Digital Forensics, Done Rigorously

Every artifact.
Every byte. Verified.

Lex Fortis Ventures covers mobile extraction, disk forensics, OSINT, CDR/IPDR analysis, and memory forensics with technically accurate, defensible methodology — built for investigators, analysts, and legal professionals who need results that hold up under cross-examination.

Scene 01 — Evidence Intake

Every investigation begins with an unbroken seal.

A tamper-evident bag, a case ID, a chain-of-custody log — before a single byte is examined, the physical evidence has to be provably untouched.

Scene 03 — Data In Motion

Not all data lanes are equal, and one of them should only run one way.

PCIe, SATA, USB, memory channels — every bus on a motherboard carries a different kind of evidence at a different kind of risk.

Scene 04 — Volatile Memory

RAM forgets in seconds. Capture it first, or lose it forever.

Encryption keys, running processes, chat fragments — everything volatile drains the instant power is lost. Order of volatility isn't academic.

Scene 05 — Disk & Platters

Deleted doesn't mean gone, on a platter. On flash, it means something else.

Sector by sector, a scan ring resolves what the file table forgot — and the same question gets a very different answer on an SSD.

Scene 06 — Mobile Extraction

The extraction tier you choose decides what you're allowed to find.

Logical, file-system, physical — each tier reaches deeper into the device, and only one of them reliably recovers what was deleted.

Scene 07 — Cell Tower & CDR

A tower doesn't give you a point. It gives you a sector, a bearing, and a story over time.

Sector handovers, azimuth cones, and a timeline of movement — cell records are probabilistic evidence, read correctly or not at all.

Scene 08 — IPDR & Network Flow

Behind a shared IP address, the port number is the only thing that's still yours.

Carrier-grade NAT hides thousands of subscribers behind one public IP — resolving a session back to a person means reading the port, not just the address.

Scene 09 — OSINT Graph

A username, an email, a domain — alone, coincidence. Together, a pattern.

Link analysis surfaces the relationships a single data point never could — the same reused photo, the same registrant email, the same wallet.

Scene 10 — Chain of Custody

Evidence that can't prove its own integrity is not evidence at all.

A cryptographic hash, sealed at acquisition and verified at every handoff, is what turns a hard drive into courtroom-ready proof.

Methodology

The Forensic Workflow

Every technique on this site maps back to this six-stage backbone — identification through presentation.

Identification

Recognize potential evidence sources and scope what needs to be seized.

Preservation

Isolate evidence from alteration — write blockers, Faraday bags, hashing.

Acquisition

Create a forensically sound, bit-for-bit copy of the original evidence.

Analysis

Examine the acquired copy to recover, correlate, and interpret artifacts.

Documentation

Record every action, tool, and finding with timestamps and hash values.

Presentation

Communicate findings clearly and defensibly to investigators or a court.

Last Known Location: Reconstructing a Missing Person's Final Hours via CDR

A 34-year-old man was reported missing after failing to return from a business trip. Cell tower handover analysis across two carriers narrowed the search area from a 40 km radius to a single 2 km corridor.

A pattern of near-identical 'investment opportunity' pitches across social media led investigators to a network of 14 fake profiles, three shell domains, and a single reused image asset that broke the case open.

Patient Zero: Reconstructing a Ransomware Incident From a Single Memory Capture

By the time IT called in forensic support, the ransomware note was already on screen and the encryption service had exited. A single RAM capture from the still-running server reconstructed the entire attack chain.

A departing employee's laptop showed nothing unusual. The proof was in the CGNAT-translated IPDR records showing a personal cloud-storage upload that lined up, second for second, with proxy logs from a device that was never issued to him.
