Insights from ENISA's 2024 Ransomware Landscape

Insights from ENISA’s 2024 Ransomware Landscape

Ransomware remains one of the most pressing cybersecurity threats in 2024. According to the recently published ENISA Threat Landscape 2024 report by the European Union Agency for Cybersecurity (ENISA), ransomware attacks have grown more sophisticated, targeting organizations across industries with alarming frequency. As a Backup as a Service (BaaS) provider, we recognize the critical role of secure, automated backups in mitigating ransomware risks. In this article, we delve into key findings from the report, focusing on ransomware trends, incidents across Europe, and practical mitigation strategies outlined in Annex B.

The Ransomware Threat

The ENISA report identifies ransomware as a dominant threat, evolving in complexity and impact. Among the notable trends are:

1. Double and Triple Extortion: Cybercriminals no longer rely solely on encrypting files. Many now threaten to leak sensitive data if ransoms are not paid, with some escalating to contacting customers or stakeholders of the victim organization.

2. Targeting SMBs: While large enterprises often make headlines, small and medium-sized businesses (SMBs) have become a primary target due to their perceived lack of robust defenses. For SMBs, a successful attack can be catastrophic.

3. Geopolitical Drivers: Ransomware campaigns increasingly intersect with geopolitical tensions. State-sponsored actors are believed to leverage ransomware to destabilize critical infrastructure or exert economic pressure on adversaries.

These trends highlight the growing sophistication of attackers and their relentless pursuit of vulnerabilities within organizations, regardless of size or industry.

European Ransomware Landscape

The ENISA report provides striking statistics about ransomware incidents across Europe. Over the past quarters, ransomware attacks have surged by over 25%, with sectors such as healthcare, education, and local governments being disproportionately affected. Notable incidents include:

• Healthcare Organizations: Critical healthcare services in multiple European nations were disrupted by ransomware, delaying medical procedures and compromising patient data.
• Municipal Governments: Local authorities faced operational shutdowns as attackers exploited legacy systems with insufficient cybersecurity measures.

For example, among European nations, France, Germany, and Spain were the most heavily targeted by the ransomware group Lockbit, experiencing frequent attacks on industries ranging from manufacturing to public services.

This data underscores the urgency for European organizations to bolster their ransomware defenses, particularly in sectors handling sensitive data and essential services.

Why Backups Are Key in Ransomware Mitigation

A robust backup strategy is one of the most effective defenses against ransomware. Here’s why:

1. Minimizing Data Loss: Automated backups ensure that even if an organization’s primary systems are compromised, data can be restored to a point before the attack.

2. Reducing Downtime: Ransomware often forces organizations to halt operations while addressing the breach. With reliable backups, recovery can be swift, minimizing disruptions.

3. Avoiding Ransom Payments: Backups eliminate the need to pay ransoms, which not only saves money but also reduces funding for criminal enterprises.

Organizations must adopt best practices, such as the 3-2-1 backup rule: keep three copies of data, stored on two different media, with one copy kept offsite and offline. Moreover, immutability—ensuring backups cannot be altered or deleted—adds an extra layer of protection.

Mitigation Strategies from Annex B

Annex B of the ENISA Threat Landscape 2024 report outlines actionable recommendations for mitigating ransomware risks. The first one related to ransomware and backups mentions:

Implement a secure and redundant backup strategy. Ensure you maintain offline, encrypted data backups that are regularly tested, following your backup procedures.

Implemented by security measures from international standards i.e. ISO/IEC 27001:2022620 or NIST Cybersecurity Framework (CSF) v2.0:

ISO/IEC 27001:2022

• A5.30 ICT readiness for business continuity
• A8.13 Information backup
• A8.14 Redundancy of information processing facilities

NIST Cybersecurity Framework (CSF)

• PR.DS-11 Backups of data are created, protected, maintained, and tested
• RC.RP-03 The integrity of backups and other restoration assets is verified before using them for restoration
• PR.IR-04 Adequate resource capacity to ensure availability is maintained
• PR.DS-10 The confidentiality, integrity, and availability of data-in-use are protected

By adopting these recommendations, organizations can significantly reduce their vulnerability to ransomware and improve resilience against attacks.
