Critical Vulnerabilities in Legacy Telecom Infrastructure

A new whitepaper published by the Kenil Global cybersecurity team exposes critical flaws in legacy SMS routing architectures, and how our modern API protects against interception.

The Silent Threat of SS7 Attacks

Our cybersecurity research division recently published a comprehensive whitepaper detailing the widespread vulnerabilities present in legacy SS7 telecom architectures, which many low-cost SMS providers still utilize today.

How Interception Happens

Because legacy systems do not mandate end-to-end encryption between routing hubs, bad actors can exploit SS7 flaws to intercept One-Time Passwords (OTPs) and sensitive transactional alerts.

The Kenil Global Security Standard

We built our Bulk SMS and Voice Call APIs from the ground up to bypass these vulnerable nodes. By utilizing direct interconnects with major Indian telecom operators, we guarantee a secure, encrypted pipeline from our servers straight to the end user's device.
