Proposed fix for https://github.com/Neo23x0/sigma/issues/889
...
This change removes dns events from the network connection category. The
one change is that sysmon_regsvr32_network_activity.yml needs to test
the network connection category separately from the DNS event id.

Fix a couple of typos
For sysmon_hack_dumpert:
Make sure the logsource is category file_event and not sysmon. Don't set
the category at the global level. Instead set in the individual document.

Fixes for rules in new sysmon registry_event category
...
To be consistent with the behaviour of the other rules, the eventID should not
be specified as part of the rule. The category defines the eventID.
