SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and validate unique byte signatures for instructions containing a specific struct member offset using IDA Pro MCP.

Core Features & Use Cases

  • Generate a signature for an instruction that embeds a struct offset, anchoring at the target instruction.
  • Enforce that the target instruction is fully fixed (no wildcards) and that the struct offset bytes are explicitly included.
  • Output the signature data, including VA, length, offset within the signature, and the struct offset value for verification.

Quick Start

Connect to IDA Pro MCP and run the signature-generation workflow for your target instruction to obtain the struct-offset signature.

FAQPage Schema
How do I generate a unique byte signature for an instruction with a struct offset in IDA Pro?▼

To generate a struct-offset signature, this Skill anchors at the target instruction in IDA Pro MCP, enforces fixed bytes, includes the displacement, and expands forward to ensure byte signature uniqueness.

What is a struct-offset signature used for in reverse engineering?▼

A struct-offset signature uniquely identifies an instruction containing a specific struct displacement, such as mov [rcx+1A8h], eax, enabling precise pattern matching and signature validation during reverse engineering analysis.

Can I use IDA Pro MCP to validate struct displacement signatures?▼

Yes, IDA Pro MCP is used to compute and validate struct-offset signatures, guaranteeing the target instruction is fully fixed without wildcards and that the struct displacement bytes are explicitly included in the output.

What metadata is included when generating an instruction signature?▼

Generating an instruction signature outputs the signature data, virtual address (VA), signature length, offset within the signature, and the struct offset value to provide complete verification metadata for the target instruction.

Why does my struct-offset signature include displacement bytes but no wildcards?▼

The signature generation enforces that the target instruction is fully fixed with no wildcards while explicitly including the struct displacement bytes to guarantee accurate signature validation and pattern matching.
