Widespread IT Outage Due to CrowdStrike Update | CISA

A recent CrowdStrike update caused a widespread IT outage affecting Microsoft Windows 10 and later systems, while Mac and Linux hosts remained unaffected. The issue stemmed from the CrowdStrike Falcon content update and was not due to malicious cyber activity. CrowdStrike has identified and deployed a fix for the problem. However, threat actors are exploiting the situation for phishing and other malicious activities. Organizations are urged by CISA to heighten their cybersecurity measures, remain vigilant, and ensure employees follow guidance from legitimate sources only. CISA and international cybersecurity centers continue to monitor and support remediation efforts.
