Detect jailbroken bypass in Xamarin forms - xamarin.forms

Question

My Xamarin based iOS application should not run in jailbroken devices. This is due to a IS audit. I have implemented the jailbroken detect mechanism. But I cannot find a way to detect whether someone using a jailbroken bypass method like for example A-bypass, shadow tweaks. Anyone with these tweaks can easily by pass the jailbroken detect code.
This is the class I used,
[assembly: Dependency(typeof(CheckHardware))]
namespace CustApp.iOS
{
public class CheckHardware : IHardwareSecurity
{
public CheckHardware()
{
}
public bool IsJailBreaked()
{
if (isPath() || canCreateFile() || isOpenLink())
{
return true;
}
else
{
return false;
}
}
private bool isPath()
{
bool res = false;
List<string> pathList = new List<string>
{
"/Applications/Cydia.app",
"/Applications/Checkra1n.app",
"/Applications/FakeCarrier.app",
"/Applications/Icy.app",
"/Applications/IntelliScreen.app",
"/Applications/MxTube.app",
"/Applications/RockApp.app",
"/Applications/SBSettings.app",
"/Applications/WinterBoard.app",
"/Applications/blackra1n.app",
"/Library/MobileSubstrate/DynamicLibraries/LiveClock.plist",
"/Library/MobileSubstrate/DynamicLibraries/Veency.plist",
"/Library/MobileSubstrate/MobileSubstrate.dylib",
"/System/Library/LaunchDaemons/com.ikey.bbot.plist",
"/System/Library/LaunchDaemons/com.saurik.Cydia.Startup.plist",
"/etc/apt",
"/private/var/lib/apt",
"/private/var/lib/apt/",
"/private/var/lib/cydia",
"/private/var/mobile/Library/SBSettings/Themes",
"/private/var/stash",
"/private/var/tmp/cydia.log",
"/usr/bin/sshd",
"/var/cache/apt",
"/var/lib/apt",
"/usr/libexec/sftp-server",
"/usr/sbin/sshd",
"/bin/bash",
"/Library/MobileSubstrate/MobileSubstrate.dylib",
"/var/lib/cydia"
};
foreach (var fullPath in pathList)
{
if (File.Exists(fullPath))
{
res = true;
}
}
return res;
}
private bool canCreateFile()
{
try
{
File.WriteAllText("/private/jailbreak.txt", "This is a test.");
return true;
}
catch (UnauthorizedAccessException)
{
return false;
}
}
private bool isOpenLink()
{
if (UIApplication.SharedApplication.CanOpenUrl(NSUrl.FromString("cydia://package/com.example.package")))
{
return true;
}
else
{
return false;
}
}
public bool IsInEmulator()
{
bool isSimulator = Runtime.Arch == Arch.SIMULATOR;
return isSimulator;
}
}
}
