definition: Note that you have to configure logging for Named Pipe Events in Sysmon
|
|
config (Event ID 17 and Event ID 18). The basic configuration is in popular sysmon
|
|
configuration (https://github.com/SwiftOnSecurity/sysmon-config), but it is worth
|
|
verifying. You can also use other repo, e.g. https://github.com/Neo23x0/sysmon-config,
|
|
https://github.com/olafhartong/sysmon-modular. How to test detection? You can
|
