What We Solve

Turn black boxes into mapped systems you can reason about, secure, migrate, and support.

We map inherited software, vendor-controlled components, devices, and opaque dependencies that source code alone cannot explain.

Reverse engineering matters when documentation lies, vendors vanish, or trust has to come from evidence.

  • Unknown behavior that blocks development and debugging
  • Legacy systems with lost knowledge and no maintainers
  • Security uncertainty inside third-party binaries
  • Protocol opacity in undocumented formats and traffic
  • M&A and partner diligence where opaque software becomes a business risk
  • Firmware and embedded failure modes without visibility
  • Driver issues causing crashes and instability
  • Supply chain risk from opaque dependencies
  • Incident response that requires forensic-grade evidence
  • Migration blockers when an undocumented system still has to interoperate

Unknown systems are expensive systems.

What You Get

  • Behavior map of the target component and its boundaries
  • Root-cause clarity for crashes, hangs, and corrupt states
  • Protocol and format specs reconstructed from real data
  • Security findings with exploitability context and fixes
  • Actionable outputs including tooling, scripts, notes, and documentation
  • Decision guidance for modernization, interoperability, containment, or replacement

Methods and Tooling

Static Analysis

  • Disassembly, decompilation, control flow and data flow mapping
  • Signature and pattern extraction, cross-reference analysis
  • Deobfuscation and packer handling when needed
  • Reconstructing structures, vtables, layouts, invariants, and interface boundaries

Dynamic Analysis

  • Debugging, tracing, instrumentation, and behavioral capture
  • API monitoring, syscall tracing, memory tracking
  • Sandboxing and controlled execution environments
  • Crash reproduction and deterministic triage

Protocols and Forensics

  • Traffic capture, message inference, format reconstruction
  • State machine extraction and edge-case mapping
  • Crypto and encoding analysis when relevant
  • Evidence-grade reporting for incidents, audits, and partner-side review

Vulnerability Research

  • Attack surface mapping and threat modeling
  • Fuzzing plans and harness development
  • Exploitability analysis and mitigation design
  • Patch validation and regression checks

Why Teams Move Fast

Senior engineers. Clear next steps. Work built for systems that carry real pressure.

Personal data is handled with clear discipline across GDPR, UK GDPR, CCPA/CPRA, PIPEDA, and DPA/SCC expectations where applicable.

Senior Access

Speak with engineers who can inspect, decide, and execute.

Usable First Step

Reviews, priorities, scope, and next moves your team can use right away.

Built for Pressure

AI, systems, security, native software, and low-latency infrastructure.

Delivery Senior-led Direct technical communication
Coverage AI, systems, security One team across the stack
Markets Europe, US, Singapore Clients across key engineering hubs
Personal data Privacy-disciplined GDPR, UK GDPR, CCPA/CPRA, PIPEDA, DPA/SCC-aware

Start with the system, the pressure, and the decision ahead. We shape the next move from there.
