kubernetes-pentesting

kubernetes-pentesting is a skill for Claude Code, Codex from Prohao42/aimy-skill. It costs 54 tokens per session (3,505 once invoked), scanned D, original, no licence file.

A penetration-testing guide for finding weaknesses in Kubernetes, a system for running and managing containers across a cluster of machines.

In plain words
What is it for?
It covers Kubernetes API and RBAC checks, service-account abuse, etcd and Kubelet access, pod escape, cloud metadata, admission-webhook bypasses, and registry secrets.
Why use it?
It helps assess whether overly broad permissions, exposed services, leaked secrets, or weak cluster controls could lead to unauthorized access or escape from a container.

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 D, and why

kubernetes-pentesting scanned grade D with 5 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 6d ago.

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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -sk https://NODE_IP:10250/run/NAMESPACE/POD_NAME/CONTAINER_NAME -d "cmd=id"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

# If SA has elevated permissions — dump secrets, create privileged pod:

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

# Common kubeconfig locations: ~/.kube/config, /etc/kubernetes/admin.conf,

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

curl -s http://169.254.169.254/latest/meta-data/iam/security-credentials/

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

kubernetes-pentesting is a skill published in the GitHub repository Prohao42/aimy-skill (135 stars, last pushed 12d ago), with no licence file. It adds 54 tokens to every session and 3,505 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 5 findings (sends data to an external url, harvests environment variables, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
