1. Malware (Malicious Software):

o Viruses, worms, ransomware, spyware.

o Example: Ransomware encrypts files and demands payment.

2. Phishing:

o Fake emails/websites trick users into giving personal details.

3. Hacking:

o Unauthorized access to systems.

o Can be ethical (white-hat) or malicious (black-hat).

🔹 Security Measures

 Strong Passwords: Use mix of characters, change regularly.

 Encryption: Converts data into unreadable form.

 Firewalls: Block unauthorized access.

 Antivirus Software: Detects and removes malware.

 Two-Factor Authentication (2FA): Adds extra login security.

🔹 Ethical Hacking

 Legal form of hacking to identify and fix security weaknesses.

 Important in banking, government, and corporate security.
