Re-encrypting WiFi

Unfortunately, I had to shut down my open wireless network experiment. That is because I found three people within the span of two days who were both (a) criminal and (b) very stupid.

One thing to remember: if you are going to use open wireless networks to download illegal things, make sure you aren’t sharing your entire hard drive in read/write mode. Not only will the person running the network get wise to you without even needing to sniff packets, they will be able to remotely eliminate your ill-gotten files before banning you from the network. If they were so inclined, they could do much worse things to you.

I suppose I could set up a captive portal system using something like ZoneCD - thus providing scope for well behaved neighbours and passers by to use the network. That would, however, require acquiring and setting up a computer between my DSL modem and WAP. Since the two are presently integrated, the expense and bother would be even greater.

As is so always the case, a few bad apples have made it necessary to discontinue a good thing.

    Not surprised. Open networks, like any public space, must be regulated in some fashion to detect and prevent abuse. If you don’t do it on your end then someone upstream will be watching traffic registered under your identity and come to you for an explanation.

    .. my collection of low res MPEG cock-fighting videos!!

    Where have they gone?!

  4. Milan Says:

    You joke, surely.

    You would never leave such videos in a place where some random buffoon could elimate them.

    Please. The “Random Buffoon that I Live With

    (I need those videos back. For reasons that are neither illegal, nor require me to send thousands of dollars in recompense to the Puerto Rican mob.)

    On the basis of a minimal Google-based investigation, it seems that a ‘brilliante award’ is a kind of internet mind virus.

    The videos can probably still be recovered from your hard drive, provided they haven’t been overwritten. I don’t know of a way to do a multi-pass-type secure wipe on a shared drive, so all I could do was remove the flags indicating those blocks of data were important to keep.

    See: Data remanence, Data recovery, Zeroisation.

    Someone who really wanted to eliminate the files would probably have copied a hard drive wiping virus onto your system, then set it up to execute automatically when you rebooted.

    You could call your network something like: “Call XYZ number for access.” That would let you screen potential users, to some degree.

    [...] Everyone would have faster and more reliable internet access if we could shut down all but a couple of the access points. Unfortunately, there is no way to coordinate such an action. Furthermore, anyone who actually ran one of the reduced number of access points, if such an agreement could be reached, would be faced with the same kind of illicit usage that forced me to shut down my open network.
