Overview
The Microsoft Digital Defense Report 2024 provides a comprehensive picture of the current cybersecurity landscape. In his introduction, Tom Burt emphasizes that the cyber threat environment continues to become more dangerous and complex. The malicious actors are becoming better resourced and prepared, with increasingly sophisticated tactics, techniques, and tools that challenge even the world’s best cybersecurity defenders.
Microsoft’s customers face more than 600 million cybercriminal and nation-state attacks every day. The stakes are particularly high in healthcare, where 389 healthcare institutions were successfully hit by ransomware in the US alone this fiscal year, resulting in network closures, systems offline, and delayed medical operations.
Microsoft’s unique vantage point comes from processing more than 78 trillion security signals per day, from billions of Windows endpoints, cloud services, and a broad spectrum of products and services. This provides visibility into attack activity and emerging attack techniques. The company employs 34,000 full-time dedicated security engineers and works with 15,000 partners with specialized security expertise.
A significant development in 2024 was the Secure Future Initiative (SFI), which is Microsoft’s response to significant attacks on their corporate infrastructure. The initiative orchestrates a company-wide effort to make security their top corporate priority, including eliminating 730,000 non-compliant apps and 5.75 million inactive tenants to reduce the potential cyberattack surface.
The company’s commitment to cybersecurity and organizational resilience is reflected in its approach to transparency and information sharing. The insights derived from their unique vantage point are shared through this report as part of their commitment to helping the world understand and mitigate cyber threats.
The Evolving Cyber Threat Landscape
The report identifies several key developments in the cyber threat landscape. Nation-state actors and cybercriminals are increasingly blurring the lines between their activities. Nation-state threat actors are conducting operations for financial gain and enlisting cybercriminals to collect intelligence.
North Korean hackers have stolen over $3 billion in cryptocurrency since 2017, with heists totaling between $600 million and $1 billion in 2023 alone. These stolen funds reportedly finance over half of North Korea’s nuclear and missile programs.
Ransomware remains a critical concern, with a 2.75x increase year over year in human-operated ransomware-linked encounters. However, the percentage of attacks reaching actual encryption phase has decreased threefold over the past two years, partly due to automatic attack disruption.
The report highlights the rise of sophisticated AI-enabled human targeting. These threats will be more difficult to detect and defend against—even with AI tools assisting defensive strategies. Emerging techniques include AI-enabled spear phishing, “résumé swarming” (where AI generates hundreds of fake job applications), and increasingly sophisticated deepfakes.
Identity attacks continue to pose a significant threat, with over 600 million attacks per day. As multifactor authentication blocks most password-based attacks, threat actors are shifting their focus to more sophisticated methods such as adversary-in-the-middle (AiTM) attacks.
Centering Organizations on Security
The report emphasizes the responsibility of organizations to maintain robust accountability alongside fundamental mastery of cybersecurity essentials. Microsoft’s Secure Future Initiative serves as a model for how organizations can approach security transformation.
A key focus is on data security, particularly in light of the growing use of generative AI. Organizations must implement sufficient data governance controls to prevent data exposure through AI applications. The report introduces a “hierarchy of cybersecurity needs,” starting with the basic need to protect identities against ransomware and supply chain attacks.
The report reveals that 80% of organizations have attack paths that expose critical assets. This highlights the importance of taking a threat-informed approach to defense. Organizations must understand their critical assets and crucially how they are, or could be, connected.
Best practices for robust cybersecurity governance and accountability are outlined, emphasizing that everyone in the organization, including Board members, must have basic literacy of cybersecurity threats, a sense of personal responsibility for security, and clarity on their role.
Critical infrastructure environments receive special attention, with detailed analysis of operational technology (OT) security. The report shares findings from testing OT applications in Microsoft’s data centers, providing valuable insights for the broader industry about securing these crucial systems.
Early Insights: AI’s Impact on Cybersecurity
The report provides comprehensive analysis of how AI is reshaping the cybersecurity landscape. While AI provides defenders with powerful tools to preempt and counteract evolving threats with unprecedented precision, it also presents new challenges.
Nation-state threat actors are increasingly using AI for influence operations. The report details how actors from Russia, Iran, and China are using AI-generated images and audio manipulations to shape audience perception and engagement in conspiratorial narratives.
However, the report emphasizes that AI holds significant potential for defense. Defenders are using AI to become more efficient, especially in security operations. Microsoft’s research shows that novice users were able to perform 26% faster and were 44% more accurate across all tasks when using AI-powered security tools.
The report also discusses how governments and industries are working to advance global AI security. While there is a consensus on the importance of security in the development of AI, governments have pursued different approaches in implementing security requirements. The report outlines various collaborative policy initiatives and international standards being developed to ensure responsible AI development and deployment.
Looking ahead, the report suggests that staying ahead of threat actors in the age of AI will require a combination of technological innovation and policy principles. Organizations must be early adopters of AI defensive tools while also maintaining robust security fundamentals.
