The Top Five Ransomware Attacks in 2025

Learn How to Stay Safe!

Ransomware isn’t slowing down.

In just the first half of 2025, ransomware attacks have continued to wreak havoc across industries, from healthcare and education to manufacturing and hospitality. And while big brands make headlines, small and mid-sized organizations are often the most vulnerable, especially without the proper security infrastructure.

At Yeo & Yeo Technology, we’re helping Michigan-based businesses stay ahead of these threats with proactive security solutions and specialized guidance. Let’s examine the biggest ransomware attacks so far this year, the takeaways, and our advice on staying safe.

Top Ransomware Attacks Reported in 2025 (So Far)

1. MGM Resorts – $45 Million Fallout

Kicking off 2025, MGM agreed to a $45 million settlement for a ransomware attack that exposed the personal data of guests and employees in 2023. The attack stemmed from just one compromised employee account, highlighting how damaging one weak link can be.

Key Takeaway: Social engineering and credential theft remain top tactics. Companies must improve identity management and training.

2. Smiths Group – Manufacturing Systems Compromised

This UK-based manufacturer experienced a significant cybersecurity incident in January, which led to operational disruptions and unauthorized access to internal systems.

Key Takeaway: Operational technology (OT) is increasingly targeted. Manufacturers need layered defenses and better segmentation.

3. Big Cheese Studio – Game Code and Personal Data Held Hostage

Polish gaming company Big Cheese Studio was hit with ransomware that compromised source code and demanded payment in cryptocurrency. The attack also leaked employee data.

Key Takeaway: Intellectual property is a high-value target. Data loss prevention and backup strategies are essential.

4. NYC Hospital System – Patient Records Exposed

In March 2025, a major New York healthcare network was attacked, with over 1 million patient records accessed. The attackers exploited outdated software and poor patch management.

Key Takeaway: Healthcare organizations must prioritize updates and vulnerability management to protect sensitive data.

5. Midwest K-12 School District – Learning Halted for Days

A school district in the Midwest shut down for several days due to ransomware. Learning systems, payroll, and communication tools were all disrupted.

Key Takeaway: Public sector organizations need modern cybersecurity tools and incident response plans, even on tight budgets.
