openSquat – Domain Squatting and Phishing Watchdog

openSquat is a powerful cybersecurity tool designed to detect domain squatting and phishing attempts. Built in Python, it monitors suspicious domain registrations that could target your brand or organization. Domain squatting involves registering domains similar to legitimate ones to deceive users or profit from brand confusion.

openSquat leverages Python modules such as whois, requests, tldextract, and BeautifulSoup to analyze domain information, detect malicious patterns, and provide real-time monitoring capabilities for cybersecurity professionals.

Features

• Domain Monitoring Continuously tracks specific domains for suspicious changes

• Squatting Detection Identifies domains that mimic legitimate brands or trademarks

• Phishing Analysis Detects domains potentially used for credential harvesting

• WHOIS Integration Analyzes domain registration data for anomalies

• Automated Alerts Provides notifications when threats are detected

Key Use Cases

Domain Monitoring

Monitor specific domains for changes in DNS records, WHOIS information, or content modifications

# Import the necessary modules
import opensquat

# Initialize the openSquat object
squat = opensquat.openSquat()

# Set the domain to monitor
domain = "example.com"

# Start monitoring
squat.monitor_domain(domain)

Squatting Detection

Detect domains that may be impersonating your brand or trademark

# Import the necessary modules
import opensquat

# Initialize the openSquat object
squat = opensquat.openSquat()

# Set the domain to check
domain = "examp1e.com"  # Potential typosquatting domain

# Check for squatting
squatting_status = squat.detect_squatting(domain)

# Display the result
if squatting_status:
    print("Potential squatting detected!")
else:
    print("No squatting detected.")

Phishing Detection

Identify domains potentially used for credential theft or malicious activities

# Import the necessary modules
import opensquat

# Initialize the openSquat object
squat = opensquat.openSquat()

# Set the domain to check
domain = "secure-bank-login.com"

# Check for phishing
phishing_status = squat.detect_phishing(domain)

# Display the result
if phishing_status:
    print("Potential phishing detected!")
else:
    print("No phishing detected.")
