How a CrowdStrike update knocked out systems globally

An update from cybersecurity giant CrowdStrike (CRWD) is causing chaos worldwide as airlines, hospital systems, businesses, and banks face massive disruptions from the outage. Yahoo Finance Tech Editor Dan Howley joins Market Domination to discuss the fallout and how affected companies are handling the outage. The outage occurred when CrowdStrike sent out an update for its software, which is used by Microsoft (MSFT) along with several Fortune 500 companies. Microsoft is the world’s largest operating system for laptops and desktops, and as a result, businesses relying on Microsoft were also affected by the outage. Howley explains, “When an update goes out, it points to different flaws in systems that attackers also learn about. An update goes out, the information is published about it. Attackers aren’t dumb, and so they know what the update’s fixing. If companies don’t apply those updates and fix those flaws, then attackers can go after them. So, the updates were applied across the board to CrowdStrike customers and that’s why we saw this huge cascade of failures.“ He adds that CrowdStrike is working on deploying a patch, but it may take longer for companies to get the fixes. In the meantime, some companies are manually fixing issues where they can in order to get operations back on track. However, Howley notes, “It’s not something that they can just automate. And so it’s not something they’re just going to go away at the drop of a hat. This is something that’s going to take a while to truly remediate.“ #youtube #news About Yahoo Finance: Yahoo Finance provides free stock ticker data, up-to-date news, portfolio management resources, comprehensive market data, advanced tools, and more information to help you manage your financial life. - Get the latest news and data at - Download the Yahoo Finance app on Apple () or Android () - Follow Yahoo Finance on social: X: Instagram: TikTok: @yahoofinance?lang=en Facebook: LinkedIn:
