kdmp-parser

Esta biblioteca C++ analisa dumps completos do kernel do Windows full (.dump /f no WinDbg), dumps BMP (.dump /ka no WinDbg), bem como tipos de dump mais recentes introduzidos por volta de 2022.

parser

A biblioteca suporta carregar dumps de 64 bits e fornece acesso de leitura a coisas como:

O registro de contexto,
O registro de exceção,
Os parâmetros de bugcheck,
A memória física.

Binários compilados estão disponíveis na seção releases.

Agradecimentos especiais a:

hugsy por inúmeras contribuições: os novos bindings para Python, melhorias de CI, novos tipos de dump, etc.,
masthoon pela versão inicial dos bindings para Python,
yrp604 por conhecer bem o formato,
ao projeto rekall e à sua implementação em Python (a maioria das estruturas em kdmp-parser-structs.h foi adaptada dele).

Parser

O aplicativo parser.exe é capaz de despejar várias informações sobre o arquivo de dump: registro de exceção, registro de contexto, etc.

>parser.exe -c -e -p 0x1000 full.dmp

Compilação

Você mesmo pode compilá-la usando CMake, e ela compila em Linux, Windows e OSX com os compiladores Microsoft, LLVM Clang e GNU.

Aqui está um exemplo no Windows:

> mkdir build
> cd build
> cmake ..
-- Building for: Visual Studio 17 2022
...

> cmake --build . --config RelWithDebInfo
MSBuild version 17.8.3+195e7f5a3 for .NET Framework
...

> src\parser\RelWithDebInfo\parser.exe
You didn't provide the path to the dump file.

parser.exe [-p [<physical address>]] [-c] [-e] [-h] <kdump path>

Examples:
  Show every structures of the dump:
    parser.exe -a full.dmp

  Show the context record:
    parser.exe -c full.dmp

  Show the exception record:
    parser.exe -e full.dmp

  Show all the physical memory (first 16 bytes of every pages):
    parser.exe -p full.dmp

  Show the context record as well as the page at physical address 0x1000:
    parser.exe -c -p 0x1000 full.dmp

Aqui está outro exemplo no Linux (com os bindings para Python):

$ mkdir build
$ cd build
$ cmake .. -DBUILD_PYTHON_BINDING=ON
...

$ cmake --build . --config RelWithDebInfo
...

$ ./src/parser/parser
You didn't provide the path to the dump file.

parser.exe [-p [<physical address>]] [-c] [-e] [-h] <kdump path>

Examples:
  Show every structures of the dump:
    parser.exe -a full.dmp

  Show the context record:
    parser.exe -c full.dmp

  Show the exception record:
    parser.exe -e full.dmp

  Show all the physical memory (first 16 bytes of every pages):
    parser.exe -p full.dmp

  Show the context record as well as the page at physical address 0x1000:
    parser.exe -c -p 0x1000 full.dmp

Bindings para Python

Via PyPI

A maneira mais fácil é simplesmente:

pip install kdmp_parser

Usando PIP

Execute o seguinte após instalar o CMake e o Python 3.8+ / pip:

cd src/python
pip install requirements.txt
pip install .

Para criar um pacote wheel:

cd src/python
pip wheel .

Uso

Obter o contexto e imprimir o contador de programa

import kdmp_parser
dmp = kdmp_parser.KernelDumpParser("full.dmp")
assert dmp.type == kdmp_parser.DumpType.FullDump
print(f"Dump RIP={dmp.context.Rip:#x}")

Ler uma página de memória virtual no endereço apontado por RIP

import kdmp_parser
dmp = kdmp_parser.KernelDumpParser("full.dmp")
dmp.read_virtual_page(dmp.context.Rip)

Explorar a memória física

import kdmp_parser
dmp = kdmp_parser.KernelDumpParser("full.dmp")
pml4 = dmp.directory_table_base
print(f"{pml4=:#x}")
dmp.read_physical_page(pml4)

Traduzir um endereço virtual em um endereço físico

import kdmp_parser
dmp = kdmp_parser.KernelDumpParser("full.dmp")
VA = dmp.context.Rip
PA = dmp.translate_virtual(VA)
print(f"{VA=:#x} -> {PA=:#x}")
