In the case of credential reflection attacks, inbound connections using the relayed credentials are most likely over the SMB or RPC services. Blocking TCP ports and at the firewall will help protect systems that are behind that firewall from attempts to exploit this vulnerability. Microsoft recommends that you block all unsolicited inbound communication from the Internet to help prevent attacks that may use other ports.

Impact of Workaround: Several Windows services use the affected ports. Blocking connectivity to the ports may cause various applications or services to not function. Some of the applications or services that could be impacted are listed below:.

Enabling SMB signing prevents the attacker from executing code in the context of the logged-on user. SMB signing provides mutual and message authentication by placing a digital signature into each SMB, which is then verified by both the client and the server. Computers that have this policy set will not communicate with computers that do not have client-side packet signing enabled. For more information on SMB signing and potential impacts, see Microsoft network server: Digitally sign communications always.

Mitigating Factors: In order to relay credentials, an attacker would need to successfully leverage another vulnerability to execute a man-in-the-middle attack, or to convince the victim, using social engineering, to connect to a server under the attacker's control, for instance by sending a link in a malicious e-mail message.

This reduces the risk that credentials can be forwarded or reflected by an attacker within this zone. Inbound traffic must be allowed to the client system for a reflection attack to succeed.

Advisory Status: Advisory published. Frequently Asked Questions What is the scope of the advisory? Forms of credential relaying referred to in this advisory are: Credential forwarding: domain credentials that are obtained by an attacker can be used to log on to other services that the victim is known to have access to. The attacker could then acquire permissions identical to that of the victim on the target service. The attacker would then acquire permissions on that machine identical to that of the victim. Upon connecting to this hostname, the client would consider this a local machine and attempt IWA credentials, thereby exposing these to the remote attacker; Microsoft has released several updates to help address these scenarios and this advisory aims to summarize how customers can best assess risk and issues in their specific deployment scenario.

UPDATE NOW! Critical, remote, ‘wormable’ Windows vulnerability

Microsoft has released the following security bulletins to address DNS spoofing attacks: MS addresses two vulnerabilities that could allow an attacker to spoof DNS records and insert them into the DNS server cache. MS addresses two vulnerabilities that could allow an attacker to spoof DNS records and insert them into the DNS server cache, and two vulnerabilities which could allow an attacker to maliciously register network infrastructure-related host names WPAD and ISATAP that could be used to accommodate further attacks.

This feature helps protect authentication attempts against relaying attacks. Review the Microsoft Knowledge Base Article that is associated with this advisory Customers who are interested in learning more about this security advisory should review Microsoft Knowledge Base Article Protect Your PC We continue to encourage customers to follow our Protect Your Computer guidance of enabling a firewall, getting software updates and installing antivirus software.

It provides a way to tightly restrict access to Remote Desktop ports while supporting remote connections through a single "Gateway" server. When using an RD Gateway server, all Remote Desktop services on your desktop and workstations should be restricted to only allow access only from the RD Gateway. There are many online documents for configuring this embedded Windows component.

Installing the configuring, the role service is mostly as described; however, using a Calnet issued trusted Comodo certificate is recommended. The Comodo cert is usually better accepted so that your end users do not receive certificate warnings. A rough estimate might be that concurrent users can use one RD Gateway. The HA at the virtual layer provides enough fault-tolerant and reliable access; however a slightly more sophisticated RD gateway implementation can be done with network load balancing.

Configuring your client to use your RD Gateway is simple. Using other components like VNC or PCAnywhere is not recommended because they may not log in a fashion that is auditable or protected. With RDP, logins are audited to the local security log, and often to the domain controller auditing system. When monitoring local security logs, look for anomalies in RDP sessions such as login attempts from the local Administrator account. Whenever possible, use GPOs or other Windows configuration management tools to ensure a consistent and secure RDP configuration across all your servers and desktops.

  • By enforcing the use of an RDP gateway, you also get a third level of auditing that is easier to read than combing through the domain controller logins and is separate from the target machine so it is not subject to tampering. This type of log can make it much easier to monitor how and when RDP is being used across all the devices in your environment. Departments with sensitive data should also consider using a two-factor authentication approach.

    That is beyond the scope of this article, but RD Gateways do provide a simple mechanism for controlling authentication via two-factor certificate based smartcards.

    Other two factor approaches need another approach at the Remote Desktop host itself, e. Highly motivated admins can also investigate the use Network Access Protection NAP with an RD Gateway, however, that technology and standard are not well developed or reliable yet. Skip to main content.
