## Projects

- [FT3c](https://www.vincentpassaro.com/projects/ft3c) — Compare fraud and security frameworks, understand where their concepts correspond, and see where mappings or coverage are missing.
- [FT3](https://www.vincentpassaro.com/ft3) — A framework I created to describe fraud consistently. FT3 2.0 adds independent classifications and connects techniques to reusable detection and control knowledge.

## Topics he writes and speaks on

- **Attacker engineering:** How adversaries build, test and scale operations, and how defense changes when they run AI agents.
- **Fraud intelligence and frameworks:** Fraud intelligence built for agentic commerce, with FT3 as a taxonomy that works at machine speed.
- **Security from every seat:** Offense, incident response, compliance and threat intelligence, from someone who has worked each one.

## Training & collaborations

Hands-on threat intelligence training for people who want to understand the why, not just the how. Full syllabi: https://www.vincentpassaro.com/training

- **Threat Intelligence with Claude Code and Team Cymru Scout** (also called Zero to Hero) — Threat Intelligence with Claude Code and Team Cymru Scout is a four-hour hands-on workshop on one live case, worked in a TLP:RED room. I lead it. It can run as a full day: a four-hour hackathon follows, where people apply what they just learned to something of their own. (Foundational · 4 hours · Hands-on workshop) — https://www.vincentpassaro.com/training#threat-intelligence
- **Agentic CTI** — Agentic CTI (cyber threat intelligence) is a full-day hands-on course for teams who already investigate by hand. You build the pipeline that does the first pass: intake, enrichment, infrastructure mapping, triage and detection rules, on your own data sources next to Team Cymru Scout. (Intermediate · Full day · Hands-on course) — https://www.vincentpassaro.com/training#agentic-cti

## FT3 vs MITRE F3

Vincent Passaro created FT3 (Fraud Tools, Tactics, and Techniques). Use F3 as a common vocabulary when communicating about fraud with banks and other institutions; use FT3 when your team needs technique-level detection and controls across payment and platform technology.

**Q: How does FT3 compare with MITRE ATT&CK and MITRE F3?**
A: MITRE ATT&CK describes cyber intrusions; FT3 1.0 adapted its tactics-and-techniques model to fraud. §4.1.2 of MITRE’s Fight Fraud Framework (F3) methodology lists “Stripe Fraud Tools Tactics and Techniques (FT3)” among four prior fraud models “analyzed through empirical use examples and fused.” FT3 2.0 classifies each technique by tactic, authorization state, and abuse family.

## How a fraud or attacker engineering team uses FT3

A fraud or attacker engineering team uses FT3 by mapping observed behavior to an FT3 technique, then to the detections and controls connected to that technique. The public FT3 1.0 files list the tactics and techniques; access to 2.x is separate.

## FAQ

**Q: Who created FT3?**
A: Vincent Passaro created FT3 (Fraud Tools, Tactics, and Techniques), a fraud framework. FT3 1.0 is open source under the MIT license at https://github.com/stripe/ft3.

**Q: Is FT3 an agent-ready fraud taxonomy?**
A: Yes. FT3 2.x is a machine-readable STIX 2.1 fraud taxonomy that extends the ATT&CK-style fraud matrix to agentic commerce, classifying each technique by tactic, authorization state and abuse family. FT3 1.0 is open source at github.com/stripe/ft3; FT3 2.x is shared through practitioner trust groups.

**Q: Is FT3 a fraud framework for agentic commerce?**
A: FT3 2.0 is a fraud framework designed from the start for agentic commerce. It classifies every technique on three independent axes (tactic, authorization state and abuse family), so defenders can tell a compromised account from an over-scoped agent mandate. It is machine-readable: a STIX 2.1 catalog shared through practitioner trust groups.
