SMS Phishing (Smishing)
Phishing
SMS phishing, commonly known as smishing, delivers phishing attacks through text messages to mobile devices. Attackers send fraudulent SMS messages that impersonate banks, delivery services, government agencies, or other trusted entities, containing malicious links that direct victims to credential harvesting pages or trigger malware downloads. The intimate and immediate nature of text messaging makes smishing particularly effective.
Smishing has surged in prevalence as mobile devices have become the primary computing platform for most people. Attackers exploit several characteristics unique to SMS: messages appear in the same inbox as legitimate communications from known contacts, mobile browsers show truncated URLs that make it harder to identify fake domains, and the urgency-driven culture of text messaging encourages quick, unthinking responses. Common smishing scenarios include fake package delivery notifications, bank fraud alerts, tax refund notices, and account verification requests.
The infrastructure supporting smishing attacks has become increasingly sophisticated. Attackers use SIM farms, virtual phone numbers, and compromised messaging gateways to send millions of smishing messages at minimal cost. Some operations rotate through thousands of short-lived domains to evade blocklists, while others use legitimate URL shortening services to obscure the final destination.
