  1. Though web app pen-testing is not my strong point I do know you can use burp suite. The professional version has some really good automating tools to use to show the flaws within you site. The professional version will set you back about 300 USD. They also have a free version, but it does not exactly have everything you are looking for. Here is a link to Burp.
  2. Have you looked at any Femto Cells? most of the time you need a contract with the provider if you have a 3rd party Femto Cell so it is not really that feasible for the general public (as well as other items that are needed... Thank you FCC ) You could also look at these 'booster/repeaters'. I have not tested these particular units myself but maybe someone else on these forums has. You could also look at making a PA-LNA-Multiplexer (maybe called a PA-LNA-Duplexer. It is early and I have not gone to bed) ; which is the same thing you will find in the link. Another question I would have is if this is just for voice, just data or both? That will depend on my answer. A side note about T-Mobile's UMA. If your friend has a Android device and T-Mobile he will not have true UMA support for his device. Now when I say true UMA support for his device I mean that when he is making a call through WiFi and then leaves the coverage area of the WiFi unit his call will be dropped and not transferred to a BTS. Though it is unfortunate it is a reality that Android users who are with T-Mobile have to live with (I also do not know of any other US cellular provider who offers true UMA/GAN support for Android devices). <rant> On another way off side note but kinda relevant to my last point. Things that Android needs to be the best cellular device period (I already like Android a lot, just a few more add-ons would make it epic) Voice over LTE (more provider side) Native SCTP support (The Linux kernel can support it, but still not in Android) True UMA/GAN support (which can utilize SCTP (again provider side) </rant> Edit: Now I know my grammar and spelling suck, but I found one mistake that was just too bad to let go.
  3. Hello All. I am new to these forums but have been looking at the post for a little while. I have notice that there is not a whole lot of talk about cellular devices or the network in which they communicate on. Cellular technology is what some would call my area of focus. I just wanted to start a thread where people can ask questions about the cellular network or devices and everyone can come together and answer the questions others my have. Remember, I do not clam to have all the answers or even most of them, I come here like most of you to learn and share with other so we may all learn from each others. I hope this thread gets utilized and help answer peoples questions. tl;dr I am new. Here is a thread for questions about cellular anything. I do not have all the answers. Hope this thread gets utilized. I hope this gets more people excited about cellular networks and devices.
  4. The VoIP Hacking Exposed book does have some good references in it, but I find parts of it out of date; well the copy I have is anyway. I find the BT VoIP wiki to be a better resource. This particular resource is still a little out of date, but will give you a good head start; and make sure to take a good look at the VLAN hopping section. I have been working on some demos with VoIP and security testing a network which has it, and been up all night setting up my VM to give an talk at a local security group this Monday. Now it has been a little over 2 years since I have really done anything with VoIP (since I became a sophomore in university) and am amazed at how far VoIP security testing has came. I will write a how to when I can (been falling behind in school because of work), but that link should give you a head start in the right direction. Hope that helps and good luck on your report.
  5. Even though I have not read the whole document and just skimmed it, I did find the bottom of page 9 kinda funny. In particular 10G. Now I know this is not saying they have some way to break any form of encryption, but it did make me think of that possibility. I found it amusing. Great document BTW.
