Just curious if anyone knows if it would be possible to connect the BashBunny to multiple hosts simultaneously? I understand that the BashBunny probably wouldn't be able to run a normal payload (I.E. HID, Serial, etc.) to multiple systems at a time unless it was running as an Ethernet Adapter, but I was wondering if it is potentially possible as it can run a DHCP Server that can hand out multiple addresses.
I.E. If you were able to obtain access to a server room or other location where there are multiple hosts that the BashBunny could be connected to at the same time (since servers are generally stacked in a rack) and have a payload execute upon issuing an address to said hosts.
Maybe like using a USB Female to Female adapter connected to a USB Hub and using USB Male to Male cables to connect to the hosts.
Just some food for thought and possible research.
**Obviously, there would be some major research, scripting, and automation involved to create such a payload.

Hello All,
My first time here and would like to say that I though this payload really interesting, but I do have a question might me dumb but didn't find an answer anywhere.
The idea for the shell.bat script is a place holder that can be replaced by my own bat file. I know I can generate one on cmd on windows but does anyone have a sample or a template on how it should look like so I would replace with the proper info and save the bat file?
I am new into it and I am stuck on this part.
Thank you!
The shell script is meant to provide you with a shell into the "victim's" computer (research how reverse shell's work, there's tons of video's on youtube for it). You can also package an exe or any file of your choosing for your remote shell, just adjust the script(s) accordingly.

Hello all,
I am posting the Ducky Script for the USB Intruder I made available on the BashBunny. If you would like to run USB Intruder on the TwinDuck FW, you will need to download the BashBunny payloads from Github and delete the payload.txt from the USB_Intruder payload folder and replace it with the following code for the inject.bin file. I'm being lazy on this post, so if you want more information on it, check the readme.md from my BB Payload. You will also need to name the storage "Ducky" (minus the quotes) in order for this payload to execute properly.

Haha, I love this. I had a feeling so I tried. I connected to your thread with my Win test VM that is running Avast and it went off like a christmas tree, only on your thread and then ti blocked me from viewing it hehe. Another test you can try is on your test machine put Avast on it and see if your payloads still run or if they are killed.
It should only be blocking the shell.bat file as it is known by AV mfg's. It was only put on there as an example/placeholder (the LHOST is set to 10.10.10.10 and LPORT to 8443). It's just a Veil-Evasion generated payload. Everything else should execute just fine.

I will be updating my initial post with the new and updated scripts in the near future.

I can suggest some improvements that can not only keep it compatible with the twin ducky but also shorten your Quack commands.
Place all your commands into a powershell script except for the privilege escalation. Make your first quack commands get you privilege escalated cmd and then the second to pull and run the script from the USB location. That will make your quack statements only necessary for getting the cmd prompt and running the script. Cleanup of the registry can even be handled at the end of the script in the script also. Since it is using USB it will still work for the Twin Duck too.
Thanks for the suggestion. I've cut down runtime by 13 or so seconds with that. I did have to keep the creation of the ProgData folder and Hidden attribute in the first part of the cmd prompt phase to allow for a destination of the initial copy, but I'll be updating this again in the near future. I left the shell.bat launch as is since it creates a separate hidden instance for it to run in rather than having it hanging up a script of scripts right at the end (since they're run sequentially).
-
Yes, it was created/tested post BB 1.3 FW upgrade.
-
You're going to love it (the bashbunny). I'll be modifying this payload in the future (maybe not the near future...) and adding to it as well. Feel free to hit me up on IRC or PM on here - goes for everyone.

Thing is, to create an Admin user you first need Admin rights, therefore you don't really get anywhere with creating a Meterpreter payload.
It doesn't have to be a meterpreter payload, that's the beauty of it. That bat file (shell.bat) can be quite literally anything you want it to be and do what you want it to do.
--Also, I know I'm using the old form of ducky script for the HID commands, but I wanted to make it cross platform and have the ability to be used on a TwinDucky as well.

Just a first script for the BB for me guys, chill and have an alco beverage or something. No need to get worked up. It's not necessarily meant for a corp env. I appreciate the constructive criticism, but I had fun and it was just a first step.

Posting for discussion and feedback. I will be submitting this for approval into the repository in the near future. I have attached a zip containing all necessary files as well for those of you that want to pick it up and run with it.
Read the README below and in the zip first, and post any comments or questions you may have.

Thank you Dice, your find assisted in the creation of a WORKING ps1 script.
$BB = Get-WMIObject Win32_Volume | ? { $_.Label -eq 'BASHBUNNY' } | Select-Object -First 1 -ExpandProperty Driveletter $driveEject = New-Object -comObject Shell.Application $driveEject.Namespace(17).ParseName("$BB").InvokeVerb("Eject")I've tested it with multiple drive letters and it PROPERLY ejects the drive.
THANK YOU TO EVERYONE WHO CONTRIBUTED! - I only hope that this helps for future payloads.

Actually, when you're ejecting the storage, it SHOULD only stop the storage attackmode, leaving HID or any other "non-ejectable" devices (attackmodes) still running from the BB payload. I'll play with this during the day and post said results here.
-
Thanks Sebkinne, looking forward to my first upload to the github repo here in the near future.
-
Is there any way to have the BashBunny safely eject on completion of the payload (on windows)? If so, how?

I'll pop my defective one open tonight and let you know.

Didn't see the link till now, but I doubt that would work. That just makes my head hurt thinking of how to make the connection work properly even if we could supply power to it...

Yes, the LANTurtle is (basically) a micro PC (you can really make one [or at least kind of] from a Pi Zero [youtube "seytonic $7 LANTurtle"]). It would be feasible, but you have the potential to be fighting with the DHCP server of the network you're attacking. This attack could potentially work great for ARP poisoning though or remote shell access into a network.
-
Great Question,
I don't believe that would be a possibility (out of the box) as the computer that the LAN Turtle is connected to is receiving it's information from the USB side of the adapter, and the Ethernet end is only being used for traffic to the computer. However, if you get into the LAN turtle via SSH you could more than likely change the configuration for the network adapters or payloads and possibly have the turtle do what you would like (but again, it would require re-configuring the adapters or payload on the turtle).
-- I am not 100% certain of this, but this is what my logic is telling me (which sometimes is broken).
-
Has anyone installed expect (on the BB) and attempted scripting it into payloads? - Just trying to see if this is a feasible option for payloads.

Exactly, that's why I was curious. I'm just not sure how exactly it could be done, but I was just thinking about it while I was trying to sleep last night. - Curiosity, nothing more.
