Few threats in today’s digital world are as persistent—or as potentially damaging—as data breaches. As sensitive information migrates onto cloud platforms and interconnected databases, attackers continually innovate, targeting everything from social security numbers to genetic data. In this article, we’ll dissect some of the most significant recent data breaches, analyze what went wrong, and provide actionable strategies to defend your organization’s digital infrastructure.
Major Data Breaches: Recent Case Studies
LexisNexis leaked social security numbers and other personal data for over 364,000 people
LexisNexis Risk Solutions, a data analytics firm, suffered a significant data breach that exposed the personal information of over 364,000 people. The cyberattack occurred in December when an unauthorized third party gained access to the company’s records through a third-party software development platform. The compromised data included highly sensitive information such as Social Security numbers, full names, contact information, and driver’s license numbers of 364,333 individuals. The breach represents a major security incident for the data broker company, and affected individuals have been notified through official letters from LexisNexis about the unauthorized access to their personal data.

19-Year-Old to Plead Guilty to Hacking Charges After Data Breach of Millions of Schoolchildren
A 19-year-old Massachusetts college student named Matthew Lane has pleaded guilty to hacking charges related to a major data breach affecting PowerSchool, a company that manages educational data for millions of students and teachers. Lane and unidentified co-conspirators were involved in multiple cybercrimes, including stealing data from a telecommunications company in May 2024 and demanding $200,000 in bitcoin ransom. The case escalated significantly when PowerSchool’s system was breached in September 2024, ultimately leading to a ransom demand of approximately $2.85 million in bitcoin on December 28, 2024, with threats to release personal information of about 60 million students and 10 million teachers worldwide. The breach particularly impacted North Carolina public school students and teachers, exposing sensitive personal data of current and former students in the state’s educational system.

Congress Demands Answers on Data Privacy Ahead of 23andMe Sale
House Democrats have sent letters to potential buyers of 23andMe, demanding answers about how they plan to protect customer genetic data under new ownership. The letters, signed by 20 Democratic members of Congress, were sent to Regeneron Pharmaceuticals and TTAM Research Institute, both of which have submitted separate bids to acquire the genetic testing company. The congressional inquiry specifically asks whether the potential buyers will maintain customers’ ability to delete their data and withdraw consent for medical research use, and whether they will uphold 23andMe’s current policy of not sharing genetic data with law enforcement without a warrant. This congressional action reflects growing concerns about the protection of sensitive genetic information as the company undergoes a potential change in ownership.

23andMe (and Your Genetic Data) Sold to Regeneron in Bankruptcy Auction
23andMe has been sold to Regeneron Pharmaceuticals for $256 million following a bankruptcy auction, with Regeneron submitting the highest bid for substantially all of the genetic testing company’s assets. The acquisition includes 23andMe’s biobank containing genetic samples from approximately 15 million customers, and Regeneron plans to operate 23andMe as a subsidiary while continuing to offer consumer genetic testing services. The deal is expected to close in the third quarter of 2025, and Regeneron has stated it will incorporate 23andMe’s genetic data findings into its own research operations. To address privacy concerns, Regeneron has committed to detailing its intended use of customer data and implementing privacy programs and security controls that will be reviewed by a court-appointed independent Customer Privacy Ombudsman and other interested parties.

Analysis & Insights: Key Trends and Lessons Learned
Analyzing the incidents above, several common themes emerge. Data breaches are not confined to any one sector—legal, education, healthcare, and biotechnology are all targets. Third-party software vulnerabilities, insider threats, and lack of stringent access controls continue to be major attack vectors. The shift toward leveraging cloud-based and SaaS platforms brings new risks, requiring comprehensive data governance strategies and regular auditing.
- Comprehensive Incident Response: Organizations must have robust response plans in place to minimize the fallout. For actionable guidance, check this primer on IT response to data breaches.
- Proactive Security Education: Continuous security awareness and education are non-negotiable as seen in incidents involving both technical vulnerabilities and human error.
- Vendor and Third-Party Management: Many breaches originate from third parties. Conduct regular vendor risk assessments and ensure contractual cybersecurity obligations are in place.
- Advanced Data Privacy Controls: With regulatory attention and high-profile breaches, privacy-by-design is essential. Encryption, data minimization, and clear consent mechanisms are a must.
Essential Strategies to Protect Your Digital Infrastructure
- Regular Security Audits: Systematic penetration testing and vulnerability management help uncover weak points before attackers do.
- Data Segmentation & Least Privilege: Limit access to sensitive information wherever possible. For businesses adapting to evolving threats, understand the fundamentals of data breach prevention.
- Endpoint Security & Monitoring: Monitor networks for suspicious activity using SIEM platforms, and deploy endpoint protection solutions.
- Resilience Through Backups: Ensure business continuity by regularly backing up critical systems and testing disaster recovery procedures.
