Seriously? A backdoor that uses Telegram as C&C server?

BrainDamage is a fully featured python based backdoor that uses Telegram as C&C server.

It is a hypothetical evolution of backdoor (very unlikely, from my point of view), so it’s a good idea to analyze its source code and its behavior.

#whoisonline- list active slaves This command will list all the active slaves.
#destroy- delete&clean up This command will remove the stub from host and will remove registry entries.
#cmd- execute command on CMD Run shell commands on host
#download- url (startup, desktop, default) This will download files in the host computer.
#execute- shutdown, restart, logoff, lock Execute the following commands
#screenshot- take screenshot Take screenshot of the host of computer.
#send- passwords, drivetree, driveslist, keystrokes, openwindows This command will sends passwords (saved browser passwords, FTP, Putty..), directory tree of host (upto level 2), logged keystrokes and windows which are currently open
#set- email (0:Default,1:URL,2:Update), filename (0: Itself, 1: Others), keystrokes (text) This command can set email template (default, download from url, update current template with text you’ll send), rename filenames or insert keystrokes in host.
#start- website (URL), keylogger, recaudio (time), webserver (Port), spread This command can open website, start keylogger, record audio, start webserver, USB Spreading

#wallpaper- change wallpaper (URL) Changes wallpaper of host computer
#find- openports (host, threads, ports), router This command will find open ports and the router the host is using

The setup is pretty simple:

First, install some requirements:

Then, starts the installation

Telegram setup: - Install Telegram app and search for “BOTFATHER”. - Type /help to see all possible commands. - Click on or type /newbot to create a new bot. - Name your bot. - You should see a new API token generated for it.
Dedicated Gmail account. Remember to check “allow connection from less secure apps” in gmail settings.
Set access_token in eclipse.py to token given by the botfather.
Set CHAT_ID in eclipse.py. Send a message from the app and use the telegram api to get this chat id.

bot.getMe() will give output {‘first_name’: ‘Your Bot’, ‘username’: ‘YourBot’, ‘id’: 123456789}
