Weaponizing the Nokia N900 – Part 3.7 – More goodness and packet injection!

Thanks to Shawn Merdinger, from infosecisland for the inspiration and  thanks to many others in the information security community, I’m continuing with my ‘Weaponizing the Nokia N900’ series with another entry.

Firstly, I would like to mention that I’m contemplating on writing a program to automate the process of turning your N900 into a pentester’s device. This is largely due to the fact that the neopwn project seems to have come to a stand still. I have attempted contacting an individual from the neopwn project, however I haven’t had much luck.

In this post I will cover some of the other attacks you can carry out with your N900 as a rogue ap point using dns spoofing and David Kennedy‘s Social Engineering Toolkit. Along with that, I’ll give you information on how to get packet injection working so the aircrack suite is more useful to you.

Rogue AP Goodness:

1.) Download SET to your n900 and take note of this information:

a.) You’ll need to install some additional python modules  such as, python-crypto. Python-crypto is in the repositories if you have the extra repositorise that I mentioned  in an earlier post: http://zitstif.no-ip.org/?p=451

b.) I wasn’t able to find python-pexpect in the repositories, but luckily SET was able to download it and install it for me.

c.) If you’re planning on using metasploit in tandem with SET, you’ll need to do as follows:

ln -s /usr/bin/rub1.8 /usr/bin/ruby

Oddly enough, SET does not do a check for whether or not if you have ruby installed. I would implement something like this some where in the SET project:

http://zitstif.no-ip.org/setfix.txt

2.) See my earlier post on how to setup your n900 as a rogue ap point: http://zitstif.no-ip.org/?p=459 (Keep in mind though we’re going to inject a new step or two.)

3.) After step 4 (in the earlier rogue ap point instructions) load up SET and select number 2 for the website attack vectors section

4.) Select option 1 for the java applet attack method

5.) Now select the site cloner option

6.) Select a website to clone (Hmm anyone up for Facebook?! 😉 )

7.) For the payload, give SET’s own payload a try, it’s pretty powerful and you can even run a keylogger. In addition to that for the moment, this attack bypasses some AV solutions. (The system I tested this on was a fully patched Windows 7 x64 system that has Microsoft Security Essentials up to date, and I was able to get a session without any AV alarms going off.)

8.) Before you fire up ettercap, go to etter.dns and create an entry like this (especially if you’re using the mobilehotspot application)

www.facebook.com     A      10.105.242.1

9.) Now run this:

ettercap -i wlan0 -q -T -p -u // // -P dns_spoof

What I adore about this attack, is the java applet infection method. It’s a great social engineering method for gaining access to victim’s machines. Plus with SET, you don’t need sun-java6-jdk, which doesn’t appear to be available in the n900’s repositories.

I also wanted to note, that I wasn’t able to get the java applet to work against OSX systems or Linux systems. 🙁

Aircrack-ng goodness:

I was able to get packet injection working and was able to successfully use the chop-chop attack on a WEP network to create enough IVs and then crack the WEP key in about 10 minutes.

Be careful about using this driver because it seems to drain battery life quite quickly.

(Speaking of which..)

Additional notes:

One more tip I would like to share with fellow N900 owners on extending battery life is as follows:

-Uninstall applications that eat up a lot of CPU time and run in the background

-Disable your wifi connection if you’re not using it

-Dim the brightness of your screen

-Disable anything you don’t need or aren’t currently using

-Use an application to that allows you to switch between 3G and 2G networks. If you’re just using SMS and calling people, all you need is the 2G network. (In my humble opinion)

That’s all for now. As usual, more to come!

Blippy FAIL rant

mashable.com/2010/04/23/blippy-credit-card-numbers/

Alright, sharing information is nothing new, along with sharing information online. We as a society aggregate massive amounts of data for companies to use for targeted marketing and the like.

With that being said, you must ask yourself, “Our we willingly sharing too much information?” Is there such a thing as a too much information? Some would argue no and for the most part I would have to agree with them. Despite this being true, I still strongly believe that reasonable forms of denial are a useful tool for coping with everyday life.

Twitter, facebook, myspace.. and even the faded out xanga, are all websites that are used for basically spying on our social lives. With this being said, Blippy steps up the ante by spying on our buying habits and having a space for us to publicly share this information.

Was I a little surprised to find out about the latest ‘Blippy fail’ ? A little, but the more I took into consideration and remembered how Google can be used in such a way, it wasn’t very hard for me to fathom.

Is there an easy mend for this issue? You have to ask yourself, especially if you’re a Blippy user, “Do I really need to share this information, with this company and the realm of the internet?”.

My mantra on disclosing information is, ‘share information as felt necessary’. I hope more people start taking this into consideration, but it seems that people tend to like to live in the view of the public to an extent via social networking mediums. I believe for some individuals, it gives them a sense of identity and self importance.

Do I really care about who broke up with such and so? Is it necessary for me to learn about unnecessary information about yourself? I don’t think so, but social networking websites seem to think it’s necessary, but it’s also part of their business model.

Consider this simple logic: The more websites that I share personal information with, the more likely a privacy breach of information that I did not intend to disclose will occur.

More to come..
