Top Claude Skills for Security Professionals in 2026

Security professionals spend enormous amounts of time on repetitive, detail-intensive tasks: sifting through file metadata, running wordlist-based fuzzing campaigns, auditing code for OWASP vulnerabilities, and piecing together forensic timelines. Claude Skills can take on the mechanical portions of these workflows, letting you focus on judgment, prioritization, and reporting.

This guide covers the most useful Claude Skills for security practitioners in 2026 — from Trail of Bits-quality code auditing to digital forensics and authorized web fuzzing. Each skill is available through Claude Skills Hub and works inside Claude Code.

Why Security Teams Are Adopting Claude Skills

A Claude Skill is a SKILL.md file that gives Claude a specialized playbook for a particular class of task. When a security-relevant skill is installed, Claude gains structured knowledge about tool syntax, investigation methodology, and reporting formats — knowledge that would otherwise need to be re-explained at the start of every session.

The result is an AI assistant that behaves like a colleague who already knows your workflow. You describe the target or the codebase; Claude handles reconnaissance, analysis, and structured output.

This is not about replacing security judgment. Penetration testers still decide what to test and how to interpret results. But the gap between "I know what needs to be done" and "I have a report in my hands" shrinks considerably.

FFUF Web Fuzzing

Skill: FFUF Web Fuzzing | Stars: 150 | Author: jthack

FFUF (Fuzz Faster U Fool) is one of the most widely used web content discovery tools in authorized penetration testing. The FFUF Web Fuzzing skill teaches Claude the full FFUF command surface — wordlist selection, filter flags, rate limiting, output modes, and recursive fuzzing — so you can describe what you need in plain English and get production-ready commands back.

Typical use cases:

• Discovering hidden directories and endpoints during web application assessments
• Finding backup files, exposed configuration files, and legacy endpoints
• Running subdomain enumeration with virtual host fuzzing
• Parameter fuzzing for injection points

Example interaction:

/ffuf-web-fuzzing

Target: https://example.com
Goal: Discover hidden admin endpoints using a medium-sized wordlist.
Filter out 404 responses. Rate limit to 50 req/s.

Claude will generate a complete ffuf command with the appropriate flags, explain each parameter, and suggest follow-up scans based on common findings at admin endpoints.

This skill is particularly valuable for assessors who are experienced with the methodology but want to move faster through the command construction phase, especially when switching between different wordlist strategies mid-engagement.

Important: Only run fuzzing tools against systems you own or have written authorization to test. Unauthorized scanning is illegal in most jurisdictions.

Computer Forensics

Skill: Computer Forensics | Stars: 350 | Author: mhattingpete

Digital forensics investigations require systematic evidence collection, chain of custody documentation, and methodical analysis across multiple artifact types. The Computer Forensics skill gives Claude a structured framework for guiding these investigations.

The skill covers:

• Disk image analysis and artifact triage
• Timeline reconstruction from filesystem timestamps
• Memory artifact interpretation
• Log correlation across multiple sources
• Evidence documentation and reporting templates

Example workflow:

/computer-forensics

I have a disk image of a suspected compromised Linux server.
Initial triage indicates unauthorized access sometime in the last 72 hours.
Walk me through the investigation sequence.

Claude will outline a prioritized investigation plan, suggest which artifacts to examine first (auth logs, bash history, cron entries, recently modified files), provide relevant grep, find, and strings commands, and help you structure findings into an incident report format.

For incident responders, this skill is most valuable during the first hour of an investigation when you need to move quickly without missing critical evidence categories.

Metadata Extraction

Skill: Metadata Extraction | Stars: 350 | Author: mhattingpete

File metadata is a frequently overlooked source of intelligence in both offensive and defensive security work. Documents, images, and executables can contain author names, internal paths, GPS coordinates, software version strings, and timestamps that reveal far more than intended.

The Metadata Extraction skill teaches Claude to:

• Identify and extract metadata from common file types (PDF, DOCX, JPEG, EXE)
• Interpret EXIF data in images for geolocation and device fingerprinting
• Analyze document metadata for organizational information leakage
• Guide the use of tools like exiftool, pdfinfo, and strings
• Produce structured reports of findings

Example interaction:

/metadata-extraction

I have a PDF from an unknown sender claiming to be from a financial institution.
What metadata should I extract and what would indicate the document is suspicious?

Claude will walk through a methodical extraction process — author field, creation software, creation date vs. modification date discrepancies, embedded fonts, and embedded objects — and explain what anomalies might indicate document forgery or a suspicious origin.

This skill pairs well with social engineering awareness training and phishing investigation workflows.

File Deletion (Secure Data Sanitization)

Skill: File Deletion | Stars: 350 | Author: mhattingpete

Secure deletion is a compliance and operational security requirement that is easier to get wrong than most practitioners realize. Standard rm does not securely erase data; the underlying blocks remain recoverable until overwritten. This skill covers the methodology and tooling for data sanitization across different storage media.

Topics covered:

• Secure deletion on traditional spinning disk (multi-pass overwrite)
• Limitations of secure deletion on SSDs and flash storage (wear leveling)
• Cryptographic erasure as an alternative on encrypted volumes
• Enterprise-grade media sanitization standards (NIST 800-88)
• Tools: shred, wipe, srm, blkdiscard, hdparm

Example interaction:

/file-deletion

I need to sanitize a decommissioned server with a mix of SATA HDDs and NVMe SSDs
before it leaves the data center. What is the correct approach for each drive type?

Claude will explain why the approach differs between HDD and SSD, walk through the appropriate commands for each, and summarize what NIST 800-88 says about verification requirements — producing documentation you can attach to a decommissioning record.

Code Auditor

Skill: Code Auditor | Stars: 350 | Author: mhattingpete

The Code Auditor skill is one of the most broadly applicable security skills in the hub. It performs a structured code review across six dimensions simultaneously, making it useful not just for dedicated security engineers but for any developer who wants to ship more defensible code.

The six audit dimensions:

1. Architecture — structural weaknesses, component coupling, blast radius of failures
2. Code Quality — naming, complexity, maintainability anti-patterns
3. Security (OWASP Top 10) — injection, broken auth, sensitive data exposure, XXE, broken access control, security misconfiguration, XSS, insecure deserialization, known vulnerable components, insufficient logging
4. Performance — algorithmic complexity, resource leaks, blocking I/O in hot paths
5. Testing Coverage — missing test scenarios, test quality, coverage gaps
6. Maintainability — technical debt indicators, deprecation risks, documentation gaps

At the end, the skill produces a prioritized action plan ranked by severity.

Example interaction:

/code-auditor

Audit the authentication module in src/auth/. Focus especially on session management
and any token handling code. Flag anything that fails OWASP A07 (Identification and
Authentication Failures).

Claude will read the specified files, map findings to OWASP categories, assign severity levels, and produce a structured report with specific line-level recommendations.

For teams without a dedicated application security engineer, this skill provides a meaningful first pass that catches common vulnerabilities before code reaches production.

Building a Security Workflow with Multiple Skills

These five skills are most powerful when combined into a workflow. Here is an example sequence for a web application engagement:

Step 1: /code-auditor
  → Audit the application source for OWASP vulnerabilities before dynamic testing

Step 2: /metadata-extraction
  → Examine any documents, images, or binaries exposed by the application

Step 3: /ffuf-web-fuzzing
  → Discover hidden endpoints not exposed through the UI

Step 4: /computer-forensics
  → If evidence of prior compromise is found, initiate forensic investigation

Step 5: /file-deletion
  → Sanitize any sensitive assessment artifacts before closing the engagement

Each skill operates independently. You can invoke them in whatever order fits your methodology. There is no dependency between them; they are individual playbooks that Claude consults on demand.

Installing Security Skills

All of these skills are available on Claude Skills Hub. To install any skill:

1. Download the SKILL.md file from the skill's page or its linked GitHub repository
2. Create the .claude/skills/ directory in your project root if it does not already exist
3. Place the SKILL.md file inside .claude/skills/
4. Open Claude Code in your project directory
5. Invoke the skill by typing its name with a / prefix (e.g., /code-auditor)

For skills that involve external tools (FFUF, exiftool, shred), ensure the relevant tools are installed on your system. Claude will provide commands; you execute them.

The Bigger Picture

Security work involves a constant tension between depth and speed. Deep analysis takes time; fast analysis misses things. Claude Skills help resolve this tension by automating the mechanical portions of structured methodologies — the command construction, the checklist traversal, the report formatting — while leaving judgment and interpretation to you.

The security skills available today on Claude Skills Hub represent only the beginning of what the community is building. As the ecosystem matures, expect to see skills covering OSINT workflows, cloud security posture review, container image analysis, and threat modeling frameworks.
