Smishing: Definition, Examples & Protection

Security Boulevard

Cybercriminals no longer rely only on email to launch phishing attacks. With text messaging now a primary way people interact with businesses, attackers have shifted their focus to SMS, turning a trusted communication channel into a powerful weapon. Smishing doesn’t just put individuals at risk; it creates openings for account takeover, supply chain disruption, and brand damage. 

Understanding how smishing works and why traditional defenses aren’t enough is the first step toward building stronger safeguards.

Main points

• Smishing exploits trust in SMS – Attackers use text messages to trick people into clicking malicious links or sharing credentials, making it harder to detect than traditional phishing.

• The risk extends beyond employees – Customers, partners, and supply chains can all be compromised, leading to financial losses, regulatory penalties, and reputational damage.

• SMS-based auth is a prime target – Fraudulent OTP prompts are a common tactic, which is why organizations should move away from SMS authentication.

• Passwordless is the strongest defense – Passkeys, magic links, and authenticator apps remove SMS from the equation, protecting against smishing while improving user experience.
