i was looking at a Simtec Electronics USB thumb drive device called the Entropy Key, which is a device to generate random bytes at a very high rate, and I was thinking how easy in concept it would be to make one. Maybe an arduino, couple of zener diodes and you got something working. The trouble I've run into is I want to run this off of the +5V from the USB port and the zener diodes don't cascade that well at such a low voltage. It would be better to be at +14V and I might be able to swing it working at +12V which there is probably more parts for. Does anyone know of a boost converter IC that will take a 5V up to these voltages?

the next time you see a problem, record as much info as you can, even if it's just saving from the browser its html source code in a text editor. Look at dns requests/responses, troute, even a ping might tell you a little bit. All else fails, look at a tcpdump of the interface.

This is not really related to to original bug, but for those using Arch Linux, theres a package called "tcplay", which will allow you to use your truecrypt volumes in a linux environment.

you should inspect the plastic case of the adapter with a magnify lens to see if it's been opened before.

im not sure if this is inside the US, but if it is i'd also like to put out there that using an rf jammer is probably highly illegal. a big company could get sued if that got caught doing that, or fined by the FCC. I doubt they would risk losing money to jam cell phones.

it also depends on how your doing you math, if you can avoid floats in ruby you can do things like this: ruby -e 'x=999999999999999; y=9999999999999999; b = x*x; puts b; puts b/x; c = y*y; puts c; puts c/y' 999999999999998000000000000001 999999999999999 99999999999999980000000000000001 9999999999999999

if what you were doing was integer based, python should be able to do it without any additional libraries: python -c 'print (110000101010000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 * 10)'; it seems also that the upper limit for floats in python is ~1.79e+308 which might be enough for what your trying to do (at least it is on my system).

one other thing that came to mind, (although this project has been canceled, probably for legality reasons) http://hackaday.com/2015/08/07/def-con-the-proxy-for-proxyham/

One thing to keep in mind, even if the packets are encrypted, if they can see the packets arriving/leaving the device as well as your connection, the timing of the packets and time in between each packet, my be enough to id and track you.

This drive http://www.amazon.com/Blue-250-Desktop-Hard-Drive/dp/B00115TE0Kwhich wasn't made in the 80's uses magnetic storage. A drive like this is susceptible to magnetic hysteresis. Granted it is older, but not totally out of use yet. You can still buy magnetic hard drives in most computer stores today.

With older magnetic storage devices data can reside on the media for longer times then just zeroing the drive (https://en.wikipedia.org/wiki/Magnetic_hysteresis) but with most types of solid state storage you can just zero it and me done with it. i.e. your typical USB flash drive can probably just be zeroed.

who here owns the address bibi81.com and similar hostnames?

you might consider looking at a linux distro DVL (en.wikipedia.org/wiki/Damn_Vulnerable_Linux). it intentionally is designed to be hacked and has some demos on things like bof, etc. It is quite old so im sure there are newer defenses that this won't cover (ASLR, NX, ROP) but it might be a good start if thats what your looking for.

Have you looked into WebGL? This might be a way to display some of those types, but I'm sure that it would take a lot of coding to to get it to do what you want it to. It is a neat thought thou

My first thought's about this was, as you increase the voltage, the chance that you will get arcing in between the two leads will also increase. Dry air has a break down voltage of about 30kV/cm. If you boost the voltage too much the wires may short out and nothing will make it to the end target. idk if those wires are insulated or not, or how well the insulation can hold up under such high voltage. The wires probably hav ea maximum rating.

I have a question, how does a mitm like this effect a tool like p0f? (i.e. if someone at the server or gateway/router was looking at traffic, would a windows computer look linuxy)

edit: bad example

just a quick question, why masscan and not nmap? I'm pretty sure nmap should be able to most types of scans, i think anyway. And will most likely be maintained well for some time to come.

Ok it was bugging me that I couldn't figure this out, but here is a jacked up way to do it: $ echo -ne "GET /file.txt HTTP/1.1\r\nHost: www.somfile.com\r\n\r\n" | nc www.somfile.com 80 | sed ':a;N;$!ba;s/\r\n\r\n/\x00/' | sed ':a;N;$!ba;s/[^\x00]*\x00//' > ./file.txt this "should" remove the headers, however as I've read, sed does not always allow the use of ; so on some systems this might not work

I know someone had already mentioned netcat but $ echo -ne "GET /file.txt HTTP/1.1\r\nHost: www.somfile.com\r\n\r\n" | nc www.somfile.com 80 > ./file.txt EDIT: this will also include the server header information, which will need to be removed. I just forgot about that.

Anyone know of a good way to keep someone from stalking them?

you could also hijack the dns requests with the pineapple http://winhelp2002.mvps.org/ has a list for the hosts file for major ad contributers edit: sorry I didnt see that was already said

Has anyone used this software? Anyone know if it's any good? hxxps://addons.mozilla.org/en-US/firefox/addon/trackmenot/

When designing the frame, you might want to try to design it so you can wear your own glasses inside of it. That way it is more "portable" for other people.

lol I downloaded py2exe just 1 week ago for the first time. Haven't had any time to play with it but looked neat.
