description: The Linux make command is used to build and maintain groups of programs
|
|
and files from the source code. In Linux, it is one of the most frequently used
|
|
commands by the developers. It assists developers to install and compile many utilities
|
|
from the terminal. If sudo right is given to make utility for the user, then the
|
|
user can run system commands as root and possibly get a root shell.

|
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 into the Endpoint datamodel. If you are using Sysmon, you can use the
|
|
Add-on for Linux Sysmon from Splunkbase.
