OSINT Guides.
One topic worked start to finish, from first source to finished file.
GitHub OSINT: finding exposed secrets and infrastructure.
Search code, commit history and contributor metadata to recover leaked credentials and map infrastructure tied to a repository.
Shodan OSINT: finding exposed infrastructure behind a domain.
Query Shodan's pre-built index to surface exposed services tied to a domain's IP range, without touching the target directly.
Sherlock OSINT: username pivoting beyond WhatsMyName.
Sherlock's separately maintained list of over four hundred sites is the natural second opinion to WhatsMyName, surfacing accounts each tool misses on its own.
Email account enumeration: tools beyond Holehe check.
Maigret, Blackbird and GHunt extend account discovery past Holehe's password-reset check, widening platform coverage for a single email address.
OSINT Reference Card Library.
Field-ready tradecraft. Live next to a keyboard, not in a slide deck.
DRK-002
Tor network fundamentals for dark web investigators.
Access .onion services, document sessions to chain-of-custody standard and identify deanonymisation vectors.
LGL-002
Civil and criminal judgment research for investigators.
Extract judicial findings, asset disclosures and named associates from court dockets across an eight-step PACER workflow.
SPC-002
Identifying satellite operators and owners.
Cross-reference ITU frequency filings, Space-Track TLE data and corporate registries to name the licensed operator and beneficial owner behind a satellite.
IDN-002
Cross-platform username tracing to identity attribution.
Enumerate handles across hundreds of platforms with Sherlock, cross-reference breach data and build a convergence dossier to evidentiary standard.
AI in OSINT.
Integrating AI tools and language models into your OSINT workflow.
Phone number carrier mismatch: AI hypothesis analysis.
When the subscriber name does not match, a structured AI prompt ranks the explanations and identifies the discriminating next query.
Writing style analysis across three anonymous forums.
A structured AI prompt scores stylometric convergence across forum handles and flags divergence, with indeterminate as the honest verdict when the signal will not support one.
The email address appears in four breach sets under different names.
A structured prompt that surfaces the consistency signals across a decade of breaches and ranks the attribution candidates by persistence score.
Two companies, one director name, three jurisdictions.
A prompt that normalises registry extracts onto one schema and surfaces the fields doing the discriminating work across OpenCorporates, ICIJ and OCCRP Aleph.
OSINT Methodology Tutorials.
Step-by-step tutorials drawn from working casework.
Dark web access: legal and ethical boundaries for investigators.
Apply CMA, CFAA and GDPR Article 6 to dark web access, build a Tails OS environment, and capture evidence to evidentiary standard.
Mobile location intelligence: advertising IDs and BSSID.
How advertising identifiers and Wi-Fi probe records expose device movement, and the legal constraints that govern their use in investigations.
Financial flows and sanctions evasion: investigator's guide.
Screen entities across sanctions regimes, map beneficial ownership through corporate registries and document the ownership chain to evidentiary standard.
Satellite imagery change detection: Sentinel and Landsat.
Use ESA and USGS multispectral archives to document ground-truth change over time, with a reproducible evidence chain.
The Signal.
A weekly practitioner briefing built around one open-source methodology. Each issue takes a live event as proof the technique matters, then builds the evidentiary file around it.
The Signal, Issue #007.
Federal agencies confirmed PLC intrusions at water utilities in seven US states, with the Iran attribution unconfirmed. Shodan and Censys map the same exposure the attackers exploited, and the record holds a technical pattern and no forensic proof.
The Signal, Issue #006.
Human Rights Watch put five flaring sites on the open record this week. Perenco says 220 flare points are permanently out. Neither claim resolves without a date, and that gap is the story.
The Signal, Issue #005.
ICE would not name the agent who killed Johan Sebastian Duran Guerrero in Biddeford. Six public records, from employment history to a court filing, corroborated his identity in three days, and the same denial has now repeated across three shootings in two weeks.
The Signal, Issue #004.
A 2022 chat leak and two federal court judgments show how Patriot Front actually funds itself. The march was staged for cameras, the ledger was not.
