Why is DCB Fraud Problematic for Telcos


Carrier billing was once considered one of the safest transaction methods, but this is a myth. Mobile Network Operators (MNOs) offer internet and communication services to their customers as part of their telecommunications package. As a result, whenever fraud occurs in the Direct Carrier Billing (DCB) ecosystem, it causes panic among network consumers.

Malware, bots, phishing emails/SMS, and other sophisticated methods are used by cybercriminals to target device users. Their undetectable and constantly evolving mechanisms directly impact the growing reliance on mobile subscriptions. According to light reading, mobile Internet users will reach 60% of the world’s population, or 5 billion, by 2025, and DCB service subscriptions will likely increase. 

As the number of mobile internet users and DCB’s Value Added Service (VAS) subscriptions grows, fraudsters will increasingly target customers, merchants, and network operators to profit financially. For various reasons, online transaction threats in the DCB subscription model have become a concern for Telco’s.

DCB Fraud Threatens Mobile Network Operators (MNOs)

Loss of Consumer Trust and Market Credibility

Customers who conduct transactions using carrier billing have placed their trust in MNOs. However, cybercriminals’ blatant disregard for consumer trust is evident during financial fraud. Furthermore, users blame MNOs and merchants for losing money on untendered VAS subscriptions that appear on their bills.

While rising customer complaints remain a flaw in the overall operation, the loss of revenue from repaying a sufficient amount to a larger group of users results in a financial blowback to the Telco network. As a result, it is a constant battle for brand custodians to make deliberate efforts to restore user trust and ensure brand credibility.

Customers become victims of financial fraud on other associated apps and fraud in the brand’s DCB transaction-based apps. According to polymer users’ digital identities are sold for as little as $15 on the dark web.
