US Bank Identifies and Blocks TDoS Attacks with SecureLogix

Summary

A large US Bank is the victim of several TDoS attacks that paralyze their voice network, blocking all ingoing and outgoing calls across multiple branches for an extended period. After deploying the ForceField Call Security solution from SecureLogix the same bank successfully mitigates repeat TDoS attscks from the original hackers and gets them to discontinue their efforts.

“SecureLogix turned the tide on our attackers — we got the protection we needed fending off multiple repeated attacks and the attackers gave up and went looking for easier prey.”

Challenge

A large, U.S. regional banking institution was the target of several Telephony Denial of Service (TDoS) attacks, resulting in the loss of all telephone/voice services across multiple retail branch locations for an extended period. During the attacks, all legitimate inbound customer transaction calls and outbound business traffic were prevented, generating substantial financial losses and negative customer reactions.

Solution

The source of the TDoS attacks was a criminal fraud and extortion operation. Deployment of the SecureLogix® voice security solution gave the bank real-time visibility and control over all inbound and outbound voice traffic. The solution provided real-time alerts to identify patterns of suspected fraud and TDoS calls, and blocked calls from the attackers before they impacted business operations.

Result

Following deployment of the SecureLogix solution, the original attackers launched additional TDoS attacks against the bank, including attacks from new sets of source phone numbers. These attacks were quickly identified and blocked. After several unsuccessful attempts, the attackers discontinued their attacks. With an ability to now see and block malicious and threatening calls in real-time, the bank is able to prevent TDoS attack calls and block further operational disruption and loss of phone service transactions.
