ios - 在 iOS 11 或更高版本中检测越狱

Question

使用了“https://github.com/leecrossley/cordova-plugin-jailbreak-detection”但它仍然没有检查越狱，因为 Cydia 和其他选项在最新的 11+ iOS 版本中被绕过了

如何使用 Cordova 或 native 代码处理最新的 iOS？

2021 年更新:您可以使用本文中 UIDevice 上的扩展: https://developerinsider.co/best-way-to-check-if-your-ios-app-is-running-on-a-jailbroken-phone/

我在这里复制了所有代码。

您可以在 Github 上找到最新版本的代码(作者是@vinetchoudhary): https://github.com/developerinsider/isJailBroken/blob/master/IsJailBroken/Extension/UIDevice%2BJailBroken.swift

完整代码:

import Foundation
import UIKit

extension UIDevice {
    var isSimulator: Bool {
        return TARGET_OS_SIMULATOR != 0
    }
    
    var isJailBroken: Bool {
        get {
            if UIDevice.current.isSimulator { return false }
            if JailBrokenHelper.hasCydiaInstalled() { return true }
            if JailBrokenHelper.isContainsSuspiciousApps() { return true }
            if JailBrokenHelper.isSuspiciousSystemPathsExists() { return true }
            return JailBrokenHelper.canEditSystemFiles()
        }
    }
}
    
private struct JailBrokenHelper {
    static func hasCydiaInstalled() -> Bool {
        return UIApplication.shared.canOpenURL(URL(string: "cydia://")!)
    }
    
    static func isContainsSuspiciousApps() -> Bool {
        for path in suspiciousAppsPathToCheck {
            if FileManager.default.fileExists(atPath: path) {
                return true
            }
        }
        return false
    }
    
    static func isSuspiciousSystemPathsExists() -> Bool {
        for path in suspiciousSystemPathsToCheck {
            if FileManager.default.fileExists(atPath: path) {
                return true
            }
        }
        return false
    }
    
    static func canEditSystemFiles() -> Bool {
        let jailBreakText = "Developer Insider"
        do {
            try jailBreakText.write(toFile: jailBreakText, atomically: true, encoding: .utf8)
            return true
        } catch {
            return false
        }
    }
    
    /**
     Add more paths here to check for jail break
     */
    static var suspiciousAppsPathToCheck: [String] {
        return ["/Applications/Cydia.app",
                "/Applications/blackra1n.app",
                "/Applications/FakeCarrier.app",
                "/Applications/Icy.app",
                "/Applications/IntelliScreen.app",
                "/Applications/MxTube.app",
                "/Applications/RockApp.app",
                "/Applications/SBSettings.app",
                "/Applications/WinterBoard.app"
        ]
    }
    
    static var suspiciousSystemPathsToCheck: [String] {
        return ["/Library/MobileSubstrate/DynamicLibraries/LiveClock.plist",
                "/Library/MobileSubstrate/DynamicLibraries/Veency.plist",
                "/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",
                "/System/Library/LaunchDaemons/com.ikey.bbot.plist",
                "/System/Library/LaunchDaemons/com.saurik.Cydia.Startup.plist",
                "/usr/bin/sshd",
                "/usr/libexec/sftp-server",
                "/usr/sbin/sshd",
                "/etc/apt",
                "/bin/bash",
                "/Library/MobileSubstrate/MobileSubstrate.dylib"
        ]
    }
}

此外，您需要在 Info.plist 内的 LSApplicationQueriesSchemes 键中添加 cydia。 canOpenURL 需要它才能工作。

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>cydia</string>
</array>
