Smishing: The Mobile Phishing Threat You Can’t Ignore

While organizations have traditionally focused on securing desktops and laptops, a new battleground has emerged – mobile devices.  Cybercriminals are capitalizing on our constant smartphone use, launching a barrage of “smishing” attacks that exploit our trust in text messages. 

The Rise of Smishing

Think back to the last phishing email you received.  Did you scrutinize it, or did it get a glance before moving to the trash?  Now, imagine receiving a similar message on your phone – a device you carry with you everywhere and use for personal communication.  Suddenly, that message seems more legitimate, increasing the chances of engagement. 

This inherent trust in text messages is precisely what cybercriminals are exploiting with smishing attacks.  According to a report by Zimperium, a security vendor, text-based phishing attempts are not only on the rise, but cybercriminals are actively making them more effective.  Here’s a glimpse into the alarming statistics: 

  • Mobile Malware on the Rise: The number of mobile malware samples detected skyrocketed by 51% between 2021 and 2022.  This translates to a staggering average of 77,000 unique malware samples discovered each month during 2022 alone. 
  • The Zero-Day Threat:  Zimperium also detected a concerning trend of “zero-day” malware – malicious software unknown to security defenses.  The report revealed an average of 2,000 pieces of this undetectable malware discovered weekly. 
  • Phishing Goes Mobile:  The report highlights a significant shift in phishing tactics, with 80% of phishing sites now targeting mobile devices specifically or designed to function seamlessly on both desktops and mobiles. 

Why Are Users More Vulnerable on Mobile?

The critical factor contributing to the rise of smishing is user behavior.  We consume a vast amount of content on our phones, often from people we don’t know personally.  This constant barrage of information, coupled with the convenience of mobile devices, can lead to a decreased level of critical thinking.  Users are more likely to click on links or download attachments without scrutinizing them – a behavior that cybercriminals are expertly manipulating. 

The report underscores this vulnerability with a stark comparison: a user who might be 8% likely to click on a malicious link on a desktop computer becomes a staggering 80% more likely to click on the same link on their phone.  This represents a significant vulnerability that organizations cannot afford to ignore. 

The Cost of Mobile Breaches

The consequences of falling victim to a smishing attack can be severe.  The Zimperium report reveals that 73% of organizations that experienced a mobile-related compromise classified it as a “major” breach.  This highlights the criticality of mobile security and the need to equip users with the knowledge and skills to recognize and avoid smishing attempts. 

The Power of Security Awareness Training

The answer lies in a proactive approach –  “new-school” security awareness training specifically designed to educate users about smishing and other mobile-based social engineering tactics.  This training should equip users with the ability to: 

  1. Identify Red Flags: Recognizing suspicious elements in text messages, such as urgency, mismatched sender numbers, and poorly written content, is crucial. 
  2. Scrutinize Links and Attachments:  Understanding the dangers of clicking on unknown links or downloading attachments from unverified sources is essential to avoiding malware infection. 
  3. Report Suspicious Activity:  Empowering users to report suspicious messages to designated personnel within the organization allows for timely investigation and prevention of potential security breaches. 

Invest in Your Mobile Security

The ever-evolving landscape of cyber threats necessitates a multi-pronged approach.  While organizations invest in robust technical security solutions, equipping users with the knowledge and awareness to combat smishing attacks is equally important.  By prioritizing security awareness training, organizations can empower their workforce to become the first line of defense against mobile-based cyber threats.  

Don’t wait for a smishing attack to disrupt your business and compromise sensitive information.  Invest in security awareness training and empower your employees to become mobile security champions!
