1. 注意事项

“Napper”是一款用于检查离散TPM和固件TPM（Intel PTT）的新型漏洞检测工具。CVE-2018-6622及一个未知CVE与高级配置与电源接口（ACPI）的S3休眠状态或挂起相关。攻击者可利用S3休眠破坏TPM，并使得基于平台配置寄存器（PCR）的远程认证及密封/解封功能失效。如需了解CVE-2018-6622及未知CVE的详细信息，请阅读我们的USENIX论文《A Bad Dream: Subverting Trusted Platform Module While You Are Sleeping》以及Black Hat Europe 2019演讲《BitLeaker: Subverting BitLocker with One Vulnerability》。

Napper采用GPL v2许可协议。

2. Napper简介

可信平台模块（TPM）是一种防篡改设备，旨在提供基于硬件或固件的安全功能。TPM芯片包含随机数生成器、非易失性存储、加密/解密模块以及平台配置寄存器（PCR），可用于BitLocker、DM-Crypt、可信启动（tboot）和开放云完整性技术（Open CIT）等多种安全应用。

TPM已广泛部署在商用设备中，为构建可信平台提供了坚实基础，尤其是在企业及政府系统中。由于TPM是可信平台的关键节点，许多研究人员曾试图发现TPM中的漏洞，并得出结论：没有物理访问权限很难攻破它。然而，这一结论已不再成立。

我们发现的漏洞可通过高级配置与电源接口（ACPI）破坏TPM。PC、笔记本电脑和服务器中的ACPI提供了六种休眠状态（S0-S5）以降低功耗。当系统进入休眠状态时，CPU、设备和RAM将断电。由于系统会关闭包括安全设备在内的组件，因此在唤醒时需要重新初始化它们，这便成为了攻击面。我们无需物理访问即发现了该攻击面上的漏洞。

为缓解这些漏洞，我们还提出了应对措施并使用新工具“Napper”来检查TPM的漏洞。Napper是一个基于Linux的可启动USB设备，包含内核模块和漏洞检查软件。当您使用Napper启动系统时，它会让系统“小睡”以检查漏洞，并向您报告结果。

3. 如何使用“Napper”工具

Napper包含一个特殊的内核模块和定制的tpm2工具。Napper基于Ubuntu 18.04，我们对其进行了定制和裁剪以制作Live CD镜像。如果您只想检查TPM漏洞并希望采用简单的方式，请跳至第3.1节，使用Napper Live CD镜像与您的USB存储设备。Napper Live CD不仅包含二进制工具，还包含Napper的完整源代码。如果您当前使用Ubuntu 18.04并希望从头构建Napper，请跳至第3.2节进行构建。

3.1. 使用您自己的USB存储设备与Napper Live CD镜像（简版）

3.1.1. 从Napper项目获取Napper Live CD镜像

Napper Live CD镜像存放于Napper项目的发布页面。

3.1.2. 将Napper Live CD镜像写入您的USB存储设备

如果您使用Microsoft Windows操作系统，请使用Win32 Disk Imager并将Napper Live CD镜像写入您的USB存储设备。

如果您使用Linux或Mac OS X，请使用以下dd命令。```

Please change sdX to your USB storage name.

$> sudo dd if=Napper-LiveCD.iso of=/dev/sdX bs=4096 $> sync

### 3.1.3. 使用USB存储重启系统并运行Napper
插入USB存储并更改引导顺序以使用它启动后，您将看到Napper的引导菜单，选择第一个选项即可启动Napper Live CD。

启动完成后，您会在桌面上看到README.txt文件，左侧任务栏上有Napper工具图标。要检查您的系统，请点击任务栏顶部的图标，并输入密码`napper`。Napper工具的`ID`和`密码`均设置为`napper`。在Napper测试系统时，它会使系统进入休眠并唤醒。因此，您需要敲击键盘将系统从ACPI S3休眠状态唤醒。

如果您的系统存在TPM漏洞，Napper将在此处报告摘要，表明您的系统易受攻击。如果是这样，请跳转到第4节，并将摘要通过[Napper项目的Issue报告](https://github.com/kkamagui/napper-for-tpm/issues)或[网站](https://kkamagui.github.io/)分享给我们的项目Napper。

## 3.2. 从零开始使用Ubuntu 18.04构建Napper（详细版本）
### 3.2.1. 下载Ubuntu 18.04并克隆Napper源代码
Napper基于Ubuntu 18.04。因此，您需要从[Ubuntu官方网站](https://www.ubuntu.com/download/desktop)下载并安装到目标系统上。然后，从[Napper项目站点，https://www.github.com/kkamagui/napper-for-tpm](https://www.github.com/kkamagui/napper-for-tpm)克隆Napper源代码，并使用以下命令构建。```
# Clone Napper source code from project site.
$> git clone https://github.com/kkamagui/napper-for-tpm.git

# Build Napper.
$> cd napper-for-tpm
$> ./bootstrap

3.2.2. 使用终端运行Napper

构建源代码后，您可以使用终端运行Napper工具。请在终端中输入以下命令。Napper前端由Python脚本构成。```

Run Napper

$> sudo ./napper.py ,----------------, ,---------, ,-----------------------, ," ,"| ," Napper v 1.3 for TPM ,"| ," ," | +-----------------------+ | ," ," | | .-----------------Z | | +---------+ | | | Z | | | | -==----'| | | | ︶︶ z | | | | | | | | - | | |/----| ==== oo | | | | | | | ,/| (((( | ," | -----------------' |," .;'/ | (((( | ," +-----------------------+ ;; | | |," /_)______________(_/ //' | +---------+ ___________________________/___ , / oooooooooooooooo .o. oooo / ,"--------- / ==ooooooooooooooo==.o. ooo= / ,\--{-D) ," -----------------------------' '----------"

6. 测试结果

我们将根据您的贡献更新此字段。我们正在测试我们拥有的几台设备，并将很快更新结果。

7. 已知问题

部分机器在 S3 休眠期间会关闭 USB 存储设备的电源，并且无法重新连接。在这种情况下，请将 USB 存储设备插入系统的“始终供电”端口。
Ubuntu 18.04 有时无法在系统中找到 TPM。在这种情况下，请重新启动 Napper 并重试。
如果启用了安全启动，系统将无法使用 Napper 启动。测试时，请临时禁用安全启动选项。

8. 待办事项

微软设备，如 Surface Book 2、Surface Pro 6、Surface Laptop 2，尚不受 Ubuntu 18.04 和 Kernel 4.18.0-15 支持。升级内核后需要进行测试。
