Mercenary Spyware and the Commercial Offensive Cyber Market in Western Europe

Introduction

The landscape of cyber threats in Western Europe has evolved significantly, with advanced persistent threat (APT) groups increasingly adopting mercenary spyware and commercial offensive tools. These technologies, often developed by private entities and sold to government clients, have been instrumental in sophisticated cyber espionage campaigns targeting both state and non-state actors.

Proliferation of Mercenary Spyware

Mercenary spyware refers to surveillance tools developed by private companies and sold to government agencies for intelligence and law enforcement purposes. Notable examples include NSO Group's Pegasus, Candiru's DevilsTongue, and Cytrox's Predator. These tools exploit zero-day vulnerabilities to gain unauthorized access to target devices, enabling the interception of communications, location tracking, and data exfiltration.

In 2025, the Italian government acknowledged the use of Predator spyware against opposition politicians and critical journalists, highlighting the growing concern over the deployment of such tools within Europe. (journals.sagepub.com)

Exploit Brokers and Commercial Offensive Tools

Exploit brokers act as intermediaries, facilitating the sale and distribution of zero-day vulnerabilities and exploit tools. Their activities have significantly contributed to the proliferation of commercial offensive tools. For instance, the leak of the Coruna exploit kit, a sophisticated iOS exploit framework, demonstrated how nation-state-grade tools can transition from surveillance vendors to financially motivated cybercriminals.

Red Team Frameworks and Surveillance-as-a-Service

Red team frameworks are tools and methodologies used by security professionals to simulate adversarial attacks, assessing the resilience of systems and networks. However, the commercialization of these frameworks has led to their adoption by APT groups for offensive operations. The availability of surveillance-as-a-service platforms has further democratized access to advanced cyber capabilities, enabling even less-resourced actors to conduct sophisticated surveillance and cyber espionage activities.

Implications for Western Europe

The integration of mercenary spyware and commercial offensive tools by APT groups poses several challenges:

• Escalation of Cyber Espionage: The availability of advanced surveillance tools has intensified cyber espionage activities, targeting governmental institutions, critical infrastructure, and private enterprises.

• Erosion of Privacy: The deployment of such tools raises significant concerns regarding individual privacy rights, as they can be used to monitor communications and activities without consent.

• Regulatory Challenges: The rapid proliferation of these tools has outpaced regulatory frameworks, complicating efforts to establish effective oversight and control mechanisms.

Conclusion

The convergence of mercenary spyware, exploit brokers, and commercial offensive tools has transformed the cyber threat landscape in Western Europe. APT groups' adoption of these technologies underscores the need for enhanced vigilance, robust cybersecurity measures, and comprehensive regulatory approaches to mitigate the risks associated with this evolving threat.
