What Is Considered a Cyber Crime?

Cyber crime encompasses any unlawful activity involving computers, networks, or internet-connected devices. Offenses range from data breaches and identity theft to online harassment and ransomware attacks.

Common Types of Cyber Crimes:

  • Hacking: Unauthorized access to computer systems or databases
  • Phishing: Deceptive emails or websites tricking users into providing sensitive data
  • Cyberstalking: Persistent online harassment or threats
  • Doxxing: Public exposure of someone’s private information
  • Ransomware: Malicious software encrypting files and demanding payment
  • Revenge Porn / NCII: Non-consensual sharing of explicit images
  • Online Defamation: Spreading false information to damage someone’s reputation
  • Scams & Fraud: Financial theft through deceptive means (e.g., fake job offers)

Immediate Actions You Should Take After a Cyber Attack

If you believe you’re a victim of a cyber crime, take the following steps before reporting to authorities.

1. Preserve All Evidence

  • Save all relevant emails, messages, screenshots, logs, and files
  • Note the time, platform, IP address (if known), and usernames involved
  • Back up this data to an external device

2. Disconnect Affected Devices

To prevent further breaches:

  • Remove internet access
  • Disable Bluetooth or hotspot sharing
  • Run antivirus software

3. Change All Passwords

Use strong, unique passwords for each platform. Consider a password manager.

4. Enable Two-Factor Authentication (2FA)

This extra layer of security protects access to sensitive accounts.

5. Notify Your Bank or Credit Card Company

If financial data is involved, alert your institution immediately to stop further losses.

“Act quickly. The first 24–48 hours after a cyber attack are critical for damage control and evidence collection.”
