Collaborating against ransomware: Insights from the Melissa Project
Ransomware stands as one of the most significant cyber threats of our time. Across the globe, organisations are facing increasingly sophisticated attacks that inflict substantial economic and societal damage.
In 2022, the ‘Melissa’ project was launched to strengthen the Netherlands’ digital resilience against ransomware-related crime. This initiative represents a collaboration between public and private sectors, including the National Cyber Security Centre (NCSC), the police, the Public Prosecution Service (OM), the Cyber Security Netherlands industry association, and leading cybersecurity firms.
An evaluation conducted by researchers at Leiden University offers valuable insights into the importance of such collaborations, the factors contributing to their success, and the challenges that have become apparent for the future.

Why the Melissa project Is essential
Prior to Melissa, much of the knowledge surrounding ransomware remained fragmented, hindering the effective sharing of technical, legal, and operational insights between public and private actors. Melissa consolidates this knowledge into a dedicated platform where data can be analysed and translated into collective actions. This approach not only strengthens the Netherlands’ digital resilience but also increases the risks for cybercriminals, making targets within the Netherlands less attractive.

Results: What Melissa has achieved
The Melissa Project demonstrates the potential of public-private collaboration. A notable success was the dismantling of the global Qakbot botnet, in which Dutch law enforcement agencies cooperated closely with international partners. This joint operation not only disrupted the functioning of Qakbot but also led to the identification of key individuals, facilitating legal prosecution.
In addition, Melissa has produced several white papers, addressing issues such as ransomware and data exfiltration. These publications provide practical guidance for organisations seeking to enhance their digital resilience and are widely utilised as educational material across sectors.

Success factors: The power of collaboration
The evaluation conducted by Bibi van den Berg, Daan Weggemans, and Melissa Nobbenhuis identifies several critical success factors underpinning the effectiveness of the Melissa Project. Public and private sectors bring unique knowledge and resources to the table, such as technical threat intelligence and legal expertise, enabling a comprehensive and multifaceted approach to ransomware threats. The integration of technical analyses with legal and operational expertise ensures that appropriate and timely actions can be taken.
Moreover, trust has proven to be a cornerstone of effective collaboration. Regular meetings and informal contacts foster close communication, enhancing the willingness to share crucial information. The shared motivation to contribute to a safer and more resilient digital society serves as a key driving force behind the success of the project.
Prof. Dr. Bibi van den Berg: ‘Collaborating both formally and informally within a relatively fixed group fosters mutual trust.’
Challenges and opportunities for the future
Despite the successes achieved, several challenges remain. A significant concern is the reliance on the voluntary allocation of resources, which poses a risk to the long-term continuity of the initiative.
Furthermore, legal and ethical challenges surrounding information sharing persist. Striking a careful balance between maintaining confidentiality and ensuring effective collaboration will require ongoing attention. Developing clear and robust guidelines for information exchange is essential in addressing these issues.
Looking ahead, the researchers recommend the sustainable professionalisation of collaborative structures. It is crucial to strengthen these frameworks while preserving the flexibility and openness that underpin their success. Exploring opportunities to connect with other national and international initiatives will further enhance the Netherlands’ position in the global fight against cybercrime.
Collaboration as the key to combating ransomware
The Melissa Project illustrates the power of public-private collaboration in combating ransomware. Successful actions against ransomware groups and the development of knowledge products highlight the importance of a collective approach. Through effective information sharing and joint action, the impact of our defensive measures can be significantly enhanced, enabling us to manage cyber threats more effectively.
The lessons learned from Melissa are not only relevant for addressing ransomware but also provide valuable insights for other forms of collaboration in the digital domain. By further strengthening such partnerships, the Netherlands can better equip itself against future cyberattacks.
What is ransomware?
Ransomware is a type of malicious software that encrypts files on a computer, network, or server system, rendering users unable to access their data. Criminals then demand a ransom, often in cryptocurrency, in exchange for restoring access. Ransomware typically spreads through phishing emails, infected websites, or vulnerabilities in software.
The impact of ransomware attacks is significant: they can paralyse organisations, result in the loss of critical data, and cause substantial financial and societal damage. As these criminal activities become increasingly sophisticated, collaboration between public and private parties is essential to pool knowledge, strengthen preventive measures, and respond effectively to incidents.
