how_to_implement: To successfully implement this search you need to be ingesting information
|
||||
on process that include the name of the process responsible for the changes from
|
||||
your endpoints into the `Endpoint` datamodel in the `Processes` node.
|
||||
known_false_positives: Limited false positives will be present. Typically, applications will use `BitsAdmin.exe`. Any filtering should be done based on command-line arguments (legitimate applications) or parent process.
