Terminal-native passive OSINT CLI for local-first public-source investigation workspaces

REKOS

REKOS is a terminal-native passive OSINT CLI for local-first public-source investigation workspaces. It helps organize targets, evidence, source outputs, entities, relationships, normalized findings, and correlation-quality scores in a SQLite-backed case folder.

REKOS is designed for passive public-source workflows:

• Public-source investigation workspace
• Target and evidence organizer
• Username, profile, domain, URL, and indicator correlation tool
• Local-first OSINT case workspace
• No login automation, bypass, credential collection, or active exploitation

A case is a local workspace for one public-source research thread. Cases are stored under ~/rekos_cases/<case_name> by default. Each case keeps its own SQLite database, source outputs, evidence artifacts, graph records, findings, and exports.

Installation

REKOS requires Python >=3.10. Python 3.12 is recommended.

Windows PowerShell

Install:

py -m pip install --upgrade rekos

Run:

rekos

Uninstall:

py -m pip uninstall -y rekos

macOS / Linux

Install:

pipx install rekos --python python3.12

Run:

rekos

Uninstall:

pipx uninstall rekos

If your default Python is already >=3.10:

pipx install rekos

Latest version from GitHub

Use this only if you need fixes that are already on GitHub but not yet published on PyPI.

Windows PowerShell

py -m pip uninstall -y rekos
py -m pip install --force-reinstall git+https://github.com/VladTepes84/Rekos.git

macOS / Linux

python3 -m pip uninstall -y rekos
python3 -m pip install --force-reinstall git+https://github.com/VladTepes84/Rekos.git

If the rekos command is not found

Windows PowerShell

py -m pip show rekos
py -m rekos version

macOS / Linux

python3 -m pip show rekos
python3 -m rekos version

Run rekos with no arguments to open the quickstart screen.

Users run REKOS commands such as rekos investigate username <case> <username> and rekos investigate domain <case> <domain>. REKOS calls available passive sources through its source adapters and continues cleanly when optional external tools are absent.

Local development install

git clone https://github.com/VladTepes84/Rekos.git
cd Rekos
python -m venv .venv
. .venv/bin/activate
python -m pip install -e ".[dev]"
pytest
rekos

Optional Integrations

• sherlock enables the sherlock_username source when the sherlock command is installed
• maigret enables the maigret_username source when available in the REKOS runtime
• exiftool or mediainfo for file metadata collection
• Playwright is optional for URL screenshots; HTTP snapshots still work without it

Users always run rekos, not Sherlock or Maigret directly. rekos investigate username <case> <username> automatically uses the username sources available in the current environment.

Quick Start

rekos new-case social_test
rekos investigate username social_test username
rekos findings social_test
rekos findings social_test --verbose
rekos score social_test
rekos graph-summary social_test
rekos export-case social_test --output social_test.zip

Normal workflow:

1. Create a case with rekos new-case.
2. Add or investigate a target with rekos investigate username, rekos investigate domain, or rekos snapshot-url.
3. Review normalized results with rekos findings.
4. Score correlation quality with rekos score.
5. Inspect relationships with rekos graph-summary or rekos list-entities.
6. Export the workspace with rekos export-case.

Most users only need these commands:

rekos
rekos new-case acme-osint
rekos investigate username acme-osint alice.example
rekos investigate domain acme-osint example.com
rekos snapshot-url acme-osint https://example.com/profile/alice
rekos findings acme-osint
rekos findings acme-osint --verbose
rekos score acme-osint
rekos search acme-osint example.com
rekos graph-summary acme-osint
rekos export-case acme-osint --output ./acme-osint.zip

Use rekos findings <case> --verbose for grouped analyst detail. Add --show-uuids only when full finding IDs are needed.

Users run only rekos. Sherlock and Maigret are optional integrations that REKOS orchestrates internally when available.

During rekos investigate username <case> <username>, REKOS generates safe username variants, runs available passive username sources, stores raw source output, normalizes discovered profile URLs into findings, updates the entity graph, records timeline events, and computes correlation-quality scores. Results are correlation indicators, not proof of identity ownership.

During rekos investigate domain <case> <domain>, REKOS runs passive DNS, RDAP with registry/WHOIS fallback, HTTP/HTTPS endpoint checks, TLS certificate metadata collection, and crt.sh certificate transparency lookup when available. It records registration evidence, DNS records, web endpoint metadata, redirects, TLS certificate summaries, SPF/mail-security summaries, provider hints from TXT records, and certificate transparency findings.

Domain, URL, and snapshot workflows reject localhost, private/internal IP ranges, link-local addresses, metadata-service IPs, reserved, multicast, and unspecified IP targets. REKOS is for public-source targets only.

How REKOS Works

• Target input: user-provided usernames, domains, URLs, files, notes, and indicators are stored in a local case.
• Source orchestration: REKOS runs passive adapters such as username sources, DNS, RDAP/WHOIS fallback, web/TLS checks, crt.sh, Wayback, metadata tools, and HTTP snapshots when available.
• Findings normalization: raw source output is converted into normalized findings such as discovered profiles, URLs, domains, metadata records, archive records, and registration records.
• Graph correlation: entities and relationships connect usernames, profiles, domains, URLs, files, and notes.
• Quality scoring: REKOS scores correlation quality from source confidence, exact or normalized matches, duplicate source confirmation, evidence presence, and graph relationships.
• Evidence export: raw outputs, artifacts, reports, SQLite data, and manifests can be exported with rekos export-case.

Supported Sources

Source	Target types	Dependencies	Notes
sherlock_username	username	sherlock binary	Runs Sherlock with safe subprocess arguments and parses public profile URLs.
maigret_username	username	optional maigret package/tool	Runs Maigret when installed; REKOS continues without it.
wmn_username	username	none	Checks local public profile URL templates with conservative passive HTTP validation.
http_snapshot	url	none	Captures public HTTP response artifacts and optional Playwright screenshot.
rdap_domain	domain	none	Uses public HTTPS RDAP lookup with registry and WHOIS fallback where available.
dns_domain	domain	none	Fetches public DNS A/AAAA/MX/NS/TXT records and extracts SPF/provider hints.
web_domain	domain	none	Performs passive HTTP/HTTPS endpoint and TLS certificate metadata checks.
crtsh_domain	domain	none	Queries the public crt.sh certificate transparency endpoint.
wayback_url	url, domain	none	Queries public Wayback CDX data and records archive URLs.

Safety And Ethics

REKOS is passive-only OSINT tooling. Use it only for lawful, authorized, and ethical public-source research.

REKOS must not be used for:

• Logging into accounts or automating authenticated sessions
• Bypassing access controls, paywalls, CAPTCHAs, bot protection, or rate limits
• Credential collection, phishing, account abuse, or social engineering
• Exploitation, destructive operations, or aggressive crawling
• Claiming identity ownership from correlation results

Scores are correlation-quality indicators only. A high score means stronger local correlation support, not proof of identity, ownership, compromise, or intent.

Local Data Model

REKOS stores:

• Case metadata in SQLite
• Targets, entities, relationships, notes, timeline events
• Raw source outputs under exports/
• Evidence and snapshot artifacts
• Normalized findings with correlation-quality scores
• Case ZIP exports with manifest data

Development

python -m pip install -e ".[dev]"
pytest
rekos --help

Before submitting a change:

pytest
python -m compileall rekos
git diff --check

Roadmap

• More passive source adapters with explicit safety boundaries
• Stronger report templates and case export validation
• Improved graph summaries and finding explainability
• Better import/export interoperability
• Optional UI views while keeping the CLI and local-first storage as the core
