Cyber espionage is primarily conducted to obtain sensitive or classified information, trade secrets, or other types of intellectual property (IP) that can provide the aggressor with a competitive edge or be sold for financial profit. In some cases, the objective of the breach is to damage the victim’s reputation by disclosing private information or questionable business practices.

Although cyber espionage attacks can be driven by financial incentives, they may also be executed in conjunction with military operations or as acts of cyber terrorism or cyber warfare. The effects of cyber espionage, particularly when part of a larger military or political agenda, can lead to disruptions in public services and infrastructure, as well as loss of life.

Cyber Espionage Targets

The most frequent targets of cyber espionage are large corporations, government agencies, academic institutions, think tanks, and other organizations that hold valuable intellectual property (IP) and technical data that could provide a competitive advantage to another organization or government. Targeted campaigns may also focus on individuals, including prominent political leaders, government officials, business executives, and even celebrities.

Cyber spies typically aim to access the following types of assets:

  • Research and development data and activities
  • Academic research data
  • Intellectual property, such as product formulas or blueprints
  • Salaries, bonus structures, and other sensitive financial information related to organizations’ finances and expenditures
  • Client or customer lists and payment structures
  • Business objectives, strategic plans, and marketing strategies
  • Political strategies, affiliations, and communications
  • Military intelligence

Common Cyber Espionage Tactics

Most cyber espionage activities are classified as advanced persistent threats (APTs). An APT refers to a sophisticated, prolonged cyberattack in which an intruder establishes an undetected presence within a network to steal sensitive data over an extended period. These attacks are meticulously planned to infiltrate a specific organization and evade existing security measures for long durations.

Carrying out an APT attack demands a higher level of customization and sophistication compared to traditional attacks. Adversaries are usually well-funded, experienced teams of cybercriminals that target high-value organizations. They invest considerable time and resources in researching and identifying vulnerabilities within the organization.

Most cyber espionage attacks also incorporate some form of social engineering to prompt actions or gather necessary information from the target to facilitate the attack. These tactics often exploit human emotions such as excitement, curiosity, empathy, or fear, causing victims to act quickly or rashly. As a result, cybercriminals deceive their victims into divulging personal information, clicking on malicious links, downloading malware, or paying a ransom.

Other common attack techniques include:

  • Watering hole: Malicious actors infect legitimate websites frequently visited by the victim or individuals associated with the target with malware to compromise the user.
  • Spear-phishing: Hackers target specific individuals with fraudulent emails, texts, and phone calls to steal login credentials or other sensitive information.
  • Zero-day exploits: Cybercriminals exploit unknown security vulnerabilities or software flaws before they are discovered and patched by the software developer or the customer’s IT team.
  • Inside actors or insider threats: A threat actor persuades an employee or contractor to share or sell information or grant access to the system to unauthorized users.

Global Impact of Cyber Espionage

Cyber espionage, especially when orchestrated by nation-states, is an increasing security threat. Despite numerous indictments and legislative measures designed to curb such activities, many criminals remain at large due to the absence of extradition agreements between countries and the difficulties in enforcing international law regarding this issue.

This challenge, combined with the growing sophistication of cybercriminals and hackers, leaves the door open for coordinated and advanced attacks that could disrupt various modern services, including the electricity grid, financial markets, and major elections.

Cyber Espionage Penalties

Although many countries have issued indictments for cyber espionage activities, the most significant cases often involve foreign actors in countries without extradition agreements. Consequently, law enforcement agencies have limited ability to pursue cybercriminals, especially those operating outside their borders.

However, the investigative groundwork used to support these cyber espionage indictments can also serve as a foundation for imposing sanctions on a foreign country or company. For instance, in the U.S., the Department of the Treasury can utilize investigative materials from indictments to impose economic sanctions against a corporation known to be involved in cyber espionage activities.

Real-World Examples of Cyber Espionage

While some cyber spies operate legitimately within the intelligence community, the most well-known instances tend to have more sinister motivations. Here are some notable examples of cyber espionage in action:

Aurora

One of the most infamous cyber espionage breaches occurred in 2009. Google initially reported a series of attacks targeting specific Gmail accounts, later identified as belonging to Chinese human rights activists. Following this revelation, other major companies, including Adobe and Yahoo, confirmed they too had experienced similar attacks. Ultimately, 20 companies acknowledged being affected by this cyber espionage incident, which exploited a vulnerability in Internet Explorer. This security flaw has since been resolved.

COVID-19 Research

More recently, cyber espionage efforts have concentrated on research related to the COVID-19 pandemic. Since April 2020, intrusion activities aimed at coronavirus research have been reported against laboratories in the U.S., U.K., Spain, South Korea, Japan, and Australia, with involvement from Russian, Iranian, Chinese, and North Korean actors.

For instance, in the latter half of 2020, CrowdStrike uncovered a targeted intrusion against an academic institution involved in developing COVID-19 testing capabilities. The malicious activity was attributed to Chinese hackers, who gained initial access through a successful SQL injection attack on a vulnerable web server. Once inside the victim’s environment, the actor deployed a web shell to conduct various malicious activities primarily focused on gathering and collecting information.

Nation-State Actors

As mentioned earlier, many of the most sophisticated cyber espionage campaigns are orchestrated by well-funded, state-sponsored threat actor teams. Notable nation-state actors and recognized cyber espionage groups include:

  • PIONEER KITTEN: An Iran-based hacking group active since at least 2017, suspected to have ties to the Iranian government. In late July 2020, an actor believed to be associated with PIONEER KITTEN was reported to be advertising access to compromised networks on an underground forum, indicating a possible shift towards revenue generation alongside targeted intrusions for the Iranian government.
  • FANCY BEAR (APT28, Sofacy): Operating since at least 2008, this Russia-based group uses phishing messages and spoofed websites that closely mimic legitimate ones to gain access to conventional computers and mobile devices. It has targeted U.S. political organizations, European military entities, and victims across various sectors worldwide.
  • GOBLIN PANDA (APT27): First detected in September 2013 by CrowdStrike, this China-based cyber espionage group utilized two Microsoft Word exploit documents with training-related themes to deploy malicious files upon opening. Their targets primarily include the defense, energy, and government sectors in Southeast Asia, especially Vietnam.
  • HELIX KITTEN (APT34): Active since at least late 2015, this likely Iran-based group targets organizations in aerospace, energy, finance, government, hospitality, and telecommunications. They employ well-researched and structured spear-phishing messages relevant to the targeted personnel, commonly delivering a custom PowerShell implant via macro-enabled Microsoft Office documents.

Cyber Espionage Detection, Prevention and Remediation

The increasing sophistication of cyber attackers and spies has allowed them to evade many standard cybersecurity products and legacy systems. While these adversaries often utilize advanced techniques and complex tools, defending against such attacks remains achievable. Numerous cybersecurity and intelligence solutions are available to help organizations better understand these threat actors, their attack methods, and the tactics they typically employ.

  • Sensor Coverage: Effective defense begins with visibility. Organizations should implement solutions that provide comprehensive visibility across their environment to eliminate blind spots that adversaries could exploit.
