Today, Microsoft has released an update KB4012598 for Windows devices to fix WannaCry ransomware. The new update is now available for Windows XP, Windows 8 and Windows Server 2003. Previously, the company had released WannaCry ransomware patch for Windows 10 devices in Match. It resolved the problem for Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, and Windows Server 2016.

Following the massive Wana Decrypt0r ransomware outbreak from yesterday afternoon, Microsoft has released an out-of-bound patch for older operating systems to protect them against Wana Decrypt0r's self-spreading mechanism.
The operating systems are Windows XP, Windows 8, and Windows Server 2003. These are old operating systems that Microsoft stopped supporting years before and did not receive a fix for the SMBv1 exploit that the Wana Decrypt0r ransomware used yesterday as a self-spreading mechanism.
That mechanism is a modified version of the ETERNALBLUE exploit, an alleged NSA hacking tool leaked last month by a group known as The Shadow Brokers.
Original MS17-010 patch didn't include XP/Win8 fixes
Microsoft had released a fix for that exploit a month before, in March, in security bulletin MS17-010. That security bulletin only included fixes for Windows Vista, Windows 7, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2012, and Windows Server 2016.
As the SMBv1 is a protocol that comes built-in with all Windows versions, the computers which did not receive MS17-010 remained vulnerable to exploitation via Wana Decrypt0r's self-spreading package.
'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,' Microsoft said in a statement. 'This decision was made based on an assessment of this situation, with the principle of protecting our customer ecosystem overall, firmly in mind.'
Researchers believe that Wana Decrypt0r — also referenced online as WCry, WannaCry, WannaCrypt, and WanaCrypt0r — infected over 141,000 computers.
While unconfirmed, many believe older Windows XP and Windows Server versions were the bulk of the infections pool, as they had no way to protect themselves.
Patch systems and disable SMBv1 where possible

Besides installing these out-of-band updates — available for download from here — Microsoft also advises companies and users to disable the SMBv1 protocol, as it's an old and outdated protocol, already superseded by newer versions, such as SMBv2 and SMBv3.
The current Wana Decrypt0r outbreak has been stopped last night after a security researcher found a kill switch. This is only temporary, as the attackers could release a new version of this threat. This is why patching the SMBv1 exploit is a better solution.
For those affected, you can discuss this ransomware and receive support in the dedicated WanaCrypt0r & Wana Decrypt0r Help & Support Topic. Bleeping Computer also published a technical analysis of the Wana Decrypt0r ransomware.

Users of old Windows systems can now download a patch to protect them from this week’s massive ransomware attack.
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.
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.
Windows 10 Wanna Cry Update
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.
Wanna Cry Patch
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.
