'In the short term, they're going to have to do a lot of groveling'

The great irony of the CrowdStrike fiasco is that a cybersecurity company caused the exact sort of massive global outage it was supposed to prevent. And it all started with an effort to make life more difficult for criminals and their malware, with an update to its endpoint detection and response tool Falcon.

It was simply incorrect, and worse: CrowdStrike's validation system to check that content updates will work as expected did not flag up the broken channel file that was about to be pushed out to everyone. The validator software was buggy, allowing the bad update to slip out when the release should have been stopped.it shouldn't touch.

By the time CrowdStrike pushed a fix to correct the error, millions of Windows machines weren't able to escape the boot loop."So the fix really only helped the systems that had not turned into the blue screen of death yet," Renfrow told. For systems that were already screwed, the broken channel file needed to be deleted or replaced, typically by hand which is bad news for anyone with thousands of PCs to repair.

As the recovery process continues, Renfrow said he expects to see CrowdStrike start sending support personnel to its customers' locations. Some of the people who received the discount codes said that when they tried to redeem them, they received a message saying the code had been cancelled and would not be honored.
