With 23–27 billion SMS fraud monitoring tool  sent every day,1 SMS fraud is a massive problem for consumers and businesses alike. This global issue comes in many forms – SMS toll fraud, smishing, malware spreading and more – but all share one common thread: bad actors misuse business SMS workflows for financial gain. The right SMS fraud monitoring tool can help you protect your users and stop this damaging behavior in its tracks.

SMS Pumping

This type of fraud occurs when bots target forms that trigger an automated SMS response – like appointment confirmations, password resets or notifications. By filling these forms with fake or sequential phone numbers, the bots spoof the SMS service and flood your system with messages. This can lead to inflated telecom bills, degrade user experience, and damage customer trust.

Real-Time IP Abuse Data: A Powerful Tool for Security Teams

To avoid this type of attack, implement a security solution that uses challenge-response steps to tell bots from real users, such as GeeTest CAPTCHA. The technology combines behavioral biometrics and dynamic security to detect and stop automated attacks by evaluating mouse movement, typing speed, device information and other factors. It works in tandem with rate limiting, device checks and other risk metrics to keep your system secure and your users protected from abuse.

The best SMS fraud monitoring tool will help you prevent these attacks by blocking suspicious requests before they reach the SMS initiation step. For example, placing an AI-driven bot management solution like GeeTest Bot Manager early in your login or account creation flows can block the attacks before they even start, reducing both operational costs and illegitimate telecom charges.
