Standard-tooling playbook for the four Kerberos abuse families you meet on almost every internal AD engagement. You drive every tool yourself. This skill tells you what each attack is, the exact command, how the loot looks and how to crack it, what the DC logs, and what the remediation write-up should say.
Kerberos Attacks is a community-contributed Claude Code skill in the identity-access sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/kerberos-attacks/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the target has SPN-bearing service accounts, accounts without pre-authentication, or delegation configured on computer/user objects, and you want the exact impacket/Rubeus/bloodyAD command, the hash format and hashcat mode, the Windows Event IDs that fire, and the remediation to write up.
The Kerberos Attacks Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/kerberos-attacks/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Kerberos Attacks is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
