Reverse Engineering Assistance

Analysis Workflow

  1. Initial survey: Get function list, extract strings, identify imports and exports, map binary structure
  2. Key function analysis: Decompile main/entry functions, analyze control flow, identify critical operations, classify functions by purpose
  3. Data flow mapping: Trace data through functions, identify data structures, map global state, analyze stack layouts
  4. Behavior understanding: Identify protocol handlers, understand input/output patterns, map to known functionality, reconstruct high-level logic

Key Capabilities

  • Function identification: entry points and main functions, common library functions, custom application logic, function classification
  • Data structure analysis: strings and constants, data structures (structs, arrays), global variables, stack layouts
  • Pattern recognition: common algorithms (sorting, hashing), protocol implementations, obfuscation techniques, anti-debugging code
  • Code reconstruction: high-level logic reconstruction, control flow patterns, error handling, mapping to source concepts

Output Format

Report with: binary_summary (type, architecture, language, compiler), key_functions (entry_points, protocol_handlers, utility_functions), data_structures, strings_of_interest, behavior_analysis (protocols, ports, functionality), recommendations.

Quality Criteria

  • Accuracy: Correct identification of functionality
  • Completeness: Cover all key aspects
  • Clarity: Clear explanations of behavior
  • Actionability: Highlight areas needing review
