{"page":{"pageid":174,"slug":"skills-anthropic-cybersecurity-skills","title":"mukul975/Anthropic-Cybersecurity-Skills (817 security skills)","content":"**What it is.** The largest open cybersecurity skill library for agents: 817 structured skills across 34 domains, mapped to MITRE ATT&CK v19, ATLAS, D3FEND, the MITRE Fight Fraud Framework, and NIST AI RMF. Despite the name it is a community project, not Anthropic's. Offensive skills (C2 operation, NTLM relay) sit next to defensive ones; read [[untrusted-content-and-security]] and use them only with authorisation.\n\n| | |\n| --- | --- |\n| Upstream | [mukul975/Anthropic-Cybersecurity-Skills](https://github.com/mukul975/Anthropic-Cybersecurity-Skills) |\n| License | Apache-2.0 |\n| Author | mukul975 |\n| Stars (at fetch) | 32,539 |\n| Fetched | 2026-09-10 |\n\n## Install\n\n- `npx skills add mukul975/Anthropic-Cybersecurity-Skills` (all 817, large) or `--skill <name>`; or clone and copy the domains you need.\n\n## Skills\n\n| Domain | Skills |\n| --- | --- |\n| Cloud Security | 66 |\n| SOC Operations | 63 |\n| Threat Hunting | 58 |\n| Threat Intelligence | 52 |\n| Web Application Security | 46 |\n| Network Security | 43 |\n| Digital Forensics | 41 |\n| Identity and Access Management | 40 |\n| Malware Analysis | 39 |\n| Red Teaming | 35 |\n| Container Security | 33 |\n| OT/ICS Security | 29 |\n| API Security | 28 |\n| Incident Response | 26 |\n| Vulnerability Management | 25 |\n| Penetration Testing | 23 |\n| DevSecOps | 18 |\n| Zero Trust Architecture | 18 |\n| Endpoint Security | 17 |\n| Phishing Defense | 16 |\n| Cryptography | 16 |\n| AI Security (LLM red-teaming, prompt injection, MCP/agentic security) | 14 |\n| Mobile Security | 13 |\n| Ransomware Defense | 13 |\n| Compliance and Governance | 10 |\n| Supply Chain Security | 8 |\n| Threat Detection | 7 |\n| Hardware and Firmware Security | 6 |\n| Deception Technology | 6 |\n| Blockchain, Wireless, Privacy Compliance, Data Protection, Purple Team | 8 |\n\nEvery skill is `skills/<name>/SKILL.md` with YAML front matter that maps it to MITRE ATT&CK, ATLAS, D3FEND, the F3 fraud framework, and NIST AI RMF.
