Windows Remains Vulnerable To Serious 18-Year-Old SMB Security Flaw
Mark Wilson writes A serious security hole leaves millions of Windows users open to attack, making it possible to extract encrypted credentials from a target machine. Researchers at Cylance say the problem affects "any Windows PC, tablet or server" (including Windows 10) and is a slight progression of the Redirect to SMB attack discovered by Aaron Spangler way back in 1997. Redirect to SMB is essentially a man-in-the-middle attack which involves taking control of a network connection. As the name suggests, victims are then redirected to a malicious SMB server which can extract usernames, domains and passwords. Cylance also reports that software from companies such as Adobe, Oracle and Symantec — including security and antivirus tools — are affected.

How hard is it to mandate any submission contain the source instead of some shill article?
The article states "the encryption method used was devised in 1998 and is weak by today’s standards ... Microsoft has yet to release a patch to fix the Redirect to SMB vulnerability" as if Microsoft must remove the feature in order for Cylance to consider this resolved. Instead a number of improvements have been made to SMB since 1998 include support for HMAC-SHA256 (v2.0) and AES-CMAC (v3.0) hashing. http://www.windowsecurity.com/.... You are going need a little more than "$3000 worth of GPUs" to forward brute force the AES-CMAC hashed passwords.
