LexisNexis Risk Solutions suffered a significant data breach that exposed the personal information of over 364,000 people, including names, Social Security numbers, driver’s license numbers, and contact information. The breach occurred in December when an unauthorized third party accessed the company’s records through a third-party platform used for software development. LexisNexis, which operates as a data analytics and data broker firm, filed notice of the incident with Maine’s attorney general, confirming that the compromised data included highly sensitive personal information that could potentially be used for identity theft and other fraudulent activities.

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. Lane and unidentified co-conspirators were involved in hacking PowerSchool’s system, facilitating a September 2024 data breach that compromised the personal information of approximately 60 million students and 10 million teachers worldwide. The hackers initially stole data from a telecommunications company in May 2024, demanding $200,000 in bitcoin, but later escalated their demands to about $2.85 million in bitcoin on December 28th, threatening to release the massive trove of educational data if their ransom demands were not met. This breach represents one of the largest compromises of student and teacher data in recent history, affecting millions of current and former students, including those in North Carolina’s public school system.
More details | Gizmodo update - 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.
Reddit discussion | Wired article - 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.
FierceBiotech coverage - Over 8M patient records leaked in healthcare data breach
Over 8 million patient records were exposed in a recent healthcare data breach, highlighting the ongoing vulnerability of medical information in the digital age. Healthcare data has become one of the most targeted types of information by cybercriminals over the past decade, with attackers focusing on various players in the healthcare ecosystem including insurance companies, medical clinics, and other healthcare providers that handle sensitive patient information. This breach represents a significant security incident that affects millions of individuals whose personal medical data may now be compromised, underscoring the critical need for enhanced cybersecurity measures across the healthcare industry to protect patient privacy and sensitive medical records from unauthorized access.

Analysis: The Ongoing Battle Against Data Breaches
Each of these breaches signals a serious challenge faced not just by global corporations, but by the IT teams, CISOs, and individual users relying on digital services every day. The LexisNexis attack, for instance, was enabled by a third-party software development platform—a critical reminder that software supply chains are often the weakest link, no matter how robust a company’s perimeter defences are. In the educational sector, the PowerSchool breach illustrates the immense scale of risk when student and faculty records are not sufficiently protected, and the escalation to ransom demands signals a trend other industries must guard against. Meanwhile, 23andMe’s acquisition drama underscores that even the world’s most sensitive data—such as genetic information—can become a business asset to be bought, sold, or mishandled.
Best Practices to Mitigate Data Breach Risks
- Comprehensive Vendor Risk Management: Audit not just your own systems but those of your vendors. Implement third-party risk assessments and require proof of security practices.
- End-to-End Encryption: Adopt modern encryption standards for all stored and transmitted data, ensuring sensitive data is useless if stolen.
- Zero Trust Security Model: Don’t implicitly trust any device, user, or network; instead, apply continuous verification throughout your IT ecosystem.
- Regular Security Awareness Training: Empower teams by simulating phishing, ransomware, and social engineering attacks. Human error is often the root cause of breaches.
- Incident Response Preparedness: Maintain and rehearse a rigorous, up-to-date incident response plan. Rapid containment, communication, and recovery make a difference.
- Data Minimization and Retention: Retain only essential data, regularly review data stores, and securely erase unnecessary information.
- Proactive Monitoring & Observability: Employ advanced monitoring and observability solutions to detect abnormal activity early on. Explore how observability supports breach detection.

Conclusion: Vigilance and Adaptability are the Best Defences
No company or sector is immune to the risk of a data breach. But with rigorous security hygiene, ongoing monitoring, collaborative vendor screening, and an organization-wide security mindset, the odds of catastrophic breach diminish. As illustrated by the recent cases, it’s critical to stay vigilant and embrace adaptable defence strategies if you want to keep your data—whether business, client, or personal—safe in this interconnected era.
