About two years ago, a small, ruralbased credit union received a call from the Federal Bureau of Investigation (FBI) letting them know they had been hacked.

With less than a dozen computers tethered to a network managed by a third-party vendor, the credit union officials were informed an employee had fallen for a phishing scam and opened a malicious link in an unsolicited email. That malware quietly unleashed code to remotely comb through computer files. It turned out, there was little rummaging required; the credit union employee’s desktop included an unencrypted Word file with all the passwords needed for daily functions. A subsequent inspection also showed that key servers were exposed to malware when employees used them for general functions such as web browsing and email.
