2019 Baltimore ransomware attack
Appearance
On May 7th 2019, most of Baltimore City's systems were infected with a new and aggressive RobbinHood ransomware variant and all servers, with the exception essential services, were taken offline. In a ransom note, hackers demanded 13 bitcoin (roughly $76,280) in exchange for keys to restore access. The note also stated that if the demands were not met within 4 days, the price would increase and within 10 the city would permanently lose all of the data. [1][2][3]
