Add MITRE Fight Fraud Framework (F3 v1.1) mappings to fraud-relevant skills

Browse Source 
- Add mitre_f3 frontmatter block to 94 fraud-relevant skills (phishing,
  account takeover, banking malware, BEC, identity/KYC, payment/card fraud,
  money-mule/cash-out, ransomware extortion, DFIR, threat intel)
- Map each skill to F3 v1.1 tactics + precise technique IDs, including the
  two F3-specific tactics ATT&CK lacks: Positioning (FA0001) and
  Monetization (FA0002)
- All 123 F3 v1.1 technique IDs validated against the upstream STIX bundle
  (github.com/center-for-threat-informed-defense/fight-fraud-framework):
  0 invalid IDs, 0 invalid tactics, 0 name mismatches, no placeholder IDs
- mitre_f3 kept as a separate block from mitre_attack (F3 redefines several
  ATT&CK tactics for the fraud context)
- Add docs/mitre-f3-mapping.md schema reference
- Update README: F3 as the 6th framework, dedicated F3 section + badge

A junior analyst knows which Volatility3 plugin to run on a suspicious memory dump, which Sigma rules catch Kerberoasting, and how to scope a cloud breach across three providers. **Your AI agent doesn't — unless you give it these skills.**
This repo contains **754 structured cybersecurity skills** spanning **26 security domains**, each following the [agentskills.io](https://agentskills.io) open standard. Every skill is mapped to **five industry frameworks** — MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, and NIST AI RMF — making this the only open-source skills library with unified cross-framework coverage. Clone it, point your agent at it, and your next security investigation gets expert-level guidance in seconds.

### 🆕 MITRE Fight Fraud Framework (F3) — 94 fraud-relevant skills
[![MITRE F3](https://img.shields.io/badge/MITRE-F3_v1.1-blue?style=flat-square)](https://ctid.mitre.org/fraud/)
The **[MITRE Fight Fraud Framework (F3)](https://ctid.mitre.org/fraud/)** was released **April 9, 2026** by MITRE's Center for Threat-Informed Defense (CTID), co-developed with JPMorganChase, Citigroup, Lloyds Banking Group, Standard Chartered, CrowdStrike, Verizon Business, FS-ISAC, and others. It is an ATT&CK-compatible TTP catalog for **cyber-enabled financial fraud** — filling the gap ATT&CK leaves after initial compromise.
F3 v1.1 adds **two fraud-specific tactics** that ATT&CK does not enumerate:
- **Positioning** (`FA0001`) — actions taken after access to collect/manipulate data and prepare the fraud (synthetic-identity seeding, account warming, beneficiary setup, SIM-swap pre-positioning, banking-session hijack).
- **Monetization** (`FA0002`) — converting stolen assets into usable funds (money-mule layering, APP fraud, crypto off-ramping, card cash-out, refund/chargeback abuse).
Fraud-specific techniques use `F1XXX` IDs (e.g. `F1005.003` Add Beneficiary, `F1025.003` Wire Transfer, `F1007` Adversary-in-the-Browser); reused ATT&CK techniques keep their `T1XXX` IDs. Mappings live in each skill's `mitre_f3:` frontmatter block — all 123 F3 v1.1 technique IDs were verified against the upstream STIX bundle. See [`docs/mitre-f3-mapping.md`](docs/mitre-f3-mapping.md) for the schema.
