This document summarizes all OSINT tools used across the investigation workflow. It covers every major part of modern open-source intelligence: blockchain tracing, infrastructure lookups, metadata extraction, credential reconnaissance, dark-web analysis and automation.
The list is structured to match the real investigative workflow.
1. Blockchain Analysis Tools

- BTC.com – Bitcoin explorer
- Blockchain.com Explorer
- Blockscan – EVM-focused multi-chain explorer
Chain-specific explorers
- Mempool.space – Bitcoin mempool & on-chain analytics
- Etherscan, BscScan, Polygonscan, Arbiscan
- Solscan / Solana Explorer
- TronScan
Graph analysis / attribution
- Breadcrumbs – easy-to-use visual tracing
- GraphSense – open-source chain analysis
- OXT.me – Bitcoin graph analytics
- Crystal Blockchain – professional platform
- Chainalysis Reactor / TRM Labs – enterprise-grade
Risk scoring / off-ramp identification
- Elliptic – entity attribution, risk scoring
- AMLBot – wallet risk assessments
- XTblock – multi-chain risk indicators
2. Infrastructure OSINT
Tools for mapping servers, domains, IPs, DNS history and backend infrastructure.
DNS / IP Intelligence
- SecurityTrails – historical DNS, subdomains, WHOIS
- Shodan – exposed services, banners, CVEs
- Censys – certificates, hosts, fingerprints
- FOFA – Chinese alternative to Shodan
- ViewDNS.info – quick multi-lookup
- DNSDumpster – subdomain discovery
Certificates
- crt.sh – certificate transparency logs
- CertSpotter – domain monitoring
Routing & Netblocks
- Hurricane Electric BGP Toolkit
- RIPEstat – IP allocations, ASN info
3. Metadata & File Intelligence
Tools for extracting EXIF data, document metadata, file hashes and digital footprints.
Metadata extraction
- ExifTool – best tool for EXIF and file metadata
- FOCA – scanning public documents for metadata
- mat2 – metadata anonymization (Linux)
File and hash lookup
- VirusTotal – malware scans, hash intelligence
- Hybrid Analysis – behavioral malware analysis
- Malshare / Malpedia
4. Social & Human OSINT
Tools used for researching online profiles, usernames, email addresses and identities.
Person search
- OSINT Framework (index)
- SpiderFoot – automated recon
- Pipl (limited)
- Truecaller (phone lookup)
Username & handle investigation
- WhatsMyName – search username across platforms
- NameCheckup
- Maigret – OSINT username scanner
Email intelligence
- HaveIBeenPwned – breach data
- Epieos – email footprint
- Holehe – checks if email exists on major services
5. Dark Web & Deep Web Tools
- Ahmia – Tor search
- OnionSearch – OSINT CLI tool
- DarkSearch.io
- Tor Browser (mandatory for verification)
6. Recon Automation & Intelligence Platforms
Automation & scanning
- SpiderFoot HX
- Maltego – graph intelligence
- Recon-ng – modular recon
- theHarvester – email & domain harvesting
Containers & scripting
- Dockerized OSINT environments
- Python notebooks for OSINT automation
7. Visualisation & Reporting
- Maltego – graph analysis
- Obsidian – investigation documentation
- Hugo (SystemLog) – publishing results
- draw.io / Excalidraw – mapping infrastructure
- Gephi – network graph visualization
8. Workflow Summary
A typical OSINT investigation follows this structure:
- Initial scoping
- identify entity, wallet, domain, username, server
- Infrastructure OSINT
- DNS, IP, netblocks, certificates, subdomains
- Blockchain tracing (if crypto is involved)
- explorer → graphing → entity attribution
- Human OSINT
- usernames, emails, social profiles
- Threat attribution
- clustering, intersection of data sources
- Report generation
- structured, visual, reproducible
Conclusion
This toolkit provides a unified set of tools suitable for:
- cybercrime investigation
- blockchain tracing
- digital forensics
- OSINT automation
- intelligence reporting
It forms the backbone of the SystemLog OSINT workflow, supporting both field work and analytical investigations.
