Beggining Hardware/electrical/robotics Hacking Tutorial

Target rocks. Save the led's, I'll cut them off in the next video. Buy a multimeter, digital...unless you understand the caveats of analog.

nmap lesson 2 (begginer)

Ok so you know how to nmap:
nmap 192.168.1.1
and you know how to nmap –P0 –O
nmap 192.168.1.1 –P0 –O
So now you want to know more. Ok so let’s find out your IP address. If you are in windows do an ipconfig if you are in *nix do a ifconfig. Ok so typically your behind a wireless router or something if you have cable or dsl. Or if your range is in between any of these:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
That means you have a private IP address and that your router navigates the internet for you using NAT(PAT technically). So you need to find your publicly routable address. To find this goto ipchicken.com and it will tell you your external IP. So let’s say your IP is 68.52.155.53. Ok take this address and run it through arin.net or ripe.net if you are in Europe or afrinic if you are in Africa, etc..
Ok so my address gives me two, possible selections for Comcast:
Comcast Cable Communications, Inc. JUMPSTART-1 (NET-68-32-0-0-1)
68.32.0.0 - 68.63.255.255
Comcast Cable Communications, Inc. NASHVILLE-3 (NET-68-52-128-0-1)
68.52.128.0 - 68.52.159.255

I am going to choose the Nashville one because that is where I am at and it is a smaller range.
So I want to narrow my range down as much as possible so I have less results to look at. So I want to scan IP’s that are near mine, because most likely those are other Comcast customers and potentially even my neighbors. So I want to scan the range 68.52.155.x . x is going to stand for 0 through 255 and I also want to output this to a text file so that I can review it later, because it is going to take a long time. So here is my command:
nmap 68.52.155.0/24 –P0 –O –oN bob.txt
This well output everything to bob.txt in the current directory.
Next Lesson, interpreting ports.

nmap step 1(begginer)

Your first nmap lesson.
Nmap is a port scanner, you can use it to find open ports. Once you find the open ports you can discover whether or not they are exploitable. Nmap can also be helpful in network troubleshooting or determining what os is behind what ip. But this tutorial just explains the basic scanning portion. You will need to download nmap. Nmap is at:
http://nmap.org/download.html
When you install it, it will come with WinPCAP which updates your TCP/IP stack. It will install this as part of the install. The version of NMAP you choose may come with a GUI, don’t use it. Use the cli.

Ok so after you get through installing nmap open the cmd. So start cmd, by hitting start, then run, then typing cmd. In vista you only need to hit start then type cmd. Now to aim nmap at your target you type:
nmap targetiporname
That will work for most targets, example:
nmap google.com
However that doesn’t work for all targets, some targets have ICMP(ping) turned off, and nmap pings a target to make sure it is up before scanning. So you may want to turn that feature off. So type:
nmap targetiporname –P0
Ok so that is a capital P and a zero. Usually I want to to know the OS my target is using as well so I do a
nmap targetiporname –P0 –O
And that is a capital O, so you should be able to scan your target now. I will right step 2 very soon, if you have any troubles with step 1 just get in contact with me.

True Crypt for n00bs.

http://www.truecrypt.org/
The truecrypt install is straight foreword and similar to the install of most other applications. The first install screen will ask whether to install or extract, and the default which is install is fine. Again on the next page most likely the defaults are fine and then click install. It will ask if you want to see the release notes, click no. Then click finish. Now to open truecrypt. Double click on the true crypt icon on your desktop.


Click create volume. Now for this tutorial we will choose to create a file container then click next and then click create a standard true crypt volume.

Choose where to save your encrypted file volume. The default of AES and RIPEMD-160 are sufficient. You will need to remember what encryption scheme you used so either make a mental note or write it down. I like to make my truecrypt file 600 megs, so if I need to archive it or send it somewhere to be archived(like a lawyer), then it will fit on a cd.

Your password is important and you must remember it, it needs to be a strong password. Strong passwords are denoted by five characteristics. They need to have Upper Case and Lower Case letters and Symbols and numbers. Length is the other factor. Ie@Tpietw1ce@d4Y, is a strong password. You can use a key file if you want but it will complicate things if you want to use your encrypted file on another computer or if that keyfile is corrupted. As far as volume format the defaults are fine. Now to mount your file as a volume go to the main truecrypt screen.


Choose a drive letter like H: . Hit the select file button. Choose your file. Hit the mount button. You will be prompted for your password. Your file will be mounted as the h: drive and anything you put in it will be encrypted. Remember to dismount the drive with the dismount all button whenever you are not using it.
