Lessons from the Biggest Data Breaches of 2024: Safeguarding Your Business in an Evolving Threat Landscape

2024 was a pivotal year in the cybersecurity landscape, marked by significant data breaches that sent shockwaves across industries. These incidents not only exposed sensitive information but also disrupted operations and eroded consumer trust. By examining these high-profile breaches, we can identify actionable lessons to strengthen your organization’s defenses. While these companies are not NTG clients, their experiences highlight the value of robust security measures—something we specialize in providing.

1. National Public Data Breach: The Imperative of Data Security

In April 2024, National Public Data (NPD), a data broker specializing in background checks, suffered a catastrophic breach. Hackers accessed approximately 2.9 billion records, including Social Security numbers, addresses, and dates of birth, affecting almost every American. This breach, attributed to inadequate security practices, resulted in lawsuits and the company’s eventual bankruptcy.

Lesson Learned: Implement Comprehensive Data Protection Measures

• Data Encryption: Ensure sensitive data is encrypted both at rest and in transit.
• Regular Security Audits: Conduct frequent security assessments to identify vulnerabilities.
• Access Controls: Limit data access to authorized personnel following the principle of least privilege.

2. AT&T Data Breach: The Necessity of Multi-Factor Authentication

AT&T experienced a breach where hackers accessed personal data of over 70 million customers, including Social Security numbers and account details. This attack stemmed from the absence of multi-factor authentication (MFA), a fundamental security measure.

Lesson Learned: Enforce Multi-Factor Authentication

• Mandatory MFA: Require MFA across all systems to add an extra security layer beyond passwords.
• User Education: Educate employees and customers about setting up and using MFA.
• Regular Updates: Keep authentication methods updated to counter evolving threats.

Change Healthcare, a major player in the healthcare industry, faced a breach that exposed medical records, insurance data, and financial information of over 100 million individuals. This breach disrupted payment and prescription processing nationwide.

Lesson Learned: Develop and Test Incident Response Plans

• Comprehensive Response Strategy: Outline roles, communication channels, and recovery procedures.
• Regular Drills: Conduct simulated cyberattack exercises to ensure preparedness.
• Stakeholder Communication: Maintain transparent communication with stakeholders to manage trust during incidents.

4. Snowflake Inc. Breach: Vigilance Against Credential Theft

Snowflake Inc. reported a breach in which login credentials for customer accounts were compromised through malware targeting accounts without MFA. This breach affected companies like Ticketmaster and AT&T.

• Operational Resilience: Maintain critical business functions during and after a cyberattack.

7. Rhode Island Data Breach: Ransomware Preparedness

In December 2024, Rhode Island faced a data breach targeting residents’ personal and financial information through ransomware. Hackers demanded payment to avoid data release.
