A Brief History of Threat Intelligence: How We Got Here 

Although cyber threat intelligence has become increasingly important in the modern era, driven by the exponential rise in cybercrime and global dependence on digital infrastructure, the foundational concept of threat intelligence is not a recent development. In 2024, just over four in ten businesses (43%) and three in ten charities (30%) reported experiencing some form of cybersecurity breach or attack in the previous 12 months, highlighting the scale of today’s threat landscape. Historically, intelligence gathering has played a crucial role in national security, particularly during war and political instability. In this blog, we explore the evolution of threat intelligence, from its origins in traditional military and espionage practices to the complex, data-driven field of cyber threat intelligence that organisations rely on today. 

Origins of Threat Intelligence 

Threat intelligence, as defined by Gartner, is evidence-based knowledge, such as context, indicators, and actionable insights, that helps organisations respond effectively to existing or emerging threats. While often associated with today’s digital landscape, its origins can be traced back to the early use of intelligence in military and geopolitical contexts. The foundations of cyber threat intelligence specifically began to form during the late stages of the Second World War and into the Cold War, as early computer prototypes emerged and cyberspace gradually became a key domain for intelligence operations.  

One of the first recorded cases of cyber espionage occurred in 1968, when an East German spy attempted to steal data from IBM’s German headquarters. As early as the 1960s, various actors were already attempting to compromise or steal sensitive data, prompting the introduction of fundamental security measures like administrator privileges, hashed passwords, access rights, and encryption, setting the stage for the evolution of threat intelligence in the cyber realm. 

One major milestone in the evolution of cyber threat intelligence was the development of encryption standards. Originating from IBM, the symmetric-key algorithm eventually became the Digital Encryption Standard (DES), later adopted and slightly modified by the NSA. This marked the agency’s growing role in government computer data security, expanding from its original focus on communications intelligence. 

Rise of Networked Systems and Data Vulnerabilities 

During the 1980s and 1990s, computer networks became commercialised and publicly accessible, leading to a surge in data production and the involvement of a wider range of actors. As a result, new threats and vulnerabilities emerged, exposing information systems to both remote attacks and insider threats. The NSA began testing the idea of a unified database to enable intelligence analysts across the U.S. Intelligence Community to share data more efficiently. Although the attempt failed, it marked an early recognition of the need for collaborative intelligence. This period also highlighted a critical shift: computer data was not only at risk of being stolen but could also be altered to compromise government systems. Ensuring data integrity thus became a key concern during the Cold War era. 

Post-Cold War Intelligence Operations 

In the aftermath of the Cold War, the concept of penetrating adversarial systems, stealing data, and disrupting command and control systems began to emerge within military operations. Many computerised systems storing valuable data became prime targets. While intelligence agencies like MI5, FSB, and the FBI had developed expertise in counterintelligence and surveillance, intelligence during this time was still primarily focused on traditional methods: HUMINT (Human Intelligence), SIGINT (Signals Intelligence), and IMINT (Image Intelligence). Cyber intelligence, however, was in its infancy, with little to no focus on gathering information in cyberspace. This shift would come in the following decades as the significance of cyber intelligence for national security grew.  

The Evolution of Modern Cyber Threat Intelligence 

As the internet and digital infrastructure have expanded, so too needs more sophisticated and proactive threat intelligence strategies. From its origins in military espionage to its early days in cyber espionage and data protection, threat intelligence has continuously evolved. Today, organisations face complex, dynamic threats in the form of cyberattacks that are increasingly hard to detect and mitigate. The importance of cyber threat intelligence cannot be overstated, as it empowers organisations to stay ahead of adversaries, anticipate attacks, and protect valuable digital assets. 

In conclusion, the history of threat intelligence is a testament to how the digital age has reshaped traditional intelligence methods. With cyber threats becoming more sophisticated, the future of threat intelligence will likely involve even more advanced technologies, such as artificial intelligence and machine learning, to provide real-time insights and more effective responses to emerging threats. Organisations must continue to adapt and embrace these evolving practices to safeguard their digital futures.
