The WannaCry ransomware has proven so malicious that Microsoft is patching Windows versions dating back as far as 14 years. Microsoft says it decided to patch the outdated systems “with the.

All you need to know about WannaCrypt in 60 seconds

Microsoft has taken the unprecedented step of issuing patches for unsupported operating systems - like Windows XP - in the wake of the massive WannaCrypt ransomware attacks against organisations across the globe.

Businesses, governments and individuals in 74 countries across the globe have been victims of more than 45,000 attacks by this one strain of ransomware in the space of just a few hours.

Everything you need to know about ransomware: how it started, why it's booming, how to protect against it, and what to do if your PC is infected.

Wannacrypt ransomware demands $300 in Bitcoin for unlocking encrypted files - a price which doubles after three days. Users are also threatened with having all their files permanently deleted if the ransom isn't paid in a week.

Hospitals across the UK have had systems knocked offline by the ransomware attack, with patient appointments cancelled and doctors and nurses resorting to pen and paper and NHS England declaring the cyberattack as a 'major incident' - a total of 45 NHS organisations are now own to be affected.

Cybersecurity researchers have suggested the ransomware attacks are so potent because they exploit a a known software flaw dubbed EternalBlue. This Windows flaw is one of many zero-days which apparently was known by the NSA -- before being leaked by the Shadow Brokers hacking collective. Microsoft released a patch for the vulnerability earlier this year - but only for the most recent operating systems.

One thing many of the targets have in common is that they're running old Windows operating systems like Windows XP, Windows 8 and Windows Server 2003, which now only usually receive patches if the organisation using them are receiving special custom support.

However, in order to ensure as many systems as possible are protected against WannaCrypt ransomware and other attacks, Microsoft has made security patches for Windows XP and other operating systems broadly available to download.

'This decision was made based on an assessment of this situation, with the principle of protecting our customer ecosystem overall, firmly in mind,' the company told customers in a blog post.

Customers can now download security updates for Windows Server 2003 SP2 x64, Windows Server 2003 SP2 x86,Windows XP SP2 x64, Windows XP SP3 x86, Windows XP Embedded SP3 x86, Windows 8 x86, and Windows 8 x64.

Microsoft is continuing to work with customers to provide assistance as the situation evolves.

In response to the attacks against the UK's National Health Service, Home Secretary Amber Rudd is set to chair an emergency Cobra crisis-committee meeting to coordinate a government response to the incident.

Meanwhile,. The National Cyber Security Centre has issued a statement to say it is 'working round the clock with UK and international partners and with private sector experts to lead the response to these cyber attacks'.

Ciaran Martin, CEO of the National Cyber Security Centre, said that in order to protect against this sort of attack, organisations should 'make sure your security software patches are up to date' and 'make sure that you are running proper anti-virus software'

Security Update for Microsoft Windows SMB Server (4013389)

Published: March 14, 2017

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker sends specially crafted messages to a Microsoft Server Message Block 1.0 (SMBv1) server.

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software and Vulnerability Severity Ratings section.

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

For more information about the vulnerabilities, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 4013389.

Affected Software and Vulnerability Severity Ratings

The following software versions or editions are affected. Versions or editions that are not listed are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, see Microsoft Support Lifecycle.

The severity ratings indicated for each affected software assume the potential maximum impact of the vulnerability. For information regarding the likelihood, within 30 days of this security bulletin’s release, of the exploitability of the vulnerability in relation to its severity rating and security impact, please see the Exploitability Index in the March bulletin summary.

Note Please see the Security Update Guide for a new approach to consuming the security update information. You can customize your views and create affected software spreadsheets, as well as download data via a restful API. For more information, please see the Security Updates Guide FAQ. As a reminder, the Security Updates Guide will be replacing security bulletins. Please see our blog post, Furthering our commitment to security updates, for more details.

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.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

### 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.
