An update by cybersecurity firm CrowdStrike led to a major IT outage on Friday, impacting businesses around the world.
“CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts. Mac and Linux hosts are not impacted,” CEO George Kurtz said in a statement on X.
“This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed.”
He added that customers should refer to the support portal for the latest updates and work with their CrowdStrike representatives through official channels.
“Our team is fully mobilized to ensure the security and stability of CrowdStrike customers,” he added.
The comments came after widespread reports of technical issues, with Microsoft users globally being hit with an error screen known as the “blue screen of death.”
Separately, Microsoft cloud services were restored after an outage, the company said on Friday, even as many users continued to report issues.
Shares of both companies were losing ground in premarket trading on Friday morning.
