Nation-Wide Banking Institution Defeats Call Pumping


A massive flood of illegitmate inbound calls to this major nation-wide banking institution’s 1-800 number represented more than just a nuissance. It was a sophisticated scheme to inflate the bank’s phone expenses and create a payday for the fraudsters. With Force Field from SecureLogix the bank was able to stop this textbook case of call pumping dead in its tracks.

“We knew something was wrong our 800 number was being plagued with thousands of bogus calls and we were bearing the expense, but we didn’t know what to do about it until SecureLogix helped us identify the call pumping attack pattern and put technology in place to stop it.”


A U.S. nation-wide banking institution experienced call pumping attacks in the form of thousands of calls into the bank’s 1-800 contact center numbers. The motivation for the attack is financial. The bank pays the network service provider/carrier a fee to deliver 1-800 calls, and the carrier shares the fee with any other carriers involved in transporting/processing the call. The perpetrators establish fraudulent phone companies and send floods of calls targeting 1-800 numbers to collect a percentage of the carrying fee for each call, while increasing the telecom costs for the targeted organization.


The bank used Force Field from SecureLogix® to identify patterns of calling activity indicative of call pumping, including calls into the contact center’s IVR that never attempt to authenticate, and potentially block these fraudulent calls.


The bank was able to identify and block call pumping attacks and reduce their costs while receiving and processing their normal amount of legitimate business calls and transactions.
