Emissary
Send notifications via different channels such as Slack, Telegram or Teams in your bug bounty flow.
Motivation
The idea is to hook Emissary into https://github.com/BountyStrike/Bountystrike-sh which will notify me on Telegram when new domains have been found.
Usage
$ emissary
Send data through chat channels. Made by @dubs3c.
Usage:
emissary [options] [message]
Options:
-ch, --channel Specify a custom channel you have defined emissary.ini
-in, --inline Specify channel directly in the commandline
-m, --message Message to send
-h, --header Custom header
-si, --stdin Get message from stdin
-e, --email Send via Email
-txt, --text Specify the field that contains the message. Default is 'message'
-d, --data Specify additional data in json format that should be sent
-r, --rows Max rows/lines to send, 0 for unlimited. Default 20
-v, --version Show version
Examples:
emissary --channel Telegram --message "Hello telegram"
cat domins.txt | emissary -ch Slack --stdin --header "New subdomains from Google!"
emissary -ch Discord -ch Telegram -m "Your message"
emissary -in "webhook:=https://api.telegram.org/botxxxxx/sendMessage§data:={'chat_id': 'xxxx'}" -in "webhook:=https://hooks.slack.com/services/xxxxx" -m "Hack the planet!"
Create ~/.config/emissary.ini with the following:
[Telegram]
webhook=https://api.telegram.org/botxxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx/sendMessage
textField=text
data={"chat_id": "xxxxxx"}
[Slack]
webhook=https://hooks.slack.com/services/xxxxxxxxxx/xxxxxxxxxx/xxxxxxxxxx
[Teams]
webhook=https://outlook.office.com/webhook/xxxxxxxxxxxxxxxxxxxxx
[Email]
username=
password=
recipient=
server=smtp.gmail.com
port=587
subject="New domains found!"
When using gmail, you need to activate less secure apps on your account: https://myaccount.google.com/lesssecureapps
Now you can start using emissary :)
Custom Webhooks
It's possible to add your own channels as well, adding Discord as a custom channel looks like this:
[Discord]
webhook=https://discord.com/api/webhooks/xxxxxxxxxxxxxxxxxxxxxxxxxx
textField=content
And can be executed with emissary --channel Discord -m "It works!!!".
The following fields can be used for a given channel:
| field | description |
|---|---|
| webhook | The actual webhook to send data to |
| textField | Some API's have a specific json key where the message goes, here you can define that. Default key is text, e.g. {"text": "Your message"}. |
| data | If you want to send additional data, you can specify that here as a json formatted string, e.g. data={"someKey": "someValue", "otherKey": "otherValue"}. |
Pipe data via stdin:
$ cat domains.txt | emissary -ch telegram --stdin
Specify a message as an argument:
$ emissary -ch telegram --message "This is a very cool message"
Send to multiple channels:
$ cat domains.txt | emissary -ch telegram -ch slack -si
Send only 10 lines:
$ cat domains.txt | emissary -ch telegram -si --rows 10
Send everything from the file:
$ cat domains.txt | emissary -ch telegram -si -r 0
Emissary will only send 20 rows by default, this is to protect against accidentally sending a gazillion domains :) It can be overwritten with --rows 0 which means unlimited rows.
Multiple inline webhooks
It's possible use multiple webhooks directly on the command line without specifying them in config.ini.
The following command will send Hack the planet to Telegram and Slack:
emissary -in "webhook:=https://api.telegram.org/botxxxxx/sendMessage§data:={'chat_id': 'xxxx'}" -in "webhook:=https://hooks.slack.com/services/xxxxx" -m "Hack the planet!"
The same fields in config.ini are used inline as well. They can be used like so:
webhook:=<url>textField:=<key>data:=<additional json>
The character § is used as a delimiter between each field.
