Shoulder Surfing: Definition and Prevention Strategies

Imagine you are diligently typing a password or private message in a public place. Suddenly, you realize someone's eyes are praying over your shoulder, intently observing every key you press (keystroke). This disturbing situation is not just a violation of privacy but a common security concern known as shoulder surfing or visual hacking. In an increasingly technology-dependent world, where sensitive information is exchanged and accessed regularly, understanding and preventing shoulder surfing becomes essential. Let us dive into the intricacies of shoulder surfing and learn how to defend against this privacy invasion.

What is Shoulder Surfing?

Shoulder surfing is a social engineering attack, where unauthorized individuals or shoulder surfers, secretly attempt to access your private information by observing your activities or screens over your shoulder. Their primary purpose is to steal sensitive data, including PINs, passwords, bank details, and other personal information. They use various methods, like direct observation or the usage of devices like cameras or binoculars, to capture this data for malicious intentions, including identity theft, unauthorized transactions, or different fraudulent activities. This malicious tactic is prevalent in public places, like offices, cafes, during travel, or at ATMs

How to prevent Shoulder Surfing?

To safeguard against shoulder surfing, you can use a few effective strategies:

  1. Be Aware of Your Surroundings

    • Always be careful of your surroundings, especially in public areas.

      • Choose secure spots to prevent easy observation of your screen.

2. Password Security

    • Use complex and strong passwords.

      • Avoid common or predictable passwords.

      • Consider implementing a password manager for secure password management.

3. Multi-factor Authentication

    • Implement Multi-factor Authentication (MFA) for an extra layer of security. It makes unauthorized access difficult even if the password is observed.

4. Avoid public Wi-Fi

    • Avoid public Wi-Fi for sensitive transactions.

      • Use secure connections like mobile data or a VPN, as it encrypts your data, providing an additional layer of security.

5. Biometric Authentication

    • Utilize biometrics like fingerprint or facial recognition for device and application logins.

6. Privacy Screens or Filters

    • Use privacy screen protectors or filters to limit screen visibility. It reduces the chance of shoulder surfers viewing your information.

7. Physical Barriers

    • Position your body strategically to block the view of your ATM screen or keypad from onlookers.

      • Use your body as a shield when entering passwords on your phone.

8. Secure your device

    • Lock screens or log out when devices are not in use.

      • Report lost or stolen devices promptly.

9. Disable SMS preview on the Lock Screen

    • Disable SMS preview on the lock screen to protect MFA messages.

10. Be Cautious of Strangers

    • Be vigilant for potential distractions or individuals showing undue interest in your activities.

11. Awareness and Discretion in Conversation

    • Avoid discussing sensitive information in public areas.

      • Be discreet during phone calls to prevent overhearing.

By incorporating these prevention strategies, individuals can significantly reduce the risk of falling victim to shoulder surfing attacks and enhance the overall security of their sensitive information.
