越狱探测机构无法检测越狱装置

Question

在我的应用程序中，我想检测设备是否被越狱。如果它是越狱，它不应该允许用户使用应用程序。我添加了一个要检测的函数，但它没有检测越狱设备。

附加代码以供参考

JailbrokenDetector.swift

func isJailBroked() -> Bool {
    let pathsArray = ["/bin/bash", "/usr/sbin/sshd", "/etc/apt", "/private/var/lib/apt/", "/Applications/Cydia.app", "/Library/MobileSubstrate/MobileSubstrate.dylib", "/Library/SBSettings/Themes/", "/System/Library/LaunchDaemons/com.saurik.Cydia.Startup.plist/", "/private/var/lib/cydia/private/var/mobile/Library/SBSettings/Themes/", "/var/cache/apt/", "/var/lib/cydia/", "/var/log/syslog/", "/var/tmp/cydia.log/", "/bin/bash/", "/bin/sh/", "/usr/sbin/sshd/", "/usr/bin/sshd/", "/usr/libexec/sftp-server/", "/etc/ssh/sshd_config/", "/etc/apt/", "/Applications/Cydia.app/", "/Applications/WinterBoard.app/", "/Applications/SBSettings.app/", "//private/var/lib/cydia/private/var/mobile/Library/SBSettings/Themes/", "/usr/libexec/ssh-keysign/", "/Applications/blackra1n.app", "/Applications/FakeCarrier.app", "/Applications/Icy.app", "/Applications/IntelliScreen.app", "/Applications/MxTube.app", "/Applications/RockApp.app", "/Library/MobileSubstrate/DynamicLibraries/LiveClock.plist", "/Library/MobileSubstrate/DynamicLibraries/Veency.plist", "/private/var/stash", "/private/var/tmp/cydia.log", "/System/Library/LaunchDaemons/com.ikey.bbot.plist"]
    
    for pathString in pathsArray {
        if FileManager.default.fileExists(atPath: pathString) {
            return true
        }
    }
            
    let dummyString = “Testing”
    
    do {
        try dummyString.write(toFile:"/private/JailbreakTest.txt", atomically:true, encoding:String.Encoding.utf8)
        return true
    } catch {
        return false
    }

  if (UIApplication.shared.canOpenURL(URL(string: "cydia://package/com.example.package")!) || UIApplication.shared.canOpenURL(URL(string: "Cydia://")!) || UIApplication.shared.canOpenURL(URL(string: "cydia://")!)) {
        return true
    }
    
    if self.canOpen(path: "/Applications/Cydia.app") ||
        self.canOpen(path: "/Library/MobileSubstrate/MobileSubstrate.dylib") ||
        self.canOpen(path: "/bin/bash") ||
        self.canOpen(path: "/usr/sbin/sshd") ||
        self.canOpen(path: "/etc/apt") ||
        self.canOpen(path: "/usr/bin/ssh") {
        return true
    }
}

在附录.m中(Obj c)

if ([JailbrokenDetector isDeviceJailBroken]) {
    exit(0);
    return NO;
}

截至iOS，14个应用程序无法在其自己的包之外执行这些fs检查，因此上面的方法将无法工作。

另外，越狱检测是不值得的，这种检查最多只能用6行就可以修补，这是一场失败的战斗，人们需要停止战斗。
