NGAV

When using NGAV on an endpoint machine, as a non-admin user on the machine, if you clicked the prompt from Windows Security Center to update the Cybereason signatures database, command window continued to display on the machine (while the update ran in the background), disrupting the work of the endpoint machine user.

We have resolved this issue to ensure that the signature database update does not interfere with normal machine usage.

Behavioral Execution Prevention

When using Behavioral Execution Prevention, the cmstp_abnormal_execution and msexchange_owapool_webshell rules were causing the Cybereason platform to generate MalOps that were false positive MalOps.

We have resolved this issue and these rules should no longer generate MalOps that are false positive.
