The Federal Reserve of St. Louis found its DNS settings had been changed to redirect people to fake Web pages. Those who visited the fake pages may have been exposed to malware or had their login credentials stolen. The bank said the rogue web pages were designed to look like its research website. The DNS is a global database that resolves domain names into IP addresses that can be called into a browser. It’s powerful since a person can be directed to a different IP address even if they type in the correct domain name.”]
