custom organization-specific macos packages that use .pkg files to run curl could trigger this rule. if known behavior is causing false positives, it can be excluded from the rule.	t1059 t1071 macos elastic

if you are seeing more results than desired, you may consider reducing the value for threshold in the search. you should also periodically re-run the support search to re-build the ml model on the latest data.	t1071 t1071.004 endpoint splunk
in modern windows systems, unable to see legitimate usage of this process, however, if an organization has legitimate purpose for this there can be false positives.	t1071 t1071.001 windows sigma
it is likely that the outbound server message block (smb) traffic is legitimate, if the company's internal networks are not well-defined in the assets and identity framework. categorize the internal cidr blocks as `internal` in the lookup file to avoid creating notable events for traffic destined to those cidr blocks. any other network connection that is going out to the internet should be investigated and blocked. best practices suggest preventing external communications of all smb versions and related protocols at the network boundary.	t1071 T1071.002 endpoint splunk
it is possible legitimate traffic can trigger this rule. please investigate as appropriate. the threshold for generating an event can also be customized to better suit your environment.	t1071 t1071.004 endpoint splunk

web activity that occurs rarely in small quantities can trigger this alert. possible examples are browsing technical support or vendor urls that are used very sparsely. a user who visits a new and unique web destination may trigger this alert when the activity is sparse. web applications that generate urls unique to a transaction may trigger this when they are used sparsely. web domains can be excluded in cases such as these.	t1071 ml elastic
