Colleges and Schools Now Top Targets for Online Threat Actors

Across the globe, a new kind of threat is targeting the very institutions dedicated to shaping the future: schools, colleges, and universities.

In 2024, experts warn that educational organizations have become prime targets for online threat actors, including nation-state-backed hackers and financially motivated cybercriminals.

A recent Microsoft report ranked the education sector as the third-most-targeted industry in Q2 2024—a stark indicator of the growing threat landscape.

Global Surge in Attacks

ESET threat researchers have documented a sharp rise in attacks from advanced persistent threat (APT) groups, particularly those aligned with China, North Korea, Iran, and Russia.

Between April and September 2024, Chinese APTs ranked education among their top three targets; North Korean actors placed it in their top two, with Iran and Russia not far behind.

This surge isn’t just theoretical. In the U.S., the K12 Security Information Exchange (SIX) logged over one cyber-incident per school day from 2016 to 2022.

In the UK, 71% of secondary schools and 97% of universities reported a significant security breach in the past year—far exceeding the breach rates seen in commercial businesses.

Why Are Schools at Risk?

The education sector’s unique combination of open networks, limited cybersecurity budgets, and large, diverse user populations make it attractive to attackers.

Many schools and universities struggle to fund robust security measures or hire expert staff, leaving dangerous gaps in defenses. The widespread use of personal devices (BYOD) and legacy technologies further expands their attack surface.

Moreover, these institutions often store sensitive personal information and valuable research data, making them irresistible to ransomware gangs and state-backed hackers alike.

A culture of openness—integral to academia—can inadvertently invite risk, as broad collaboration with external parties makes it challenging to enforce tight security controls.

Tactics and Techniques

Attackers employ various tactics, from email phishing and social engineering to sophisticated malware that evades detection by security software.

State-backed groups, such as Iran-aligned “Ballistic Bobcat,” have been observed injecting malicious code into routine processes to bypass defenses.

Ransomware remains the top concern, with attackers exploiting resource and personnel shortages to demand substantial payouts.

Despite these challenges, time-tested cybersecurity fundamentals remain the best defense. Experts recommend:

• Enforcing strong, unique passwords and multi-factor authentication
• Quickly patching vulnerabilities and encrypting sensitive data
• Implementing regular cyber-hygiene practices, like backups and user training
• Developing robust incident response plans
• Using managed detection and response (MDR) services to catch threats early

As cyber risks escalate, education leaders must recognize that safeguarding their digital infrastructure is now as vital as protecting their campuses.

The ability to provide quality education—and the trust of students and families—depends on it.
