Image: Malwaretech.com.<\/p>\n<\/div>\n<p>On Friday, May 12, countless organizations around the world began\u00a0fending off attacks from a ransomware strain variously known as WannaCrypt, WanaDecrypt and Wanna.Cry. Ransomware\u00a0encrypts a victim\u2019s documents, images, music and other files unless the victim pays for a key to unlock them.<\/p>\n<p>It quickly\u00a0became apparent that Wanna was spreading with the help of <a href=\"https:\/\/technet.microsoft.com\/en-us\/library\/security\/ms17-010.aspx\" target=\"_blank\">a file-sharing vulnerability in Windows<\/a>. Microsoft issued a patch to fix this flaw back in March 2017, but organizations running older, unsupported versions of Windows (such as Windows XP) were unable to apply the update because Microsoft no longer supplies security patches for those versions of Windows.<\/p>\n<p>The software giant today made an exception to that policy after it became clear that many organizations hit hardest by Wanna were those still running older, unsupported versions of Windows.<\/p>\n<p>&#8220;Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful,&#8221; <a href=\"https:\/\/blogs.technet.microsoft.com\/msrc\/2017\/05\/12\/customer-guidance-for-wannacrypt-attacks\/\" target=\"_blank\">wrote<\/a> <strong>Phillip Misner<\/strong>, principal security group manager at the Microsoft Security Response Center. &#8220;Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers.&#8221;<\/p>\n<p>The update to address the file-sharing bug that Wanna is using to spread is now available for Windows XP, Windows 8, and Windows Server 2003 via the links at the bottom of <a href=\"https:\/\/blogs.technet.microsoft.com\/msrc\/2017\/05\/12\/customer-guidance-for-wannacrypt-attacks\/\" target=\"_blank\">this advisory<\/a>.<\/p>\n<p>On Friday, at least 16\u00a0hospitals in the United Kingdom were forced to divert emergency patients after computer systems there were infected with Wanna.\u00a0According to multiple stories in the <a href=\"http:\/\/www.telegraph.co.uk\/news\/2017\/05\/12\/nhs-hit-major-cyber-attack-hackers-demanding-ransom\/\" target=\"_blank\">British media<\/a>, approximately\u00a090 percent of care facilities in the U.K.\u2019s <strong>National Health Service\u00a0<\/strong>are still\u00a0using Windows XP \u2013 a 16-year-old operating system.<\/p>\n<p>According to <a href=\"https:\/\/twitter.com\/JakubKroustek\/status\/863188326039396352\" target=\"_blank\">a tweet<\/a> from\u00a0<strong>Jakub Kroustek<\/strong>, a malware researcher with security firm\u00a0<strong>Avast,\u00a0<\/strong>more than 100,000 Windows systems have been compromised by the Wana ransomware.<\/p>\n<p>For advice on how to harden your systems against ransomware, please see the tips in <a href=\"https:\/\/krebsonsecurity.com\/2016\/12\/before-you-pay-that-ransomware-demand\/\" target=\"_blank\">this post<\/a>.<\/p>\n<p><a href=\"https:\/\/krebsonsecurity.com\/2017\/05\/microsoft-issues-wanacrypt-patch-for-windows-8-xp\/\" target=\"bwo\" >https:\/\/krebsonsecurity.com\/feed\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><img decoding=\"async\" src=\"https:\/\/krebsonsecurity.com\/wp-content\/uploads\/2017\/05\/wanamap-580x256.png\"\/><\/p>\n<p><strong>Credit to Author: BrianKrebs| Date: Sat, 13 May 2017 13:00:06 +0000<\/strong><\/p>\n<p>Microsoft Corp. today took the unusual step of issuing security updates to address flaws in older, unsupported versions of Windows &#8212; including Windows XP and Windows 8.
