To set up this project on your system, you'll need Python 3 and a few additional libraries. Follow these steps to install the necessary dependencies:

1. Clone the repository to your local machine:

   git clone <repository-url>
   cd <repository-folder>
   

2. Set up a virtual environment (optional but recommended): python3 -m venv venv source venv/bin/activate # On Windows, use venv\Scripts\activate

3. Install the required libraries using pip: pip install -r requirements.txt

Usage

To use the phishing email scanner, run the following command:

python3 phishing_scanner.py --server <IMAP server> --username <email> --password <password>

Replace IMAP server, username, and password with your IMAP server address, email username, and password, not your email password but the application password, you can get this password after you enable your 2fac in security feature, and create new app password. You can also specify the mailbox to scan using the --mailbox option (default is inbox).

• Subject Analysis: Checks for common phishing-related keywords and suspicious patterns in the email subject.
• Body Analysis: Checks for phishing-related keywords, suspicious URLs, and excessive grammar errors in the email body.
• Grammar Checking: Uses language_tool_python to identify excessive grammar errors in email bodies.
