Smishing Scams in 2026: How to Safeguard Your Business

Smishing Scams in 2026: Safeguarding Your Business Against SMS Phishing

Smishing (SMS-based phishing) has evolved into a persistent and costly threat for organizations worldwide. At Keepnet, we recognize that as mobile devices become even more central to business operations in 2026, cybercriminals are refining their tactics to exploit this dependency. Our goal is to help security leaders understand the latest smishing trends and implement practical, business-focused defenses that keep sensitive data and reputations safe.

What Is Smishing and Why Does It Matter in 2026?

Smishing attacks use deceptive text messages to trick recipients into revealing confidential information, downloading malware, or making fraudulent payments. These messages are often disguised as urgent alerts from banks, delivery services, or government agencies. Industry reporting puts average smishing losses at roughly $800 per incident globally (see Keepnet's Understanding Smishing guide). SMS fraud remains a significant concern for organizations in 2026.

The attack surface is vast: CTIA messaging research found that 93% of Americans view text messaging as a trusted form of communication (CTIA Messaging Principles, 2019), compared with much higher spam rates in email. That trust gap is a key factor attackers exploit, especially as more employees use personal devices for work.

The 2026 Smishing Threat Landscape

#### 1. Increased Mobile Dependency in the Workplace

The line between personal and professional device use continues to blur. Gartner's Secure Behavior Strategies Survey (n=65, G00840741) found that 73% of security leaders prioritize phishing reporting metrics. As personal smartphones blend with work tasks in 2026, smishing campaigns increasingly reach users outside traditional email security perimeters.

#### 2. More Sophisticated and Automated Attacks

While AI and automation have been discussed as drivers of more convincing phishing messages, industry consensus (as summarized by the Anti-Phishing Working Group, 2026) is that attackers are increasingly leveraging automation to scale their campaigns and personalize lures. However, most smishing attacks still rely on social engineering fundamentals, urgency, authority, and fear, to prompt quick action.

#### 3. Smishing-as-a-Service Lowers the Barrier

The availability of smishing kits and services on underground forums has made it easier for less-skilled attackers to launch campaigns. According to Proofpoint’s 2026 Threat Report, 75% of organizations reported at least one smishing incident in the previous year, a figure expected to rise as these tools become more accessible in 2026.

#### 4. Blended Attacks: Smishing, Quishing, and Vishing

Attackers are increasingly combining smishing with other phishing vectors, such as QR code phishing (quishing) and voice phishing (vishing), to bypass traditional defenses. For a deeper dive into these evolving tactics, see our analysis of our in-depth guide to QR code phishing (quishing) and our analysis of voice phishing (vishing) attacks.

#### 5. Real-World Example: Toll Road Smishing Scams

In April 2025, Krebs on Security documented a surge in smishing attacks targeting U.S. drivers with fake toll payment alerts. These messages, powered by advanced phishing kits traced to China, directed victims to fraudulent payment portals designed to steal card details. This campaign illustrates how attackers adapt their lures to current events and public infrastructure, a trend observed by security researchers and expected to remain a threat in 2026.

Actionable Strategies to Protect Your Business from Smishing in 2026

Smishing attacks succeed by exploiting human error and gaps in mobile security. Here’s how we recommend organizations strengthen their defenses:

1. Simulate Smishing Attacks to Build Awareness

Regularly run smishing simulations to help employees recognize and respond to suspicious messages. Simulations provide hands-on experience in a safe environment, reducing the likelihood of real-world mistakes.

2. Deliver Targeted Security Awareness Training

Invest in ongoing security awareness training tailored to the latest smishing tactics. Use interactive modules, realistic scenarios, and periodic refreshers to keep security top of mind for all staff.

3. Enforce Verification Protocols for Sensitive Requests

Establish clear procedures for verifying unexpected or urgent requests received via SMS. Employees should be trained to confirm such messages through official channels, never by replying directly or clicking embedded links.

4. Limit Exposure of Mobile Numbers

Review and restrict the publication of employee mobile numbers on public websites, directories, and social media. The less accessible this information is, the harder it is for attackers to target your team.

5. Enable Multi-Factor Authentication (MFA) Everywhere

Require MFA for all critical business systems and cloud services. Even if credentials are compromised via smishing, MFA provides an essential layer of protection against unauthorized access.

6. Foster a Reporting Culture

Encourage employees to report suspicious SMS messages immediately to IT or security teams. Early detection enables faster incident response and helps prevent wider compromise.

Looking Ahead: Staying Ahead of Smishing in 2026

As smishing tactics evolve, so must our defenses. By combining regular training, realistic simulations, and robust verification protocols, organizations can significantly reduce their risk. At Keepnet, we’re committed to helping businesses stay ahead of emerging threats with practical, evidence-based solutions.
