wshobson/padrões-de-análise-binária

Domine padrões de análise binária, incluindo desmontagem, descompilação, análise de fluxo de controle e reconhecimento de padrões de código. Use ao analisar executáveis, entender código compilado ou realizar análise estática em binários.

O que é padrões-de-análise-binária?

O skill 'wshobson/binary-analysis-patterns' foi projetado para capacitar agentes de IA, como Claude Code, Cursor e Codex, a realizar análise binária avançada. Ele abrange técnicas essenciais de engenharia reversa, incluindo desmontagem de código de máquina, descompilação para linguagens de alto nível, análise de fluxo de controle (CFG) e reconhecimento de padrões de código. É particularmente útil para desenvolvedores que trabalham com segurança de software, análise de malware, depuração de código compilado ou portabilidade de binários antigos. O skill opera com base em um guia estruturado (SKILL.md) que fornece instruções passo a passo e exemplos de comandos para ferramentas comuns como objdump, Ghidra, IDA Pro e radare2. Ao utilizar este skill, o agente pode orientar o usuário na extração de informações de executáveis, identificação de funções e bibliotecas, e compreensão da lógica do código compilado, tudo sem a necessidade de execução direta (análise estática).

O que padrões-de-análise-binária faz?

Domine padrões de análise binária, incluindo desmontagem, descompilação, análise de fluxo de controle e reconhecimento de padrões de código. Use ao analisar executáveis, entender código compilado ou realizar análise estática em binários.

Técnicas Principais

  • Desmontagem: Converter código de máquina em linguagem assembly legível usando ferramentas como objdump -d ou radare2 -A.
  • Descompilação: Transformar código de máquina em uma representação de alto nível (como C pseudo-código) usando Ghidra ou IDA Pro.
  • Análise de Fluxo de Controle (CFG): Mapear grafo de chamadas e blocos básicos para entender ramificações e laços.
  • Reconhecimento de Padrões: Identificar funções da biblioteca padrão (ex: strlen, memcpy) por sequências de bytes ou heurísticas.

Ferramentas Suportadas

FerramentaUso PrincipalComando Exemplo
objdumpDesmontagem básicaobjdump -d binary
GhidraDescompilação e análise avançadaghidraSwing (GUI) ou script headless
IDA ProEngenharia reversa interativaInterface gráfica ou linha de comando
radare2Análise de linha de comando e scriptingr2 -A binary

Exemplos de Uso

1. Desmontar um executável

objdump -d hello_world | head -50

2. Usar radare2 para análise de fluxo de controle

r2 -A binary
> afl  # Listar funções
> ag   # Gerar grafo de fluxo de controle

3. Reconhecimento de padrões com sequências de bytes

# Procurar por sequência de bytes para 'strlen'
strings -t x binary | grep "strlen"

Por que usar este skill?

  • Segurança: Analisar binários sem executá-los (análise estática).
  • Depuração: Entender código compilado quando o código fonte não está disponível.
  • Portabilidade: Migrar código binário para outras plataformas.
  • Educação: Aprender sobre compiladores e linguagem assembly.

Plataformas Compatíveis

  • Claude Code
  • Cursor
  • Codex
