Ransomware Attacks Targeting Universities Are on the Rise

What Happened

The academic world has become a new target for cybercriminals. Cybersecurity data covering the first half of 2026 reveals a significant increase in ransomware attacks targeting higher education institutions. The "Education Sector Ransomware Report," published on July 23 by the cybersecurity research and comparison platform Comparitech, documents that attacks against universities and colleges increased by 8% in the six-month period between January and June compared to the last six months of 2025.

One of the main actors behind this concerning picture is the recently prominent ransomware operation known as "The Gentlemen." The report reveals that this group's attacks on the education sector showed a staggering 275% increase in the first half of 2026 compared to the previous six-month period. Even more striking is that 80% of the group's attacks in the education sector specifically targeted higher education institutions like colleges and universities. This indicates that the group is deliberately targeting academic centers.

According to Comparitech's data, a total of 104 ransomware incidents were recorded in the global education sector in the first six months of 2026. Of these incidents, 36 were officially confirmed as ransomware attacks by the victim institutions. The report also notes that despite this increase in higher education, there has been a decrease in the total number of incidents across the education sector as a whole. The main reason for this decline is a quarter-on-quarter decrease in attacks against K-12 schools, such as primary and secondary schools. However, experts warn that this overall decline should not lead to complacency.

Rebecca Moody, Head of Data Research at Comparitech, summarizes the situation: “This H1 report yet again emphasizes the impact one group can have on the threat landscape. While initially the dip in attacks makes for positive reading, further investigations reveal that this is largely due to one gang and its choice of target.” Moody added, “The Gentlemen has gained immense notoriety in recent months and, as our data shows, has focused on higher education institutions.” This analysis clearly shows that the threat has not disappeared but has merely shifted its target and become more sophisticated.

Data Compromised

While the Comparitech report focuses on the number of attacks and the perpetrators, it does not provide detailed information on what specific data was compromised in these 104 incidents. However, it is a known fact that universities, by their nature, house a wealth of diverse data that is extremely valuable to cybercriminals. The types of data potentially at risk in such attacks include:

• Personally Identifiable Information (PII): Sensitive data of students, faculty, and staff, such as names, addresses, social security numbers, dates of birth, and financial information.
• Academic Research and Intellectual Property: Universities store the results of years of research, patent applications, unpublished papers, and other valuable intellectual property. The leak or encryption of this data can cause irreparable harm to both the institution and the researchers.
• Financial Records: Financial data such as the institution's budget information, donor records, student tuition payments, and staff payroll can be used for fraud and extortion.
• Administrative and Operational Data: Data critical to the daily functioning of the institution, such as student grades, course schedules, admission applications, and disciplinary records. The lockdown of these systems can paralyze the university's entire operations.

Ransomware groups encrypt this data to make it inaccessible and demand large ransoms for the data to be released or to prevent it from being published on the internet.

How Did the Attack Happen

The source article and the Comparitech report do not provide specific attack vectors or technical details used by "The Gentlemen" or other attackers to infiltrate university networks. However, there are common methods generally used in ransomware attacks targeting the education sector. It is known that attackers often try the following ways to infiltrate these institutions:

• Phishing Attacks: In universities with thousands of students and staff, phishing emails are one of the most effective infiltration methods. Attackers send fake emails that appear to come from a legitimate source (e.g., the IT department, library, or dean's office) to steal user credentials or trick them into opening attachments containing malware.
• Exploitation of Vulnerabilities: The large and complex networks of universities may have unpatched software or misconfigured systems. Attackers can scan for these security gaps and gain unauthorized access by exploiting known vulnerabilities (CVEs).
• Weak Credentials and Brute-Force Attacks: Weak or default passwords used on remote access protocols (RDP) or other administrative interfaces are an easy entry point for attackers. Brute-force attacks, which use automated tools to try millions of password combinations, are common.

After infiltrating the system, attackers move laterally within the network to gain more privileges and take control of servers containing the most valuable data. In the final stage, they encrypt the data and leave a ransom note.

Who Are the Victims

The report clearly states that the United States is the geography most affected by ransomware attacks. Educational institutions in the US continue to be a primary target for cybercriminals. Although the focus of the attacks is particularly on higher education institutions, the victims are not just the university administrations. The ripple effect of these attacks extends to all areas of campus life:

• Students: Their personal data can be stolen, and their access to online course materials and grade systems can be cut off. An interruption during exam periods or application processes can directly affect their academic careers.
• Academics and Researchers: They can lose years of research data. They face the risk of their intellectual property being stolen or destroyed.
• Administrative Staff: They become unable to carry out the operational activities of the institution. Payroll, student registrations, and other administrative functions can come to a halt.
• The Institution's Reputation: A successful cyberattack can severely damage a university's reputation. This can negatively impact future student enrollments, donations, and research funding.

What You Can Do

It is critically important for universities to take proactive steps against this growing threat. Here are some basic measures that can be taken by both institutions and individuals:

For University Administrations:

• Multi-Factor Authentication (MFA): Implementing MFA for all critical systems, email accounts, and remote access points is one of the most effective defenses against password theft.
• Regular Backup and Recovery Plan: Regularly backing up critical data and storing these backups in an isolated manner (offline or in immutable cloud storage) is vital. An emergency plan should be created and tested to quickly restore systems after a potential attack.
• Security Awareness Training: Regular training should be provided to all staff and students to help them recognize phishing attacks, suspicious emails, and safe internet usage habits.
• Network Segmentation: Dividing the university network into smaller, isolated segments makes it more difficult for an attacker to spread across the entire network.

For Students and Staff:

• Be Cautious of Suspicious Emails: Be skeptical of emails from unknown senders, with unexpected attachments or links. Never reply to emails asking for personal or financial information.
• Use Strong and Unique Passwords: Create different and complex passwords for each account. Using a password manager can simplify this process.
• Keep Your Software Updated: Always update your operating system, browser, and other applications to the latest version to close known security vulnerabilities.

What the Company Says

Rebecca Moody, Head of Data Research at Comparitech, commented on the report's findings, warning against a superficial reading of the statistics. Moody states, "While initially the dip in attacks makes for positive reading, further investigations reveal that this is largely due to one gang and its choice of target," emphasizing that the threat is changing shape. She notes that the focus of "The Gentlemen" group on higher education institutions has increased the number of attacks in this area, while the decline in other areas can make the overall statistic misleadingly positive. This serves as an important warning that an improvement in one specific area of cybersecurity does not mean the threat has disappeared; rather, it shows that attackers are constantly searching for the weakest link and dynamically changing their targets.
