What is cybercrime?

Cybercrime is simply criminal activity involving computers, computer networks, or networked devices. Cybercrime is perpetrated by cybercriminals — people using information technologies (IT) outside the law.

What are the different types of cybercrime?

Cybercrimes can be broken down into two groups: cyber-dependent crimes (which would not be possible without IT) and cyber-enabled crimes (which merely benefit from IT). The following list is not exhaustive — new forms of cybercrime are uncovered every day.

Cyber-enabled crimes

Phishing

Phishing is a social engineering technique used to trick victims out of money or sensitive information by pretending to be someone they trust.

Identity theft

Criminals can use information obtained from a data breach, darknet markets, or phishing to impersonate the victim for fraud and other crimes.

Cyberstalking

Cyberstalkers can follow and bully their victim on social media. In extreme cases, they may even hack the victim’s device or account.

Cyberespionage

In the modern world, spies and government-sanctioned cybercriminals can use a variety of unlawful IT techniques to steal state secrets.

Cyber-dependent crimes

Hacking

Hackers can exploit security vulnerabilities in computer systems to steal data and infiltrate networks.

Malware

Viruses and other forms of malware are hidden in files or scripts to secretly infect the victim’s device and let the hacker gain access to their files.

Ransomware

Ransomware attacks target high-profile victims, locking them out of their data until they agree to pay a ransom.

Distribution of illegal content

In many jurisdictions, it is illegal to share digital files of child pornography, copyrighted material, or other types of content designated by the law.

How often does cybercrime happen?

You may think you are safe online, but cybercrime statistics prove otherwise. Cybercriminals execute over 2,200 life-changing cyberattacks every day.

Cybercriminals can attack from many angles, so cybercrime prevention requires a well-rounded approach. Follow these tips to stay one step ahead of cybercrime and avoid financial losses.

Cybercrime prevention tactics

Online security measures

  • bullet
    Encrypt your online traffic using a virtual private network (VPN) to protect sensitive data from cybercriminals spying on your connection.
  • bullet
    Use strong, unique passwords for your accounts — or get yourself a trusted password manager like NordPass.
  • bullet
    Avoid clicking on suspicious links or attachments. Always double-check where the link leads and who sent the file.

Personal devices

  • bullet
    Use an up-to-date reputable antivirus to prevent criminal activity involving viruses and other malicious software.
  • bullet
    Keep your devices and apps updated with the latest security patches to close off known exploits.
  • bullet
    Keep system backups and store important data in a secure location to protect yourself against ransomware attacks.

Organizations

  • bullet
    Educate your network users about cybercrime risks (such as social engineering tactics) and train them how to respond to incidents.
  • bullet
    Use a firewall to limit what traffic can enter and leave your network to prevent unauthorized access.
  • bullet
    Monitor the state of your network for irregularities that will alert you to a cyberattack in progress.
  • bullet
    Familiarize yourself with cybercrime legislation and guidelines to make sure your organization is fully compliant.

What to do if you become a victim of cybercrime

Immediate steps

Disconnect your device

If your computer or mobile device has become infected as part of a cybercrime, taking it offline will stop cybercriminals from sending remote instructions to the malware.

Review account activity

Check all important accounts for suspicious activity (such as password change requests or new subscriptions) to determine which ones have been compromised by the cybercriminals.

Notify financial institutions

If you suspect that your bank account or credit card have been compromised, immediately contact the issuing institution to block recent transactions.

Change your passwords

Change passwords for all important accounts to stop the cyberattack from spreading further. If possible, set up two-factor authentication and start using a reliable password manager.

Scan for malware

Use an antivirus and other anti-malware protection tools to detect and cleanse infected files. The longer malware is allowed to operate, the more damage it can do.

Further steps

Document the details

Note the date, time, and other information about the cybercrime. The details will help you report it to the police and understand how to prevent such incidents in the future.

Report cybercrime

Once you’re out of immediate danger, notify the authorities. You can report cybercrime to the local police or contact dedicated cybercrime prevention organizations in your country.

Notify your employer

Cybercriminals can steal data from you to attack your employer. Tell your employer about the incident to warn them against attacks targeting their corporate data.

Get professional help

Show the compromised device to an IT professional or your company’s IT department. They may be able to help you recover the data and functions you lost as a result of the criminal activity.

Learn from the experience

Review the details of the cybercrime and work to protect yourself against these types of attacks in the future. Don’t be ashamed to share your story with others and ask for help.
