Question

在我的应用中，我想检测设备是否已越狱。如果已越狱，则不应允许用户使用该应用。我添加了一个功能来检测但不能检测越狱设备

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Appdelegate.m（Obj c）

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

从iOS 14开始，应用无法在其捆绑包中进行这些fs检查，因此您上面的方法将不起作用。

此外，越狱检测是不值得的，可以将该检查修补为最多仅使用6条线就不能使用，这是人们需要停止战斗的败仗。

越狱检测机制未检测到越狱设备
