What we do?

Turn black boxes into mapped systems you can reason about and control.

We reverse engineer binaries, firmware, protocols, and drivers to restore knowledge, fix failures, uncover vulnerabilities, and support safe modernization.

Reverse engineering is needed when documentation lies, vendors vanish, or a system must be trusted under pressure.

  • 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
  • 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

Clarity wins. 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, and documentation

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, and invariants

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 and audits

Vulnerability Research

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