## 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.

- https://www.vincentpassaro.com/blog/ft3-vs-mitre-f3-operating-layer

## 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.

## Long-form context

### Why this site exists

vincentpassaro.com is the canonical reference for Vincent Passaro's professional identity — career arc, public work, speaking history, and contact details. It is intentionally built and kept narrow: no marketing funnel and no newsletter capture.

The site is intended to be cited and quoted by answer engines. AI crawlers are explicitly allowed in /robots.txt.

### What "Attacker Engineering" means here

Attacker engineering is building defensive systems, frameworks, and architecture backward from how attackers actually operate. It starts from attacker techniques and paths instead of a control checklist, so detection, fraud, identity, and platform teams use the same names for the same attacker behavior.

## Project overviews

### FT3c

Project: [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.

FT3c helps investigators and researchers compare fraud and security frameworks without losing the distinctions between them. Its crosswalk and graph catalog connects external concepts to FT3 and distinguishes reviewed mappings, proposals, gaps, and unassessed entries.

The implemented work includes mapping validation, machine\-readable graph and STIX exports, and coverage reports built against specific framework versions. I lead the project’s technical direction and mapping review.

The crosswalk, export pipeline, and MCP integration are implemented.

Current offering: Crosswalk validation, graph exports, and coverage reports.

#### More fraud frameworks, less shared language

Fraud now has more than one public matrix: FT3 and MITRE F3, alongside the security and compliance frameworks teams already use, such as ATT&CK and PCI DSS. Practitioners have to decide which framework to use, how each describes a fraud technique, and where they overlap.

#### Correspondence has a shape

A flat mapping says two concepts are linked. It does not say whether they are equivalent, whether the external concept is narrower or broader than FT3’s, or whether they only partly overlap. FT3c records which, so frameworks can be compared without losing those distinctions.

Equivalent: The same concept in both frameworks.

Narrower: The external concept is a specific case of the FT3 concept.

Broader: The external concept covers more than the FT3 concept.

Related: The concepts partly overlap.

No correspondence: FT3 has no matching concept. Recorded as a gap.

#### Every external concept has an explicit state

FT3c’s crosswalk and graph catalog connects concepts from external frameworks to FT3. Each entry is a reviewed mapping, a proposal, a gap, or unassessed, so a missing correspondence is never confused with one nobody has examined.

Reviewed mapping: A correspondence to FT3 confirmed by review. Only these count as coverage.

Proposal: A candidate correspondence awaiting review. Not counted as coverage.

Gap: Reviewed, with no corresponding FT3 concept.

Unassessed: Not yet reviewed. Recorded separately from a gap.

#### From PCI DSS v4.0.1 requirements, through FT3 controls, to fraud techniques

FT3c maps PCI DSS requirements to FT3’s security controls in a separate, typed control ledger. FT3 already records which fraud techniques each control mitigates or disrupts, so a compliance team can follow a requirement through its control to the fraud behavior it addresses.

135 of the 273 PCI DSS v4.0.1 requirements map to at least one FT3 control, reaching 13 of FT3’s 69 controls. The other 138 are gaps: 95 fall outside FT3’s control scope and 43 have no corresponding FT3 control.

Requirement → control: Each PCI DSS requirement is reviewed against FT3’s controls and mapped with a stated relationship type, or recorded as a gap.

Control → technique: The path to fraud techniques follows FT3’s own mitigates and disrupts relationships. FT3c does not collapse it into a direct requirement\-to\-technique mapping.

Outside control scope: Requirements with no FT3 control, such as governance and program\-management duties, are recorded as gaps.

Identifiers only: Outputs carry requirement identifiers and labels written for FT3c. PCI SSC text stays out of the catalog.

#### Built against specific framework versions

Mappings are validated before they enter the catalog. Graph exports, STIX exports, and coverage reports are built from the catalog against pinned framework versions, so each output refers to the releases it describes. The same catalog feeds FT3’s MCP integration.

#### Machine\-readable by design

Each build produces a combined STIX 2.1 bundle, RDF graphs in N\-Quads, and per\-framework coverage reports in CSV and Markdown. The exports are used within the project and are not distributed publicly.

Graph: RDF graphs of concepts and typed correspondences as nodes and edges.

STIX 2.1: A STIX 2.1 bundle, including FT3’s custom object types, for threat\-intelligence platforms.

Coverage reports: Per\-framework, per\-version reports of what is mapped and what is missing.

#### Frameworks crosswalked to FT3

A concept counts as covered when at least one reviewed mapping links it to FT3.

#### Frequently asked questions

#### About FT3c

FT3 is the ATT&CK\-style fraud framework, built for the future of agentic commerce. FT3c maps the other fraud frameworks to it, so practitioners can see how those frameworks relate to FT3 and to each other.

Author: Vincent Passaro

Integration: MCP integration · Built

Coverage: 1,387 concepts from 13 frameworks

Distribution: Not open source. Shared through trust groups.

Q: What is FT3c?
A: FT3c is the cross\-framework relationship catalog for FT3. It maps other fraud and security frameworks onto FT3, holds the result in a graph, and builds the combined catalog with a coverage report. Every external concept is reviewed and recorded as a typed mapping to FT3, a gap, or unassessed. It covers 1,387 concepts from 13 frameworks.

Q: How is FT3c different from FT3?
A: FT3 is the ATT&CK\-style fraud framework, built for the future of agentic commerce. FT3c is the mapping of other fraud frameworks to FT3. It solves a practitioner problem: understanding how the other frameworks relate to FT3 and to each other. FT3c depends on FT3; FT3 never depends on FT3c.

Q: How does FT3c map MITRE F3 and ATT&CK?
A: Mappings resolve through FT3. Each entry is anchored to the most precise FT3 concept \(a technique, tactic, or dimension\) with a typed relationship and a recorded review, or it is recorded as a gap. F3 and ATT&CK are compared through FT3, not mapped to each other directly; a chained match stays a candidate until it is reviewed. 101 of 123 F3 entries and 147 of 697 ATT&CK Enterprise entries are covered by reviewed mappings.

Q: Which frameworks are included?
A: MITRE Fight Fraud Framework \(F3\) \(v1.1\), MITRE ATT&CK Enterprise \(v19.1\), PCI DSS \(v4.0.1\), VERIS threat actions \(1.4.1\), GSMA telecom fraud \(v1\), PSR UK APP scam types \(Measure 1, cycle 3 \(Dec 2024\)\), SPF ScamShield scam types \(28 May 2026\), NPA special fraud \(Japan\) \(2026.4\), RBI Fraud Monitoring Return \(Circular 2024\-25/118\), MISP cryptocurrency\-threat \(v2\), MISP cryptocurrency\-market \(v1\), MISP carding \(v1\), OWASP Automated Threats \(Handbook 1.3\); pinned with ledgers under review: MITRE ATLAS \(2026.07\), EBA PSD2 fraud reporting \(GL/2018/05 \+ GL/2020/01\). Each is pinned to a specific release, and FT3 is the target they all map to.

Q: How does FT3c handle PCI DSS?
A: FT3c maps PCI DSS v4.0.1 requirements to FT3’s security controls in a separate control ledger, not to fraud techniques. All 273 requirements were reviewed: 135 map to at least one FT3 control and 138 are gaps. FT3’s own mitigates and disrupts relationships lead from each control to techniques. Outputs carry requirement identifiers and FT3c’s own labels, never PCI SSC text.

Q: What formats does FT3c export?
A: Each build produces a combined STIX 2.1 bundle \(every FT3 object plus external\-framework nodes, crosswalk relationships, and gap objects\), deterministic RDF graphs in N\-Quads, per\-framework coverage reports in CSV and Markdown, and an SSSOM mapping table. All are built against pinned framework versions. They are used within the project and are not distributed publicly.

Q: Who builds FT3c, and is it open source?
A: FT3c is authored by Vincent Passaro. It is not open source and is not published publicly. Like FT3 2.0, it is shared through trust groups: the communities where analysts, researchers, and threat hunters already share, teach, and solve problems, with reciprocity as the membership criterion.

### FT3

Project: [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.

FT3 gives fraud practitioners a shared way to describe behavior and connect that understanding to defensive work. I created the framework and continue to guide its evolution.

FT3 1.0 has publicly available source. The 2.x generation adds independent classifications and connected detection/control records; the selected catalog release is 2.1.0, dated 13 September 2026. Access to 2.x is by request.

Current offering: Versioned fraud framework. Public 1.0 source; 2.x access by request.

### ARC

Project: [ARC](https://www.vincentpassaro.com/projects/arc)

A threat intelligence platform \(TIP\) for querying, enriching, and visualizing relationships in a hypergraph. Its AI shows every query it runs and cites the nodes it used.

A threat investigation platform for querying, enriching, and visualizing complex relationships in a hypergraph, with AI\-assisted investigation workflows.

#### An IP address, a domain, a file hash, and a hosting provider are separate records until an analyst connects them.

ARC treats those connections as a hypergraph and reaches them through a query language built for pivoting: from a file hash to the domains it refers to, to the addresses they resolve to, to the provider that hosts them.

The query, its results, and the selected node’s properties, tags, and edges stay on one screen, so an analyst can pivot, filter, tag, and record findings without switching tools, whether tracking C2 infrastructure, hunting threats, or triaging indicators of compromise \(IOCs\).

#### An editor that knows the data model.

Autocomplete for node types \(forms\), properties, tags, and built\-in functions, with hover descriptions drawn from the hypergraph’s own data model. Syntax highlighting and Vim and Emacs keybindings are included. Built on CodeMirror 6.

Beyond full queries, the query bar has a Lookup mode for finding existing indicators and an Auto Add mode for creating new ones, so pasted indicators can be found or added in one step. The same queries power the AI\-assisted investigation below.

#### Ask in plain language and see the query before it runs.

Ask mode turns a question into a query and shows it before anything runs. The Analysis Sidebar takes on a whole line of inquiry: it plans the pivots, runs the queries, interprets the results, and cites the nodes it used.

The model is a setting, not a dependency. A local model through Ollama keeps investigation data inside the network ARC runs on.

Providers: Claude, OpenAI, Ollama, or any OpenAI\-compatible endpoint

Sent: The question, the schema, and node summaries

Guardrails: Read\-only by default; write queries need approval

#### I wanted agentic analysis on structured threat intelligence, in a platform built around how I work.

I designed and built ARC myself, on my own time, as an advanced research project. I started in February 2026. At the time, I couldn’t find an openly available way to bring agentic analysis to structured threat intelligence: an assistant that works through the graph itself.

I also wanted a threat intelligence platform \(TIP\) I could shape to my own workflows. The Analysis Sidebar is the clearest result. I give it a question, and it plans the pivots, runs the queries, interprets what comes back, and cites the nodes it used.

Two decisions shaped the AI features. Every query the AI runs is visible, and write queries wait for my approval, so I can check the reasoning before I trust the answer. And the model is my choice: Claude, OpenAI, Ollama, or any OpenAI\-compatible endpoint. With a local model, investigation data stays inside the network.

ARC is currently available only through trust groups. It is the platform I use for my own investigations and research.

#### Frequently asked questions about ARC

Q: What is ARC?
A: ARC \(Advanced Research Capability\) is a browser\-based threat intelligence platform \(TIP\) for querying, enriching, and visualizing relationships in a hypergraph, with optional AI that shows every query it runs and cites the nodes it used. Vincent Passaro designed and built it as a research project and uses it for his own investigations. The relationships it traces link IP addresses, domains, file hashes, and hosting infrastructure.

Q: Who built ARC?
A: Vincent Passaro designed and built ARC himself, on his own time, as an advanced research project; it was not built for an employer. He started it in February 2026 and develops it solo.

Q: Why was ARC built?
A: Vincent Passaro built ARC to bring agentic analysis to structured threat intelligence and to have a threat intelligence platform \(TIP\) he could customize to his own workflows. ARC’s Analysis Sidebar is the clearest result: given a question, it plans the pivots, runs the queries, and cites the nodes it used.

Q: Who uses ARC?
A: Vincent Passaro uses ARC as his working threat intelligence platform for his own investigations and research. ARC is currently available only through trust groups. Its workflows are built around threat intelligence analysis: tracing how indicators, infrastructure, and threat actors connect.

Q: How does ARC use AI?
A: ARC uses AI in two optional features. Ask mode turns a plain\-language question into a query and shows it before anything runs. The Analysis Sidebar takes on a whole line of inquiry: it plans the pivots, runs the queries, interprets the results, and cites the nodes it used. AI queries are read\-only by default, and write queries need analyst approval.

Q: Is ARC open source or publicly available?
A: ARC is closed source and currently available only through trust groups. The libraries it is built on are open source, including React, TypeScript, CodeMirror 6, Cytoscape.js, and MapLibre.

Q: What is a hypergraph?
A: A hypergraph, the data model ARC works with, is a graph in which one relationship can link any number of nodes. In ARC, indicators, infrastructure, and threat actors are nodes in a hypergraph, reached with a hypergraph query language.

Q: What query language does ARC use?
A: ARC uses the query language of the hypergraph service it connects to, a language built for filtering and pivoting across nodes and their relationships. ARC’s editor adds autocomplete for node types, properties, tags, and functions, hover descriptions drawn from the data model, and Vim and Emacs keybindings. Ask mode can also write a query from a plain\-language question and show it before it runs.

Q: How does ARC connect to its data?
A: ARC is a browser\-based frontend and does not include its own backend. It connects to a hypergraph service over HTTP and WebSocket, and that service stores the data and runs the queries. ARC and the hypergraph service can both be self\-hosted, so investigation data stays inside the environment they run in.

Q: Which AI models does ARC support?
A: ARC works with Claude, OpenAI, Ollama for local models, and any OpenAI\-compatible endpoint. In ARC, the model is a configuration choice, not a dependency.

Q: What data does ARC send to the AI provider?
A: ARC sends the AI provider the question, the data schema, and summaries of the relevant nodes. With a local model through Ollama, that data does not leave the network ARC runs on.

Q: Are ARC’s AI features required?
A: ARC’s AI features are optional. Without a configured provider, Ask mode and the Analysis Sidebar are hidden and the rest of ARC works the same.

### Acheron

Project: [Acheron](https://www.vincentpassaro.com/projects/acheron)

A private research engine that proposes candidate additions to FT3 for its maintainers to review.

Acheron turns fraud intelligence into proposed additions to FT3. Agents identify the techniques described in incoming intelligence and prepare evidence\-backed proposals; FT3 maintainers decide what is added.

FT3 2.0 is supported by Acheron, a private, intelligence\-assisted research environment that turns raw fraud intelligence into reviewable proposals for governed, versioned FT3 knowledge, while preserving provenance.

Acheron helps turn live threat intelligence into a machine\-readable map of how fraud actors operate. I wrote in May that the next phase of fraud defense was making adversary language run. FT3 2.0 is that phase, and Acheron is the agentic research system that proposes its new techniques.

Current state: Private and not publicly available. Acheron prepares proposals; FT3 maintainers decide what is accepted.

#### Analysts spend their week reading reports to find the one behavior the framework hasn't named yet.

Acheron does that reading overnight, so your team starts the morning deciding what to defend against.

#### How Acheron turns threat reporting into FT3 proposals

Four stages, each run by agents. The output is always a proposal, never a change to FT3.

Behavior, not keywords.: Agents extract what the actor actually did: who acted, the action, the mechanism, and whether it was observed, reported, or only a capability. Every claim points to the source passage it came from, and inferences are labelled as inferences.

A second model tries to prove the first one wrong.: A separate reviewer, working from fresh context, hunts for omissions and unsupported assertions across the whole report. Claims that cannot point to a source passage are removed, and a recall check sends back behaviors the initial pass missed.

Every observation meets every technique.: Each fraud observation is compared against every FT3 record, not a retrieved shortlist, so a familiar label cannot hide a different behavior and partial coverage can still add new evidence.

A candidate with its receipts attached.: Acheron drafts a new technique, an enrichment, or a revision in FT3's own language, with the source evidence attached, and files it for maintainers to decide. It never merges, promotes, or releases anything.

#### Agents did the reading. You make the call.

In this illustrative run, crawler agents pull four relevant items from an overnight feed. Agent A drafts findings from them, and Agent B checks each one against its source while A is still drafting. B rejects a claimed loss figure that one source contradicts, and a recall check sends back a behavior A missed. The verified findings become a proposed technique, compared against every FT3 technique, that waits for one human decision.

#### A fake wallet package FT3 had no name for.

Acheron's agents found a malicious npm package posing as a wallet brand to steal crypto wallets and credentials, and proposed it as a new FT3 behavior.

It came from one pilot run: 21 fraud behaviors checked against all 263 FT3 techniques, 13 proposals filed, six of them new behaviors. All 13 are waiting on FT3's maintainers.

#### Frequently asked questions

Q: What is Acheron?
A: Acheron is a private, agent\-driven research system built by Vincent Passaro. It reads fraud and threat intelligence, extracts the behaviors actors actually used, compares each one against every technique in FT3, and prepares evidence\-backed proposals for new techniques or improvements that FT3 maintainers review.

Q: How does Acheron find new fraud techniques?
A: Agents extract source\-grounded behaviors from reporting. A second model challenges every claim and removes anything without a source passage, and a recall check recovers behaviors the initial pass missed. Each remaining observation is compared against every FT3 technique, and behaviors no technique covers become candidate proposals.

Q: Does a human review Acheron's output?
A: Yes. The research is agent\-driven; the decision is not. Acheron does not author FT3 records, merge changes, or make taxonomy decisions. Every proposal stays a candidate until FT3 maintainers decide what becomes framework knowledge.

Q: How is Acheron related to FT3?
A: FT3 is a public framework of fraud tactics and techniques, often described as MITRE ATT&CK for fraud. Acheron is a separate, private research system that proposes additions and improvements to FT3. It does not change the framework itself.

Q: Has Acheron added techniques to FT3?
A: Not yet. Its pilot filed 13 reviewed proposals into FT3's intake queue, six of them proposed new behaviors. As of November 2026 none has been decided; each waits for FT3 maintainers.

Q: Can I use Acheron?
A: No. Acheron is private and used only by FT3's maintainers, who review every proposal it files. If you want to know how it works, get in touch.

### Aqueduct

Project: [Aqueduct](https://www.vincentpassaro.com/projects/aqueduct)

Compliance remediation content for Red Hat Enterprise Linux: Bash, Puppet, and Ansible, organized as one script per STIG finding.

I created Aqueduct to share DISA STIG remediation for Red Hat Enterprise Linux. The original project, on Fedora Hosted, set out to share system configuration content and the methods for synchronizing that content to systems management tools such as Red Hat Network Satellite.

The public repository is organized by tool and finding. Bash STIG scripts for RHEL 5 and RHEL 6 each stand alone, in production, in\-development, and manual\-check trees, so one finding can be audited or changed without the others. Puppet modules cover the RHEL 6 STIG. An Ansible role covers RHEL 6 SCAP Security Guide hardening. An RPM spec packages the content for installation. I wrote most of the Bash scripts. Shannon Mitchell contributed some of the RHEL 5 scripts and the RPM packaging.

The work is under GPL\-2.0. The repository README describes Aqueduct as a historical project from 2011 to 2014, kept so the scripts remain public.

Current state: Public source. Historical RHEL 5 and RHEL 6 remediation content from the Fedora Hosted project.

Languages and technologies: Bash, Puppet, Ansible

#### Frequently asked questions

Q: What was Aqueduct?
A: Aqueduct \(2011–2014\) was an open\-source project, created by Vincent Passaro on Fedora Hosted, that published Bash, Puppet and Ansible scripts to fix DISA STIG findings on Red Hat Enterprise Linux 5 and 6, one script per finding. It supplied the remediation half while SCAP Security Guide, now called ComplianceAsCode, supplied the checks.

Q: Who created Aqueduct?
A: Vincent Passaro created Aqueduct in 2011 on Fedora Hosted and wrote most of its DISA STIG Bash content: 550 of its 734 RHEL 5 scripts name him as initial author. Shannon Mitchell, Leam Hall, Maura Dailey and Bill Carlson also contributed.

Q: How did Aqueduct relate to SCAP Security Guide \(ComplianceAsCode\)?
A: They started as partners. SCAP Security Guide wrote the checks and, in October 2011, removed its own deployment files because "Aqueduct is the place for that." In 2013 SSG chose to embed short per\-rule Bash fixes inside its own XCCDF content instead of linking to Aqueduct's larger STIG scripts. Red Hat's Shawn Wells later wrote that "many of the remediation scripts originated from Aqueduct."

Q: How much did Aqueduct improve STIG compliance?
A: In October 2012 Shawn Wells of Red Hat scanned a RHEL 5 system with oscap against DISA's RHEL 5 V1R1 benchmark \(350 rules\). Passing checks rose from 198 \(57%\) before Aqueduct to 278 \(80%\) after, and the script run took 3 minutes 12 seconds.

Q: Why did Aqueduct use Bash instead of Puppet?
A: Bash shipped on every RHEL system, while Puppet needed a paid license to meet the vendor\-support rule some Navy and Marine Corps programs followed. In 2012 Vincent Passaro wrote that "using bash encourages more contributions from the community." Puppet modules for the RHEL 6 STIG were added in 2013 and an Ansible role in 2014.

Q: What happened to Aqueduct?
A: The code moved from Subversion to Git in May 2013 and to GitHub as BuddhaLabs/Aqueduct in December 2013. The last commit was on 17 October 2014. Fedora later retired fedorahosted.org, taking the wiki, Subversion history and private mailing list with it. The GitHub repository, public list archives and Wayback Machine captures survive.

Q: Can I still use Aqueduct to STIG a RHEL system?
A: Aqueduct's scripts target the RHEL 5 and RHEL 6 STIGs and have not been updated since October 2014. Its approach of shipping a fix with each check continued in SCAP Security Guide, which first shipped in RHEL 6.6 in 2014 and is now maintained as ComplianceAsCode.

#### Aqueduct by the numbers

The surviving repository, https://github.com/BuddhaLabs/Aqueduct (created 6 December 2013; Git history from 31 May 2013), holds 1,255 Bash scripts: 734 for the RHEL 5 STIG (493 production, 163 development, 78 manual), 256 for the RHEL 6 STIG (56 production, 182 development, 18 manual-check) and 265 written for SCAP Security Guide rules. It also holds 23 Puppet modules for the RHEL 6 STIG and one Ansible hardening role. Its last commit is dated 17 October 2014. The project wiki listed DISA STIG, USGCB, CIS, NISPOM, PCI, HIPAA, DHS guidance; only the STIG and SSG content survives in Git. License: GPL-2.0-or-later.

### OSINT desk toolkit

Project: [OSINT desk toolkit](https://www.vincentpassaro.com/projects/osint-desk-toolkit)

A case desk for public\-source investigations: collection, resolution, verification, and a report, split across specialist roles.

The OSINT desk toolkit gives an investigation one case record and separates who may do what. A handler coordinates the case. A collector gathers public\-source material. A resolver and a verifier work the results. Playbooks describe the investigative method. Role instructions say who may write which records.

A case holds the questions, task tickets, captured artifacts, observations, entities, edges, assessments, hypotheses, and a versioned report. Scripts open a case, say which role to prompt next, claim and finalize tasks, validate the case, and seal an export. A leads index is rebuilt from sealed cases. Offline fixtures and automated tests cover correlation scenarios without calling live services.

Passive collection adapters in the repository cover keyless public sources, including registration data, historical page snapshots, and DNS. A capability inventory separates those adapters from services that still need a key, and from names that are only a catalog reference. Listing a service is not the same as having it connected. The person running the desk prompts the roles and commits the code. The roles do not commit case data.

Current state: Case schema, role playbooks, desk scripts, passive adapters, and offline tests are in the repository. Keyed services stay unconnected until they are configured.

Languages and technologies: Python, Shell

Talks in the PDF speaker kit:

- **FT3 Evolution: From Static Classification to Living Agentic Framework** — Presentation, 45 min. RISE-X NYC, New York, 2026-06-16. Also given as “FT3: The Industry’s First Agentic ATT&CK-Style Matrix” at Intel471 CyberCon, Frisco, Apr 2026, and as “Fighting Fraud with FT3” at Intel471 Unconference, San Diego, Feb 2026.
  This session will provide a builder’s view of how fraud intelligence must evolve as adversaries use AI to accelerate their tactics. The next evolution is making that language operational, adaptive, and usable inside real investigative and intelligence workflows.
- **When Both Sides Have Agents: Attacker Engineering at Machine Speed** — Presentation, 45 min. RBLN West, San Francisco, 2026-11-04.
  The next attacker may not need to break in. In agentic systems, an action can be permitted—and still adversarial. This talk moves beyond asking an LLM to just threat model and into model reasoning.
- **Simple and Complex Environments: A Service Provider’s Perspective** — Presentation, 30 min. PCI SSC, Vancouver, BC, 2026-09-16.
  In this talk, Stripe shares practical observations from the field describing “simple” environments where merchants rely largely on service providers for payment processing and contrasts those with “complex” environments that directly contact or retain card data.

#### Threat Intelligence with Claude Code and Team Cymru Scout

Also called Zero to Hero. Foundational · 4 hours, or a full day with the hackathon · Hands-on workshop
https://www.vincentpassaro.com/training#threat-intelligence

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.

- **Who it’s for:** Threat-intelligence analysts and investigators. You don’t need to have used Claude Code before
- **Before you come:** A laptop with Git and a terminal. You run one pre-flight script before the day. Claude Code and Team Cymru Scout access are issued for the session
- **Tools:** Claude Code, Team Cymru Scout MCP

**The four hours**

- Before the day: Pre-flight (Before you arrive): One script checks your terminal, Claude Code, the Team Cymru Scout API and MCP tools, so the room starts on the case.
- 1. How Claude thinks (15 min): The context window, what happens as it fills, and why plan mode, focused tasks, supervision and fresh sessions all follow from it.
- 2. Orientation (20 min): The case brief and its two reported addresses. Two ways into Team Cymru Scout: its Model Context Protocol (MCP) server for investigating, the REST API for building.
- 3. Investigate (30 min): Compare the two addresses on live data, pull the stronger lead apart, interrupt a run that drifts, and rank each pivot as high-signal, noisy or a dead end.
- 4. Prove it (30 min): Audit the output for claims the data never returned. Re-run it with every claim labelled observed or inferred, then save a case file another analyst can check.
- 5. Own your tooling (30 min): Write your method down as a playbook, package it as a skill Claude loads on the next case, and test that it triggers without being named.
- 6. Build the team (35 min): Set a research boundary, then write two roles: an investigator that only gathers and a reviewer whose only job is to refute.
- 7. Run the team (25 min): Run the cycle on your own case, write the threat report from what survived review, and read what the reviewer rejected.
- Optional: Hackathon (Optional · 4 hours): Teams of three to five take what they built in the workshop and apply it to an idea of their own, with me still in the room. Three hours to build, one to show the room.

**You leave with**

- A case file with every claim labelled observed or inferred
- An investigation skill that loads on your next case
- An investigator and reviewer agent team that writes the report
- Five follow-up modules for the first week back

#### Agentic CTI

Intermediate · Full day · Hands-on course
https://www.vincentpassaro.com/training#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.

- **Who it’s for:** Threat-intelligence teams already doing investigations by hand
- **Before you come:** Working threat-intel experience. Some scripting helps
- **Tools:** Claude Code, MCP

**Modules**

- 1. From one case to a pipeline: What changes when an investigation has to run every day without you starting it.
- 2. Live telemetry through MCP: Connect your own data sources next to Team Cymru Scout as MCP servers, and decide which path feeds the agent and which feeds code.
- 3. IOC intake and enrichment: Deduplicate a messy feed, enrich it across sources, and score each indicator with a sourcing chain an analyst can audit.
- 4. Mapping adversary infrastructure: Expand a seed set through certificates, fingerprints and peers, and rank every pivot by how specific the link is.
- 5. Timelines you can defend: Rebuild when infrastructure appeared and changed, then package it as STIX with every timestamp tied to a tool result.
- 6. Triage with a reviewer in the loop: First-pass triage run by an investigator and a reviewer agent, with a person making the final call.
- 7. From finding to detection: Turn what the pipeline found into Sigma and YARA rules, and test them against baseline data.

**You leave with**

- An enrichment pipeline whose scores you can trace to a source
- An infrastructure-mapping workflow on your own telemetry
- A triage loop with a reviewer agent and a human sign-off
- Detection rules generated from a case and tested

#### How rooms scored the Threat Intelligence course

- Instructors and mentors: 93%. 39 of 42 respondents across both sessions picked the instructors and mentors as something that worked well.
- Net Promoter Score: 72. In Strasbourg, 23 of 29 respondents scored 9 or 10 out of 10 on recommending it: a Net Promoter Score of 72.
- Poor ratings: 0. None of the 47 respondents, across both sessions, rated any section of the course Poor.

### Canonical Q&A

**Q: Who is Vincent Passaro?**
A: Vincent Passaro is Head of Attacker Engineering & Intelligence Partnerships at Stripe and creator of FT3. He has spent two decades studying adversary behavior, strengthening complex systems, and building offensive-informed defense, from intel-side analysis to Tier-3 incident response at Amazon to architecture at Stripe.

**Q: What is FT3?**
A: FT3 (Fraud Tools, Tactics, and Techniques) is a fraud framework created by Vincent Passaro. It gives fraud teams a consistent way to describe attacker behavior, compare cases, and connect each technique to the knowledge needed to investigate it. FT3 1.0 is open source under the MIT license at github.com/stripe/ft3. FT3 2.x is not distributed through a public repository; Vincent Passaro shares it through vetted TLP trust groups and by direct request. The canonical overview is https://www.vincentpassaro.com/ft3.

**Q: How can I contact Vincent Passaro?**
A: You can reach Vincent at hello@vincentpassaro.com for speaking, advisory, and collaboration. I usually reply within five business days.

**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.
