Baltimore city government revealed Tuesday its network had been infected by a ransomware attack for the second time in a year, according to a Baltimore Sun article.
Lester Davis, spokesman for the Mayor, said that critical systems, including 911 and 311, were not affected, but that the majority of city servers were shut down. The effects ranged from a City Council committee canceling a hearing on gun violence to water customers being unable to get billing questions answered.
Previously the city had an ransomware attack on the phone systems that was found to be a variant the RobbinHood [sic] virus. The Robbinhood virus was also responsible for attacking the city of Greenville, NC, computer network in early April, 2019.
Ian Duncan and Colin Campbell of the Baltimore Sun article report:
The ransom message on Baltimore’s computer system said RobbinHood used a file-locking virus that encrypts files to take them hostage. The note demanded payment of 3 Bitcoins (equivalent to about $17,600 at current prices) per system, or 13 Bitcoins (worth about $76,280) in exchange for freeing all the city’s systems.
