Ransomware attacks against schools are surging, researchers find

The number of schools targeted by ransomware attacks in 2019 is still climbing, with 10 more victims identified in just the past nine days, according to researchers at the cloud security firm Armor, including a community college that was hit with a $1.6 million demand from hackers that had been lurking on its network for months before going active.

In total, 49 educational institutions or public school districts have been infected in 2019, Armor found. The academic sector is the second-most common target of publicly disclosed ransomware attacks, trailing only the estimated 70 municipalities that have been struck by payday-seeking hackers.
Like small local governments, schools are “targets of opportunity” that are often “behind the curve in terms of security and countermeasures,” said Chris Hinkley, the head of Armor’s Threat Resistance Unit.

Perhaps more notable is that several of the attacks directed at schools appear to have come by route of a third-party service provider, Hinkley said.

“It’s a possibility where an organization that is providing services to schools might be attacked and it goes to the schools,” he told EdScoop.

Report: Schools One of the Biggest Targets for Ransomware
School districts have seen a stark rise in cyberattacks in just the last several years, according to the newly released report
October 10, 2019
https://www.govtech.com/security/Report-Schools-One-of-the-Biggest-Targets-for-Ransomware.html

This summer, K-12 schools saw an unprecedented rise in cyberattacks, with schools being hit more in those months than throughout the whole of 2018.

That's according to a new report from endpoint resilience firm Absolute. The report was compiled after a survey of data from over 1,200 K-12 organizations and claims schools are the second most popular target for ransomware attackers next to local governments.
Ironically, increased digital literacy and more complex IT landscapes in schools may actually be escalating risks.

That's because students — now almost always digital natives — are provided with more connected devices by schools than ever before.

"It's much tougher to tell a fifth grader not to click on ransomware," Wyatt said. "They're much more vulnerable. And so I think we have to do more to reach out and not just educate the community about what the risks are, but give them access to resources so that when something starts to go wrong they can respond and adequately protect themselves."

11 New US School Districts Compromised by Ransomware; 72 in 2019
December 17, 2019
https://www.securitymagazine.com/ar...istricts-compromised-by-ransomware-72-in-2019

Eleven new U.S. school districts (comprised of 226 schools) have been compromised by ransomware since late October, says a report by Armor.

Since January 2019 to date, Armor has identified a total of 72 school districts and/or individual educational institutions that have publicly reported being a victim of ransomware. These attacks have potentially impacted 1,039 schools nationwide.
Of the 11 school districts hit in this last attack wave, only one has reported having paid the ransom, but did not disclose the sum (Port Neches-Groves), 3 reported having refused to pay and seven have not revealed whether they have paid the ransom or not.

Cyberattacks Force Schools to Bolster Online Security
March 17, 2020
https://www.edweek.org/ew/articles/...force-schools-to-bolster-online-security.html

The notification came in at 5:30 a.m. that something was wrong with the servers in the Cherry Hill School District outside Philadelphia. By 7:30, Wi-Fi was down. Email too.
And although learning was uninterrupted, the experience last fall was more than just a technical nightmare, Meloche said. The district had to explain to parents why they were unable to email their child's teacher.

"It seemed like, 'Wow, the district is falling apart,' but we were actually functioning and functioning well," said Farrah Mahan, Cherry Hill's curriculum director.
Cherry Hill is far from alone.

One possible explanation: School hacks are increasing because K-12 school systems are so reliant on technology and have potentially valuable data on students and employees, Levin said.
Serious Consequences
Some systems, including Alabama's Houston County school district, have had to close or postpone classes. The Rockville Center School District outside New York City paid hackers $100,000 to recover its data, according to local news reports.
Back in September, Louisiana Gov. John Bel Edwards, a Democrat, declared a statewide emergency after school systems in three parishes were hit by cyberattacks.
Click to expand...

Back Up Computer Systems
Districts also need to do some technical work, including backing up their systems, and testing those backups.
Many districts are already working on backups, according to the CoSn/Education Week survey of 513 K-12 technology leaders in the United States Seventy-three percent of education technology leaders suggested they were backing up all information and storing it off site in case of an attack.

Sometimes, hackers demand a ransom for restoring a district's data. McLaughlin's advice: Don't pony up. "I would certaintly recommend against paying, because it's just like kidnapping," she said. "People will continue to do that if they continue to get rewarded."
Click to expand...

Another piece of wisdom from district leaders who have weathered attacks: Be sure to put some money aside in case the worst happens. Bob Blalock, the technology coordinator in Houston County, said his district might have ended up in a tight financial spot without some funding in reserves.
"We were very fortunate we had some budget for an emergency situation," he said. "We are not an affluent school system." (Blalock declined to say just how much the district spent rectifying the situation other than that it was "very expensive.")

Pandemic Could Make Schools Bigger Targets of Ransomware Attacks
April 13, 2020
https://www.darkreading.com/attacks...-targets-of-ransomware-attacks/d/d-id/1337549

Schools and colleges could become big ransomware targets for attackers looking to exploit the sudden surge in distance learning caused by the COVID-19 pandemic.

Between Jan. 1 and April 8, at least 17 school districts and colleges — comprising 284 entities — were hit by ransomware attacks. That was more than double the total of eight school districts and colleges that were hit in similar attacks during the same period last year, security vendor Armor said in a report this week.

"There is a very strong possibility that the [ransomware] attacks against schools and colleges will increase," Hinkley says.
Attackers know that academic institutions cannot fall back to teaching students in person and therefore are more likely to be pressured into paying a ransom to regain access to their systems.

"We do believe that the ransomware threat actors will continue their activity and certainly will not curb it, as this situation gives them an advantage," Hinkley says.
Click to expand...

Of the 17 school districts and colleges that were hit in ransomware attacks this year, only two publicly stated they were not going to pay, Hinkley says. It's unclear whether any of the others paid a ransom to get back access to their systems.
"We do believe the costs for recovery and to resume in a stable, functional state will depend on the reliability and extensiveness of the school's backup system, the breadth of the damage created, and the security protections needed to prevent a similar attack from happening a second time," Hinkley says.

FBI warns K12 schools of ransomware attacks via RDP
June 25, 2020
https://www.zdnet.com/article/fbi-warns-k12-schools-of-ransomware-attacks-via-rdp/

The US Federal Bureau of Investigation sent out on Tuesday a security alert to K12 schools about the increase in ransomware attacks during the coronavirus (COVID-19) pandemic, and especially about ransomware gangs that abuse RDP connections to break into school systems.

The alert, called a Private Industry Notification, or PIN, tells schools that "cyber actors are likely to increase targeting of K-12 schools during the COVID-19 pandemic because they represent an opportunistic target as more of these institutions transition to distance learning."

"K-12 institutions have limited resources to dedicate to network defense, leaving them vulnerable to cyber attacks," the FBI said.
The FBI PIN included a series of recommendations for K12 schools and their IT staff.

A Third of UK Unis Hit By Ransomware in Last 10 Years
August 12, 2020
https://www.infosecurity-magazine.com/news/third-uk-universities-ransomware/

Around a third (33%) of UK universities have been targeted with ransomware, freedom of information (FOI) requests submitted by the agency TopLine Comms have revealed.

Of the 134 universities the requests were sent to, 105 responded. Of these, 35 (33%) revealed they had been subjected to attack while 25 (24%) said they hadn’t. The remaining 43 (45%) refused to answer, with the main concern being that admission of attack could lead to further targeting.
Of the 35 universities that admitted to having faced ransomware attack, 34 confirmed they did not pay ransoms, with just one, Liverpool John Moores, refusing to disclose whether they had paid a ransom or not.
Click to expand...

Speaking to Infosecurity about the findings, Steven Furnell, professor of cybersecurity at the University of Nottingham, commented: “The fact that a third indicated that they had been ‘subject to an attack’ really just serves to confirm the prevalence of the threat – which in itself is not a surprise, as we know ransomware has been a significant element of the threat landscape for the last few years.”

Back to school ransomware attacks
September 11, 2020
https://www.securitymagazine.com/articles/93331-back-to-school-ransomware-attacks

Recently, schools throughout the U.S. have endured delays in reopening after experiencing massive ransomware attacks that force the shutdown of critical information technology systems.

The Clark County School District, a school district that serves all of Clark County, Nevada, including the cities of Las Vegas, Henderson, North Las Vegas, and Boulder Cit, was also hit by a ransomware attack during the first week of school.
With the surge of technology use for teaching, learning and continuing school operations in today’s remote environment, schools have become even more vulnerable to cyberattacks.

These recent cybersecurity incidents only highlight the need for continuous vigilance as school staff, students, and parents adjust to remote learning.
Click to expand...

Chester Wisniewski, Principal Research Scientist at Sophos, warns that as ransomware gangs continue to increase the sophistication of their attacks, we are likely to continue to see targets being more strategically selected to maximize impact of their disruption.

"Hitting schools at the start of the school year certainly applies additional pressure to get back online, and we may see similar targeting around election day or the upcoming Christmas shopping holidays. It is heartening to hear that Hartford is not negotiating with the criminals behind this, and we hope this sets a new standard moving forward for others to follow.”
Ransomware threats are a pervasive threat that organizations face, notes Melody J. Kaufmman, cyber security specialist.

Schools remain 'easy target' for ransomware as Maze targets big K-12 systems
September 14, 2020
https://statescoop.com/schools-maze-ransomware-k12-easy-target/

Actors using the Maze ransomware are claiming credit for a recent string of attacks against large public school districts across the United States, just as students and teachers are returning to their mostly virtual learning environments.

Katie Nickels, the director of intelligence at the information security firm Red Canary, said that while ransomware attacks against K-12 education systems have become frustratingly commonplace, incidents at the start of a new school year defined by pandemic-imposed distance learning and dwindling funding are especially despicable.

“I am so outraged at these ransomware operators,” she said. “Schools are trying to get back in session. Teachers and students are dealing with enough without these challenges.”
But schools also remain, Nickels said, an “easy target” for ransomware actors, even more so with many districts being forced to adopt universal online education, broadening the potential attack surface.
Click to expand...

Meanwhile, attacks against schools continue to be among the most reprehensible, she continued.

“There aren’t really international laws or norms about what’s acceptable in cyberspace, but I feel like there should be,” Nickels said.
Now, she said, malicious actors see schools’ scrambling to reopen or remake their classrooms as a juicy target.

Safeguarding Schools Against RDP-Based Ransomware
September 28, 2020
https://www.darkreading.com/risk/safeguarding-schools-against-rdp-based-ransomware/a/d-id/1338943

The FBI has issued a warning to US K-12 school districts, advising them that they are being targeted by cyberthieves and should take extra precautions to secure their networks.

While the pandemic has opened new opportunities for cybercriminals, attacks on K-12 schools are nothing new. In fact, they have been on the rise for some time.
Most school districts now acknowledge that things will not be back to normal this fall, and they are planning hybrid learning solutions for the school year.
Click to expand...

While a K-12 school or school district may not have data worth millions, cybercriminals know that schools often lack the resources large corporations deploy to guard against cyberattacks, which makes them prime targets.
One specific attack vector the FBI has warned about is Ryuk ransomware, which is deployed via RDP endpoints, specifically students, parents, and teachers in the K-12 environment.
Click to expand...

Today's investment in securing online learning will also return long-term benefits. The pandemic has accelerated the digital transformation journey for many, and schools are likely to continue incorporating distance learning as an adjunct to the traditional classroom. So, getting it right today will protect schools, and the communities they serve, for years to come.

The 'real consequences' of ransomware against schools
October 20, 2020
https://statescoop.com/k12-ransomware-attacks-cybersecurity/

According to StateScoop’s Ransomware Attacks Map, there have been 131 incidents involving school districts across the United States since 2016, counting Yazoo County, though those are only the attacks that have been publicly disclosed; Liska and the panelists who joined him believe the true number to be much higher. And the slew of attacks has made ransomware a persistent threat to interrupt the education system, they said.

“Messing with kids has real consequences for our society,” said Harlan Greer, a cybersecurity and counterterrorism adviser to Sen. Maggie Hassan, D-N.H.
Many ransomware attacks against school districts have compromised personnel and financial data.

“It’s sort of a morbid joke that instead of a snow day, schools now have cyber days,” Liska said.

Ransomware surges in education sector in Q3 as attackers wait patiently for start of school year
November 13, 2020
https://blog.emsisoft.com/en/37193/...kers-wait-patiently-for-start-of-school-year/

The number of successful ransomware attacks on the education sector increased by 388 percent between the second and third quarters of 2020. It was a similar story in 2019. This is almost certainly not a coincidence.
In this report, we will examine the reasons for this trend and how there may be a window of opportunity for school districts to detect and remove ransomware before encryption can take place.

Audit Found Baltimore County Schools Lacked Data Security
Report Comes as District Struggles With Ransomware Attack
November 30, 2020
https://www.databreachtoday.com/audit-found-baltimore-county-schools-lacked-data-security-a-15478

The Baltimore County Public Schools system was notified by state auditors of several cybersecurity weaknesses the day before the district was hit with a crippling ransomware attack (see: Ransomware Attack Targets Baltimore County Public Schools).

The general audit conducted before the Nov. 24 ransomware attack found the school system ignored warnings in a 2015 state audit that the lack of security for its IT infrastructure made personally identifiable information and critical databases vulnerable to attack. The Baltimore Sun published the audit.

"Significant risks existed within BCPS computer network," the audit stated [...]

Although coping with the challenges posted by the COVID-19 pandemic makes maintaining adequate information security even more challenging, Levin says: "District cybersecurity practices in general have not kept pace with the adoption of technology.

https://www.bleepingcomputer.com/ne...hool-district-shut-down-by-ransomware-attack/

Ransomware operators have attacked the Huntsville City Schools district in Alabama, forcing them to shut down schools for the rest of the week and possibly next week.

The Huntsville City Schools district is the sixth-largest school district in Alabama, with almost 24,000 students, 2,300 employees, and thirty-seven schools.
On November 30th, just as students returned from Thanksgiving break, the school district performed an early dismissal of students after a cyberattack disrupted their IT systems.

"Students, families, and faculty and staff members should shutdown their district-issued devices and ensure the devices remain off until further notice. Additionally, stakeholders should avoid logging on any HCS platforms at both school and home," Huntsville City Schools district stated in a message to parents.

Senators press CISA to do more to stop K-12 ransomware
December 2, 2020
https://statescoop.com/senate-homeland-security-cisa-school-ransomware-brandon-wales/

Senators asked the new head of the Cybersecurity and Infrastructure Security Agency on Wednesday what more the agency can do to help public school systems across the country to defend themselves from digital threats like ransomware, which has disrupted virtual learning environments, seized up educational IT resources and — in some places — even delayed or canceled classes.

[...] the hearing mostly focused on the ransomware threat to state and local entities, and how great CISA’s role should be in protecting those agencies, especially schools.

“CISA works with all sectors,” Wales told Hassan. “We have a responsibility to help them.”
Recent ransomware incidents in school systems have had deleterious real-world effects, including the delay of the start of the school year in Hartford, Connecticut, and the cancelation of several days of classes in the past week in Baltimore County, Maryland. Data stolen in an attack against the school system in Fairfax County, Virginia, was published online after administrators refused to pay a demand.
Click to expand...

Speaking during the second panel, New Hampshire Chief Information Officer Denis Goulet said the rise in cyberattacks against K-12 organizations creates an opportunity to implement a “whole-of-state” approach toward IT security, in which the resources of the state government are leveraged in response to a local crisis.
“If you have a small-staffed school, you can’t throw sophisticated stuff at them,” Goulet said.

Baltimore County school officials have refused to share information with local police, the county attorney and state information technology experts about the catastrophic cyberattack that hit its systems last month, County Executive Johnny Olszewski Jr. said Friday.

In a highly critical letter sent to schools Superintendent Darryl Williams, the Democratic county executive called it “troubling” that school officials are not cooperating with county police, who want access to third-party consultants retained by the county school system to analyze the ransomware attack.
School officials have repeatedly declined to comment on whether they are in communication with the hackers.

Cindy Sexton, president of the Teachers Association of Baltimore County, called Olszewski’s letter concerning.

“Communication continues to be an area of concern in BCPS. Our educators, staff, students, families and community members deserve transparency,” Sexton said. “While we understand the need to keep some information private due to the ongoing investigation, we were all concerned when we read what’s in this letter.”

https://www.scmagazine.com/home/sec...tigation-into-education-ransomware-conundrum/

Three Democratic senators requested a federal auditing group look into how the national government assists local school districts in fighting the scourge of ransomware.

In a letter dated December 16, Sens. Maggie Hassan, D-N.H., Kyrsten Sinema, D-Ariz, and Jackie Rosen, D-Nev., requested the Government Accountability Office look into “efforts by Education, DHS, and other relevant federal agencies to assist school districts in securing themselves from cyber threats and the effectiveness of these efforts.”
The letter notes recent ransomware attacks against school districts in the senators’ home states and beyond, a problem the senators note is exacerbated by the increased use of computers in COVID-19-era telelearning.
