Online learning at Tyngsboro High School and Middle School was temporarily halted Friday as officials investigated a potential cyberattack, according to WBZ-TV.
Police said the disruptions may have originated from devices brought into the school buildings, noting that that they were so-called “denial-of-service” attacks, according to the Lowell Sun.
“While we are confident that we will soon rectify this situation, I am upset for the difficulty and disruption this has caused our students, families, and staff," Superintendent Dr. Michael Flanagan said in a statement, the WBZ-TV reports.
A denial-of-service attack prevents users from accessing information systems, devices or other network resources because of the actions of the malicious user.
The district hopes to resolve the issue by Tuesday, WBZ-TV reports.
On Thursday, Springfield school officials abruptly paused remote learning to investigate possible IT threats. The district dismissed students Thursday morning and said remote learning was suspended because of the threats to the district’s IT network.
School officials in Springfield said virtual instruction resumed Friday.
