The computer systems in a Keys were down for a week due to a . The problems were made worse as right as district was bringing up some administration and school computers, Comcast suffered a day-long outage due to a cut fiber.

Monroe Country School District was the of a ransomware attack. , first spotted in January, was dubbed the leading ransomware threat in July. A school district employee working on payroll discovered undisclosed problems on Sunday, September 9, and submitted an IT ticket. IT contacted Symantec and was advised to bring it all down and secure the system.

Pat Lefere, executive director of operations and planning for the district, told the Miami Herald, “This particular one was a that Symantec hadn’t seen before. They took all of our files and created a patch for us. It was applied to all servers before bringing them back up.”

Symantec shows the latest detected GandCrab ransomware discovered on Wednesday, Sept 12, but it may not be the variant which hit the Florida school district as the IT department thought it had fixed the problem on Tuesday morning. Yet upon bringing the system back up, they saw the same issues as when the ransomware was discovered on Sunday and shut the system down again.

“We haven’t had any access to data that was inappropriate nor have we had lost data,” district superintendent Mark Porter later told the Miami Herald. “The bad news is we haven’t had the type of access our employees are used to.” The cyberattack did not affect payroll, but it did affect delivery of students’ mid-quarter progress reports.

Monroe County School District claimed there were no ransom demands, but since ransomware locks up a system and demands payment to retrieve a decryption key for encrypted files, perhaps the district meant it didn’t cave to extortion? Lefere said, “That only happens for folks that don’t back up their stuff and are so desperate. We recover our files from the last backup.”

The district’s website was back up by Wednesday, but the computer systems remained partially down on Thursday. Lefere said the district rebuilt “each server from scratch to make sure they’re clean.”

Within 30 minutes of the IT department bringing up the computers at four schools and the administration office on Thursday, Comcast went down. Comcast, in turn, blamed the internet outage on a fiber cut.

The system was expected to be up and running on Friday. Unlike many businesses and even government entities hit by ransomware attacks, at least the Florida Keys school district did have backups.

There have been 364 K-12 cyber incidents since January 2016; of those, the US schools hit by ransomware are denoted with yellow pins on a map. The biggest collection of yellow pins is in Texas and related to 2017 ransomware attacks.
