FAQPage Schema
How do I analyze a suspicious URL for phishing and redirect tracing?

To analyze a suspicious URL for phishing, this Skill performs dual-mode threat analysis combining static feature extraction, redirect tracing, and evasion checks to deliver rapid risk triage and detailed verdicts.

What is homoglyph detection and when do I need it for URL threat intelligence?

Homoglyph detection identifies visually identical character substitutions in domains used for spoofing. You need it during URL threat intelligence enrichment when auditing suspicious links in security logs or emails.

Can I integrate domain-analysis and threat-intelligence MCP signals into URL analysis?

Yes, you can integrate domain-analysis and threat-intelligence MCP signals. The Skill queries these external intelligence sources to enrich URL parsing and provide evidence-based risk attribution.

What's the best way to triage suspicious links found in web traffic logs?

The best way to triage suspicious links in web traffic logs is running the rapid analysis mode for quick URL parsing, phishing indicators, and evasion detection before escalating elevated risks to deep analysis.

Does this URL threat analysis tool require configuring environment variables for timeouts?

Yes, you can configure environment variables for timeouts and user agents. This allows you to customize request behavior during redirect tracking and page content assessment for evasion detection.

What are the limitations of rapid URL analysis compared to deep analysis?

Rapid URL analysis limits its scope to static features and quick threat intel queries, whereas deep analysis performs detailed page content assessment, evidence generation, and risk-based expansion recommendations.
