- May 13, 2017 Microsoft issues ‘highly unusual’ Windows XP patch to prevent massive ransomware attack. New, 80 comments. This includes specific fixes for Windows XP, Windows 8.
In a rare step, Microsoft published a patch for Windows XP, Windows Server 2003 and Windows 8—all of them operating systems for which it no longer provides mainstream support.
Users can download and find more information about the patches in Microsoft’s blog post about Friday’s attack from the WannaCry ransomware.

A download to the security patch released by Microsoft for the 'WannaCrypt' attacks is available for versions of Windows that do not receive mainstream support. Wannacry patches for 2003/XP Available. Search in Spiceworks How To Wanna Cry.
The ransomware, which has spread globally, has been infecting computers by exploiting a Windows vulnerability involving the Server Message Block protocol, a file-sharing feature.
Computers infected with WannaCry will have their data encrypted, and display a ransom note demanding $300 or $600 in bitcoin to free the files.
Fortunately, Windows 10 customers were not targeted in Friday’s attack. In March, Microsoft patched the vulnerability that the ransomware exploits—but only for newer Windows systems. That’s left older Windows machines, or those users who failed to patch newer machines, vulnerable to Friday’s attack.
Researchers originally believed the ransomware was spread through attachments in email phishing campaigns. That no longer appears to be the case.
Once a vulnerable PC becomes infected, the computer will attempt to spread to other machines over the local network as well as over the internet. The ransomware will specifically scan for unpatched machines that have the Server Message Block vulnerability exposed.
Businesses can prevent this by disabling the Server Message Block protocol in vulnerable PCs. They can also use a firewall to block unrecognized internet traffic from accessing the networking ports the Server Message Block uses.
Fortunately, Friday’s ransomware attack may have been contained. A security researcher who goes by the name MalwareTech has activated a sort of kill-switch in WannaCry that stops it from spreading.
As a result, over 100,000 new infections were prevented, according to U.K.’s National Cyber Security Centre. But experts also warn that WannaCry’s developers may be working on other versions that won’t be easy to disable.

“It’s very important everyone understands that all they (the hackers) need to do is change some code and start again. Patch your systems now!” MalwareTech tweeted.
Unfortunately, the kill-switch’s activation will provide no relief to existing victims. The ransomware will persist on systems already infected.
Friday’s ransomware attack appears to have spread mainly in Europe and Asia, with Russia among those nations hardest hit, according to security researchers.
Security experts are advising victims to wait before paying the ransom. It’s possible that researchers will develop a free solution that can remove the infection.

Microsoft has released security updates for several unsupported versions of Microsoft Windows, including Windows XP, to block WannaCrypt ransomware attacks.
The ransomware WannaCrypt has been making the rounds in May 2017: it infects Windows machines, encrypts files, asks for ransomware, and spreads like a worm.
Microsoft published detailed information on the vulnerability on the new Malware Protection Center blog. According to the information, the attackers exploit te 'recently' patched SMB EternalBlue vulnerability which sends custom packets to SMBv1 servers. Microsoft released patches for all supported versions of Windows on the March 2017 patch day.
While Microsoft did release patches for supported versions of Windows, it appears that the attackers did target Windows 7, Windows Server 2008 and earlier versions of Windows only.

The exploit code used by WannaCrypt was designed to work only against unpatched Windows 7 and Windows Server 2008 (or earlier OS) systems, so Windows 10 PCs are not affected by this attack.
In a surprising move, Microsoft released security patches for unsupported versions of the Windows operating system that patch the SMB vulnerability on devices running these versions of Windows as well.
Security Bulletin MS17-010 describes the security update that you may apply to unsupported versions of Windows as well now.
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.
Microsoft has not found evidence of the entry vector, but thinks the following two scenarios are highly possible
- Arrival through social engineering emails designed to trick users to run the malware and activate the worm-spreading functionality with the SMB exploi
- Infection through SMB exploit when an unpatched computer can be addressed in other infected machines“
Microsoft released security updates for the following versions of Windows:
- Windows XP, Windows Vista, Windows 8
- Windows Server 2003, 2008, Windows XP Embedded
Administrators and users may download updates for affected operating systems from the Microsoft Update Catalog. Another option that administrators have is to disable the SMB functionality on machines to block exploits from targeting these systems successfully.
Unsupported versions of Windows have a sizable market share still. While stats are not 100% accurate, Net Market Share sees Windows XP at a market share of about 7% in April 2017, and Vista at about 0.70%. This means that every 14th or so device runs an unsupported client version of Windows. It is unclear how the situation looks like for Server operating systems.

Still, Microsoft's release of the patch ensures that companies, and home users, may patch their devices to protect them against the attack. One effect of patching systems is that this will also prevent the security threat from spreading faster or further.

We also know that some of our customers are running versions of Windows that no longer receive mainstream support. That means those customers will not have received the above mentioned Security Update released in March. 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.
