1. Artificially Inflated Traffic (AIT) & SMS Pumping
Developers today face a major financial threat known as AIT (Artificially Inflated Traffic) or SMS Pumping. Attackers program malicious bots to trigger thousands of verification requests on your application's open API endpoints.
These requests are routed to high-cost premium numbers in colluding foreign carrier networks. Startups wake up to find their communication provider invoices inflated by tens of thousands of dollars in a single night.
In our cryptographic verification model, there are no outbound SMS requests generated by your server, meaning zero financial incentive for attackers to target your API.
2. Structural Security Challenges in Legacy Systems
Beyond cost, legacy verification methods face security challenges. Traditional messages travel over older telecommunication routing protocols which can sometimes be intercepted.
Additionally, techniques like social engineering can lead to unauthorized access, where attackers redirect verification codes to their own devices.
3. ReOTP: Shifting the Economic Burden
ReOTP utilizes a modern, cryptographic authentication mechanism directly via the user's secure messaging app. This eliminates legacy telecom routing completely.
