A small electric cooperative was the apparent victim of a ransomware attack that caused significant disruption and damage last month. On November 7, Delta-Montrose Electric Association (DMEA) discovered a breach on its internal enterprise network. As a result of the attack, the utility lost 90 percent of its enterprise network functions and large amounts of data, including saved documents and spreadsheets. The power grid and fiber optic network, including internet services managed by the utility were reportedly not affected.
