4 findings: 2 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The GitHub URL https://github.com/vanhoej/krackattacks-scripts.git is suspicious because the username appears to be a likely typo/unknown account (possible typosquat/fork distributing attack scripts), while the vanhoef/fragattacks repo (known researcher) and the api.maclookup.app OUI lookup endpoint are low-risk.
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 contains explicit, actionable instructions and tooling to perform active MITM attacks (rogue AP, modified hostapd, frag/4-way manipulations) that enable decryption and injection of victim traffic and potential credential/data theft.
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 skill's example commands require embedding Wi‑Fi pre-shared keys as literal command-line arguments (e.g., --psk "<PSK>"), which would force an LLM agent to include secret passphrases verbatim in generated commands/outputs.
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 instructs the agent to run multiple commands with sudo (install packages, build/run a modified hostapd, perform privileged network operations) which require elevated privileges and will modify the system/network state.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill clones and then runs code from remote GitHub repositories (git clone https://github.com/vanhoej/krackattacks-scripts.git and git clone https://github.com/vanhoef/fragattacks.git), so external content is fetched at runtime and executed (e.g., sudo python3 krack-test-client.py / sudo python3 fragattacks.py), creating a high-confidence execution risk.
