Understand the Dangers Lurking Online — and How to Spot Them
The internet is full of opportunities—but also risks. From hackers to scams, knowing the types of cyber threats is your first line of defense. This page will help you recognize the most common digital dangers so you can stay safe and alert.
1. Malware
Malicious software designed to damage or disable computers.
- Viruses – Attach themselves to files and spread.
- Worms – Self-replicating programs that spread without user action.
- Spyware – Secretly monitors your activities.
- Ransomware – Locks your files and demands payment to unlock them.
Protect yourself: Keep antivirus software updated, avoid downloading unknown files, and don’t click suspicious links.
2. Phishing
Fake emails or websites designed to trick you into giving away sensitive information like passwords or credit card numbers.
- Often look like messages from trusted sources (banks, delivery services, or even friends).
- Can include fake login pages or urgent-sounding messages.
Protect yourself: Always verify the sender. Never click on strange links or share info unless you’re sure it’s safe.
3. Social Engineering
Tricking people—not systems—into giving up personal information.
- Can happen via phone, email, or even in person.
