Endpoint security solutions play a critical role in protecting an organization’s network and connected devices. When these security solutions have vulnerabilities, either intentional or unintentional, they can open the door to some serious cyber-attacks, potentially causing major disruptions. To stay ahead of threats, security providers regularly release updates or patches that not only improve performance, but also strengthen security. Sometimes, these updates can contain flaws and lead to some unintended consequences. A recent example of this is the Crowd-Strike incident, which caused a global service outage. This paper takes a closer look at what happened during the CrowdStrike incident, the services that were impacted, and the catastrophic aftermath. The release of a flawed update from Crowdstrike Falcon software caused 8.5M Windows devices to crash. This incident led to widespread disruptions, such as Blue-Screen-of-Death(BSOD).
