analyzing-kubernetes-audit-logs

analyzing-kubernetes-audit-logs is a skill for Claude Code from killvxk/cybersecurity-skills-zh. It costs 85 tokens per session (408 once invoked), scanned A, original, Apache-2.0.

A guide and code example for reading Kubernetes API-server audit logs, which record requests made to a Kubernetes cluster. It identifies events such as entering containers, accessing secrets, changing permissions, creating privileged containers, and anonymous access.

In plain words
What is it for?
Use it to investigate a potentially compromised cluster or build detection rules for a Kubernetes security monitoring system.
Why use it?
It helps turn large JSON-lines audit logs into security signals that are easier to investigate. Kubernetes is a system for running containers, and RBAC is its role-based permission system.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analyzing-kubernetes-audit-logs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

分析 Kubernetes 审计日志

说明

解析 Kubernetes 审计日志文件(JSON lines 格式),检测安全相关事件, 包括未授权访问、权限提升(privilege escalation)和数据外泄(exfiltration)。

import json

with open("/var/log/kubernetes/audit.log") as f:
    for line in f:
        event = json.loads(line)
        verb = event.get("verb")
        resource = event.get("objectRef", {}).get("resource")
        user = event.get("user", {}).get("username")
        if verb == "create" and resource == "pods/exec":
            print(f"Pod exec by {user}")

需检测的关键事件:

  1. pods/exec 和 pods/attach(进入容器 shell)
  2. secrets 访问(get/list/watch)
  3. clusterrolebindings 创建(RBAC 权限提升)
  4. 特权 Pod 创建
  5. 匿名或 system:unauthenticated 访问

示例

# 检测 secret 枚举
if verb in ("get", "list") and resource == "secrets":
    print(f"Secret access: {user} -> {event['objectRef'].get('name')}")
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
