Computers affected: Baltimore city government computers
Financial damage: $18.2 million
In April, 2018, city officials in the city of Baltimore, M.D. realized that the files on their computers had been seized by destructive agents. Attackers sent a digital ransom note requesting three bitcoin (approximately $17,000) in exchange for each captive system or, if the city preferred, a lump sum of 13 bitcoin ($75,000) for all of them. Other cities such as Greenville, N.C., Amarillo, Tex. and Atlanta, G.A., have faced similar attacks, too.
