Critical Flaws in Windows NTLM Protocol

Jul 12, 2017·Dustin

Estimated Reading Time: 1 min

This Patch Tuesday from Microsoft includes patches for Windows that affects all Windows OS’s released since 2007. Swati Khandelwal has a post about the new vulnerabilities and how they could be exploited. Make sure you run Windows Update to grab the latest updates and protect yourself from these vulnerabilities.

Researchers at behavioral firewall specialist Preempt discovered two zero-day vulnerabilities in Windows NTLM security protocols, both of which allow attackers to create a new domain administrator account and get control of the entire domain.

NT LAN Manager (NTLM) is an old authentication protocol used on networks that include systems running the Windows operating system and stand-alone systems.

Although NTLM was replaced by Kerberos in Windows 2000 that adds greater security to systems on a network, NTLM is still supported by Microsoft and continues to be used widely.
