As organizations work to remediate affected systems, it's crucial to stay alert to phishing campaigns and spoofed domains set up by threat actors attempting to exploit the outage.
CrowdStrike's Remediation Measures
CrowdStrike has provided a solution utilizing the Falcon sensor’s built-in quarantine functionality to remove the problematic channel file causing Windows systems to crash. According to CrowdStrike, when a Windows system with Falcon installed contacts the CrowdStrike Cloud, a request is issued to quarantine the faulty file, visible in the Falcon UI. If the file does not exist, no quarantine occurs, and systems operate normally. The solution may require two or three reboots to take effect due to a timing issue between the file's quarantine and activation. For best results, CrowdStrike recommends using a wired network connection to minimize latency.
