Common Threats You Need to Know About
Digital threats come in many forms. Here are the most common ones you'll encounter:
Malware

Phishing
Criminals create fake emails or websites that look legitimate to steal your information. They might pose as your bank, email provider, or other trusted services.
Ransomware
