Before getting into the details of the release, I just wanted to impress upon you how seriously we take product security. We dedicated a significant portion of this release to improving controls around product licensing. We are fully committed to improving the security of the product and will continue to make product security enhancements a priority in future releases.
CrowdStrike also recommends upgrading to the most recent version of PowerShell and disabling previous versions, as PowerShell is backward compatible. While these additional security measures do not provide full visibility into Cobalt Strike activity, they can aid in its detection.
