How it works

The steps of SMS toll fraud are:
SMS toll fraud is difficult to detect. Don’t let this scam spiral into major unexpected costs to your business.
Step 1
An attacker initiates a manual or scripted attack on a webpage to trigger SMS-based OTPs. Attackers can opt for high-volume attacks or low-and-slow attacks.
Step 2
The attacked app or website forwards the OTP request to a cloud communication provider.
Step 3
The provider forwards the request to a telecommunications carrier. Multiple network providers spanning international territories are involved before the OTP can reach the intended consumer.
Step 4
In that chain, a compromised carrier, colluding with an attacker, forwards the request to a “premium rate” number on a high-cost network. As a result, scammers exact an extortionate carriage fee, up to $1 or more per transaction.
Step 5
The originating sender (in this case, the web site or app) must absorb the inflated costs, resulting in thousands or millions of dollars in hidden costs each month.
