The rise of nation-state cyber attacks has become a defining feature of modern geopolitics. With blurred lines between advanced persistent threats (APTs) and cybercrime, understanding this complex landscape has become a critical element in building a strong cybersecurity strategy. According to recent reports on the rise of state-sponsored cyber attacks, nation-state actors targeting critical infrastructures have doubled from 20% to 40% in the past two years alone. As for the costs? Organizations are estimating a total of $1.6 million per cyber incident.
Not only is the frequency and financial consequences of such attacks accelerating, the threat landscape in which these nation-state actors now operate is also shifting. Cyber warfare and the use of cyberweapons in the ongoing Russo-Ukrainian war, for example, have magnified the intersection between conflict across both geopolitical and digital surfaces.
The challenge is that nation-state threat actors are well-funded and possess specialized skills, focusing their attacks on high-value targets including government and military entities, think tanks, universities, and those providing critical infrastructure services.
This post explores how nation-state sponsored attacks have evolved over recent years to become a threat not just to individual targets but to all organizations, as well as to the civil, economic and political fabric of our society. Sharing our collective knowledge on how such groups operate and the impacts they have can help the cyber defense community better understand and mitigate these sophisticated threats.
A Shadowy Threat | A Brief History of Cyber Espionage & Nation-State Attacks
Cyber espionage, a stealthy practice dating back to the very beginnings of internet connectivity, has undergone substantial changes in recent years, fueled by rapid advancements in technology and evolving global dynamics.
The origins of cyber espionage trace back to the 1980s when the French intelligence agency, led by the “Farewell Dossier”, exploited a KGB officer’s computer to gather critical information on Soviet activities. At the same time, a German hacker group known as the Chaos Computer Club exposed vulnerabilities in government and military systems. These incidents marked the inception of digital espionage and highlighted the potential of exploiting interconnected networks to gather intelligence. These early instances foreshadowed the evolution of cyber espionage into a formidable global concern in the decades that followed.
Cyber espionage has since evolved into a potent tool for nation-state threat actors and a critical security issue for organizations, with implications sounding across political, economic, and societal domains.
Subsequently, state-sponsored hacking campaigns, corporate espionage, and intellectual property (IP) theft have become rampant, with the potential to disrupt critical service industries and compromise national security. The interconnected nature of the modern world amplifies this impact as a breach in one corner of the globe can trigger far-reaching consequences.
As nations, corporations, and civilians have become increasingly reliant on digital infrastructure, the stakes have escalated, making targeted, state-sponsored cyber attacks a top-tier and global security concern. To safeguard against this escalating threat, international cooperation, robust cybersecurity measures, and innovative defense strategies are crucial in this new era of digital spycraft.
The Big Players | Navigating The Complex Landscape of APTs
By some estimates, there could be over a hundred different APT groups worldwide, but when we look at where most activity that threatens our interests originates from, there are four major nation-states that have been in the game longer than the rest.
Between them, China, Russia, North Korea and Iran have developed some of the most sophisticated and comprehensive threat activity and cyber tradecraft that businesses in all sectors have to face today.
China
China’s cyber threat is not only broad and persistent but also evolving. The Office of the Director of National Intelligence’s 2023 Annual Threat Assessment paints a clear picture of the cyber threat posed by the People’s Republic of China (PRC), noting that:
The annual report contains a stark warning.
Emerging in the early 2000s, Chinese-based threat groups rapidly matured in terms of tactics, techniques, and targets. The infamous Titan Rain campaign of the mid-2000s marked a watershed moment, exposing China’s cyber capabilities as it targeted U.S. defense and technology sectors. This trend continued with APT1, linked to the Chinese military, launching widespread attacks on various industries.
As time progressed, the Chinese cyber espionage ecosystem diversified. From 2006 to the present day, APT10 (aka Red Apollo/Stone Panda) has been reported targeting a wide-range of companies across multiple continents, including healthcare, defense, aerospace and government sectors. APT17 (DeputyDog) is a threat group sponsored by the Jinan bureau of the Chinese Ministry of State Security. First seen in 2009, it was attributed for the Operation Aurora and CCleaner supply chain attacks in 2017. APT41 (aka Winnti Group) was first seen in 2012 and combines financially-motivated cybercrime with information theft and espionage.
In general, Chinese APT groups have been known to use tactics like living-off-the-land (LOTL), where they abuse native tools like PowerShell and WMI to evade detection, and to develop comprehensive programs for vulnerability research and exploitation.
Most recently, Chinese threat groups are known to be disguising traffic to malicious servers through botnets of compromised IoT devices and to use DNS, HTTP and TCP/IP hijacking. Security researchers have found that Chinese threat groups tend to focus on security, networking and virtualization tools to obtain and maintain stealthy access to targeted organizations’ internal networks.
