How to calculate the address of a function using the base address of ntoskrnl.exe

Asked 2022-Mar-29 at 18:59

This is what I have determined thus far on a test machine:

base address of ntoskrnl.exe is 0xFFFFF802C8803000
using IDA the address of the imagebase is 0x0000000140000000
using IDA the address of the function is 0x00000001401422D0
the offset (3 subtract 2) is determined to be 0x1422d0
the function address is determined to be 0xFFFFF802C8803000 + 0x1422d0 = 0xfffff802c89452d0
Windbg says the address is 0xfffff802c89454d0

Is the above calculations correct ? Please tell me what I'm doing wrong ?

Found the solution thanks to Neitsa. I was working with two different versions of ntoskrnl.exe one version for Windbg and the other version with IDA Free.

How to locate address of a function using base address of the executable?

Asked 2022-Mar-13 at 15:53

OK so I have the base address of ntoskrnl.exe and want to locate the address of an internal function that is neither exported or imported. How can this be done in kernel mode ?

...

ANSWER

Answered 2022-Mar-13 at 15:53

You can pattern scan for the function, or it has a static RVA. There are many ways, but the easiest is by creating a signature (for example with SigMaker in IDA Pro) and scanning for it inside your module.

For exported routines this is much easier:

https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/nf-wdm-mmgetsystemroutineaddress

For within a specific module, you can manually walk the EAT (Export Address Table).

Official documentation for ZwDeleteKey does mention "NtosKrnl.exe" being the "DLL", but this is wrong, the import definition should be like this instead (plus there's no string involved, the entry point is not ambiguous and the function doesn't set last error):

ANSWER

Answered 2021-Nov-18 at 06:39

Ok, I figured it out.

IoAllocateErrorLogEntry checks if the value of EntrySize is >= sizeof(IO_ERROR_LOG_PACKET) which is 48 bytes.

So my value of 44 bytes was simply too low.

QUESTION

Using Only FileSystemObject in a VBScript, How Can I Determine the Operating System's Processor Architecture?

Asked 2021-Feb-01 at 17:28

In VBScript on Windows RT, a running script only has access to three COM objects, one of which is Scripting.FileSystemObject.

How can I use only FileSystemObject to determine the operating system's processor architecture (in this case, it is ARM)?

Normally I would query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment -> PROCESSOR_ARCHITECTURE, or I would use WScript.Shell to get the system-level environment variable PROCESSOR_ARCHITECTURE. However, I cannot use the usual techniques in this situation.

Note: I thought about using Scripting.FileSystemObject to get the file version of ntoskrnl.exe, which would tell me that I'm on Windows version 6.3. And then after trying to create a WScript.Shell object and failing, making the assumption that I must be on an ARM Windows RT device. However, this feels very sloppy. It's been a while, but I have seen situations where antivirus interferes with the ability to instantiate objects in VBScript, and I want this code to be accurate/reliable.

ANSWER

Answered 2020-Sep-10 at 03:38

PsProcessType is exported at ntoskrnl.exe and is the same as ObRegisterCallbacks, the difference between them is that one is an exported global variable and the other is an exported function.

In C, these global variables are declared in wdm.h:

How to call ntoskrnl.exe srand function?

I have already tested with stdlib.h, but I would like to call ntoskrnl.exe directly.
