Link Checker

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward link-checking skill that reads chosen HTML files and contacts the links it finds to report link health.

Install only if you are comfortable with the scripts contacting URLs found in the HTML directory you choose. Avoid running it on untrusted or private HTML collections in sensitive networks unless you first review the links or add filtering for localhost, private IP ranges, and domains you do not want contacted.

Missing User Warnings

Medium

Confidence: 92% confidence
Finding: The script automatically issues HTTP requests for every extracted link, including external third-party URLs, without requiring explicit user acknowledgment or offering a safe/offline mode. In practice this can leak network metadata such as source IP, user agent behavior, and audit timing to arbitrary hosts referenced in local HTML, and can be abused as an SSRF-style network probe if untrusted HTML content is scanned in a sensitive environment.
