-> If you came here for `MmNonPagedPoolStart`, `MmNonPagedPoolEnd`, you ended up at the right place.
+# LPUS (A live pool-tag scanning solution)

-`NonPagedPool` in Windows has two variables that defined the start and end of the section in kernel memory. Online blog posts and tutorials show an outdated version of these two variables.
+This is the frontend to the live pool tag scanning solution, the backend is a driver (which is now closed source).

-Take a look at [this old post](https://web.archive.org/web/20061110120809/http://www.rootkit.com/newsread.php?newsid=153). `_DBGKD_GET_VERSION64 KdVersionBlock` was a very important structure into the debugger block of Windows. However, if you try to find this structure in Windows 10, you will hit `KdVersionBlock == 0` (Ouch!!!). But this structure provides offset into `MmNonPagedPool{Start,End}`, how can we get those?
+## How this works

-Luckily, both `MmNonPagedPoolStart` and `MmNonPagedPoolEnd` in Windows XP, can be found by offseting from `ntoskrnl.exe`. Rekall team are very positive that their tools doesn't rely on profiles file like Volatility but use PDB provided by Windows to find these values.
+In simple way, we use PDB files to get the global variable offsets and structure definitions.
+The backend finds the kernel base and use these values to calculate the nonpaged-pool range.
+A more detailed report is in [nonpaged-pool-range.md](nonpaged-pool-range.md)
+The frontend calls the backend to scan for a specific tag.

-In [Rekall source code](https://github.com/google/rekall/blob/c5d68e31705f4b5bd2581c1d951b7f6983f7089c/rekall-core/rekall/plugins/windows/pool.py#L87), the values of those variables are:
+## How to use

- Windows XP: `MmNonPagedPool{Start,End}`
- Windows 7 and maybe 8: `MiNonPagedPoolStartAligned`, `MiNonPagedPoolEnd`, and `MiNonPagedPoolBitMap`
- Windows 10 below
+Example is [here](./src/bin/eprocess_scan.rs).

-In Windows 7, 8, another field was added to controll the allocation of `NonPagedPool`, which is why there is [this paper about pool tag quick scanning](https://www.sciencedirect.com/science/article/pii/S1742287616000062).
-
-However, from Windows 10, the whole game change around when the global offset to those (similar) variables. Instead Windows 10 introduced a new structure `MiState`. `MiState` offset is available and we can get the variables by either:
-
- Windows 2015: `*((ntoskrnl.exe+MiState)->SystemNodeInformation->NonPagedPool{First,Last}Va)`
- Windows 2016: `*((ntoskrnl.exe+MiState)->Hardware.SystemNodeInformation->NonPagedPool{First,Last}Va)`
-
-The `NonPagedBitMap` was still visible untill the May 2019 Update, here, take a look at these 2 consecutive update [`1809 Redstone 5 (October Update)`](https://www.vergiliusproject.com/kernels/x64/Windows%2010%20%7C%202016/1809%20Redstone%205%20(October%20Update)/\_MI\_SYSTEM\_NODE\_INFORMATION) and [`1903 19H1 (May 2019 Update)`](https://www.vergiliusproject.com/kernels/x64/Windows%2010%20%7C%202016/1903%2019H1%20(May%202019%20Update)/\_MI\_SYSTEM\_NODE\_INFORMATION).

-Yeah, now `pool tag quick scanning` is useless (gah). Windows OS changes quite frequently right? Tell you more, I am using the Insider version of Windows in 2020, and guess what, I found out that they put another struct to point to those value. So now we need to go like this:
-
- Windows 2020 Insider preview: `*((ntoskrnl.exe+MiState)->SystemNodeNonPagedPool->NonPagedPool{First,Last}Va)`
-
-Anyway, I create this project to help me with my thesis, following outdated structs online yields no result. Oh, yeah, a guy seems to be asking on [how to get `MmNonPagedPoolStart`](https://reverseengineering.stackexchange.com/q/6483) on `stackexchange`, too bad [the answer](https://reverseengineering.stackexchange.com/a/6487) is not so much helpful.

-Take a look at my ntoskrnl.exe pdb file parsed.
+```rust
+use lpus::{
+    driver_state::{DriverState}
+};

+fn main() -> Result<(), Box<dyn Error>> {
+    let mut driver = DriverState::new();
+    println!("NtLoadDriver()   -> 0x{:x}", driver.startup());
+    driver.scan_pool(b"Tag ", |pool_addr, header, data_addr| {
+    })?;
+    println!("NtUnloadDriver() -> 0x{:x}", driver.shutdown());
+}
 ```
-PDB for Amd64, guid: 3e7ee354-590f-ac1c-62a8-ccf0b6368989, age: 1,

-MiState 0xc4f280 23:324224
-KdDebuggerDataBlock 0xc00a30 23:2608
+The closure is a mutable closure, so you can just put a vector and saves the result.
+The function signature for the closure is: `FnMut(u64, &[u8], u64) -> Result<bool, std::error::Error>`
+Parsing the struct data is up to you.
+You can use `driver.deref_addr(addr, &value)` to dereference an address in kernel space
+and `driver.pdb_store.get_offset_r("offset")?` to get an offset from PDB file.

+> If you came here for `MmNonPagedPoolStart`, `MmNonPagedPoolEnd`, you ended up at the right place.
+
+`NonPagedPool` in Windows has two variables that defined the start and end of the section in kernel memory. Online blog posts and tutorials show an outdated version of these two variables.
+
+Take a look at [this old post](https://web.archive.org/web/20061110120809/http://www.rootkit.com/newsread.php?newsid=153). `_DBGKD_GET_VERSION64 KdVersionBlock` was a very important structure into the debugger block of Windows. However, if you try to find this structure in Windows 10, you will hit `KdVersionBlock == 0` (Ouch!!!). But this structure provides offset into `MmNonPagedPool{Start,End}`, how can we get those?
+
+Luckily, both `MmNonPagedPoolStart` and `MmNonPagedPoolEnd` in Windows XP, can be found by offseting from `ntoskrnl.exe`. Rekall team are very positive that their tools doesn't rely on profiles file like Volatility but use PDB provided by Windows to find these values.
+
+In [Rekall source code](https://github.com/google/rekall/blob/c5d68e31705f4b5bd2581c1d951b7f6983f7089c/rekall-core/rekall/plugins/windows/pool.py#L87), the values of those variables are:
+
+- Windows XP: `MmNonPagedPool{Start,End}`
+- Windows 7 and maybe 8: `MiNonPagedPoolStartAligned`, `MiNonPagedPoolEnd`, and `MiNonPagedPoolBitMap`
+
+In Windows 7, 8, another field was added to controll the allocation of `NonPagedPool`, which is also mentioned in [this paper about pool tag quick scanning](https://www.sciencedirect.com/science/article/pii/S1742287616000062).
+
+However, from Windows 10, the whole game changed around when the global offset to those (similar) variables are gone. Instead Windows 10 introduced a new variable `MiState`. `MiState` offset is available and we can get those start/end variables by either:
+
+- Windows 2015: `(_MI_SYSTEM_INFORMATION*)(MiState)->SystemNodeInformation.NonPagedPool{First,Last}Va`
+- Windows 2016: `(_MI_SYSTEM_INFORMATION*)(MiState)->Hardware.SystemNodeInformation.NonPagedPool{First,Last}Va`
+
+The `NonPagedBitMap` was still visible untill the May 2019 Update, here, take a look at these 2 consecutive update [`1809 Redstone 5 (October Update)`](https://www.vergiliusproject.com/kernels/x64/Windows%2010%20%7C%202016/1809%20Redstone%205%20(October%20Update)/\_MI\_SYSTEM\_NODE\_INFORMATION) and [`1903 19H1 (May 2019 Update)`](https://www.vergiliusproject.com/kernels/x64/Windows%2010%20%7C%202016/1903%2019H1%20(May%202019%20Update)/\_MI\_SYSTEM\_NODE\_INFORMATION).
+
+Windows OS changes quite frequently right? Tell you more, I am using the Insider version of Windows in 2020, and guess what, I found out that they put another struct to point to those value. So now we need to go like this:
+
+- Windows 2020 Insider preview: `*(_MI_SYSTEM_INFORMATION*)(MiState)->Hardware.SystemNodeNonPagedPool.NonPagedPool{First,Last}Va`
+
+> If you go with low-level, then you only care about the offset and formula to get those variables but knowing the structure is well benefit.
+
+Anyway, I create this project to help me with my thesis, following outdated structs online yields no result. Oh, yeah, a guy seems to be asking on [how to get `MmNonPagedPoolStart`](https://reverseengineering.stackexchange.com/q/6483) on `stackexchange`, too bad [the answer](https://reverseengineering.stackexchange.com/a/6487) is not so much helpful.
+
+----
+
+Global variables offset are parsed from the PDB file and can be queried by `nt!` in Windbg. In a kernel driver, we need to get the kernel base address (which is `nt!`). Kernel base address is the loaded address of `ntoskrnl.exe`. There is a shellcode to get the address [here](https://gist.github.com/Barakat/34e9924217ed81fd78c9c92d746ec9c6), using IDT table. But when I use the shellcode with the Windows Insider preview 2020, the address is wrong (it still a loaded PE though). Other ways to get the address are listed [here](https://m0uk4.gitbook.io/notebooks/mouka/windowsinternal/find-kernel-module-address-todo). And hereby I present another way to get the kernel base address.
+
+A device driver can get a pointer to an `_EPROCESS` through the use of `PEPROCESS IoGetCurrentProcess`. And as we know, `_EPROCESS` has pointer to other `_EPROCESS` as a circular doubly linked list. If we dump them all out, we can notice a few things:
+
+- The image name returned by calling `IoGetCurrentProcess` in `DriverEntry` is `System`
+- The `_EPROCESS` before `System` is somehow empty
+
+```cpp
+// in DriverEntry
+PVOID eprocess = (PVOID)IoGetCurrentProcess();
+
+// somewhere after offsets are setup
+DbgPrint("eprocess : 0x%p, [%15s]\n", eprocess, (char*)((ULONG64)eprocess + ImageBaseNameOffset));
+for (int i = 0; i < 100; i++) {
+  eprocess = (PVOID)(*(ULONG64*)((ULONG64)eprocess + ActiveProcessLinksOffset) - ActiveProcessLinksOffset);
+  DbgPrint("eprocess : 0x%p, [%15s]\n", eprocess, (char*)((ULONG64)eprocess + ImageBaseOffset));
+}
+
+// sample output
+eprocess : 0xFFFFF8037401F528, [               ]
+eprocess : 0xFFFF840F5A0D9080, [         System]
+eprocess : 0xFFFF840F5A28C040, [  Secure System]
+eprocess : 0xFFFF840F5A2EF040, [       Registry]
+eprocess : 0xFFFF840F622BF040, [       smss.exe]
+eprocess : 0xFFFF840F6187D080, [       smss.exe]
+eprocess : 0xFFFF840F6263D140, [      csrss.exe]
+eprocess : 0xFFFF840F6277F0C0, [       smss.exe]
+eprocess : 0xFFFF840F627C2080, [    wininit.exe]
+eprocess : 0xFFFF840F64187140, [      csrss.exe]
+eprocess : 0xFFFF840F641CD080, [   services.exe]
+```
+
+And if we debug and compare the address of that `Empty _EPROCESS+ActiveProcessLinksOffset` with `nt!PsActiveProcessHead`, it is just the same. And with the given offset parsed from the PDB file, we can get kernel base address.
+
+```cpp
+// In DriverEntry
+PVOID eprocess = (PVOID)IoGetCurrentProcess();
+
+// somwhere after offsets are setup
+DbgPrint("eprocess               : 0x%p, [%15s]\n", eprocess, (char*)((ULONG64)eprocess + ImageBaseNameOffset));
+PVOID processHead = (PVOID)(*(ULONG64*)((ULONG64)eprocess + ActiveProcessLinksOffset + BLinkOffset));
+DbgPrint("PsActiveProcessHead    : 0x%p\n", processHead);
+PVOID ntosbase = (PVOID)((ULONG64)processHead - ActiveHeadOffset);
+DbgPrint("ntoskrnl.exe           : 0x%p\n", ntosbase);
+```
+
+From now we have successfully get the kernel base address to index into other global variables.
