Austin, Texas.- A “significant number” of the millions of computers that crashed on Friday, causing disruptions around the world, are back up and running, cybersecurity firm CrowdStrike said Monday, as its clients and regulators await a more detailed explanation of what went wrong.
A flawed software update sent by CrowdStrike to its customers on Friday disrupted the operations of airlines, banks, hospitals and other crucial services, affecting about 8.5 million machines running Microsoft’s Windows operating system. The painstaking work of fixing it has typically required a company’s technology team to manually delete files from affected machines.
CrowdStrike said in a blog post Sunday night that it was beginning to implement a new technique to speed up the fix for the problem.
Shares of the Texas-based cybersecurity firm have fallen nearly 30% since the crisis, wiping out billions of dollars in stock market value.
The scope of the damage has also caught the attention of government regulators, including antitrust authorities, although it remains to be seen whether they will take action against the company.
“Too often today, a single failure results in a system-wide disruption, affecting industries from health care and airlines to banks and auto dealerships,” Lina Khan, chair of the U.S. Federal Trade Commission, wrote on Social Network X on Sunday. “Millions of people and businesses pay the price. These incidents reveal how concentration can create fragile systems.”
