Threat Intelligence Slack Bot

Motivation

As organizations mature and scale their security infrastructure, it's vital that analysts, engineers, and other team members are able to query and enrich data on demand. Additionally, application features are being introduced at an increasing rate, creating the need for software defined infrastructure. In this project, we'll be exploring scaling automation efforts - with a focus on Threat Intelligence. This project can serve as a guide for when to leverage an interactive bot, creating API endpoints, serverless architecture, and applying actionable threat intelligence.

Architecture Overview

Threat Intel Slack Bot is completely serverless, and is built and deployed using Serverless.js.

There are three Lambdas controlling the process:

• slashmessage: Function to serve as API Gateway and facilitate execution of cloud functions to query Threat Intelligence databases
• passivetotal: Triggers indicator query (Domain Names only) to Passive Total and return response to Slack Channel
• virustotal: Triggers indicator query to VirusTotal and return response to Slack Channel

One Command Deploy

serverless deploy

Environment Variables

When deploying Threat Intel Slack Bot, serverless.yml defines the environment variables that will be passed to lambda functions.

VIRUSTOTAL_API_KEY

PASSIVETOTAL_USERNAME

PASSIVETOTAL_APIKEY

export SLACK_API_TOKEN=<SLACK API KEY>
export VIRUSTOTAL_API_KEY=<VIRUSTOTAL API KEY>
export PASSIVETOTAL_USERNAME=<PASSIVETOTAL API USERNAME>
export PASSIVETOTAL_APIKEY=<PASSIVE TOTAL API KEY>
