description: The following analytic identifies a default behavior of a MetaSploit
  payload. MetaSploit uses Apache Benchmark to generate payloads. The payloads contain
  standard artifacts including "Apache Benchmark" and the original file name is always
  ab.exe. During triage, review the process and it's path. It is possible network
  connections spawned from it. Review parallel processes for further behaviors.
data_source:
- Sysmon Event ID 1
search:
  selection1:
    OriginalFileName: ab.exe
  condition: selection1
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. In addition,
  confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
  endpoint product.
known_false_positives: False positives should be limited as there is a small subset
  of binaries that contain the original file name of ab.exe. Filter as needed.
