Telecom API Security: Stopping Fraud & Data Breaches in 5G Networks

In this blog, we will learn about Telecom API Security: Stopping Fraud & Data Breaches in 5G Networks.

Introduction

The telecom industry has witnessed a remarkable evolution over the past century. It has transitioned from landline telephones to portable mobile devices and now to modern smartphones. As one of the oldest industries, telecommunications have continuously adapted to new technologies, accelerating communication capabilities and embracing innovations that shape the future of connectivity.

Each generation of telecom technology, from 2G to the latest 5G, has introduced groundbreaking advancements to meet modern demands. The sector continues to push boundaries, shaping how communication influences industries and everyday life.

The Growing Threat of API Exploitation in Telecom

Telecom companies handle extensive databases that encompass vast amounts of consumer and corporate data, including sensitive personal details and transaction records. The industry’s reliance on APIs to facilitate seamless communication, data exchange, and backend processes has also made it a lucrative target for cybercriminals. Here are some of the major API attack scenarios affecting the telecom sector:

1. SIM Swapping through API Exploitation:

Attackers can exploit telecom APIs to initiate fraudulent SIM swaps, enabling them to intercept calls or messages, including those used for two-factor authentication (2FA).

2. Unauthorized Network Access

Exploiting APIs that manage network-level configurations, attackers can gain unauthorized access to private telecom networks or intercept user communications.

3. Data Breaches

Attackers target APIs that store confidential user information, such as names, phone numbers, national IDs, and email addresses.

When these APIs are exploited, sensitive information may be leaked, leading to identity theft or misuse of private data.

4. Transaction Manipulation

Cybercriminals can misuse APIs to carry out fraudulent transactions, such as illegally activating or keeping subscriptions active.

This kind of exploitation can result in severe financial losses for telecom providers, along with reduced consumer trust.

5. Identity Theft via API Exploits

APIs can be manipulated to fraudulently register telecom subscriptions using stolen national ID details.

If these subscriptions are used for illegal activities, the blame often falls on the unsuspecting individual whose credentials were stolen.

6. Phishing and Fraudulent Offers

Attackers often use fake telecom-related websites or apps that replicate legitimate ones.

Through phishing, users are deceived into providing personal details or financial information, leading to monetary loss or identity theft.
