Bank holding company First Horizon Corporation disclosed some of its customers had their online banking accounts breached by unknown attackers earlier this month. First Horizon discovered the attack in mid-April 2021 and said that it only impacted a limited number of customers. Unknown threat actors could breach the customers’ online bank accounts using previously stolen credentials and by exploiting a vulnerability in third-party software. The attackers were also able to gain access to customer information stored in the breached accounts and drain funds from some of them before their intrusion was discovered. The bank holding firm reimbursed all the impacted customers for their stolen funds.
