The city of Baltimore, which recently experienced its second hack in as many years, certainly knows this. The current one is expected to cost the city $18 million, and it continues to disrupt city business activity. It took the city nearly 80 days after the attack to begin issuing water bills again. Baltimore's example is but one in a seemingly never-ending series of successful hacks of America's local governments, and it won't be the last.--BY DONALD F. NORRIS AND LAURA MATECZUN, THE BALTIMORE SUN / SEPTEMBER 4, 2019
