SlackEnum: A user enumeration tool for Slack

SlackEnum

A user enumeration tool for Slack.

Setup

Clone this repository and install the necessary dependencies with the commands below.

git clone https://github.com/Wh1t3Rh1n0/SlackEnum

cd SlackEnum

python3 -m pip install -r requirements.txt

Create the cookies_dir and http_requests_dir folders defined in the settings at the top of slackenum.py.

By default, these are slack_ids-cookiebro and slack_ids-burp and can be created by running the commands below.

mkdir slack_ids-cookiebro

mkdir slack_ids-burp

Use

python3 slackenum.py <TARGET/TARGETS LIST> [–sanity]

• <TARGET/TARGETS LIST> – May be either a single email address or a file containing one email address per line.
• --sanity – Option to “sanity check” all Slack identities before launching a long running user enumeration job.

Instructions

1. Create one or more Slack user accounts from which to execute user enumeration. (Referred to as “Slack identities” or “Slack IDs”.) Multiple accounts (100 or more) are recommended to perform user enumeration at higher/useable speeds.
2. Log into each user account you’ve created and join the users to the same Slack workspace.
3. While logged into Slack, use the CookieBro browser extension to export your cookies in JSON format. Save the exported cookies to a file in the slack_ids-cookiebro folder.
4. Repeat steps 2 and 3 for every additional user account you want to use with SlackEnum.
5. Edit the settings at the top of slackenum.py. At a minimum, you must change the default_host setting to the Slack subdomain of your workspace.

Example:

# The hostname of the workspace where all your Slack IDs reside.
default_host = 'YOUR-WORKSPACE.slack.com'

6. Optionally sanity check your Slack IDs before launching a real enumeration campaign by targeting a known-valid Slack account and including the --sanity flag.

Example:

7. When everything is ready, start enumerating users.

• the number of Slack IDs you have loaded,
• the number of users you are targeting,
• your timing options,
• and some estimations of how long enumeration could take, based on all of those factors.

If you press Enter to continue, enumeration will begin and the output will look similar to the output below.

Output is also logged to the output_file and error_log defined in the settings at the top of slackenum.py. By default, these are slack-users.csv and errors.txt.
