Forensic Research & Engineering Notes
Rigorous, reproducible technical inquiries into file system internals, digital evidence preservation, and data recovery engineering.
Publications in Development
Our research papers, technical notes, and methodology write-ups are being prepared alongside our core software development. In accordance with our engineering principles, we publish research only when findings are thoroughly tested, reproducible, and peer-reviewable.
We do not publish placeholder articles, speculative whitepapers, or marketing copy disguised as technical research.
Core Technical Focus Areas
The questions and methodologies currently guiding our investigative work and software architecture.
File System Structure & Cluster Carving
Investigating algorithms for reconstructing fragmented file sequences across damaged partition tables, corrupted master file tables, and non-contiguous cluster allocations.
- Fragmented sector reassembly
- Corrupted metadata parsing
- Deterministic header/footer verification
Solid-State Storage & Write-Blocking Validation
Analyzing media controller behaviors, wear-leveling artifacts, and background garbage collection in modern flash storage to ensure authentic non-destructive examination.
- Controller background operations
- Forensically safe access primitives
- Cryptographic checksum consistency
Digital Artifact Timeline Reconstruction
Developing structured methods to normalize and correlate temporal timestamps across diverse operating system artifacts, file systems, and log structures.
- Timestamp precision and resolution
- Cross-artifact event correlation
- Anti-tampering verification heuristics
Forensic Tool Validation & Reproducibility
Establishing rigorous testing methodologies to benchmark data extraction algorithms against standardized digital forensic reference images.
- Reference image benchmarking
- Algorithmic false-positive auditing
- Defensible forensic error bounds
Principles of 404Evidence Research
Reproducibility
Every methodology is documented with precise steps, algorithmic definitions, and verifiable conditions.
Forensic Defensibility
Techniques are validated against rigorous standards where evidence integrity cannot be compromised.
Transparent Boundaries
We explicitly report heuristic limits, failure modes, and areas requiring ongoing empirical study.
