Easy-Creds aka the mosfun you can have with a strangers facebook account.

No, I'm not advocating that you hack random people's Facebook accounts, but I thought the title was catchy. Easy-Creds is a really sweet bash script written by Eric Milam that utilizes other tools (i.e ettercap & sslstrip) to capture credentials mostly via man in the middle attacks (MITM). Normally, I would do a type up on how to set up easy-creds for MITM. However, this week I found a well done youtube video on how to set up easy-creds. I like this video for two reasons. First, it exemplifies the quality that I would like to have in my videos once I am in a position to make them. Secondly, it does a terrific job of walking the viewer through the set up process.

The only thing I would add too this is at approximately 4:24 when he is explaining how to fix your dchp3-server, his advice is great, but it won't work for everyone.

When you go to update/install dhcp3 inside easy-creds you will most likely recieve an error message similiar to this:

The following packages have unmet dependencies:
dhcp3-server: Depends: dhcp3-common (= 3.1.3-2ubuntu3.2) but 3.1.3-2ubuntu3.3 is to be installed
E: Broken packages
root@bt:~#

 An alternative solution to the one he outlines in his video is to force a install of the version of dhcp3-common that bt5 is asking us for. One method for doing this is to use synaptic package manager. What follows is a short walk through:

apt-get install synaptic

Once synaptic is done installing fire it up and search for dhcp3-common. It should appear at the top of the search results. Select dhcp3-common then click on the "Package" menu at the top of the screen. Select "Force Version.." A new menu should appear with a drop down box. Select, "3.1.3ubuntu3.2 (stable)" then click force version, and finally "Mark." Press the "Apply" button with the green check mark. When the dialog box opens up, review the changes you are about to make and verify that everything is correct. Let synaptic install the package and then close the program.
Unfortunately, you will be removing dhcp3-common, dhcp3-gtk, dhcp3-daemon, and also Wicd. In my opinion the removal of these other packages makes this a flawed solution, but one that we can fix. It is very important at this point you do not reboot or make any sudden movements towards the power button on the front of your computer. If you do, you'll find that using the internet/networking just got  a lot harder with out Wicd. Open up a terminal and reinstall wicd:

apt-get install wicd

After wicd is installed, go ahead and install dhcp3-server.

apt-get install dhcp3-server

Now, when you go to add the "at0" interface in the walk through your file should appear the same as it does in the video.
