description: This analytic looks for the presence of suspicious commandline parameters
|
||||
typically present when using Impacket tools. Impacket is a collection of python
|
||||
classes meant to be used with Microsoft network protocols. There are multiple scripts
|
||||
that leverage impacket libraries like `wmiexec.py`, `smbexec.py`, `dcomexec.py`
|
||||
and `atexec.py` used to execute commands on remote endpoints. By default, these
|
||||
scripts leverage administrative shares and hardcoded parameters that can be used
|
||||
as a signature to detect its use. Red Teams and adversaries alike may leverage Impackets
|
||||
tools for lateral movement and remote code execution.
|
||||
search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time)
|
||||
as lastTime from datamodel=Endpoint.Processes where (Processes.process = "*/c* \\\\127.0.0.1\\*"
|
||||
OR Processes.process= "*/c* 2>&1") by Processes.dest Processes.user Processes.parent_process_name

||||
| `drop_dm_object_name(Processes)` | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)`
|
||||
| `impacket_lateral_movement_commandline_parameters_filter`'
|
||||
how_to_implement: To successfully implement this search, you need to be ingesting
|
||||
logs with the process name, parent process, and command-line executions from your
|
||||
endpoints.
|
||||
known_false_positives: Although uncommon, Administrators may leverage Impackets tools
|
||||
to start a process on remote systems for system administration or automation use
|
||||
cases.
