Safeguard your SMS authentication channels from costly fraud with Authgear's advanced SMS Pumping Detection. Our intelligent system identifies suspicious patterns and stops attacks before they drain your budget.
SMS pumping fraud is a sophisticated attack where bad actors exploit SMS-based authentication systems by generating excessive message traffic using fake or automated phone numbers. This artificial traffic inflation can cost businesses millions in fraudulent charges while degrading legitimate user experiences.
Without proper monitoring tools, SMS pumping can be difficult to detect until significant damage is done. Here are key indicators that your business might be under attack:
If you notice OTP requests coming from regions or countries where you don't normally operate, this could signal fraudulent activity. Pay attention to successful OTP attempts from locations where you don't have a legitimate customer base.
Sudden, unexplained surges in SMS traffic—especially for OTP requests—often indicate bot activity. Unless you're running a promotion or campaign, these spikes warrant immediate investigation.
One telltale sign of SMS pumping is receiving OTP requests from phone numbers with sequential patterns (e.g., numbers ending in 1000, 1001, 1002). The chance of multiple people with nearly identical phone numbers requesting OTPs simultaneously is virtually zero.
A noticeable drop in OTP conversion rates can indicate that fraudsters are sending requests without completing the authentication process. If your typical conversion rate falls by 20% or more, SMS pumping could be the culprit.
If you're burning through your SMS budget faster than usual, it's likely that SMS pumping is affecting your business. This is often the most painful symptom that finally triggers investigation.
Our advanced detection system uses machine learning algorithms to identify and block fraudulent SMS traffic before it impacts your business. Unlike basic security measures, our solution provides comprehensive protection against sophisticated SMS pumping attacks.
