这是 Windows 通知设施（WNF）工具的仓库。 目前，已上传了 Alex Ionescu（@aionescu）和 Gabrielle Viala（@pwissenlit）所开发的 wnfun 中工具的 C# 移植版本。 当我为 Windows 通知设施开发更多工具时，它们将被上传到这里。
此工具用于转储或操作有关 WNF 状态名称的信息。 等同于 wnfdump.exe 和 WnfDump.py。 我对原始工具进行了一些更新（异常处理、已知状态名称和新的 WNF_DATA_SCOPE 成员）。
要检索主机上所有已知、永久和持久 WNF 状态名称的信息，请使用 -d（--dump）标志执行：```
PS C:\Dev> .\SharpWnfDump.exe -d
| WNF_WEBA_CTAP_DEVICE_STATE | S | W | N | RW | I | 0 | 12 | 0 | | WNF_WEBA_CTAP_DEVICE_CHANGE_NOTIFY | S | W | N | RW | I | 0 | 4 | 0 | | WNF_PNPA_DEVNODES_CHANGED | S | W | N | RO | U | 0 | 0 | 11 |
--snip--
仅显示系统中使用的状态名称，请设置 `-u`（`--used`）标志。
此标志可应用于 `-d` 和 `-b` 选项：```
PS C:\Dev> .\SharpWnfDump.exe -d -u
| WNF State Name [WellKnown Lifetime] | S | L | P | AC | N | CurSize | MaxSize | Changes |
----------------------------------------------------------------------------------------------------------------------
| WNF_PNPA_DEVNODES_CHANGED | S | W | N | RO | U | 0 | 0 | 140 |

| WNF_AUDC_CAPTURE | S | W | N | RO | U | 4096 | 4096 | 1 |
| WNF_AUDC_SPATIAL_STATUS | S | W | N | RO | U | 4096 | 4096 | 3 |
--snip--
如果要检索安全描述符信息，请设置 -s (--sid) 标志：```
PS C:\Dev> .\SharpWnfDump.exe -d -s
| WNF_WEBA_CTAP_DEVICE_STATE | S | W | N | RW | I | 0 | 12 | 0 |

--snip--
如果你想检索缓冲区数据，请设置 `-v`（`--value`）或 `-r`（`--read`）标志。
这些标志可以与 `-s` 标志一起使用：```
PS C:\Dev> .\SharpWnfDump.exe -d -v
| WNF State Name [WellKnown Lifetime] | S | L | P | AC | N | CurSize | MaxSize | Changes |
----------------------------------------------------------------------------------------------------------------------

--snip--
要检索主机上所有临时 WNF 状态名称的信息，请使用 -b（--brut）标志执行：```
PS C:\Dev> .\SharpWnfDump.exe -b
| 0x41C64E6DA3AC3845 | S | T | N | RW | A | 8 | ? | 1 | | 0x41C64E6DA3AC4845 | S | T | N | RW | A | 8 | ? | 1 | | 0x41C64E6DA3AC6845 | S | T | N | RW | A | 8 | ? | 1 |
--snip--
`-b`（`--brut`）标志可以与 `-v`（`--value`）或 `-r`（`--read`）标志一起使用，但不能与 `-s`（`--sid`）标志一起使用。
从 `--dump` 或 `--brut` 选项结果中获得的表格中各列的含义如下：
| 列名 | 描述 |
| :--- | :--- |
| `WNF State Name` | 此处输出 WNF State Name |
| `S` | WNF State Name 的数据范围。显示的字母含义如下：<br><br>+ `S` : 系统范围<br>+ `s` : 会话范围<br>+ `U` : 用户范围<br>+ `P` : 进程范围<br>+ `M` : 计算机范围<br>+ `p` : 物理机范围 |
| `L` | WNF State Name 的生命周期。显示的字母含义如下：<br><br>+ `W` : 已知<br>+ `P` : 永久<br>+ `V` : 持久（易失）<br>+ `T` : 临时 |
| `P` | 显示 WNF State Name 是否永久：<br><br>+ `Y` : 是<br>+ `N` : 否 |
| `AC` | WNF State Name 的访问控制：<br><br>+ `RW` : 可读写<br>+ `RO` : 只读<br>+ `WO` : 只写<br>+ `NA` : 不可读写 |
| `N` | 显示订阅者是否存在：<br><br>+ `A` : 存在订阅者<br>+ `I` : 不存在订阅者<br>+ `U` : 未知 |
| `CurSize` | 该数字表示 WNF State Name 当前使用的缓冲区大小。 |
| `MaxSize` | 该数字表示 WNF State Name 可使用的最大缓冲区大小。 |
| `Changes` | 该数字表示更新次数。 |
如果要检索特定 WNF State Name 的信息，请使用 `-i`（`--info`）选项执行 `SharpWnfDump.exe`，如下所示：```
PS C:\Dev> .\SharpWnfDump.exe -i WNF_SHEL_APPRESOLVER_SCAN

----------------------------------------------------------------------------------------------------------------------

-i（--info）选项可以与 -v（--value）、-r（--read）和 -s（--sid）标志一起使用：```
PS C:\Dev> .\SharpWnfDump.exe -i WNF_SHEL_APPRESOLVER_SCAN -s -v

要向特定的 WNF 状态名称写入数据，请使用 -w (--write) 标志，如下所示（用于写入的数据应通过文件提供）：```
PS C:\Dev> "hi" | Out-File -Encoding ascii -FilePath C:\Dev\test.txt

### SharpWnfNameDumper
[返回顶部](#sharpwnfsuite)
[项目](https://github.com/daem0nc0re/sharpwnfsuite/blob/main/SharpWnfSuite/SharpWnfNameDumper)
该工具从 DLL（通常是 perf_nt_c.dll）中转储已知状态名称（Well-Known State Name）。
等同于 [WnfNameDumper.py](https://github.com/ionescu007/wnfun/blob/master/script_python/WnfNameDumper.py)。
通常，已知状态名称（Well-Known State Names）包含在 perf_nt_c.dll 中（该 DLL 位于 Windows Performance Analyzer 中）。
要从 DLL 中转储已知状态名称（Well-Known State Names），请按如下方式使用 `-d`（`--dump`）选项执行 `SharpWnfNameDumper.exe`：```
PS C:\Dev> .\SharpWnfNameDumper.exe -d perf_nt_c.dll
[>] Output results in C# style.
public enum WELL_KNOWN_WNF_NAME : ulong
{
WNF_9P_REDIRECTOR_STARTED = 0x41C61E54A3BC1075UL,
WNF_9P_UNKNOWN_DISTRO_NAME = 0x41C61E54A3BC0875UL,
--snip--
如果你想要转储知名状态名称（Well-Known State Names）的描述，请设置 -v 标志：```
PS C:\Dev> .\SharpWnfNameDumper.exe -d perf_nt_c.dll -v
[>] Output results in C# style.
public enum WELL_KNOWN_WNF_NAME : ulong { // The Plan 9 Redirector was started and is ready to accept requests. WNF_9P_REDIRECTOR_STARTED = 0x41C61E54A3BC1075UL, // The Plan 9 Redirector got a request for an unknown WSL distribution and there is no user callback registered to query it. WNF_9P_UNKNOWN_DISTRO_NAME = 0x41C61E54A3BC0875UL,
--snip--
要指定输出格式，请使用 `-f`（`--format`）选项。`SharpWnfNameDumper.exe` 支持 C#、C（`-f c`）和 Python（`-f py`）格式（默认格式为 C#）：```
PS C:\Dev> .\SharpWnfNameDumper.exe -d perf_nt_c.dll -f py
[>] Output results in Python style.
g_WellKnownWnfNames = {
"WNF_9P_REDIRECTOR_STARTED": 0x41C61E54A3BC1075,
"WNF_9P_UNKNOWN_DISTRO_NAME": 0x41C61E54A3BC0875,
--snip--
要将结果输出到文件，请使用 -o（--output）选项指定输出文件路径：```
PS C:\Dev> .\SharpWnfNameDumper.exe -d perf_nt_c.dll -o result.txt
[>] Output results in C# style.
C:\dev>type result.txt public enum WELL_KNOWN_WNF_NAME : ulong { WNF_9P_REDIRECTOR_STARTED = 0x41C61E54A3BC1075UL, WNF_9P_UNKNOWN_DISTRO_NAME = 0x41C61E54A3BC0875UL,
--snip--
要对两个 DLL 进行差异比较，请使用 `-D` (`--diff`) 选项：```
PS C:\Dev> .\SharpWnfNameDumper.exe -D perf_nt_c_old.dll perf_nt_c_new.dll
[>] Output results in C# style.

WNF_SHEL_MAC_AUTO_UPDATE_SUCCEEDED = 0x0D83063EA3B89875UL
}
这是一个用于订阅 WNF 状态名称的工具。 相当于 wnfclient-rtl.exe 和 WnfClientServer.py。
例如，如果你想监控 WNF_SHEL_APPLICATION_STARTED 的状态，请按如下方式执行 SharpWnfClient.exe：```
PS C:\Dev> .\SharpWnfClient.exe WNF_SHEL_APPLICATION_STARTED

此工具创建一个临时生命周期的 WNF 状态名称，并向订阅者发送一些消息。 相当于 wnfserver.exe 和 WnfClientServer.py。
要启动新的 WNF 状态名称服务器，只需执行 SharpWnfServer.exe。我们将进入如下所示的交互式 shell：```
PS C:\Dev> .\SharpWnfServer.exe

执行 `SharpWnfServer.exe` 后，在另一个终端中执行 `SharpWnfClient.exe`，并提供 `SharpWnfServer.exe` 显示的 WNF State Name。你应该会收到来自 `SharpWnfServer.exe` 的消息 "Hello, world!"：```

此工具用于研究攻击者如何滥用 WNF 进行代码注入技术：``` PS C:\Dev> .\SharpWnfInject.exe -h
SharpWnfInject - Tool to investigate WNF code injection technique.
Usage: SharpWnfInject.exe [Options]
-h, --help : Displays this help message.
-n, --name : Specifies WNF State Name to inject. Hex format or Well-known name format is accepted.
-p, --pid : Specifies PID to inject.
-i, --input : Specifies the file path to shellcode.
-d, --debug : Flag to enable SeDebugPrivilege. Requires administrative privilege.
[!] -n option is required.
该工具会覆盖特定 WNF 状态名称的 `WNF_USER_SUBSCRIPTION` 中的回调函数指针。
此代码注入技术并非适用于所有 WNF 状态名称。
例如，已知该技术可用于 Windows 11 23H2 中由 `explorer.exe` 使用的 `WNF_SHEL_WINDOWSTIP_CONTENT_PUBLISHED`。
要测试此技术，请按如下方式执行此工具：```
PS C:\Dev> .\SharpWnfInject.exe -p 5800 -n WNF_SHEL_WINDOWSTIP_CONTENT_PUBLISHED -i .\notepad_arm64.bin
[*] Target WNF State Name is 0x0D83063EA3BE10F5 (WNF_SHEL_WINDOWSTIP_CONTENT_PUBLISHED).

如果要启用 SeDebugPrivilege，请设置 -d 标志并以管理员权限执行。
用于执行记事本的示例 shellcode 位于 Shellcode 目录。
此目录中的项目用于演示内核利用的 WNF 原语。 你可以阅读 Alex Plaskett 的演讲和博客中的详细信息（第 1 部分、第 2 部分、幻灯片）。
该 PoC 的可靠性并非 100%。 我为所有 Windows 10 x64 版本定义了内核偏移量，但仅在 Windows 10 Version 1903 x64 上进行了测试。
| Project | Description |
|---|---|
| PoolVulnDrv | 这是一个存在漏洞的内核驱动程序，用于测试 WNF 内核原语。 |
| WnfPoolOverflow | 这是一个利用 PoolVulnDrv 的 PoC。 |
此目录包含用于构建你自己的 WNF 回调 shellcode 的文档和示例代码。 请参阅 README.md。
