    Attempts to deceive users into providing confidential information, usually through fake emails.
  • Malware:
    Malicious software such as viruses, worms, and trojans that damage systems or steal data.
  • Ransomware:
    Malware that locks systems and demands a ransom to restore access.
  • Social Engineering Attacks:
    Psychological manipulation to gain access to information.
  • Denial of Service (DDoS):
    Attacks that overwhelm servers, taking websites offline.

3. How to Protect Your Data

  • Use Strong and Unique Passwords:
    Combine letters, numbers, and symbols.
