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:

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.
