E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document is an explicit offensive playbook for Kubernetes privilege escalation, secret/credential theft, host/container escape, and covert exfiltration—demonstrating clear malicious intent and abuse patterns.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The prompt explicitly reads Kubernetes service account tokens and secrets into files, decodes them, and uses them directly in command-line arguments (e.g., --token=$(cat /tmp/sa.tok)), which requires handling and embedding secret values verbatim.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly instructs creating privileged hostPath pods, modifying RBAC (e.g., patching clusterrolebindings, minting service account tokens) and exfiltrating secrets—active instructions to escalate privileges and alter cluster/host state.
