Hacktivist Exploitation of Mercenary Spyware in Western Europe

Introduction

In recent years, the landscape of cyber threats in Western Europe has evolved, with hacktivist groups increasingly exploiting mercenary spyware and collaborating with exploit brokers. This trend poses a medium-level threat to regional cybersecurity, necessitating a comprehensive understanding of the actors, tools, and tactics involved.

Hacktivist Groups and Their Motivations

Hacktivist groups are politically motivated entities that use cyberattacks to promote their ideological objectives. In Western Europe, several such groups have emerged, often aligning with broader geopolitical interests. For instance, the pro-Russian hacktivist collective NoName057(16) has been active since March 2022, targeting government and private sector entities across NATO member states and other European countries perceived as adversarial to Russian interests. Their operations have included Distributed Denial of Service (DDoS) attacks and data breaches, primarily aimed at silencing organizations deemed anti-Russian. (helpnetsecurity.com)

Mercenary Spyware and Exploit Brokers

Mercenary spyware refers to surveillance tools developed by private companies and sold to government clients, often for intelligence and law enforcement purposes. However, these tools have been misused to target journalists, activists, and political figures. A notable example is the use of Paragon's Graphite spyware against Italian journalists and human rights defenders in 2025. The spyware was found to have infected WhatsApp accounts of individuals critical of the Italian government's policies toward migrants. (washingtonpost.com)

Exploit brokers play a crucial role in the cyber threat ecosystem by discovering and selling zero-day vulnerabilities—previously unknown flaws in software that can be exploited by attackers. In February 2026, the U.S. Department of the Treasury imposed sanctions on Sergey Zelenyuk and his firm, Operation Zero, for trafficking in cyber exploits used to gain unauthorized access to information systems. This incident underscores the significant threat posed by exploit brokers in facilitating cyberattacks. (cyberpress.org)

Commercial Offensive Tools and Red Team Frameworks

Commercial offensive tools and red team frameworks are legitimate resources used by organizations to test and enhance their cybersecurity defenses. However, when misused, they can be weaponized by malicious actors. The proliferation of such tools has been linked to state permissive behaviors, where governments may turn a blind eye to the activities of private surveillance companies. This permissiveness contributes to the proliferation of offensive cyber tools and services, which can be misused to violate human rights and pose risks to international security. (rusi.org)

Surveillance-as-a-Service and Its Implications

The concept of surveillance-as-a-service involves the outsourcing of surveillance capabilities to private companies that offer these services to government clients. This model has raised concerns about accountability and oversight, as it can lead to the deployment of surveillance tools without adequate checks and balances. The use of such services by hacktivist groups, especially when targeting individuals and organizations within Western Europe, highlights the need for robust cybersecurity measures and legal frameworks to protect civil liberties.

Conclusion

The intersection of hacktivist activities, mercenary spyware, and exploit brokers presents a complex and evolving threat landscape in Western Europe. While the threat level is currently assessed as medium, the potential for escalation remains significant. It is imperative for governments, private sector entities, and civil society organizations to collaborate in enhancing cybersecurity defenses, ensuring legal compliance, and upholding human rights in the face of these emerging challenges.

Recommendations

• Enhanced Monitoring and Detection: Implement advanced monitoring systems to detect unauthorized surveillance activities and the use of exploit tools.

• Legislative Measures: Develop and enforce laws that regulate the sale and use of surveillance technologies, ensuring they are not misused by unauthorized actors.

• International Cooperation: Foster international collaboration to share intelligence on cyber threats and coordinate responses to transnational cyber incidents.

• Public Awareness: Educate the public and organizations about the risks associated with mercenary spyware and the importance of cybersecurity hygiene.

By proactively addressing these areas, stakeholders can mitigate the risks associated with hacktivist exploitation of mercenary spyware and strengthen the overall cybersecurity posture of Western Europe.
