Data breaches have become one of the most significant threats for businesses of all sizes, with 2024 already marked by several headline-grabbing incidents. Sensitive data—ranging from social security numbers and genetic information to millions of patient and student records—has been compromised, prompting organizations to rethink both their security tactics and their data privacy commitments. This guide offers critical insights into what businesses need to know about modern data breaches, how these incidents are evolving, and practical steps to mitigate risk.
Recent Breaches Making Headlines
Let’s start with a look at some of the most impactful data breaches and data privacy challenges of the past year:
- 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 breach occurred in December when an unauthorized third party gained access to a third-party software development platform used by the company. 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. LexisNexis disclosed the incident through a filing with Maine’s attorney general and sent notification letters to affected individuals, though some have criticized the company’s response timeline for the breach disclosure.

The breach targeted a company that maintained personal data for tens of millions of children, representing one of the more serious cybersecurity incidents affecting minors’ sensitive information. The case highlights the vulnerability of educational technology systems and the serious legal consequences faced by those who exploit these weaknesses to access protected student data.
Reference: Gizmodo on Facebook - 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 a change of ownership. The letters, signed by 20 Democratic members of Congress, were sent to Regeneron Pharmaceuticals and TTAM Research Institute, which have submitted separate bids to acquire the genetic testing company. Congressional representatives are specifically asking whether these potential buyers will continue to give customers the option to delete their data and withdraw consent for their information to be used in medical research, and whether 23andMe’s current policy of not sharing genetic data with law enforcement without a warrant will be maintained under new ownership.
Reference: Reddit - 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.
Reference: Fierce Biotech - 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.

Key Lessons for Businesses
The scale and persistent nature of these breaches illustrate that no industry is immune—from legal and analytics firms to healthcare and education. Several key takeaways emerge for business leaders and IT security professionals:
- Third-party risks are real: Both the LexisNexis breach and the 23andMe developments show that external vendors, partners, or acquirers can be a weak security link. Rigorous vetting, contractually enforced data privacy obligations, and periodic audits are essential.
- Prompt breach disclosure matters: Delays in public notification, as seen in the LexisNexis incident, can erode trust and invite regulatory scrutiny. Build redundancy into your breach detection, escalation, and communication flows.
- Privacy policies should evolve as your business does: The Congressional attention on 23andMe’s sale is a reminder that data handling policies must be robust and adaptable to corporate changes, especially mergers and acquisitions.
- Healthcare and education are prime targets: As shown by the breaches affecting patients and schoolchildren, organizations in these sectors face advanced persistent threats and must prioritize layered security and regulatory compliance.
- Legal and reputational consequences are escalating: The 19-year-old hacker’s prosecution demonstrates increased law enforcement focus on cybercrime. Fines and class-action lawsuits are also on the rise, so legal review and insurance (cyber liability) are smart steps.
How Businesses Can Prevent Data Breaches
While no solution can guarantee complete immunity from data breaches, there are actionable steps every business should implement as part of a cyber-resilience strategy:
- Implement robust access controls: Restrict access to sensitive data on a need-to-know basis, using multi-factor authentication where possible.
- Continuously monitor for threats: Deploy real-time monitoring, logging, and alerting systems to catch suspicious activity early. Learn more about how monitoring and observability support business security.
- Educate your workforce: Run regular training sessions to help employees recognize phishing, social engineering, and security best practices. Phishing simulations and updated security policies work best.
- Encrypt sensitive information: Both in-transit and at-rest encryption make data less valuable if stolen.
- Maintain and test incident response plans: Periodically simulate breach scenarios to test your team’s readiness and improve response protocols.
- Vet and monitor third parties: Use comprehensive vendor risk assessments and demand clear contractual clauses on breach notification, liability, and audit rights.
- Embrace a culture of compliance and improvement: Stay updated with changing regulations and evolving threats. See what a data breach means for your business.
