Hackers used phishing emails to break into a Virginia bank in two separate cyber intrusions over an eight-month period, making off with more than $2.4 million total. Now the financial institution is suing its insurance provider for refusing to fully cover the losses.
According to a lawsuit filed last month in the Western District of Virginia, the first heist took place in late May 2016, after an employee at The National Bank of Blacksburg fell victim to a targeted phishing email.
The email allowed the intruders to install malware on the victim’s PC and to compromise a second computer at the bank that had access to the STAR Network, a system run by financial industry giant First Data that the bank uses to handle debit card transactions for customers. That second computer had the ability to manage National Bank customer accounts and their use of ATMs and bank cards.
Armed with this access, the bank says, hackers were able to disable and alter anti-theft and anti-fraud protections, such as 4-digit personal identification numbers (PINs), daily withdrawal limits, daily debit card usage limits, and fraud score protections.
