Strengthening SMS Networks Against Modern Threats

Telecom networks today face an escalating threat from a growing underground model known as Fraud-as-a-Service (FaaS). It allows fraudsters to offer ready-made fraud kits, enabling scammers to exploit SMS networks for malicious purposes. The financial toll of these scams is staggering, with telecom operators, enterprises, and end-users all suffering the consequences.

The Rise of FaaS in SMS Fraud

Fraud-as-a-Service is fueling a global surge in SMS scams, hitting telecom operators with major financial and reputational damage.

FaaS and Its Impact on the SMS Network

FaaS works by enabling fraudsters to manipulate SMS traffic through various illicit methods, including:

  • Grey Routes & SMS Bypass Fraud: Fraudsters use unlicensed routes to bypass legitimate networks, leading to lost revenue for telecom operators and degraded service for customers.
  • SIM Farms: Criminals use large-scale SIM card farms to send out fraudulent messages in bulk, which are often used for scams or spam.
  • SMS Phishing (Smishing): Scammers use fraudulent SMS messages to trick users into sharing sensitive information, leading to identity theft or financial losses.
  • SMS Pumping Fraud: This technique involves tricking users into unknowingly sending premium-rate messages, adding charges to their phone bills.
  • Flash Calls vs. SMS OTP Fraud: Fraudsters use flash calls (calls that disconnect immediately) to verify accounts, bypassing SMS OTP (One-Time Password) authentication systems, leading to unauthorized access to accounts.
How Telecom Companies Are Fighting Back

To combat this growing threat, telecom companies are adopting advanced technologies and strategies:

  • AI-driven fraud detection: By analyzing SMS patterns in real-time, telecom companies can identify and block suspicious activity before it causes harm.
  • Next-gen firewalls & traffic filtering: Telecom companies can use firewalls and traffic filters to block grey routes and prevent unauthorized access to their networks.
  • Regulatory compliance & stricter authentication: Telecom operators must adhere to regulatory guidelines and implement stronger authentication methods to ensure secure SMS exchanges.
  • Cross-industry collaboration: Telecom companies must work together with other industry players against FaaS networks, sharing intelligence and tools to combat telecom frauds.

Fraud-as-a-Service is a growing threat to telecom networks, operators, and consumers. According to the Mobile Ecosystem Forum (MEF), 39% of consumers across ten surveyed countries encountered at least one SMS scam attempt in the past year. By understanding the mechanics of SMS scams and adopting next-gen AI-powered fraud management like Armour, telecom companies can protect their revenue, reputation, and customer trust.
