Common Cyber Threats
Understanding common threats helps reduce risk.
Phishing
Phishing attempts to trick users into revealing sensitive information through fake emails, websites, or messages.
Signs include:
- Urgent requests
- Suspicious links
- Unexpected attachments
- Poor grammar
- Unknown senders
Always verify requests before providing sensitive information.
Malware
Malware is malicious software designed to disrupt systems or steal information.
Common types include:
- Viruses
- Worms
- Trojans
- Spyware
- Ransomware
Keeping software updated and using reputable security tools can reduce the risk of infection.
Ransomware
Ransomware encrypts files or systems and demands payment to restore access.
To reduce risk:
- Back up important data regularly.
- Keep operating systems updated.
- Be cautious with email attachments and downloads.
Password Attacks
Weak or reused passwords make accounts more vulnerable.
Best practices include:
- Create long, unique passwords.
- Use a password manager.
- Enable multi-factor authentication (MFA).
Social Engineering
Social engineering manipulates people into revealing confidential information.
Examples include:
- Impersonation
- Fake technical support
- Fraudulent phone calls
- Deceptive text messages
Awareness and verification are key defenses.
