WHAT HAPPENED?
CrowdStrike (CRWD.O), opens new tab, a U.S. cybersecurity company with a market value of about $83 billion, is among the most popular in the world, counting more than 20,000 subscribers around the world, the company's website shows.
The Reuters Daily Briefing newsletter provides all the news you need to start your day. According to an alert sent by CrowdStrike to its clients at 0530 GMT on Friday and reviewed by Reuters, its widely used "Falcon Sensor" software is causing Microsoft Windows to crash and display a blue screen, known informally as the “Blue Screen of Death”.
George Kurtz, CrowdStrike's CEO, said in a post on X that CrowdStrike had deployed a fix for the issue. "This is not a security incident or cyberattack," he wrote.
However, it is not clear how easily the affected systems can be fixed remotely, as the "Blue Screen of Death" is causing computers to crash on reboot before they can be updated.
"This means in this state, devices can't be updated automatically, meaning manual intervention is required," said Daniel Card, of UK-based cybersecurity consultancy PwnDefend.
Ciaran Martin, former head of the National Cyber Security Centre (NCSC), part of Britain’s GCHQ intelligence agency, said the scale of the problem was huge.
"This is not unprecedented, but I’m struggling to think of an outage at quite this scale. It has happened over the years, but this is one of the biggest. I think it’ll likely be short-lived because, the nature of the problem is actually quite simple".
