OSINT book
OSINT Techniques
Michael Bazzell
The practical field manual most investigators mean when they say “the Bazzell book.” Current editions focus on self-hosted VMs, people and social search, breach and stealer data, and a repeatable investigation workflow — not theory for its own sake.
Who it’s for
- Private investigators and corporate investigators building a first real desk
- Journalists and NGO researchers who need current platform techniques
- SOC / CTI analysts who want hands-on collection, not only alert enrichment
What you get
- Edition-length coverage of VMs, browsers, search, social platforms, and identifiers
- Sections on leaks, breaches, stealer logs, and documentation habits
- Companion digital files and VM build notes via the publisher (per IntelTechniques)
How to use it
- 01
Build the environment first
Follow the VM and browser chapters before you chase subjects. A clean desk beats a clever query on a contaminated machine.
- 02
Work one identifier type at a time
Email, username, phone, image — finish a pass before pivoting. The book’s strength is breadth; your job is sequence.
- 03
Expect the UI to drift
Platform menus change. Keep the methodology (document, corroborate, stop) and treat named UI steps as snapshots.
Strengths
- Updated often enough to stay operationally useful
- Covers the full modern stack: people, social, infra-adjacent, and breach data
- Written for people who will run real cases, not only classroom demos
Watch out for
- Tool URLs and platform steps age between editions
- North America–heavy examples; adapt for other jurisdictions
- Dense — skim for your case type, then deep-read what you will actually run

Extreme Privacy
A task-oriented privacy and disappearance manual: accounts, data brokers, devices, and lifestyle compartmentation. Investigators read it to understand how subjects (and themselves) leave or erase traces — not as a substitute for an OSINT search syllabus.

FAQ
Questions, answered
Is this the same as “Open Source Intelligence Techniques”?
Yes — marketing titles vary by edition. IntelTechniques currently lists it as OSINT Techniques. Same author, same lineage.
Do I need every edition?
No. Buy the latest you can afford, then follow the IntelTechniques blog for post-publication updates. Old editions are still useful for methodology.
