2、拿到真实 APK Application 的 class 172 | Class delegateClass = Class.forName(app_name); 173 | //反射实例化， 174 | delegate = (Application) delegateClass.newInstance(); 175 | //得到 Application attach() 方法 也就是最先初始化的 176 | Method attach = Application.class.getDeclaredMethod("attach",Context.class); 177 | attach.setAccessible(true); 178 | //执行 Application#attach(Context) 179 | attach.invoke(delegate,baseContext); 180 | 181 | // ContextImpl---->mOuterContext(app) 通过Application的attachBaseContext回调参数获取 182 | //4. 拿到 Context 的实现类 183 | Class contextImplClass = Class.forName("android.app.ContextImpl"); 184 | //4.1 获取 mOuterContext Context 属性 185 | Field mOuterContextField = contextImplClass.getDeclaredField("mOuterContext"); 186 | mOuterContextField.setAccessible(true); 187 | //4.2 将真实的 Application 交于 Context 中。这个根据源码执行，实例化 Application 下一个就行调用 setOuterContext 函数，所以需要绑定 Context 188 | // app = mActivityThread.mInstrumentation.newApplication( 189 | // cl, appClass, appContext); 190 | // appContext.setOuterContext(app); 191 | mOuterContextField.set(baseContext, delegate); 192 | 193 | // ActivityThread--->mAllApplications(ArrayList) ContextImpl的mMainThread属性 194 | //5. 拿到 ActivityThread 变量 195 | Field mMainThreadField = contextImplClass.getDeclaredField("mMainThread"); 196 | mMainThreadField.setAccessible(true); 197 | //5.1 拿到 ActivityThread 对象 198 | Object mMainThread = mMainThreadField.get(baseContext); 199 | 200 | // ActivityThread--->>mInitialApplication 201 | //6. 反射拿到 ActivityThread class 202 | Class activityThreadClass=Class.forName("android.app.ActivityThread"); 203 | //6.1 得到当前加载的 Application 类 204 | Field mInitialApplicationField = activityThreadClass.getDeclaredField("mInitialApplication"); 205 | mInitialApplicationField.setAccessible(true); 206 | //6.2 将 ActivityThread 中的 Applicaiton 替换为 真实的 Application 可以用于接收相应的声明周期和一些调用等 207 | mInitialApplicationField.set(mMainThread,delegate); 208 | 209 | 210 | // ActivityThread--->mAllApplications(ArrayList) ContextImpl的mMainThread属性 211 | //7. 拿到 ActivityThread 中所有的 Application 集合对象，这里是多进程的场景 212 | Field mAllApplicationsField = activityThreadClass.getDeclaredField("mAllApplications"); 213 | mAllApplicationsField.setAccessible(true); 214 | ArrayList mAllApplications =(ArrayList) mAllApplicationsField.get(mMainThread); 215 | //7.1 删除 ProxyApplication 216 | mAllApplications.remove(this); 217 | //7.2 添加真实的 Application 218 | mAllApplications.add(delegate); 219 | 220 | // LoadedApk------->mApplication ContextImpl的mPackageInfo属性 221 | //8. 从 ContextImpl 拿到 mPackageInfo 变量 222 | Field mPackageInfoField = contextImplClass.getDeclaredField("mPackageInfo"); 223 | mPackageInfoField.setAccessible(true); 224 | //8.1 拿到 LoadedApk 对象 225 | Object mPackageInfo=mPackageInfoField.get(baseContext); 226 | 227 | //9 反射得到 LoadedApk 对象 228 | // @Override 229 | // public Context getApplicationContext() { 230 | // return (mPackageInfo != null) ? 231 | // mPackageInfo.getApplication() : mMainThread.getApplication(); 232 | // } 233 | Class loadedApkClass=Class.forName("android.app.LoadedApk"); 234 | Field mApplicationField = loadedApkClass.getDeclaredField("mApplication"); 235 | mApplicationField.setAccessible(true); 236 | //9.1 将 LoadedApk 中的 Application 替换为 真实的 Application 237 | mApplicationField.set(mPackageInfo,delegate); 238 | 239 | //修改ApplicationInfo className LooadedApk 240 | 241 | //10. 拿到 LoadApk 中的 mApplicationInfo 变量 242 | Field mApplicationInfoField = loadedApkClass.getDeclaredField("mApplicationInfo"); 243 | mApplicationInfoField.setAccessible(true); 244 | //10.1 根据变量反射得到 ApplicationInfo 对象 245 | ApplicationInfo mApplicationInfo = (ApplicationInfo)mApplicationInfoField.get(mPackageInfo); 246 | //10.2 将我们真实的 APPlication ClassName 名称赋值于它 247 | mApplicationInfo.className=app_name; 248 | 249 | //11. 执行 代理 Application onCreate 声明周期 250 | delegate.onCreate(); 251 | 252 | //解码完成 253 | isBindReal = true; 254 | 255 | } 256 | ``` 257 | 至此 apk 的解密便结束了 258 | 259 | #### 参与贡献 260 | 261 | 1.
