Ransomware attacks remain an ongoing threat to research and higher education (R&E) institutions. 

According to a report from Comparitech, a cybersecurity and online privacy product review website, there were 130 confirmed and unconfirmed ransomware attacks against colleges, universities, and K-12 schools in the first six months of 2025 alone.

While the number of ransomware attacks is on the rise, the attacks themselves are becoming increasingly sophisticated.

“The threat of ransomware attacks is significant. R&E institutions have the challenge of protecting sensitive data and ensuring operational continuity, all while facing shrinking budgets,” said Sarah Bigham, lead security analyst at Indiana University – REN-ISAC.

At the 2025 Internet2 Technology Exchange (TechEX25), held Dec. 8-12 in Denver, Colo., Sarah will lead the session “Ransomware in Higher Education,” to help R&E institutions prepare for and mitigate ransomware attacks.

Ahead of her TechEX25 session, we sat down with Sarah to learn more about growing trends in ransomware attacks. Here is a preview of what attendees can learn from Sarah at her session.

What other TechEX25 sessions will you be attending?

“Agentic AI – What lies ahead for Higher Education” looks very interesting, and I’m very much looking forward to it.


What are some trends in ransomware attacks you have observed in the past 24 months?

Sarah: The median ransom demand in higher education fell from $3.55 million to $697,000 in the last year, among the lowest demands across all industries. 

The median ransom payment also fell sharply from $4.41 million to $463,000. That moved R&E from being one of the highest payers of ransomware attack demands in 2024 to among the lowest in 2025.

It has become evident that higher education is recovering more quickly from attacks, with 59% of victims (up from 30% in 2024) fully recovering within a week.

What are some of the consequences of ransomware attacks that you have seen?

Sarah: The consequences of falling victim to a ransomware attack are endless; however, the most severe are financial, operational, legal, and reputational.

What is the #1 piece of advice you would give to colleagues to protect themselves against ransomware attacks?

Sarah: You must know your environment better than the adversary. Unfortunately, that has been the Achilles’ heel of many organizations during ransomware attacks.

What are some of the key points you will cover in your session?

Sarah: I will discuss the evolution of attacks, adversary trends, methods for detecting attacks, and the pros and cons of paying the ransom.

What are some takeaways you want attendees to walk away with after your session?

Sarah: Knowing the top attack vectors is key to hardening your environment. 

I want attendees to know what these attack vectors are and the variants that use them. We will also go over several new ransomware variants and how they affect the R&E community.

Information Security and More at TechEX25

Sarah’s session on ransomware attacks against R&E institutions is part of the Information Security Track at TechEX25. Other session topics in that track include alerting and response automation, access management, using artificial intelligence to combat cyber attacks, and much more.
