Baltimore Mayor Bernard C. "Jack" Young said he plans to update residents and employees Friday on the ransomware attack that crippled city government computers and servers on Tuesday.

"But we aren't paying them," Young said. "That's definite."

According to officails, the City was struck by the Robbinhood ransomware. The FBI is investigating after authorities announced hackers were demanding about $76,000 to unlock encrypted files in city computers.

Essential services like police and fire are still operational. However, Baltimore city and county residents remain unable to pay their water bills, even by phone. A number of other departmental phone lines are also down.

City employees were concerned that they would not get paid on Friday due to the attacks. Young confirmed that employees are expected to be paid on time. 

The same ransomware hit municipal networks in Greenville, North Carolina last month.

Last year, Baltimore's 911 system was struck in a ransomware attack.

Young spokesman Lester Davis says most residents won't notice an impact. But the mayor said city employees who can't work without computer systems may be asked if they'd be willing to help clean up the city if the attack takes longer than expected to fix.
