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.

Microsoft issues first Windows XP patch in 3 years to stymie 'WannaCrypt'. On a network by exploiting the vulnerabilities Microsoft patched with MS17-010; the malware can also infect other. Download security update KB4012598 for Microsoft Windows XP, Server 2003 and 8. The security update (KB4012598, MS17-010) was released on 13 May 2017 for the following Microsoft Windows versions, the dowload links go to www.microsoft.com: Download KB4012598 for Windows XP SP3 x86; Download KB4012598 for Windows XP SP3 for XPe x86. What is Microsoft's MS17-010 Windows patch? Microsoft released a critical. Never click on links you don't recognise or download files from people you don't know or trust. The Sun website is.
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. Dark elf historia r18 patch download.
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.

Earlier today, Microsoft concluded an investigation which it started yesterday after a mysterious group of hackers known as The Shadow Brokers dumped a trove of Windows exploits online, as part of a plan started last year and aimed at ousting the Equation Group cyber-espionage group as the NSA, and so, exposing the US’ foreign hacking operations.

Yesterday's data dump contained tools for hacking various Windows OS versions, and documents revealing the NSA’s alleged implication in the hacking of several banks around the world, and EastNets, one of the SWIFT departments managing and monitoring SWIFT transactions across Middle East banks.
Fallout 1 patch download. A collective of security researchers have analyzed the leaked exploits yesterday afternoon, which helped us put a list of all the exploits, here.
As promised, the Shadow Brokers dumped a series of Windows hacking tools, some of which they put up for sale in a public auction last December and January.
Because of the broad spectrum of exploits and the large number of affected Windows versions, there was speculation that most Windows computers connected to the Internet were vulnerable to easy hacking. This was a fair assumption since it took around an hour to download the Shadow Brokers dump, install it, and start targeting any Internet-facing PC.
Microsoft concludes investigation
While EastNets vehemently denied it was breached just hours after the dump, Microsoft took a more proper approach and said it was reviewing and testing the exploits.
A day later, the Redmond giant says that most of the dumped exploits had already been patched in previous years, and some of them, even this year.
Below is a list of Equation Group (NSA) exploits that Microsoft says it patched.
ETERNALBLUE
An exploit targeting the SMBv2 protocol, which Microsoft patched this year via MS17-010.
EMERALDTHREAD
Another SMB protocol exploit, one which targeted versions since XP and Server 2003 to 7 and Server 2008 R2. Microsoft says it patched this one in MS10-061.
ETERNALCHAMPION
An exploit for the SMBv1 protocol that Microsoft patched last week, in April 2017’s Patch Tuesday. Since this is the months Microsoft dumped the Security Bulletins format, you’ll need to navigate to Microsoft’s new Security Guidance portal and search for the fixes for CVE-2017-0146 and CVE-2017-0147.
ERRATICGOPHER
A SMBv1 protocol exploit that targeted only Windows XP and Server 2003. Microsoft didn’t elaborate, and only said “Addressed prior to the release of Windows Vista.”
ESKIMOROLL
Labeled as an Kerberos exploit targeting 2000, 2003, 2008 and 2008 R2 domain controllers, Microsoft said MS14-068 contains a patch for these attacks.
ETERNALROMANCE
Possibly one of the most dangerous exploits included in the Shadow Brokers dump, this is an SMBv1 flaw that can be exploited over TCP port 445, and which targets Windows XP, 2003, Vista, 7, Windows 8, 2008, 2008 R2. Successful exploitation gives an attacker remote SYSTEM privileges. If you installed MS17-010, the patch is sufficient to mitigate the risks.
EDUCATEDSCHOLAR
An SMB exploit that we know very little of, but Microsoft says it patched this back in 2009 via MS09-050.
ETERNALSYNERGY
Microsoft Ms17-010 Windows Patch Download
An SMBv3 remote code execution flaw in Windows 8 and Server 2012, which Microsoft says it patched via the same MS17-010.
ECLIPSEDWING
An RCE exploit for the Server service in Windows Server 2008 and later, but this too, was patched years before, in MS08-067.

Microsoft says that exploits such as ENGLISHMANSDENTIST (Outlook), EXPLODINGCAN (IIS 6.0), and ESTEEMAUDIT (RDP) will not receive any patches since they don’t work on supported Windows platforms.
“Customers still running prior versions of these products are encouraged to upgrade to a supported offering,” Microsoft said.
Of all patches, the most critical to apply is MS017-010, which was part of the March 2017 Patch Tuesday. Now the question remains. Did the Shadow Brokers tell Microsoft in advance of the tools they planned to dump?
Key question: When was @Microsoft notified about the @NSAGov vulns patched in March (MS17-010)? #Shadowbrokers came forward on 13 Aug 2016. https://t.co/fp46jskgWQ
— Edward Snowden (@Snowden) April 15, 2017Did Shadow Brokers release because of coordinated disclosure? Or did Microsoft burn them so they released anyway? Either way, update! https://t.co/FCkWtcqhuN
— Thomas Fox-Brewster (@iblametom) April 15, 2017There are no acknowledgements for MS17-10 which patched most of the big bugs from the ShadowBrokers drop. https://t.co/IBXIOLceqM
