But what makes the attack so unusually virulent is how it exploits a vulnerability in the Windows SMB protocol. SMB is used by Windows machines for sharing files and the ransomware uses SMB to spread to other vulnerable devices on a network. Once installed, the ransomware encrypts the files on the machine.

Like WannaCry, NotPetya leverages the SMB protocol to move laterally across the network, an EternalBlue exploit attributed to the National Security Agency (NSA) and leaked by the Shadow Brokers hacking group last April. The machine is then forced to reboot, encrypting the files and locking the computer. A total of 3.8

Using machine learning algorithms and the deep network insight of the Cato SASE Cloud , were able to detect and prevent the spread of ransomware across networks without having to deploy endpoint agents. As you might have heard, Cato introduced network-based ransomware protection today.

This blog post will explain the four main areas of impact of ransomware on organizations, and how Cato SASE Cloud can help prevent ransomware and protect businesses. Data Encryption According to Cybercrime Magazine, the global cost of ransomware damages will exceed $20 billion in 2021 and $265 Billion by 2031.

The POC was able to generate the so called Blue Screen of Death on Windows clients that connects into a compromised SMB server. Vulnerabilities in SMB servers should be treated very seriously. If attackers compromise an SMB server in the organization, they can exploit SMB vulnerabilities as part of wider lateral movement.

Executive Summary Modern ransomware attacks have evolved beyond simple encryption to deploy sophisticated double extortion tactics. Threat actors now systematically exfiltrate sensitive data before encrypting systems, ensuring leverage even when victims have robust data backups. GreenCollector tool (identified as fs256.exe)

Double Extortion: Double extortion ransomware both steals and encrypts sensitive and valuable data on an infected system. Lateral Movement: Ransomware rarely immediately lands on a device containing the high-value data that it plans to encrypt. Monitoring time intervals, such as encrypting drives in seconds.
