name: Windows Rename System Utilities Wmic exe LOLBAS in Non Standard Path
|
||||
id: 42c9b37c-6928-4e54-8043-2d5265d972dd
|

version: 1
|
||||
description: The following analytic identifies Wmic.exe which is a native living off
|
||||
the land binary or script (LOLBAS) within the Windows operating system that may
|
||||
be abused by adversaries by moving it to a new directory. The list of binaries was
|
||||
derived from the https://lolbas-project.github.io site.
|
||||
search: ssa_input = | from read_ssa_enriched_events() | eval device=ucast(map_get(input_event,
|
||||
"dest_device_id"), "string", null), user=ucast(map_get(input_event, "dest_user_id"),
|
||||
"string", null), timestamp=parse_long(ucast(map_get(input_event, "_time"), "string",
|
||||
null)), process_name=lower(ucast(map_get(input_event, "process_name"), "string",
|
||||
null)), process_path=lower(ucast(map_get(input_event, "process_path"), "string",
|
||||
null)), event_id=ucast(map_get(input_event, "event_id"), "string", null)| where
|
||||
process_name IS NOT NULL AND process_name="wmic.exe"| where process_path IS NOT
|
||||
NULL AND match_regex(process_path, /(?i)\\windows\\syswow64\\wbem/)=false | eval
|
||||
start_time=timestamp,end_time=timestamp, entities=mvappend(device, user), body=create_map(["event_id",
|
||||
event_id, "process_path", process_path, "process_name", process_name]) | into write_ssa_detected_events();
|
||||
how_to_implement: To successfully implement this search, you must be ingesting logs
|
||||
with the process name, command-line arguments, and parent processes from your endpoints.
|
||||
Collect endpoint data such as Sysmon or Windows Events 4688.
|
||||
known_false_positives: False positives may be present and filtering may be required.
|
||||
Certain utilities will run from non-standard paths based on the third-party application
|
||||
in use.
