ITRC Annual Data Breach Report 2024

Keypoints

• The typical annual cybersecurity report is structured into main sections such as Introduction, Glossary, At-a-Glance Summary, Executive Summary, Analysis, Solutions, Resources, and Appendices, providing a comprehensive overview of breach data, trends, and mitigation strategies.
• Key statistics include 3,158 data compromises in 2024, nearly matching previous records, with over 1.3 billion victim notices—primarily driven by five mega-breaches, making up about 83% of all breach notices.
• Major threats continue from cyberattacks, especially supply chain and zero-day vulnerabilities, although fewer breaches are linked directly to zero-day exploits this year. Attack vectors often lack detailed reporting, with 70% of breach notices omitting root cause information.
• Notable industry trends show financial services now suffer the highest number of compromises, followed by healthcare and professional services, emphasizing sector-specific attack growth.
• Recurring themes include the inadequacy of disclosure regulations to prevent breaches, the growing impact of mega-breaches on public perception, and the promising role of passkeys in eliminating credential theft.
• Insights reveal that many breaches could have been prevented via basic cybersecurity practices like multi-factor authentication and proper cloud security configurations, highlighting areas for organizations to improve defenses.
• Comprehensive reports often emphasize the importance of adopting new technology solutions, such as passkeys, and advocating for stronger privacy laws to effectively reduce the frequency and impact of data breaches.
