Ransomware attacks on schools and colleges | Kaspersky official blog
Back when ransomware was just a startup industry, the primary goal of the attackers was simple: encrypt data, then extort a ransom in exchange for decrypting it. Because of this, cybercriminals mostly targeted commercial enterprises — companies that valued their data enough to justify a hefty payout. Schools and colleges were generally left alone — hackers assumed educators didn’t have the kind of data worth paying a ransom for.
But times have changed, and so has the ransomware groups’ business model. The focus has shifted from payment for decryption, to extortion in exchange for non-disclosure of stolen data. Now, the “incentive” to pay isn’t just about restoring the company’s normal operations, but rather avoiding regulatory trouble, potential lawsuits, and reputational damage. And it’s this shift that’s put educational institutions in the crosshairs.
In this post, we discuss several cases of ransomware attacks on educational organizations, why they took place, and how to keep cybercriminals out of the classroom.
Attacks on educational institutions in 2025–2026
In February 2026, the Sapienza University of Rome, one of Europe’s oldest and largest higher education institutions, suffered a ransomware attack. Internal systems were down for three days. According to sources familiar with the incident, the cybercriminals sent the university’s administration a link leading to a ransom demand. Upon clicking the link, a countdown timer started on the site that opened — counting down from 72 hours: the time the attackers demands needed to be met. As of now, there’s still no word on whether the university administration paid up or not.
Unfortunately, this case isn’t an exception. At the very end of 2025, attackers targeted another Italian educational institution — a vocational training center in the small city of Treviso. Things aren’t looking much better in the UK, either: in the same year, Blacon High School was hit by ransomware. Its administration had to shut its doors for two days to restore its IT systems, assess the scale of the incident, and prevent the attack from spreading further through the network.
In fact, a UK government study suggests these incidents are just part of a broader trend. According to its 2025 data, cyberincidents hit 60% of secondary schools, 85% of colleges, and 91% of universities. Across the pond, American researchers also noted that in the first quarter of 2025, ransomware attacks in the global education sector surged by 69% year on year. Clearly, the trend is global.
Why schools and universities are becoming easy targets
The core of the problem is that modern educational organizations are rapidly incorporating digital services into their operations. A typical school or university infrastructure now manages a dizzying array of services:
- Electronic gradebooks and registers
- Distance learning platforms
- Admission systems and databases for storing applicants’ personal data
- Cloud storage for educational materials
- Internal staff and student portals
- Email for faculty, students, and the administration to communicate
While these systems make education more convenient and manageable, they also drastically expand the attack surface. Every new service and every additional user account is a potential doorway for a phishing campaign, access compromise, or a personal data leak.
According to a UK study, the primary vector for these attacks is basic phishing. But that’s not all that surprising: since the education sector was off the cybercriminals’ radar for so long, cybersecurity training for both staff and students was hardly a priority. As a result, even the most seasoned professors can find themselves falling for a fake email purportedly sent by the “dean” or the “school principal”.
But it’s not just the faculty. Students themselves often unwittingly act as mules for malware. In many institutions, students still frequently hand in assignments on USB flash drives. These drives travel across various home or public devices, picking up malicious digital hitchhikers along the way. All it takes is one infected USB drive plugged into a campus workstation to give an attacker a foothold in the internal network.
It’s worth noting that while USB drives aren’t as ubiquitous as they were a decade ago, they remain a staple in the educational environment. Dismissing the threats they carry isn’t a good idea.
How to ensure the cybersecurity of educational infrastructure
Let’s face it: training every literature and biology teacher to spot phishing emails is now easy, quick task. Similarly, the educational system isn’t going to cut down on USB usage overnight.
Fortunately, a robust security solution (such as Kaspersky Small Office Security) can do the heavy lifting for you. It’s ideal for schools and colleges that need set-it-and-forget-it protection without a steep learning curve. Plus, it’s affordable even for institutions operating on a tight budget, and doesn’t require constant management.
At the same time, Kaspersky Small Office Security addresses all the threats we’ve discussed above: it blocks clicks on phishing links, automatically scans USB drives the moment they’re plugged in, and prevents suspicious files from executing on devices connected to the school’s network.
