In 2025, ransomware continues to be one of the most persistent and dangerous cyber threats, constantly evolving in both complexity and impact. Although significant progress has been made in the field of IT security, organizations-regardless of size or industry-are still the target of increasingly sophisticated attacks. One of the most worrying recent tendencies is the appearance of so-called EDR Killers-malware specially designed to deactivate endpoint detection and response (EDR) before launching a ransomware attack itself. According to ESET experts, this confirms the quick ability to adapt the attackers to the new security measures, exploiting the vulnerabilities existing in the infrastructure of the companies.
For more up-to-date information and recommendations on ransomware protection, ESET-Cyber Security Company no. 1 of the European Union – offers free a dedicated guide.
Financial and strategic motivations behind ransomware attacks
Ransomware is powered not only by financial interests, but also by tactical or strategic objectives of the apt groups sponsored by the states. In this complex context, prevention becomes an essential element in the cyber defense strategy. Although rapid intervention and post-incident recovery are important, the most effective solution is to block the attack before it is materialized.
In a climate of permanent transformation threats, the ability of organizations to anticipate, detect and neutralize ransomware attacks is more important than ever. This involves the use of advanced technologies, capable of acting continuously – 24/7, throughout the year.
Lessons of 2024: Disappearance Lockbit and Ascension Ransomhub
A reference moment in 2024 was the elimination of the Lockbit group, considered the global leader of the RAAS (Ransomware-As-Service). His disappearance created a significant vid in the ransomware ecosystem, immediately occupied by the Ransomhub group, which quickly managed to become dominant.
So far, Ransomhub has targeted a broad spectrum of industries – from IT, public and governmental services, to health, nutrition, finance, production and communications. Their success is based on advanced methods of compromising networks, operating vulnerabilities, recruiting affiliates of former Lockbit or Blackcat groups and offering an attractive reward system, as well as access to their own EDR Killer.
The stages of an attack: Prevention begins early
Ransomware represents, in fact, the final stage of a complex cyber attack. Most of the time, it is preceded by actions such as phishing, vulnerability, gross force attacks, using stolen credentials or personalized malware. Many of these attacks can be detected and stopped in the early stages – the moment when protection is the most effective.
An effective strategy involves a multistratified security approach, which includes automation, artificial intelligence and permanent monitoring. This proactive approach is already adopted by an increasing number of companies aware of increased risks.

Ransomware in 2025: adaptable, sophisticated, dangerous
Ransomware remains in 2025 an active, constantly transforming threat, and the dynamics around groups like Lockbit and Ransomhub highlight how quickly things can be changed in this ecosystem. In the face of this context, organizations must adopt solid preventive measures, based on stratified security and advanced technologies.
ESET offers state -of -the -art digital security solutions, developed to anticipate and prevent computer attacks before they become real. The new functionality Ransomware Remediationintegrated into ESET solutions, is an owner technology that helps in the automatic restoration of encrypted files if the ransomware is detected in a subsequent stage of the attack, after the encryption process has already started. ESET security solutions are available at any time for free download and test and can be requested here.
By integrating human expertise with the power of artificial intelligence, ESET remains in the forefront of protection against emerging and already known cyber threats, ensuring the security of companies, critical infrastructures and individual users. Regardless of the type of protection required-endpoint, cloud or mobile-cloud-fired solutions, based on AI are both effective and easy to use. In completing real-time defense, 24/7, ESET also offers efficient localized support (including in Romania), actively engaging in researching the latest threats through its own R&D centers, including the one in Iași, and through an extended global network.
