EvilSlackbot - A Slack Bot Phishing Framework For Red Teaming Exercises

EvilSlackbot

A Slack Attack Framework for conducting Red Team and phishing exercises within Slack workspaces.

Disclaimer

This tool is intended for Security Professionals only. Do not use this tool against any Slack workspace without explicit permission to test. Use at your own risk.

Background

Thousands of organizations utilize Slack to help their employees communicate, collaborate, and interact. Many of these Slack workspaces install apps or bots that can be used to automate different tasks within Slack. These bots are individually provided permissions that dictate what tasks the bot is permitted to request via the Slack API. To authenticate to the Slack API, each bot is assigned an api token that begins with xoxb or xoxp. More often than not, these tokens are leaked somewhere. When these tokens are exfiltrated during a Red Team exercise, it can be a pain to properly utilize them. Now EvilSlackbot is here to automate and streamline that process. You can use EvilSlackbot to send spoofed Slack messages, phishing links, files, and search for secrets leaked in slack.

Phishing Simulations

In addition to red teaming, EvilSlackbot has also been developed with Slack phishing simulations in mind. To use EvilSlackbot to conduct a Slack phishing exercise, simply create a bot within Slack, give your bot the permissions required for your intended test, and provide EvilSlackbot with a list of emails of employees you would like to test with simulated phishes (Links, files, spoofed messages)

                        Outfile to store search results
  -cL, --channel_list   List all public Slack channels

Token

To use this tool, you must provide a xoxb or xoxp token.

Required:
  -t TOKEN, --token TOKEN  (Slack xoxb/xoxp token)

python3 EvilSlackbot.py -t <token>

Attacks

Depending on the permissions associated with your token, there are several attacks that EvilSlackbot can conduct. EvilSlackbot will automatically check what permissions your token has and will display them and any attack that you are able to perform with your given token.

Attacks:
  -sP, --spoof   Spoof a Slack message, customizing your name, icon, etc (Requires -e,-eL, or -cH)

  -m, --message  Send a message as the bot associated with your token (Requires -e,-eL, or -cH)

  -s, --search   Search slack for secrets with a keyword 

  -a, --attach   Send a message containing a malicious attachment (Requires -f and -e,-eL, or -cH)

Spoofed messages (-sP)

With the correct token permissions, EvilSlackbot allows you to send phishing messages while impersonating the botname and bot photo. This attack also requires either the email address (-e) of the target, a list of target emails (-eL), or the name of a Slack channel (-cH). EvilSlackbot will use these arguments to lookup the SlackID of the user associated with the provided emails or channel name. To automate your attack, use a list of emails.

python3 EvilSlackbot.py -t <xoxb token> -sP -e <email address>

python3 EvilSlackbot.py -t <xoxb token> -sP -eL <email list>

python3 EvilSlackbot.py -t <xoxb token> -sP -cH <Channel name>

Phishing Messages (-m)

With the correct token permissions, EvilSlackbot allows you to send phishing messages containing phishing links. What makes this attack different from the Spoofed attack is that this method will send the message as the bot associated with your provided token. You will not be able to choose the name or image of the bot sending your phish. This attack also requires either the email address (-e) of the target, a list of target emails (-eL), or the name of a Slack channel (-cH). EvilSlackbot will use these arguments to lookup the SlackID of the user associated with the provided emails or channel name. To automate your attack, use a list of emails.

python3 EvilSlackbot.py -t <xoxb token> -m -e <email address>

python3 EvilSlackbot.py -t <xoxb token> -m -eL <email list>

python3 EvilSlackbot.py -t <xoxb token> -m -cH <Channel name>

Secret Search (-s)

With the correct token permissions, EvilSlackbot allows you to search Slack for secrets via a keyword search. Right now, this attack requires a xoxp token, as xoxb tokens can not be given the proper permissions to keyword search within Slack. Use the -o argument to write the search results to an outfile.

python3 EvilSlackbot.py -t <xoxp token> -s -o <outfile.txt>

Attachments (-a)

With the correct token permissions, EvilSlackbot allows you to send file attachments. The attachment attack requires a path to the file (-f) you wish to send. This attack also requires either the email address (-e) of the target, a list of target emails (-eL), or the name of a Slack channel (-cH). EvilSlackbot will use these arguments to lookup the SlackID of the user associated with the provided emails or channel name. To automate your attack, use a list of emails.

python3 EvilSlackbot.py -t <xoxb token> -a -f <path to file> -e <email address>

python3 EvilSlackbot.py -t <xoxb token> -a -f <path to file> -eL <email list>

python3 EvilSlackbot.py -t <xoxb token> -a -f <path to file> -cH <Channel name>

Arguments

Arguments:
  -f FILE, --file FILE  Path to file attachment
  -e EMAIL, --email EMAIL  Email of target
  -cH CHANNEL, --channel CHANNEL  Target Slack Channel (Do not include #)
  -eL EMAIL_LIST, --email_list EMAIL_LIST  Path to list of emails separated by newline
  -c, --check   Lookup and display the permissions and available attacks associated with your provided token.
  -o OUTFILE, --outfile OUTFILE Outfile to store search results
  -cL, --channel_list   List all public Slack channels

Channel Search

With the correct permissions, EvilSlackbot can search for and list all of the public channels within the Slack workspace. This can help with planning where to send channel messages. Use -o to write the list to an outfile.

python3 EvilSlackbot.py -t <xoxb token> -cL

Evil QR - Proof-of-concept To Demonstrate Dynamic QR Swap Phishing Attacks In Practice

Toolkit demonstrating another approach of a QRLJacking attack, allowing to perform remote account takeover, through sign-in QR code phishing.

It consists of a browser extension used by the attacker to extract the sign-in QR code and a server application, which retrieves the sign-in QR codes to display them on the hosted phishing pages.

Watch the demo video:

Read more about it on my blog: https://breakdev.org/evilqr-phishing

Configuration

The parameters used by Evil QR are hardcoded into extension and server source code, so it is important to change them to use custom values, before you build and deploy the toolkit.

Here are all the places in the source code, where the values should be modified:

server/core/config.go:

build_run.bat

chmod 700 build.sh
./build.sh

TLDHunt - Domain Availability Checker

TLDHunt is a command-line tool designed to help users find available domain names for their online projects or businesses. By providing a keyword and a list of TLD (top-level domain) extensions, TLDHunt checks the availability of domain names that match the given criteria. This tool is particularly useful for those who want to quickly find a domain name that is not already taken, without having to perform a manual search on a domain registrar website.

For red teaming or phishing purposes, this tool can help you to find similar domains with different extensions from the original domain.

Dependencies

This tool is written in Bash and the only dependency required is whois. Therefore, make sure that you have installed whois on your system. In Debian, you can install whois using the following command:

sudo apt install whois -y

How It Works?

To detect whether a domain is registered or not, we search for the words "Name Server" in the output of the WHOIS command, as this is a signature of a registered domain. If you have a better signature or detection method, please feel free to submit a pull request.

Domain Extension List

You can use your custom tlds.txt list, but make sure that it is formatted like this:

.aero
.asia
.biz
.cat
.com
.coop
.info
.int
.jobs
.mobi

How to Use

➜  TLDHunt ./tldhunt.sh
 _____ _    ___  _  _          _   
|_   _| |  |   \| || |_  _ _ _| |_ 
  | | | |__| |) | __ | || | ' \  _|
  |_| |____|___/|_||_|\_,_|_||_\__|
        Domain Availability Checker

Keyword is required.
Usage: ./tldhunt.sh -k <keyword> [-e <tld> | -E <exts>] [-x]
Example: ./tldhunt.sh -k linuxsec -E tlds.txt

Example of TLDHunt usage:

./tldhunt.sh -k linuxsec -E tlds.txt

You can add -x flag to print only Not Registered domain. Example:

./tldhunt.sh -k linuxsec -E tlds.txt -x
