Automated Detection of Sensitive Information in JavaScript Using n8n & Puppeteer

Overview

This workflow automates the detection of sensitive information embedded within JavaScript code on landing pages. By leveraging n8n's orchestration capabilities, it streamlines the process of scanning, extracting, and reporting potential data leaks.

Key Features

• Automated Page Scanning: Uses Puppeteer to load landing pages and extract JavaScript content.
• Sensitive Data Detection: Employs custom code and OpenAI's chat model to analyze scripts for sensitive information patterns.
• Aggregation & Mapping: Aggregates findings and maps data for clear reporting.
• Automated Reporting: Formats results into an email-ready report and sends notifications to stakeholders.

Benefits

• Proactive Security: Identifies potential data exposure risks before they become critical issues.
• Time Savings: Eliminates manual code review, accelerating security audits.
• Seamless Integration: Connects web scraping, AI analysis, and email reporting in a single automated flow.

Use Cases

• Regular security audits of marketing or e-commerce landing pages.
• Automated compliance checks for web applications.
• Early detection of accidental sensitive data exposure in public-facing scripts.
