👉 As ransomware continues to evolve in speed and complexity, traditional endpoint protection mechanisms often fall short, especially in environments with limited client-side defense.
👉 At present, ransomware remains one of the most prevalent forms of cybercrime worldwide. Due to its rapid proliferation and continuous technological advances, it is important to introduce conceptual changes in defensive strategies, develop new security mechanisms, and implement multi-factor detection systems.
👉 Recent threat intelligence consistently confirms the continued prominence of ransomware as a major cyber threat.
1️⃣ The ENISA Threat Landscape 2024 identifies ransomware among the most disruptive attack types.
2️⃣ the Verizon DBIR 2025 reports its involvement in 44% of confirmed breaches.
3️⃣ Sector-specific analyzes, such as the ENISA Finance Threat Landscape 2024, highlight its persistent impact across critical industries.
4️⃣ Europol’s Inter net Organized Crime Threat Assessment (IOCTA) likewise identifies ransomware as one of the most prominent and disruptive forms of cybercrime in recent years.
👉 Currently, there are many antivirus solutions and endpoint protection technologies available. However, in many cases these can be bypassed or disabled, which makes the success of an attack more likely.
1️⃣ As such malware primarily encrypts data and renders it inaccessible, the day-to-day functioning of organizations can be partially or completely disrupted during the restoration process. To minimize the damage, it is crucial to detect such attacks as early as possible.
2️⃣ For example, the LockBit malware was observed to encrypt 53.83 GB of data (100,000 files) across different MS Windows workstations in 4 min and 9 s, corresponding to an average speed of 216.18 MB/s.
3️⃣ These figures clearly highlight that rapid, preferably near real-time detection is essential for effective protection.
4️⃣ The targeted data assets are typically stored centrally and accessed by clients, often via network shares.
6️⃣ Client-side protection is generally considered less reliable, server-side file operation logs provide direct and trustworthy information on the performed activities.
7️⃣ Server-side monitoring can also serve as a basis for attack detection. Ransomware families tend to create, rename, and delete files with varying frequency, depending on their type.
🔶 A properly designed and implemented logging system, these characteristic operation sequences can be detected at fine temporal granularity.
