IntegritySwift

An unified product for check many topics about integrity & security.

Installation

[Add the Swift Package to your project from url: https://github.com/CodeNationDev/IntegritySwift.git

Definition & Interface

This product has been developd as class type with @objc flags for allow the usage from swift and ObjC.

@objc public static var isSecure: Bool

When you request the value of this variable, the result (true/false) is generated besed on all security checks passed in that moment.

@objc public static var globalControlsResults: [SecurityResult]

This object return an array with the object (defined at models file) that contains the results of all checks evaluated, and it have following structure:

@objc public enum SecurityControlType: Int {
    case jailbreak = 0
    case simulator = 1
    case debugger = 2
    case reverse = 3
}

@objc public class SecurityResult: NSObject {
    @objc public var passed: Bool = true
    @objc public var reason: String = ""
    @objc public var type: SecurityControlType
    
    @objc public init(_ passed: Bool, _ reason: String, _ type: SecurityControlType) {
        self.passed = passed
        self.reason = reason
        self.type = type
    }
}

Also, you can request the state of any individual check of all available.

Jailbreak

Global Jailbreak passchecks

@objc public static var isDeviceJailbroken: Bool

The object array with check results.

@objc public static var jailbreakControlsResults: [SecurityResult]

Sandbox violation passcheck. Check existence of files that are common for jailbroken devices

@objc public static func jailbreakSuspiciousFilesCheck() -> SecurityResult

If we can execute a Cyda urlScheme, the device is jailbroken

@objc public static func jailbreakUrlSchemes() -> SecurityResult

This check looks for the exist of suspicious dylibs.

@objc public static func jailbreakDYLD() -> SecurityResult

This check detects a forked proccess.

public static func jailbreakFork() -> SecurityResult

Debugger state

Global Debugger state passchecks

@objc public static func amIDebugged() -> SecurityResult

Function for deny debug mode

@objc public static func denyDebugger()

Reverse Engineering

Global checks for Reverse Engineering

@objc public static func amIReverseEngineered() -> Bool

The object array with check results.

public static var antiReverseControlsResults: [SecurityResult]

Checks for suspicious libraries.

public static func checkDYLD() -> SecurityResult

Check suspicious files

public static func checkExistenceOfSuspiciousFiles() -> SecurityResult

Check opened ports

public static func checkOpenedPorts() -> SecurityResult

Check if we can open a local connection in a specific port.

public static func canOpenLocalConnection(port: Int) -> SecurityResult

Simulator

Global check for simulatoir discoverer.

@objc public static func isRunningInSimulator() -> Bool

Usage example

Simply get the isSecure value:

Swift

//
import UIKit
import IntegirtySwift

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        if !IntegrityManager.isSecure {
            //do something if device device is not secure.
        }
        
        if !JailbreakDiscoverer.isDeviceJailbroken {
            //do something if device jailbroken
        }
        
        if DebuggerDiscoverer.amIDebugged().passed {
            //do something if the device is a simulator
        }
        
        return true
    }

Objetive-C

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if (!SecurityManager.isSecure) {
      //do something if device is not secure.
    }
}
