June 2024 Summaries

International Revenue Share Fraud (IRSF), also known as SMS Pumping Fraud, is a financial scam exploiting the pricing structures of international calls and SMS to illicitly generate revenue for fraudsters. This scam often involves cybercriminals using premium-rate numbers to trick applications into sending fake SMS verification requests, resulting in high costs for the targeted businesses. The fraudsters, often collaborating with telecom carriers, benefit from revenue-sharing agreements meant to facilitate international communications. IRSF can lead to significant financial losses, reputation damage, operational disruptions, and legal penalties for affected companies, especially those involved in international SMS-based verification processes. Detecting IRSF is challenging due to its ability to blend with legitimate traffic, but businesses can monitor sudden spikes in verification requests and work with OTP providers to flag suspicious activity. Companies like Prelude offer solutions to protect against IRSF by using advanced fraud detection techniques and ensuring legitimate users are not adversely affected by these scams.

Prelude has become an essential partner for the social app Locket, which is managed by a small team but serves millions globally, by providing efficient and reliable SMS verification services. The case study highlights the challenges faced by Locket's CTO, Maxi Bustos, in optimizing operations for scale without expanding the team, particularly in markets like Vietnam and Saudi Arabia prone to SMS-related fraud. Prelude's mobile-first services offer competitive pricing, fast setup, and responsive customer support, enabling Locket to maintain functionality even in high-risk markets. With a user-friendly API and effective fraud detection, Prelude allows Locket to focus on growth without being bogged down by cumbersome bureaucratic processes typical of larger service providers.
