On Friday, cybersecurity company CrowdStrike pushed out a flawed software update that bricked thousands of Microsoft Windows computers around the world and halted many services. Air travel, credit card payments, emergency services, stock markets and more were affected by the Microsoft outage linked to the disastrous CrowdStrike software update.

According to Newsbyte, it reminded some of the 2010 McAfee blunder when the antivirus firm inadvertently shut down Windows XP PCs around the world.

People were even more surprised to learn that CrowdStrike’s billionaire founder and CEO George Kurtz served as McAfee’s CTO in 2010.

A post on X discussing Kurtz’s involvement in two major tech bungles has gone viral with over 1.6 million views.

Meanwhile, Kurtz’s personal net worth fell by more than $300 million on Friday due to the botched update. According to Forbes, he was worth $3.2 billion on Thursday, but his net worth fell to $2.9 billion on Friday as CrowdStrike stock fell 11 percent.

Friday’s global IT shutdown was linked to a single update that was automatically rolled out to CrowdStrike Falcon, a common cybersecurity tool used primarily by large organizations. This caused Microsoft Windows computers to crash around the world.

In a statement, Kurtz apologized for the outage and said the issue had been identified and resolved. “The outage was caused by a flaw in the Falcon content update for Windows hosts. Mac and Linux hosts are not affected. This was not a cyber attack,” he clarified.
