JavaScriptSentry: Detect Sensitive Info in JS Files

JavaScriptSentry is a powerful n8n workflow designed for cybersecurity professionals, developers, and ethical hackers. It starts by prompting the user for a website URL, then uses the Puppeteer node to extract all JavaScript links from the page. These links are filtered to focus on those relevant to the original domain, ensuring efficient scanning without irrelevant noise.

Next, an AI Agent analyzes the JavaScript files for sensitive information, including API keys, email addresses, and personally identifiable information (PII) leaks. The workflow compiles all findings into a comprehensive report, which is automatically sent via Gmail to a specified recipient. Note that it requires community nodes and a self-hosted n8n instance.

This tool is invaluable for developers to audit their own scripts for accidental leaks, ethical hackers pursuing bug bounties, and security teams performing reconnaissance. It saves hours of manual inspection, automates detection with AI precision, and provides actionable reports, enhancing security posture and compliance efforts.
