Enhanced Fraud Prevention Service for Telecoms

By Telecom Tech Outlook | Friday, January 25, 2019

Telecom fraud continues to account for more fraud complaints each year. Modern technology has led to the attack on new telecommunications fraud tactics. Most of the recent cases of fraud have occurred in Private Branch Exchange (PBX) systems. Now, PBXs have become more affordable, and the loss of fraud has increased for organizations without the knowledge or experience of telecom fraud. Fraud occurs when fraudsters gain unauthorized access to and use a PBX to make calls charged to the PBX owner.

Oculeus is a supplier of support systems for telecom companies for business and operations. The company has developed an automated anti-fraud system that can detect and stop fraudulent communication activities quickly. The Oculeus anti-fraud system offers the first-ever adaptation of an important cybersecurity technology that companies have used for a long time.

Oculeus recently launched a fraud prevention service to protect telecommunications systems in enterprises. The solution, Oculeus Protect, monitors call signaling within PBX and uses machine learning and behavioral analysis to evaluate the likelihood of call fraud. If the risk is considered high, the system can drop calls shortly after connection so that the fraud is minimized.

There are two parts of a call. One is the signaling that a call attempt begins. In essence, the PBX system gives a message that it has a call mentioning the destination and what must be done further. The signage also includes information about the end of the call.

The other feature is the call media—the actual content of the call. Invoices are based on the time taken by the call media. Oculeus examines the signaling specifically to understand whether or not the call is authorized in real time.

The company creates a company profile to give guidance to Oculeus. This profile identifies aspects such as the typical business hours and working days of the company, typical business regions, countries where calling would not normally be calling destinations, and other parameters.

After activating the Oculeus service, it learns the typical calling behavior of a company and looks for anomalous activity outside the profile and the normal behavior. Input from its wide customer community is also used by Oculeus to include known fraudulent call destination numbers. Destinations and costs can be assessed for fraud.
