US Bank Identifies and Blocks TDoS Attacks with SecureLogix
A large US Bank was the victim of several TDoS attacks that paralyzed their voice network, blocking all ingoing and outgoing calls across multiple branches for days on end. After deploying the ForceField Call Security solution from SecureLogix the same bank https://securelogix.com/threats/tdos-attacks/was able to block repeated TDoS (Telephony Denial of Service) attacks. Eventually, the frustrated hackers gave up and moved on to easier prey.
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.
The source of the TDoS attacks was a sophisticated criminal fraud and extortion team. Deployment of the Force Field voice security solution gave the bank real-time visibility and control over all inbound and outbound voice traffic. Force Field provided real-time alerts to identify patterns of suspected fraud and TDoS calls, and to block TDoS attacks before they impacted business operations.
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 block TDoS attacks and block further operational disruption and loss of phone service transactions.
