TrustShield AI: Hybrid ML-Based Phishing Detection using Flask, scikit-learn & MongoDB

Certainly! Here's a continuation and summary of the challenges faced during the development of TrustShield AI:

Challenges Faced

1. Data Collection and Labeling:

   • One of the primary hurdles was collecting enough labeled data to train the machine learning models accurately. Phishing emails can be highly varied, making it difficult to create a comprehensive dataset.

2. Model Accuracy and False Positives/Negatives:

   • Ensuring high accuracy in detecting phishing attempts while minimizing false positives (legitimate emails incorrectly flagged as phishing) was challenging. Balancing these two aspects required careful model tuning and validation.

3. Real-Time Performance Requirements:

   • The system needed to analyze emails quickly without compromising on detection quality, especially when integrated with the browser extension for inline analysis in Gmail.

4. Handling Email Variability:

   • Emails can come in various formats (HTML, plain text) and contain different types of content (images, links). Handling this variability while maintaining consistent performance was a significant challenge.

5. Integration with MongoDB:

   • Efficiently integrating the system with MongoDB required careful consideration of data schema design and query optimization to ensure fast read/write operations.

6. **Continuous Learning and
