问题描述
我正在开发一个需要实现根检测逻辑的应用程序，因此通过研究，我在JAVA中发现了一些检测逻辑并实现了以下类。
class RootDetection {
public boolean isDeviceRooted() {
return checkForBinary("su") || checkForBinary("busyBox") || checkForMalicIoUsPaths() || checkSUonPath()
|| detectRootManagementApps() || detectpotentiallyDangerousApps() || detectRootCloakingApps()
|| checkForDangerousProps() || checkForRWPaths()
|| detectTestKeys() || checkSuExists();
}
private boolean detectTestKeys() {
String buildTags = android.os.Build.TAGS;
String buildFinger = Build.FINGERPRINT;
String product = Build.PRODUCT;
String hardware = Build.HARDWARE;
String display = Build.disPLAY;
System.out.println("Java: build: " + buildTags + "\nFingerprint: " + buildFinger + "\n Product: " + product + "\n Hardware: " + hardware + "\ndisplay: " + display);
return (buildTags != null) && (buildTags.contains("test-keys") || buildFinger.contains("genric.*test-keys") || product.contains("generic") || product.contains("sdk") || hardware.contains("goldfish") || display.contains(".*test-keys"));
}
private boolean detectRootManagementApps() {
return detectRootManagementApps(null);
}
private boolean detectRootManagementApps(String[] additionalRootManagementApps) {
ArrayList<String> packages = new ArrayList<>();
packages.addAll(Arrays.asList(kNownRootAppsPackages));
if (additionalRootManagementApps != null && additionalRootManagementApps.length > 0) {
packages.addAll(Arrays.asList(additionalRootManagementApps));
}
return isAnyPackageFromListInstalled(packages);
}
private boolean detectpotentiallyDangerousApps() {
return detectpotentiallyDangerousApps(null);
}
private boolean detectpotentiallyDangerousApps(String[] additionalDangerousApps) {
ArrayList<String> packages = new ArrayList<>();
packages.addAll(Arrays.asList(kNownDangerousAppsPackages));
if (additionalDangerousApps != null && additionalDangerousApps.length > 0) {
packages.addAll(Arrays.asList(additionalDangerousApps));
}
return isAnyPackageFromListInstalled(packages);
}
private boolean detectRootCloakingApps() {
return detectRootCloakingApps(null);
}
private boolean detectRootCloakingApps(String[] additionalRootCloakingApps) {
ArrayList<String> packages = new ArrayList<>();
packages.addAll(Arrays.asList(kNownRootCloakingPackages));
if (additionalRootCloakingApps != null && additionalRootCloakingApps.length > 0) {
packages.addAll(Arrays.asList(additionalRootCloakingApps));
}
return isAnyPackageFromListInstalled(packages);
}
private boolean checkForBinary(String filename) {
for (String path : suPaths) {
String completePath = path + filename;
File f = new File(completePath);
boolean fileExists = f.exists();
if (fileExists) {
return true;
}
}
return false;
}
private boolean checkForMalicIoUsPaths() {
for (String path : malicIoUsPaths) {
File f = new File(path);
boolean fileExists = f.exists();
if (fileExists) {
return true;
}
}
return false;
}
private static boolean checkSUonPath() {
for (String pathDir : System.getenv("PATH").split(":")) {
if (new File(pathDir,"su").exists()) {
return true;
}
}
return false;
}
private String[] propsReader() {
InputStream inputstream = null;
try {
inputstream = Runtime.getRuntime().exec("getprop").getInputStream();
} catch (IOException e) {
e.printstacktrace();
}
String propval = "";
try {
propval = new Scanner(inputstream).useDelimiter("\\A").next();
} catch (NoSuchElementException e) {
}
return propval.split("\n");
}
private String[] mountReader() {
InputStream inputstream = null;
try {
inputstream = Runtime.getRuntime().exec("mount").getInputStream();
} catch (IOException e) {
e.printstacktrace();
}
if (inputstream == null) return null;
String propval = "";
try {
propval = new Scanner(inputstream).useDelimiter("\\A").next();
} catch (NoSuchElementException e) {
e.printstacktrace();
}
return propval.split("\n");
}
private boolean isAnyPackageFromListInstalled(List<String> packages) {
PackageManager pm = activity.getPackageManager();
for (String packageName : packages) {
try {
pm.getPackageInfo(packageName,0);
return true;
} catch (PackageManager.NameNotFoundException e) {
}
}
return false;
}
private boolean checkForDangerousProps() {
final Map<String,String> dangerousProps = new HashMap<>();
dangerousProps.put("ro.debuggable","1");
dangerousProps.put("ro.secure","0");
String[] lines = propsReader();
for (String line : lines) {
for (String key : dangerousProps.keySet()) {
if (line.contains(key)) {
String badValue = dangerousProps.get(key);
badValue = "[" + badValue + "]";
if (line.contains(badValue)) {
return true;
}
}
}
}
return false;
}
private boolean checkForRWPaths() {
String[] lines = mountReader();
for (String line : lines) {
String[] args = line.split(" ");
if (args.length < 4) {
continue;
}
String mountPoint = args[1];
String mountOptions = args[3];
for (String pathtocheck : pathsThatShouldNotBeWrtiable) {
if (mountPoint.equalsIgnoreCase(pathtocheck)) {
for (String option : mountOptions.split(",")) {
if (option.equalsIgnoreCase("rw")) {
return true;
}
}
}
}
}
return false;
}
private boolean checkSuExists() {
Process process = null;
try {
process = Runtime.getRuntime().exec(new String[]{"which","su"});
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
return in.readLine() != null;
} catch (Throwable t) {
return false;
} finally {
if (process != null) process.destroy();
}
}
}
但是现在为了提高安全性，我想在本机C ++ JNI代码中执行此根检测逻辑。我设法将程序包检测代码迁移到JNI C，但是找不到关于这3个功能的任何信息
checkForDangerousProps（），checkForRWPaths（），checkSuExists（）
这3个使用无法找到的Runtime.getRuntime（）。exec。有人可以从上述代码中帮助我将这三种逻辑转换为JNI C吗？帮助将不胜感激。
请大家帮忙。
