Three Florida banks have had their Web sites compromised by hackers in an attack that security experts are calling the first of its type. Earlier this month, attackers were able to hack servers run by the ISP that hosted the three banks' Web sites. They then redirected traffic from the legitimate Web sites to a bogus server, designed to resemble the banking sites. Users were then asked to enter credit card numbers, PINs and other types of sensitive information, he said. The affected banks are Premier Bank, Wakulla Bank, and Capital City Bank, all small regional banks based in Florida. The three banks in question could not be reached to comment for this story, but Premier Bank is now asking customers to change their passwords after the bank was notified of a phishing scam, according to a note on the company's Web site.
