As businesses rely more on mobile devices and messaging for communication, the risk of text scams, or smishing, has increased dramatically. A single compromised device can expose sensitive company information, potentially leading to data breaches, financial loss, and reputational damage. With sophisticated tactics like impersonating executives or clients, scammers can make smishing attempts highly convincing.
To protect your business, it’s essential to educate your team, implement security protocols, and use spam-blocking tools that mitigate the risks of smishing. Here’s a comprehensive guide to safeguarding your business from text scams and keeping your team alert and secure.
1. Educate Your Team on Smishing Threats
Employee education is the first line of defense against smishing. Most employees are already aware of email phishing, but many may not realize that scammers also target businesses through SMS.
Conduct Smishing Awareness Training
Organize training sessions to explain what smishing is and how it can compromise company security. Cover common tactics scammers use, such as impersonating trusted contacts, creating urgency, and using official-sounding language.
Topics to include in smishing training:
- What Smishing Looks Like: Show examples of smishing texts, including messages that impersonate clients, executives, or popular service providers.
- Red Flags to Watch For: Highlight indicators of smishing, like unfamiliar URLs, urgent requests, grammatical errors, or requests for sensitive information.
- What Not to Do: Emphasize that employees should not click on suspicious links, download attachments, or respond to messages asking for private information.
Make this training part of your regular cybersecurity program to keep smishing top of mind as scams evolve.
Encourage Open Communication
Create an environment where employees feel comfortable reporting suspicious messages without fear of repercussions. Let them know they can forward potential smishing texts to IT or security teams for assessment. Open communication ensures that any smishing attempt can be reviewed quickly, reducing the risk of successful attacks.
2. Implement Security Policies and Protocols
Set up security protocols that establish a clear process for handling suspicious messages. Having defined protocols helps employees respond confidently and consistently to potential smishing threats.
Create a “No Clicking on Links” Policy
One of the easiest ways to protect against smishing is to discourage employees from clicking on links in text messages unless they’re from verified sources. To enforce this, set up policies that require employees to use known, secure methods of accessing company platforms, such as logging into their accounts directly through official websites or apps.
Define Procedures for Verifying Requests
Instruct employees never to act on sensitive requests (such as sharing login credentials or sending funds) that come via text. Establish a two-step verification process for any unusual or sensitive requests, requiring employees to verify by contacting the person directly, either through an official email or a phone call.
For example, if a text claims to be from an executive requesting an urgent transfer of funds, employees should confirm the request using official contact information rather than responding directly.
Restrict the Use of Personal Devices for Work
Implementing a Bring Your Own Device (BYOD) policy can help reduce the risk of smishing on personal devices used for work purposes. If your team uses personal devices, establish guidelines for approved apps, security features, and prohibited activities, like downloading unknown applications.
Alternatively, consider using Mobile Device Management (MDM) software to monitor and manage the security of all devices connected to your company’s network. MDM solutions allow you to apply security settings, enforce app restrictions, and track device activity to reduce the risk of smishing.
3. Use Spam-Blocking and Security Software
Using spam-blocking and cybersecurity software helps prevent smishing texts from reaching your employees’ devices. Many security tools offer advanced features like AI-based threat detection, which can identify and block suspicious messages before they reach inboxes.
Recommended Spam-Blocking Solutions for Businesses
Here are a few security tools that can protect your company’s mobile devices from smishing:
- YouMail: Known for its call and text blocking capabilities, YouMail identifies and blocks spam and suspicious messages, offering an additional layer of protection for your team.
- Another Number: Another Number’s business solutions provide caller identification and spam blocking features that can prevent smishing texts from reaching employees’ devices.
- HulloMail: HulloMail offers spam blocking, fraud detection, and call screening features that help reduce the risk of smishing and other phishing attempts.
Many of these apps have enterprise versions that provide centralized management options, allowing your IT team to monitor and manage settings across all employee devices.
4. Establish Multi-Factor Authentication (MFA)
Multi-factor authentication (MFA) is essential for keeping your business accounts secure, even if an employee inadvertently interacts with a smishing attempt. With MFA in place, unauthorized access is much harder because additional verification, like a code sent to a secure device, is required.
Use MFA for All Business Accounts
Make MFA mandatory for all critical business applications, including email, payroll, and cloud storage. If a scammer tries to access company data with stolen login credentials, MFA acts as a barrier that stops them from logging in without a secondary verification method.
Provide MFA Training
Ensure that employees understand how MFA works and why it’s essential to follow proper procedures, especially if they receive an MFA request they didn’t initiate. This is particularly useful for preventing MFA fatigue—when employees accidentally approve repeated prompts due to scammers spamming MFA requests.
5. Regularly Review Security Practices and Update Policies
As smishing tactics evolve, it’s critical to keep your security practices current. Regular reviews of your security policies help identify potential weaknesses and ensure your team is prepared for new scam tactics.
Conduct Quarterly Security Audits
Schedule quarterly security audits to assess your company’s current vulnerabilities and make improvements where needed. Audits can identify outdated protocols, weaknesses in your system, and areas where your team may need additional training.
Update Policies Based on Emerging Threats
Stay informed about the latest smishing tactics, particularly those targeting businesses. Adjust your policies to address new threats, whether they involve specific smishing tactics, social engineering schemes, or impersonation scams.
Reinforce Training on a Regular Basis
Consider holding biannual or quarterly refresher courses on smishing and other phishing scams to keep your team aware of potential risks. Regular training reinforces best practices, builds a culture of cybersecurity, and ensures employees are confident in spotting scams.
6. Prepare an Incident Response Plan
No matter how strong your security measures are, there’s always a risk that a scammer could bypass them. Prepare an incident response plan so your team knows what to do if someone accidentally engages with a smishing text.
Outline Steps for Containment and Recovery
If a smishing attack is detected, your incident response plan should outline the steps to contain the threat and prevent further damage. Key components of an effective response plan include:
- Immediate Device Isolation: If a device is compromised, isolate it from the company network to prevent malware from spreading.
- Password Resets: Require the employee to change passwords for any accounts potentially compromised by the smishing attempt.
- Reporting Procedures: Ensure employees report the incident to IT or management immediately to contain any damage.
Document and Analyze the Incident
After an incident, conduct a post-mortem analysis to understand how the smishing attempt occurred and what can be improved to prevent similar incidents in the future. This helps you strengthen your security protocols and identify areas for improvement in employee training or device protection.
Final Thoughts: A Proactive Approach to Smishing Prevention
Protecting your business from smishing requires a proactive, layered approach. Educating your team, implementing strong security protocols, using spam-blocking software, and establishing a clear response plan are all essential steps to minimize risk.
By fostering a culture of cybersecurity awareness and staying ahead of emerging threats, you can significantly reduce your company’s vulnerability to smishing. With vigilance, proper training, and the right security tools, your business can stay safe from these increasingly sophisticated text scams.
