January 15, 2021 Chris DeMillo, head of information technology at the 500-truck Leonard’s Express out of New York, remembers a three-day period in June 2017 vividly. “Like it was yesterday,” he said. That was when he realized Leonard’s networks had been exposed in a phishing attack, and malware had made its way across the company’s networks, touching nearly all points of the operation over a three-day period. "At one point we brought everything down that was plugged into an outlet,” DeMillo said. “We were running on phone calls and paper notepads.” The company was able to fight off the attack and restore its operations in those three days without major ramifications, other than lessons learned.
