许多不幸的 iPhone 用户要求我帮助他们从 iTunes 备份中恢复数据。这在未加密时很容易,但在加密时则不然,无论密码是否已知。

因此,我试图找出加密时用于 mddata 和 mdinfo 文件的加密方案。否则我在阅读这些文件时没有任何问题,并且为此构建了一些强大的 C# 库。 (如果你能提供帮助,我不在乎你使用哪种语言。这是我在这里追求的原则!)

Apple“iPhone OS 企业部署指南”指出“设备备份可以通过选择加密 iPhone 以加密格式存储
iTunes 设备摘要 Pane 中的备份选项。文件使用 AES128 和 256 位 key 加密。 key 安全地存储在 iPhone 钥匙串(keychain)中。”

这是一个很好的线索,在 iPhone 上的 Stackoverflow 上有一些很好的信息 AES/Rijndael interoperability建议可以使用 128 的 key 大小和 CBC 模式。

除了任何其他混淆之外,还需要 key 和初始化向量 (IV)/salt。

人们可能认为 key 是对“备份密码”的操纵,iTunes 提示用户输入该密码并传递给“AppleMobileBackup.exe”,以 CBC 规定的方式填充。但是,鉴于对 iPhone 钥匙串(keychain)的引用,我想知道“备份密码”是否可能不会用作 X509 证书或对称私钥上的密码,并且证书或私钥本身可能会用作 key 。 ( AES 和 iTunes 加密/解密过程是对称的。)

IV 是另一回事,它可能是几件事。也许它是 key 之一hard-coded进入 iTunes,或进入 devices themselves .

尽管 Apple 上面的评论表明 key 存在于设备的钥匙串(keychain)上,但我认为这并不重要。人们可以将加密的备份恢复到不同的设备,这表明与解密相关的所有信息都存在于备份和 iTunes 配置中,并且在这种情况下,仅在设备上的任何内容都无关紧要且可替换。那么关键在哪里呢?

我在下面列出了来自 Windows 机器的路径,但无论我们使用哪种操作系统,它都非常重要。

“\appdata\Roaming\Apple Computer\iTunes\itunesprefs.xml”包含一个带有“Keychain”字典条目的 PList。 “\programdata\apple\Lockdown\09037027da8f4bdefdea97d706703ca034c88bab.plist”包含一个带有“DeviceCertificate”、“HostCertificate”和“RootCertificate”的PList,所有这些似乎都是有效的X509证书。同一个文件似乎还包含非对称 key “RootPrivateKey”和“HostPrivateKey”(我的阅读表明这些可能是 PKCS #7 封装的)。此外,在每个备份中,Manifest.plist 文件中都有“AuthSignature”和“AuthData”值,尽管这些值似乎随着每个文件的增量备份而轮换,表明它们作为 key 不是那么有用,除非真的相当涉及正在做。

有很多误导性的东西表明从加密备份中获取数据很容易。事实并非如此,据我所知,它还没有完成。 Bypassing or disabling备份加密完全是另一回事,这不是我想要做的。

这不是要破解 iPhone 或类似的东西。我所追求的只是一种从加密的 iTunes 备份中提取数据(照片、联系人等)的方法,就像我可以使用未加密的备份一样。我已经尝试使用上面列出的信息进行各种排列,但一无所获。我很感激我可能错过的任何想法或技术。

最佳答案

安全研究人员 Jean-Baptiste Bédrune 和 Jean Sigwald presented howto do thisHack-in-the-box Amsterdam 2011 .

此后,Apple 发布了 iOS Security Whitepaper
有关 key 和算法的更多详细信息,以及 Charlie Miller 等人。有
发布了 iOS Hacker’s Handbook ,其中涵盖了一些相同的
以操作方法为基础。当 iOS 10 首次出现时,发生了一些变化
到苹果一开始没有宣传的备份格式,但是各种
reverse-engineered the format changes .

加密备份很棒

加密的 iPhone 备份的伟大之处在于它们包含的东西
像不在常规未加密备份中的 WiFi 密码。作为
iOS Security Whitepaper 中讨论, 加密备份
被认为更“安全”,因此 Apple 认为可以包含更多
其中的敏感信息。

一个重要的警告:显然,解密你的 iOS 设备的备份
删除其加密。为了保护您的隐私和安全,你应该
仅在具有全盘加密的计算机上运行这些脚本。
虽然它
安全专家可以编写保护 key 的软件
内存,例如通过使用像 VirtualLock() 这样的函数和
SecureZeroMemory() 在许多其他事情中,这些
Python 脚本会将您的加密 key 和密码存储在字符串中
被 Python 垃圾收集。这意味着您的 key 和密码
将在 RAM 中存在一段时间,从那里它们会泄漏到您的交换中
文件并放到您的磁盘上,攻击者可以在其中恢复它们。这
完全违背了加密备份的意义。

如何解密备份:理论上

iOS Security Whitepaper解释基本概念
每个文件的 key 、保护等级、保护等级 key 和 key 包
比我能做的更好。如果你还不熟悉这些,请拿一些
分钟阅读相关部分。

现在您知道 iOS 中的每个文件都使用自己的随机数加密
每个文件的加密 key ,属于一个保护类,并且每个文件
加密 key 存储在文件系统元数据中,包装在
保护等级 key 。

解密:

  • 解码存储在 BackupKeyBag 中的 key 包进入Manifest.plist .此结构的高级概述在
    whitepaper . iPhone Wiki
    描述二进制格式:一个4字节的字符串类型字段,一个4字节的
    大端长度字段,然后是值本身。

    重要的值是 PBKDF2 ITERSALT ,双
    保护盐DPSL和迭代次数 DPIC ,然后对于每个
    保护CLS , WPKY包裹的 key 。
  • 使用备份密码使用正确的 PBKDF2 派生出一个 32 字节的 key
    盐和迭代次数。首先使用带有 DPSL 的 SHA256 轮和DPIC ,然后是 ITER 的 SHA1 回合和 SALT .

    解开每个包裹的 key
    RFC 3394 .
  • 通过从 ManifestKey 中提取 4 字节保护类和更长的 key 来解密 list 数据库。在 Manifest.plist ,并展开它。你现在有一个
    包含所有文件元数据的 SQLite 数据库。
  • 对于每个感兴趣的文件,获取类加密的每个文件加密
    查看 Files.file 中的 key 和保护类代码数据库
    包含 EncryptionKey 的二进制 plist 的列和ProtectionClass条目。剥离初始四字节长度的标签EncryptionKey使用前。

    然后,通过用类解开它来导出最终的解密 key
    用备份密码解包的 key 。然后解密文件
    在 CBC 模式下使用 AES,IV 为零。

  • 如何解密备份:在实践中

    首先,您需要一些库依赖项。如果您在使用自制安装的 Python 2.7 或 3.7 的 Mac 上,您可以使用以下命令安装依赖项:
    CFLAGS="-I$(brew --prefix)/opt/openssl/include" \
    LDFLAGS="-L$(brew --prefix)/opt/openssl/lib" \
    pip install biplist fastpbkdf2 pycrypto
