Ransomware encrypted Windows machine\u2019s files, and then used a remote vulnerability found in outdated SMB versions (SMBv1 and SMBv2) to distribute itself to other Windows machines on the same network. Ransomware spread at an estimated rate 5 million infected emails per hour, targeting home users to corporate networks.<\/p><p>In hindsight, the current ransomware disaster could have been avoided. For many years Microsoft has been pleading with customers to end using the old and vulnerable SMB1 protocol and upgrade to the encrypted SMB version. In his <a href=\"https:\/\/techcommunity.microsoft.com\/t5\/storage-at-microsoft\/stop-using-smb1\/ba-p\/425858\" target=\"_blank\" rel=\"noopener\">blog post<\/a>, Ned Pyle, Microsoft Principal Program Manager, has explained the SMB1 security vulnerabilities and the lack of efficiency.<\/p><p>A similar warning had come on March 16, 2017 from the Department of Homeland <a href=\"https:\/\/www.cisa.gov\/uscert\/ncas\/current-activity\/2017\/01\/16\/SMB-Security-Best-Practices\" target=\"_blank\" rel=\"noopener\">Security in a security best practice article<\/a>, which had advised users and administrators to disable the SMB1 protocol completely due to its security vulnerability.<\/p><p>Further to the above, Kaspersky Labs has <a href=\"https:\/\/securelist.com\/wannacry-ransomware-used-in-widespread-attacks-all-over-the-world\/78351\/\" target=\"_blank\" rel=\"noopener\">reported<\/a> that SMB2 is also a source of the latest Ransomware cyber-attacks.<\/p><p>The best way to ensure that your customer\u2019s or your environment stays protected is to deploy the encrypted SMB3.1.1 protocol.<\/p><p><strong>As a company dedicated to advancing the latest SMB protocols, Visuality Systems offers the NQ Family of products that support the latest encrypted SMB3.1.1 protocol for all operating systems under a commercial
