# Slack Webhooks Github Crawler

This script search for Slack Webhooks token publicly exposed on Github.com

Slack webhooks are easy to search on Github since they have all the same format:

`https://hooks.slack.com/services/TXXXXXXXX/BXXXXXXXX/xxxxxxxxxxxxxxxxxxxxxxxx`

## The Social Experiment

I've run this script on a cloud function every hour for 6 months and in total I've collected more than **6500 Slack Webhooks**.  

Afterward I've sent a message to all the #general channels warning that they have an exposed token on Github.  

The message received by the people was the following:  



### Results

In total I've sent ~6500 Slack messages and the youtube video that was explaining the experiment had ~3700 views, so we can assume that **roughly 57% of webhooks was still valid.**  

\* *Supposing that only one person had watched this video per channel*

## Technical Info

The script instruments a chromium instance using [puppeteer](https://developers.google.com/web/tools/puppeteer/) and use it to search github the prefix of the slack token.  

Since the big number of results the script filter for a specific programming language and for a specific sorting option every time it run.
