Summary

CrowdStrike's blog details an incident where the CrowdStrike Falcon Complete team successfully thwarted a ransomware attack over a holiday weekend by acting as an extension of the customer's security team. The team used the CrowdStrike Falcon agent to detect a suspicious file download, which led to a high-severity alert. They identified nefarious activities, such as lateral movement via WMI and the use of the "living off the land" technique, and quickly contained the threat by blocking the execution of malicious files like TinyMet and Mimikatz. By network-containing affected hosts and using real-time response tools, the team identified and remediated compromised accounts and systems, preventing further lateral movement and potential ransom attempts. Their actions highlight the importance of 24/7 cybersecurity monitoring and demonstrate the effectiveness of CrowdStrike's incident response methodology in protecting organizations against breaches.
