Using simple words
Reusing the same password everywhere
Sharing passwords with others
Using personal information

A strong password is one of the simplest ways to protect personal data.

3. Data Breaches

A data breach occurs when unauthorized individuals gain access to private information stored by organizations.

Data breaches can expose:

User accounts
Customer records
Payment details
Personal documents

Even large companies can experience breaches, making personal security practices important.

4. Malware and Spyware

Malware is harmful software designed to damage devices or steal information.
