CNBC takes a look.<\/p>\n<\/div>\n<h2 class=\"ArticleBody-subtitle\">What is CrowdStrike and what does it do?<\/h2>\n<div class=\"group\">\n<p>CrowdStrike is a cybersecurity vendor that develops software to help companies detect and block hacks. It is used by many of the world&#8217;s Fortune 500 companies, including major global banks, healthcare and energy companies.<\/p>\n<\/div>\n<div role=\"region\" aria-labelledby=\"Placeholder-ArticleBody-Video-108008872\">\n<div role=\"button\" id=\"Placeholder-ArticleBody-Video-108008872\" class=\"PlaceHolder-wrapper\" data-vilynx-id=\"7000346214\" data-test=\"VideoPlaceHolder\">\n<div class=\"InlineVideo-videoEmbed\" id=\"InlineVideo-0\" data-test=\"InlineVideo\">\n<div class=\"InlineVideo-wrapper\">\n<div class=\"InlineVideo-inlineThumbnailContainer\"><img decoding=\"async\" class=\"InlineVideo-videoThumbnail\" src=\"https:\/\/wp.worldtechguide.net\/wp-content\/uploads\/2024\/07\/how-a-software-update-caused-one-of-the-worlds-biggest-it-blackouts.jpg\" alt=\"Major technical outages worldwide: Here's what to know\"><span class=\"InlineVideo-videoButton\"><\/span><span><\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"group\">\n<p>CrowdStrike is what&#8217;s known as an &#8220;endpoint security&#8221; firm as it uses cloud technology to apply cyber protections to devices that are connected to the internet.<\/p>\n<p>This differs from alternative approaches used by other cyber firms, which involve applying protection directly to backend server systems.<\/p>\n<\/div>\n<h2 class=\"ArticleBody-subtitle\">What happened on Friday?<\/h2>\n<div class=\"group\">\n<p>On Friday, people around the world began encountering an error screen known as the &#8220;blue screen of death.&#8221;<\/p>\n<p>This issue \u2014 a common problem among PCs, for example if a machine overheats \u2014 was the result of an update from cybersecurity firm&nbsp;<span class=\"waslinkname\">CrowdStrike<\/span>&nbsp;concerning its Falcon product.&nbsp;<\/p>\n<p>Falcon is a platform developed by the company that&#8217;s designed to stop cyber breaches using cloud technology \u2014 it is at the heart of the firm&#8217;s focus on endpoints. CrowdStrike said Friday it is in the process of rolling back the update globally.<\/p>\n<\/div>\n<div class=\"group\">\n<p>CrowdStrike&#8217;s software requires deep access to a computer&#8217;s operating system to scan for threats. In the case of Friday&#8217;s outage, machines running Microsoft&#8217;s Windows operating system crashed due to a fault in the way a software update issued by CrowdStrike interacted with Windows.<\/p>\n<p>&#8220;We have been made aware of an issue impacting Virtual Machines running Windows Client and Windows Server, running the CrowdStrike Falcon agent, which may encounter a bug check (BSOD [blue screen of death]) and get stuck in a restarting state. We approximate impact started around 19:00 UTC on the 18th of July,&#8221; Microsoft said in an update at 5:40 a.m. ET.<\/p>\n<p>&#8220;We can confirm the affected update has been pulled by CrowdStrike. Customers that are continuing to experience issues should reach out to CrowdStrike for additional assistance,&#8221; the company added.<\/p>\n<\/div>\n<h2 class=\"ArticleBody-subtitle\">A fix has been issued<\/h2>\n<div class=\"group\">\n<p>Earlier, Microsoft said its cloud services had been <span class=\"waslinkname\">restored after an outage<\/span> that affected its Azure services and Microsoft 365 suite of apps in the central U.S. region. A company spokesperson said these are two different and non-related issues \u2014 one issue relates to Azure, the other is linked to CrowdStrike.<\/p>\n<\/div>\n<div role=\"region\" aria-labelledby=\"Placeholder-ArticleBody-Video-108008807\">\n<div role=\"button\" id=\"Placeholder-ArticleBody-Video-108008807\" class=\"PlaceHolder-wrapper\" data-vilynx-id=\"7000346210\" data-test=\"VideoPlaceHolder\">\n<div class=\"InlineVideo-videoEmbed\" id=\"InlineVideo-0\" data-test=\"InlineVideo\">\n<div class=\"InlineVideo-wrapper\">\n<div class=\"InlineVideo-inlineThumbnailContainer\"><img decoding=\"async\" class=\"InlineVideo-videoThumbnail\" src=\"https:\/\/wp.worldtechguide.net\/wp-content\/uploads\/2024\/07\/how-a-software-update-caused-one-of-the-worlds-biggest-it-blackouts-1.jpg\" alt=\"Major global cyber outage hits airlines, banks and media outlets, impacting millions\"><span class=\"InlineVideo-videoButton\"><\/span><span><\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"group\">\n<p>They added that they &#8220;anticipate a resolution is forthcoming,&#8221; in respect to the CrowdStrike problem.<\/p>\n<p>CrowdStrike is &#8220;actively working with customers impacted by a defect found in a single content update for Windows hosts,&#8221; CEO George Kurtz said Friday in a update on social media platform X. He added that Mac and Linux hosts are not affected.<\/p>\n<p>&#8220;This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed,&#8221;&nbsp;<span class=\"waslinkname\">Kurtz said<\/span>.<\/p>\n<p>That fix could be hard to implement, though. Andy Grayland, chief information and security officer at threat intelligence firm&nbsp;Silobreaker, said that in order to implement a fix, engineers would have to go into each individual data center running windows.<\/p>\n<p>They&#8217;d then have to log in, navigate to a certain CrowdStrike file, delete it, and then reboot the entire system, he said.<\/p>\n<p>&#8220;Where machines are encrypted, complex encryption keys also need to be entered manually. Unless Microsoft and CrowdStrike (if they are involved) pull something miraculous out of the bag, this could be painful to recover from.&#8221;<\/p>\n<\/div>\n<div data-test=\"WildCardEmbed\">\n<div class=\"WildcardEmbed-wrapper\"> div { box-sizing: border-box; } .noselect { -webkit-touch-callout: none; \/* iOS Safari *\/ -webkit-user-select: none; \/* Safari *\/ -khtml-user-select: none; \/* Konqueror HTML *\/ -moz-user-select: none; \/* Old versions of Firefox *\/ -ms-user-select: none; \/* Internet Explorer\/Edge *\/ user-select: none; \/* Non-prefixed version, currently supported by Chrome, Edge, Opera and Firefox *\/ } .DO-widget-wrapper { width: 100%; max-width: 620px; background-color: #fff; } .DO-logo-row { margin-bottom: 10px; } .DO-body { border-top: 2px #289dcf solid; border-bottom: 2px #289dcf solid; padding: 12px 0 12px 0; margin-bottom: 20px; } .DO-bodycopy .DO-button { font-family: Proxima Nova,Helvetica,Arial,sans-serif; } .DO-bodycopy {color: #424858; font-size: 18px; line-height: 31px; margin-bottom: 12px;} .DO-button { color: #fff; font-size: 16px; font-weight: 600; width: 120px; height: 30px; background-color: #0071bc; border-radius: 6px; text-transform: uppercase; padding: 4px; text-align: center; cursor: pointer; margin-bottom: 4px; text-decoration: none !important; } .DO-button:hover { background-color: #0a94e0; text-decoration: none !important; } @media  <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>George Kurtz, co-founder and CEO of CrowdStrike Inc., speaks during the Montgomery Summit in Santa Monica, California.
