Here are a few details. <\/p>\n<p><!--more--><\/p>\n<h2>SMBv1 30 years old and unsecure<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/ssl-vg03.met.vgwort.de\/na\/c3531b3871fb457fb45e1a8a0fe4edf1\" width=\"1\" height=\"1\"><a href=\"https:\/\/en.wikipedia.org\/wiki\/Server_Message_Block\" target=\"_blank\" rel=\"noopener\">SMB<\/a> stands for Server Message Block (also known as LAN-Manager or NetBIOS protocol) has been used as a network protocol for file, printer and other server services. SMBv1 has been designed more than 30 years ago and Microsoft's implementation is categorized as deprecated. <\/p>\n<p>Since Windows Vista there are SMBv2 and later, SMBv3 has been introduced. So SMBv1 isn't necessary in Windows networks. <\/p>\n<h2>This fall SMBv1 shall be deactivated<\/h2>\n<p>Ned Pyle from Microsoft has published <a href=\"https:\/\/blogs.technet.microsoft.com\/filecab\/2017\/06\/01\/smb1-product-clearinghouse\/\" target=\"_blank\" rel=\"noopener\">this blog post<\/a> on June 1, 2017, where he enlists products from other vendors still using SMBv1. At the end of this blog post, Pyle mentions the end of SMBv1 for Microsoft Windows.<\/p>\n<blockquote>\n<p>For more information on why using SMB1 is unsafe, see <a href=\"https:\/\/aka.ms\/StopUsingSMB1\" target=\"_blank\" rel=\"noopener\">StopUsingSMB1<\/a>. SMB1 has been deprecated for years and will be removed by default from many editions and SKUs of Windows 10 and Windows Server 2016 in the RS3 release.<\/p>\n<\/blockquote>\n<p>RS3 means Windows 10 Fall Creators Update (Version 1709), expected in September\/October 2017. Microsoft runs internally some test builds of Windows 10 Enterprise and Windows Server 2016 with SMBv1 deactivated. <\/p>\n<p>Microsoft decided to retire SMBv1 five years ago (long before WannaCry malware used unpatched vulnerabilities in SMBv1). Ned Pyle told <a href=\"https:\/\/web.archive.org\/web\/20220807040318\/https:\/\/www.bleepingcomputer.com\/news\/microsoft\/microsoft-to-disable-smbv1-in-windows-starting-this-fall\/\" target=\"_blank\" rel=\"noopener\">Bleeping Computer<\/a> some more Details. <\/p>\n<blockquote>\n<p>That date is now the release of Windows 10 Redstone 3, also referenced as the Fall Creators Update, scheduled for launch in October\/November 2017.  <\/p>\n<p>After that day, every new Windows 10 or Windows Server 2016 OS you install will not have some or all of SMBv1 turned on, which is the norm right now.  <\/p>\n<p>This is not patching, nor upgrading, This is clean install RS3<\/p>\n<\/blockquote>\n<p>So, only clean installs will see SMBv1 deactivated by default. Already running systems are untouched concerning SMBv1. <\/p>\n<h2>How to deactivate SMBv1?<\/h2>\n<p>If you intend to deactivate the deprecated SMBv1 in your Windows environment, this is possible.
