Ransomware Threats Surge in February 2025: A Comprehensive Analysis

Ransomware attacks continue to evolve, and understanding these evolving threats is critical for both organizations and individuals to stay protected. In this monthly Bitdefender Threat Debrief, we examine ransomware activities from February 2025, revealing an alarming 126% increase in victims compared to the previous year. This surge marks a historic high in ransomware-related claims, making it one of the most severe months in cybersecurity history. This report delves into the factors behind the spike, analyzes tactics used by threat actors, and offers valuable insights into how to defend against these growing threats.

February 2025 Ransomware Threat Summary:

In February 2025, ransomware claimed a record 962 victims, a staggering 126% increase from the 425 victims reported in February 2024. This surge represents the highest number of claimed victims in ransomware history. A significant contributor to this surge was the Clop (Cl0p) group, which claimed responsibility for 335 attacks—a 300% increase compared to the previous month.

The reason for this dramatic rise in ransomware incidents lies in the increasing opportunism among threat groups. Cybercriminals are now exploiting newly discovered vulnerabilities in network devices, particularly in software flaws that can be quickly automated and exploited for remote access. This trend has made it easier for ransomware groups to scale their attacks and target a larger number of organizations.

One of the most notable examples of this trend was Clop’s exploitation of vulnerabilities in Cleo file transfer software (CVE-2024-50623 and CVE-2024-55956). These vulnerabilities, disclosed in late 2024, allowed attackers to run malicious commands on compromised systems. Although these flaws were identified months ago, the manual process of exploiting them took time, leading to the late surge in attacks. Clop’s success highlights the broader threat landscape where ransomware groups target software vulnerabilities instead of focusing on individual industries.

As cybercriminals adapt their techniques, they now prioritize vulnerabilities that allow quick exploitation. They initiate automated scans soon after a vulnerability is disclosed, establishing remote access to affected systems. This quick exploitation is followed by manual efforts to deepen the attack, often taking weeks or months before the actual ransomware deployment or data theft occurs.

What Undercode Says:

The surge in ransomware activity is not just a trend—it’s an alarming evolution of cybercrime tactics. Over the past few years, ransomware groups have consistently adapted, shifting their strategies to maximize impact and minimize detection. The data from February 2025 indicates that ransomware is no longer just a method of targeting high-profile companies. Instead, the focus has shifted to opportunistic attacks on vulnerabilities in software and hardware that can be exploited rapidly.

This shift to targeting network devices and exposed vulnerabilities is a strategy that reflects the changing landscape of cybersecurity threats. These attacks leverage the speed and scale of automation, allowing even smaller, less sophisticated groups to carry out large-scale attacks. Furthermore, the increased use of “living off the land” techniques, where attackers rely on legitimate system tools to evade detection, is a growing concern. These techniques make it much harder to spot and mitigate threats early on, which has significant implications for organizations’ cybersecurity strategies.

Moreover, groups like Clop are taking advantage of critical vulnerabilities like the ones found in Cleo software, demonstrating the importance of timely patching and vulnerability management. The ability to manually hack into systems after initial access is a key part of the new ransomware playbook. This highlights the necessity for both reactive and proactive defenses, including continuous vulnerability scanning, employee training, and strong access controls.

Another aspect of the growing threat landscape is the emergence of ransomware-as-a-service (RaaS) platforms. RaaS allows less skilled attackers to rent ransomware tools, making the threat even more widespread. This democratization of ransomware, coupled with the rise of automated attacks targeting system vulnerabilities, suggests that smaller groups may become just as dangerous as more established players.

Additionally, the use of AI and other advanced technologies by ransomware groups, as seen with FunkSec, is worth noting. These developments not only enhance their capabilities but also raise the stakes for defenders, who must now contend with more sophisticated, agile, and well-funded adversaries.

Fact Checker Results:

The statistics provided by Bitdefender, such as the 126% year-over-year increase in ransomware victims, have been consistent with other industry reports.
The claim that Clop’s attacks were facilitated by exploiting specific vulnerabilities is supported by multiple independent cybersecurity sources, confirming the growing trend of automated attacks.
However, some of the specific financial impacts of these attacks are difficult to verify, as ransomware gangs often inflate their claims for effect.

Conclusion:

The rise in ransomware activity during February 2025 is a stark reminder of the evolving nature of cyber threats. As attackers continue to refine their tactics and exploit newly discovered vulnerabilities, organizations must remain vigilant. Timely patching, robust cybersecurity strategies, and continuous monitoring will be key to defending against the growing ransomware threat.
