CrowdStrike, the cyber security and technology company, has blamed a bug in an update for the recent push of bad data to customers, which jumpstarted the global tech outage that affected air travelers, caused bank disruptions, and a plethora of technological issues across the country.

Rolling Updates

The company has stated measures that they’ll take to keep the issue from recurring that range from the way they rollout updates, to providing customers with the option to update, as well as more information about their internal plans.

Undetected Errors

On Wednesday, Crowdstrike released its “preliminary post incident review” which explained that the issue was partially caused by an “undetected error” in the content-configuration update for the Falcon platform affecting Windows machines.

Problematic Content Data

The content-validation system allowed “problematic content data” to affect CrowdStrike users, which started an “unexpected exception” which caused Windows operating systems to go down.

New preventative measures will include heftier internal testing and “a new check” that should keep “this type of problematic content” from being released in the future.

Up and Running

According to CrowdStrike, a “significant number” of the nearly 8.5 million machines affected on Friday are now back up and running. Customers are still waiting on a more detailed description of the causation. CrowdStrike has said that they will release a more detailed version of events once their investigation is complete. While customers wait for the company’s explanation, CrowdStrike has garnered a significant amount of attention online for sending out $10 Uber Eats gift cards as an apology for the incident.

A spokesperson for CrowdStrike stated the company sent gift cards “to our teammates and partners who have been helping folks through this situation.” Customers and clients were exempt from this gratitude. The spokesperson said that Uber later flagged the cards as fraud “because of high usage rates,” without giving more details on how many cards were sent out and when.
