description: 'This search looks for the execution of `adfind.exe` with command-line
|
|
arguments that it uses by default. Specifically the filter or search functions.
|
|
It also considers the arguments necessary like objectcategory, see readme for more
|
|
details: https://www.joeware.net/freetools/tools/adfind/usage.htm. This has been
|
|
seen used before by Wizard Spider, FIN6 and actors whom also launched SUNBURST.
|
|
AdFind.exe is usually used a recon tool to enumare a domain controller.'
|
|
search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time)
|
|
as lastTime from datamodel=Endpoint.Processes where (Processes.process="* -f *"
|
|
OR Processes.process="* -b *") AND (Processes.process=*objectcategory* OR Processes.process="*
|
|
-gcb *" OR Processes.process="* -sc *") by Processes.dest Processes.user Processes.process_name
|
|
Processes.process Processes.parent_process Processes.process_id Processes.parent_process_id
|
|
| `drop_dm_object_name(Processes)` | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`
|
|
| `windows_adfind_exe_filter`'
|
|
how_to_implement: To successfully implement this search, you need to be ingesting
|
|
logs with the process name, and command-line executions from your endpoints. If
|
|
you are using Sysmon, you must have at least version 6.0.4 of the Sysmon TA.
|
|
known_false_positives: administrators rarely use adfind, usually not used for legitimate
