Extract DPAPI-protected secrets such as credentials and browser data offline and online.
Take over Active Directory user and computer accounts by writing alternate certificate keys to msDS-KeyCredentialLink (Shadow Credentials) with pyWhisker, Whisker, and Certipy, then authenticate via PKINIT.
Prepare a defense-contractor environment for CMMC Level 2 certification: scope CUI and FCI, implement the 110 NIST SP 800-171 Rev 2 security requirements across 14 families, compute the SPRS score with the DoD Assessment Methodology, manage a compliant POA&M, and ready the organization for a C3PAO assessment. Use when an organization handles Controlled Unclassified Information (CUI) under a DoD contract, when a contract carries DFARS clause 252.204-7012/7019/7020/7021, when preparing for or responding to a CMMC assessment, when computing or improving an SPRS score, when building a System Security Plan or POA&M for 800-171, or when scoping which systems are in the CUI boundary. Keywords: CMMC, CMMC Level 2, NIST 800-171, SP 800-171 Rev 2, CUI, FCI, SPRS, DFARS 7012, C3PAO, POA&M, System Security Plan, DoD Assessment Methodology, 110 controls, defense industrial base, DIB, FedRAMP equivalency.

⚠️ Community Project — This is an independent, community-created project. Not affiliated with Anthropic PBC.
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 817 structured cybersecurity skills spanning 29 security domains, each following the agentskills.io open standard. Every skill is mapped to six industry frameworks — MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, NIST AI RMF, and the MITRE Fight Fraud Framework (F3) — 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.
No other open-source skills library maps every skill to all of these frameworks. One skill, six compliance checkboxes.
| Framework | Version | Scope in this repo | What it maps |
|---|---|---|---|
| MITRE ATT&CK | v19.1 | 15 tactics · 286 techniques | Adversary behaviors and TTPs |
| NIST CSF 2.0 | 2.0 | 6 functions · 22 categories | Organizational security posture |
| MITRE ATLAS | v5.4 | 16 tactics · 84 techniques | AI/ML adversarial threats |
| MITRE D3FEND | v1.3 | 7 categories · 267 techniques | Defensive countermeasures |
| NIST AI RMF | 1.0 | 4 functions · 72 subcategories | AI risk management |
| MITRE F3 (Fight Fraud Framework) | v1.1 (2026-04-09) | 8 tactics · 123 techniques · 94 fraud-relevant skills | Cyber-enabled financial fraud TTPs |
Example — a single skill maps across all six:
| Skill | ATT&CK | NIST CSF | ATLAS | D3FEND | AI RMF | F3 |
