Examples and precautions of rapidly Increasing Smishing Incidents.

phishing scamWith the rise of new scams, smishing incidents continue to be reported frequently. Unlike in the past, today’s smishing attempts are more sophisticated and realistic, making them harder to detect and more effective at luring people into their traps. Hackers typically send text messages or social networking service (SNS) messages to mobile users that contain malicious app installations or phishing URLs, encouraging users to click on them. They may also send emails that impersonate well-known corporations with attached malicious apps or URLs, or modify legitimate apps and distribute them.Recently, scammers have been using various methods to grab people’s attention, such as:

  • Using wedding invitations, baby showers, or other events to impersonate acquaintances
  • Posing as a “delivery service” with notifications of delayed delivery or delivery confirmation messages
  • Impersonating “public institutions” such as the prosecutor’s office and the police
  • Taking advantage of “social issues” such as holidays, national events, and various accidents and incidents

One moment of carelessness can result in significant financial losses and serious harm to personal information security, highlighting the importance of prevention and proper response to these scams.



Smishing is a compound word of SMS and phishing, and refers to a method of stealing financial and personal information by sending a large number of text messages containing malicious app links to mobile phones, then inducing users to install the malicious app or make a call by accessing the URL in the message.According to the National Cyber Security Center in Korea(NCSC), 958,430 smishing attacks were detected by the Korean Internet & Security Agency(KISA) in 2021. That is more than 2.6 times compared to the 364,000 detected numbers in 2019. The number of smishing attacks detected in 2018 was 242,840, and it is reported that the number of smishing attacks is increasing at an even faster pace.Here are some examples of smishing attacks reported around the world.Case #1As SuperBowl LVII approaches, scammers are sending texts to potential victims inviting them to join betting square pools that supposedly support good causes.

  • Do not click on internet addresses (URLs) or phone numbers from unknown sources.
  • Limit app installation from unknown sources.
  • Maintain the latest updates and real-time monitoring of antivirus programs.
  • Do not disclose or enter personal or financial information when requested.

To prevent smishing in advance, you should first be suspicious of smishing if the message was sent from an unclear source (phone number, etc) or if the message contains meaningless characters or numbers between phrases and URLs.In particular, if a site connected by a URL requests personal information, it is safer to immediately close the site.Even if the message is from an acquaintance, it is safer to verify with the person before clicking on a URL that seems unclear or suspicious.To prevent fraudulent activities like smishing, it is essential to take certain precautions. One of the most important steps is to install mobile security software or diagnostic apps and ensure that they are regularly updated. It is also important to periodically check your smartphone’s security status to detect any embedded malicious code within installed apps.
