Windows 8.1 Wanna Cry Patch

Microsoft issues ‘highly unusual’ Windows XP patch to prevent massive ransomware attack. But there are still organizations that continue to run Windows XP despite the risks. Microsoft is. A single point of Microsoft Windows patches for Wanna.Cry ransomware. I created this website as a single point for those who are trying to surf in the nightmare of Microsoft Update Catalog website and looking for patch their systems to protect from Wanna.Cry ransomware. Security Update for Windows XP SP2 for x64-based Systems. Given the potential impact to customers and their businesses, we made the decision to make the Security Update for platforms in custom support only, Windows XP, Windows 8, and Windows Server 2003, broadly available for download (see links below).

Microsoft just released a patch for Windows XP that fixes a file sharing flaw being exploited by the WannaCry ransomware. Here's how to install it.

You can download some versions of the patch using links at the bottom of this May 12th Microsoft article: Customer Guidance for WannaCrypt attacks. The full list of patch variants, including languages other than English, is in the Windows Catalog, just search for KB4012598.

For an x86 machine with Service Pack 3 installed, the downloaded file name is

windowsxp-kb4012598-x86-custom-enu_eceb7d5023bbb23c0dc633e46b9c2f14fa6ee9dd.exe

I know, its looks like malware itself. The file is small, only 665K. Logon as an Administrator and, for good luck, make a Restore Point first thing.

To see if System Restore is enabled, right click on My Computer, get the Properties and go to the System Restore tab. To actually make the Restore Point, go to Start -> Programs -> Accessories -> System Tools -> System Restore.

The installation process is simple.

1. Wizard warns you to backup your system and close all open programs
2. Then you have to agree to a license
3. Installing the patch takes only a few seconds, even on old hardware. It first asks you to wait while it 'inspects your current configuration, archives your current files and updates your files.' Then it makes a restore point.
4. When its all done, it wants you to reboot

After rebooting, you can verify that the patch was correctly installed using Add or Remove Programs in the Control Panel. You first need to turn on the checkbox to 'Show updates.' Then scroll down looking for the 'Windows XP - Software updates' section. It should be huge.

In this section, look for 'Security Update for Windows XP (KB4012598)' with the current date as the date installed (see above). Considering this is Windows XP, the installation date should stick out like a sore thumb. On two machines that I tested, it was, fortunately, the last entry in the list.

The fix applies to the file sharing component of Windows (Server Message Block or SMB) and thus prevents an XP machine from being infected over a LAN (Local Area Network). However, it would not protect an XP machine that was attacked another way, via email, for example.

I checked around (here and here) and Microsoft has not issued an update to their free anti-malware software, Security Essentials, for Windows XP. When XP went off support, it was denied access to Security Essentials. Thus, XP machines remain vulnerable to WannaCry, just not via file sharing on a LAN.

To fully protect an XP machine requires a third party antivirus product. Lotsa luck with that.

BitDefender bragged today that they can protect against WannaCry, but they do not support Windows XP (see below for update). Neither does Avira, Trend Micro or F-Secure. Kaspersky still supports XP, but their website says nothing about WannaCry.

So, yes, Microsoft released a patch for Windows XP. But now you know the rest of the story.

UPDATE: May 15, 2017. A reader was nice enough to point out that Bitdefender does offer a product that supports Windows XP (and Vista too). The name is fairly direct: Security for XP and Vista.

UPDATE: May 15, 2017. A couple people have told me that when they verified the installation of the patch, the install date was not the current date but tomorrows date. Beats me why.

Vulnerability Information

Multiple Windows SMB Remote Code Execution Vulnerabilities

Remote code execution vulnerabilities exist in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerabilities could gain the ability to execute code on the target server.

To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server.

The security update addresses the vulnerabilities by correcting how SMBv1 handles these specially crafted requests.

### Mitigating Factors Microsoft has not identified any [mitigating factors](https://technet.microsoft.com/library/security/dn848375.aspx) for these vulnerabilities. ### Workarounds The following [workarounds](https://technet.microsoft.com/library/security/dn848375.aspx) may be helpful in your situation: - **Disable SMBv1** **For customers running Windows Vista and later** See [Microsoft Knowledge Base Article 2696547](https://support.microsoft.com/kb/2696547). **Alternative method for customers running Windows 8.1 or Windows Server 2012 R2 and later** For client operating systems: 1. Open **Control Panel**, click **Programs**, and then click **Turn Windows features on or off.** 2. In the Windows Features window, clear the **SMB1.0/CIFS File Sharing Support** checkbox, and then click **OK** to close the window. 3. Restart the system. For server operating systems: 1. Open **Server Manager** and then click the **Manage** menu and select **Remove Roles and Features**. 2. In the Features window, clear the **SMB1.0/CIFS File Sharing Support** check box, and then click **OK** to close the window. 3. Restart the system. **Impact of workaround.** The SMBv1 protocol will be disabled on the target system. **How to undo the workaround.** Retrace the workaround steps, and select the **SMB1.0/CIFS File Sharing Support** check box to restore the SMB1.0/CIFS File Sharing Support feature to an active state. Windows SMB Information Disclosure Vulnerability – CVE-2017-0147 ---------------------------------------------------------------- An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server. To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server. The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests. The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability title	CVE number	Publicly disclosed	Exploited
Windows SMB Information Disclosure Vulnerability	[CVE-2017-0147](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2017-0147)	No	No
