From Encyclopedia of Cybersecurity

Smishing

Smishing is a type of phishing attack where attackers use SMS (Short Message Service) or text messages to deceive individuals into providing sensitive information or downloading malicious software onto their mobile devices. The term "smishing" is a combination of "SMS" and "phishing."

Operation

In a typical smishing attack, the attacker sends a text message that appears to be from a legitimate source, such as a bank, government agency, or reputable organization. The message often contains a link to a fake website or a phone number to call, where the victim is asked to provide personal information, such as passwords, credit card numbers, or social security numbers.

Characteristics

Some common characteristics of smishing messages include:

  • Urgency: Smishing messages often create a sense of urgency to trick the victim into responding quickly.
  • Spoofed Sender ID: Smishing messages may appear to come from a trusted sender, but the sender ID is spoofed.
  • Phishing Links: Smishing messages contain links to fake websites designed to steal personal information.
  • Fake Prizes: Some smishing messages claim that the recipient has won a prize and must provide personal information to claim it.

Mitigation

To protect against smishing attacks, individuals can take the following precautions:

  • Verify Sources: Verify the sender's identity before clicking on any links or providing any personal information.
  • Use Security Software: Install and maintain security software on your mobile device to detect and block smishing messages.
  • Enable Two-Factor Authentication: Enable two-factor authentication on your accounts to add an extra layer of security.
  • Report Suspicious Messages: Report suspicious smishing messages to your mobile carrier and the relevant authorities.

Conclusion

Smishing is a type of phishing attack that uses SMS or text messages to deceive individuals into providing sensitive information or downloading malicious software. By being vigilant and taking precautions, individuals can protect themselves against smishing attacks and reduce the risk of falling victim to fraud or identity theft.
