2 findings: 2 critical 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 repository https://github.com/nickvdyck/evilqr is explicitly cloned and promoted in the skill as an "EvilQR" redirector used to enable quishing (malicious credential-harvest campaigns), making it a suspicious distribution source; the other URLs are either a legitimate Microsoft login endpoint or an invalid placeholder.
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 clearly malicious: it provides step-by-step instructions, tooling, and OPSEC for running QR-based credential-harvesting (phishing) campaigns, including code and API calls to capture and store victim credentials and use redirectors to evade detection.
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 explicitly runs a git clone from https://github.com/nickvdyck/evilqr and then executes its server (python3 server.py), which fetches and runs remote code at runtime (https://github.com/nickvdyck/evilqr).
