CrowdStrike: ‘Significant Number’ of Affected Devices Back Online

Cybersecurity firm CrowdStrike said a “significant number” of devices that were affected by a global IT outage on Friday are now back online.

The company, whose flawed security update caused Microsoft Windows computers to crash around the world, added in a social media post that it is “still focused on restoring all systems.”

Businesses, banks, hospitals and airlines were among the hardest hit, with some still struggling to fully restore their systems.

“We understand the profound impact this has had on everyone. We know our customers, partners, and their IT teams are working tirelessly, and we are deeply grateful for that,” CrowdStrike said.

“We apologize for the disruption caused.”

The company also announced that it is rolling out a new patch that is intended to speed up data recovery from computer systems.

CrowdStrike did not say how many devices were still affected.

More than 1,400 flights to and from the U.S. were canceled on Sunday, according to air traffic tracking and data collection platform FlightAware.

The hardest hit were US airlines – Delta and United Airlines.

Health services in the UK, Israel and Germany were also disrupted on Friday, with some services cancelled.

The massive outage shed light on the vulnerability of global computer networks, showing that a single fault can cause global chaos.

“Too often these days, a single glitch can bring down an entire system, affecting sectors like healthcare, airlines, banks and car dealers,” Federal Trade Commission Chairwoman Lina Khan said in a post on social media.

“These incidents show how concentration can create fragile systems.”

Until this incident, the company was one of the most trusted brands in the cybersecurity industry.

According to its website, CrowdStrike has 29,000 customers worldwide, including major companies in the U.S.

China is also not as dependent on Microsoft as the rest of the world.
