The bug reportedly led to systems all over running on Windows operating system to crash and display the blue screen of death error. The firm said that their Falcon platform sensor was a security agent installed on devices such as laptops and desktops. Falcon was supposed to protect these systems from threats. 

On Saturday, Microsoft said that around 8.5 million devices had been impacted due to the outage across sectors like banking, aviation, with losses still piling up. An insurance company estimated the cumulative bill to be around $5.4 billion for Fortune 500 companies. 

CrowdStrike will likely be investigated further about the incident. Kurtz has been summoned by Congress lawmakers to testify about it.
