Remove Zimperium and InAuth SDK

Perform the following steps to remove the legacy Zimperium inAuth SDK from your iOS and Android project:

Android

Remove obsolete binaries

• Remove the zdetection.aar file in the app/libs folder.
• Remove the shared libraries, libLIB-v3.8.2.so.

Update your gradle build script

Remove the link to the zdetection.aar file in the application's gradle build script.

• Old content

  dependencies {
      implementation "com.android.support:appcompat-v7:28.0.0"
  
      // Add Risk Management Platform java library
      releaseImplementation files("libs/release/GAHRiskEngine.jar")
      debugImplementation files("libs/debug/GAHRiskEngine.jar")
  
      // Add ZDetection java library
      implementation files("libs/zdetection@aar")
  
      // other config ...
  }
  

• New content

  dependencies {
      implementation "com.android.support:appcompat-v7:28.0.0"
  
      // Add Risk Management Platform java library
      releaseImplementation files("libs/release/GAHRiskEngine.jar")
      debugImplementation files("libs/debug/GAHRiskEngine.jar")
  
      // other config ...
  }
  

Update the source code

These classes are no longer available. You can update the application source code to remove them:

• GAHINAConfig
• GAHZMPConfig

Clean up obsolete files and folders

By removing the Zimperium & InAuth modules, the application can do a clean up of the obsolete files and folders created inside the application storage to save space.

Here is the list of files and folders that can be removed:

• databases/zdetection.db
• databases/zdetection.db-journal
• shared_prefs/zcloud.xml
• shared_prefs/zcore_stats.xml
• shared_prefs/zdebug_log_2.xml
• shared_prefs/zdetection_urls.xml
• shared_prefs/ziap_features.xml
• shared_prefs/ziap_version.xml
• files/mob
• files/*.zee9
• files/*.lookup
• files/zdb.bin
• files/zdb-blackwhitelist.bin

Here is a sample of implementation to remove those files and folders:

private void cleanUpFile(Context context) {
    boolean error = false;

    // List of common files
    List<String> FILES_TO_REMOVE_1 = Arrays.asList(
            "databases/zdetection.db",
            "databases/zdetection.db-journal",

            "shared_prefs/zcloud.xml",
            "shared_prefs/zcore_stats.xml",
            "shared_prefs/zdebug_log_2.xml",
            "shared_prefs/zdetection_urls.xml",
            "shared_prefs/ziap_features.xml",
            "shared_prefs/ziap_version.xml"
    );

    // Data inside "files" folder
    String FILES_TO_REMOVE_2 = "mob";
    List<String> FILES_TO_REMOVE_3 = Arrays.asList(
            ".lookup",
            ".zee9",

            "zdb.bin",
            "zdb-blackwhitelist.bin"
    );

    // Deleting common files
    File based = context.getFilesDir().getParentFile();
    for (String file : FILES_TO_REMOVE_1) {
        File f = new File(based, file);
        f.delete();
    }

    // Deleting folder inside "files"
    try {
        Runtime.getRuntime().exec("rm -rf " + FILES_TO_REMOVE_2,
                null,
                context.getFilesDir()
        );
    } catch (Exception ex) {
        ex.printStackTrace();
        Log.e(TAG, "Failed to remove data: " + FILES_TO_REMOVE_2);
        error = true;
    }

    // Deleting files with specific name
    File[] files = context.getFilesDir().listFiles((File file) -> {
        boolean accepted = false;
        for (String name : FILES_TO_REMOVE_3)
            if (file.getName().endsWith(name)) {
                accepted = true;
                break;
            }

        return accepted;
    });
    if (files != null) {
        for (File f : files)
            f.delete();
    }

    if (error)
        Log.e(TAG, "Failed to remove data file!");
    else
        Log.w(TAG, "Old data files have been removed!");
}

iOS

Remove obsolete frameworks

• Remove the Zdetection.framework file in the Xcode project.

• Remove the value $(SRCROOT)/../../Frameworks/ZDetection set in the framework search path in Settings > FRAMEWORK_SEARCH_PATHS.

Remove obsolete permissions

The NSLocalNetworkUsageDescription permission can be removed from your application’s Info.plist, unless it is needed by another application component. It was previously requested from Zimperium.

Update the source code

These configuration classes are no longer available. You can update the application source code to remove them:

• GAHINAConfig
• GAHZMPConfig

Clean up obsolete files and folders

By removing the Zimperium and InAuth modules, the application can do a clean up of the obsolete files and folders created inside the application storage, to save space.

Here is the list of obsolete files under the Documents folder that can be removed:

• ZDetection.sqlite
• ZDetection.sqlite-shm
• ZDetection.sqlite-wal
• trm.bin
• trm.dat
• trm_severity.dat
• zcore_full.zee9
• zcore_zphish.fdeep
• zcore_zphish.zee9
• zdb.bin

Here is a sample of implementation to remove those files and folders:

- (void)clearObsoletedDataFromPreviousVersion
{
    NSString *documentDirectory = [[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] objectAtIndex:0] path];

    NSArray *obsoletedFiles = [NSArray arrayWithObjects:@"ZDetection.sqlite", @"ZDetection.sqlite-shm", @"ZDetection.sqlite-wal", @"trm.bin", @"trm.dat", @"trm_severity.dat", @"zcore_full.zee9", @"zcore_zphish.fdeep", @"zcore_zphish.zee9", @"zdb.bin", nil];

    for (NSString *file in obsoletedFiles) {
        NSString *resource = [documentDirectory stringByAppendingPathComponent:file];
        [self removeDirectoryOrFileIfExists:resource];
    }
}

- (void)removeDirectoryOrFileIfExists:(NSString *)path
{
    if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {
        [[NSFileManager defaultManager] removeItemAtPath:path error:nil];
    }
}
