Public schools in Baltimore County will remain closed on Monday and Tuesday, officials said, as officials respond to a cyber attack that forced the district to cancel remote classrooms for its 115,000 students just before the thanksgiving holiday, The officials said.
The attack was detected late Tuesday, affecting the district’s websites and distance education programs, as well as its grading and email systems. Officials told WBAL-TV.
Schools were closed on Wednesday, a day earlier than scheduled for Thanksgiving. On Saturday, the district Announced on twitter Classes will be closed for two additional days on Monday and Tuesday “due to ransomware attack”.
on Sunday, The district said on Twitter However, schools would be closed, but it was safe to use the Chromebook issued to students, as there were Google accounts associated with the school. The district said students should not use the Windows-based devices they had issued “until further notice”.
At a news conference on Wednesday afternoon, officials were unable to say when school operations would begin. “We don’t know, at this point, a timeline,” Superintendent Drs. Daryl L. Williams said.
Kathleen S., president of the Baltimore County Board of Education. Kosse said the situation was “very disturbing”. The students, he said, were “trusting us to provide education and other opportunities.” Authorities declined to give details of the attack, including demands.
The Baltimore County district began the 2020-21 school year with all of its students learning remotely – a period of “virtual instruction” that the district said would continue until at least January. Later, the district said it hopes to offer a “hybrid” plan that includes “targeted to students” instruction “on a rotating basis” for a few days a week. The district will allow students to continue learning remotely full-time, if they wish.
Coronovirus, which can spread easily when people gather distance education, students and teachers with little time to prepare.
The digital infrastructure that makes distance education possible is now increasingly seen as a target of cyber attack. Schools are storing more data online without sophisticated plans to keep it safe, and are susceptible to public pressure when that data is compromised, said Raven Aronashvili, founder and chief executive officer of cyber airsensitivity firm CYE said.
In local governments and schools in particular, “cybersecurity is considered to be significantly lower in maturity level,” Mr. Aronashvili said in an interview.
Increasingly, ransomware attacks occur on the face of cyberbax schools, in which the user locks down their data by an unauthorized person who promises to unlock the data when the ransom is paid.
The same happened to Baltimore County Public Schools, according to Jim Cornes, executive director of the district for information technology. At a news conference last week, he said the district’s data was neither stolen nor released, but was closed in such a way as to prevent school officials from operating.
“This is a ransomware attack that encrypts the data as it sits and cannot access or delete it from our system,” Mr. Corns said. “So we are conflating it as a ransomware attack.”
Mr. Aronashvili said that ransomware “mainly works on pressure elements.”
“If you are able to exert enough pressure, someone will pay,” he said. “In the end, this is the whole business model.”
For example, banks’ financial data is usually tightly secured and its owners usually have well-established rules against giving ransom, Mr. Aronashvili said. Local governments and schools typically have a lot of personal data and less sophisticated plans to acquire it or deal with attacks.
Have noticed the attackers.
According to The K-12 Cyberspace Resource Center, Which tracks incidents in schools across the country, at least 44 school districts have reported ransomware attacks so far this year. The figure was 62 last year. In 2018, There were only 11 reports.
Center founder Doug Levine said that he expects the same number of ransomware incidents to be eliminated by 2019. He cautioned that not every attack could be included in the data, as there is no uniform standard regarding incidences of disambiguation in school districts.
“Since the epidemic, when a school district experiences any event, learning stops,” Mr. Levine said. “It is the loss of flexibility that Kovid has brought to light.”
At the news conference last week, Baltimore County Police Department Chief Melissa R. Hyatt declined to give details of the investigation, but said local, state and federal officials were helping.
On Wednesday, about 10 hours later The school district confirmed the ransomware attack on Twitter, FBI field office in Baltimore Was aware of this incident But declined to comment further.
On Sunday, a spokesman for the Baltimore County Police asked questions from county school officials. Messages left for school officials were not immediately returned.
