"Honey! This stray dog has a USB drive attached to its collar, maybe its information about the owner, plug it into your PC and see."
The evilness just makes me shudder. Next up a USB stick that has a rat treat in it, when you push the stick into a USB port that pops the rat treat out of the top. You train a bunch of rats and then leave the USB sticks around your target's facility.
There are some fun fiction ideas in there, that is for sure.
I can imagine the morning news channels shouting out, "Experts say, don't let stray animals into your house, they may contain viruses. Several home owners say they've been infected with the lucrative HazCheeseburger virus."
I don't. I put the password in the SSID, as a form of a captcha. Any marginally intelligent human would break it, but an automated system sniffing out unprotected wifi won't.
I've always wondered if leaving your WiFi open gives you plausible deniability WRT to torrenting copyrighted material (should anyone ever come knocking).
AFAIK it's always been one of the bigger gray areas regarding pirating copyrighted material. From what I've read it's still a "we have no formal proof that people are prosecuted based on it, but we also have no proof that they aren't/can't be".
It is from 2008 though, things have changed. Just today a domain was seized by the UK govt on grounds of copyright infringement just because it was running a proxy. In Austria someone was convicted for running a Tor exit node about a month ago.
I doubt it makes a difference. Just having some server logs and an IP isn't really sufficient proof in the first place. Just because web requests come from my IP doesn't mean that I made those requests (it could be a friend, relative, hacker).
Computer forensics would be required to link the requests to a specific computer and person. Your ISP is probably still free to just ban you though.
They have, but it only concerns the USA, completely ignoring the rest of the world while still calling on everyone to open their networks. Understandable as they're an American organization, but annoying as a non-American. Almost as annoying as the NSA considering anyone with a non-American IP address a potential terrorist.
I am interested in building a device like this (for other purposes and not for cats), but I have no idea how to put the hardware together or where to start. I have been thingking about bycicle security a lot lately and a tiny GPS + X (gsm, wifi, etc.) might me useful.
Could someone point me in the right direction? Where do I start?
OT: Actually a useful device for cats would be a collar that tracks GPS location and answers its location when pinged. Then they can be easier found and won't get lost.
I think there are issues. Radios need quite a lot of power, while batteries must be very light and compact to not bother the cat (otherwise a collar would be eventually removed - a cat will surely find a way to do so)
I'm really surprised the cat in the article didn't tear off the collar on the first occasion.
Outdoor cats generally don't really get lost, they get flattened by cars or eaten by coyotes depending upon where you live, neither of which a GPS is going to help with. On rare occasions they get snatched up by animal control.
For anyone with a cat, I highly recommend getting it microchipped (in case they get out and happen to fall into that last category) and making it indoor-only. The average lifespan of an outdoor cat is ~3-6 years.
About a year ago our cats went from free-range to contained. We now have a contained outdoor area for them which I’ve dubbed the “cat terrarium” as it is outside my office window so I get to watch them prowl while I’m working. Photos and design explanation here: http://www.michevan.id.au/content/cat-terrarium/
A year later it has worked pretty well. I had to put some more netting along the bottom of the fence when the neighbour moved a garden bed on their side of the fence which opened up a gap they could get through. But apart from that, their escapes have always been via a door left open too long, not via the terrarium.
I really need to set up some more toys and stuff for them out there sometime. Any ideas?
I'm pleased to hear this advice, we got a cat a year ago and she has been indoor-only since we got her. We do let her out on a harness with us alongside to sniff around outdoors, and she loves it (and is sad to return inside). I feel somewhat vindicated in making her indoor-only.
That's awesome that you bring her out on a harness. I wish my cat would let me do that, but she won't; she's pretty anxious in general (adopted her when she was 2 and she had been in the shelter twice already) and still has a lot of issues (she's very loving/lovable, but very afraid of strangers, especially males).
Her anxiousness stops her from wanting to run off though, which is really, really rare for a cat, so I hang out with her on the deck in front of my place a lot so she can be "outside" but in a safe way and she doesn't leave the deck area (prior to her I wouldn't have believed this of any cat, because I grew up with some cats and all of them would attempt to run out if given the chance).
IMO indoor cats can have a perfectly fulfilled life if their owners put in some effort (regularly engage them in play that uses their built-in-hunting instincts, mine loves to chase laser pointers and play with a bird feather on a string thing, the one I use is called "Da Bird", but I'm sure other brands exist).
Just use unencrypted wifi but do anything that matters over a good VPN. Assume you can't trust your ISP and local network anyway. All this moaning about wifi security doesn't make sense to me.
It might be worth naming and shaming the ISP, so others can avoid it, if you are sure that it was definitely them and not some form of local malware infection, especially if you have some sort of evidence recorded from the incident (or can collect some by repeating it).
I'm from Mexico so it might not be as useful but my ISP is Cablevision. The only proof I've got is that it was an iframe inserted into non related pages from their server and for a specific offer they were making.
I really doubt it was any form of local malware.
1. it's a WiFi client, in other words, mostly receiver.
2. even if it were an AP, transmitting at max power for hours, it would give out very limited power (zero, give or take measurement errors).
3. you're starting from assumption "wifi baaaad" without anything to support that claim; if it were a nuclear device, I'd see a cause for concern. [citation-sorely-needed] for this assumption.
You know wifi operates in the microwave band, right? Microwave ovens operate in the 2.4 GHz band. Wifi is limited to 1 W total power output, but it's not nothing.
Edit: More to the point, it's a good question, even if the answer is "no."
Indeed: 1 W is the legal _maximum_ as per FCC rules, part 15. Not even all APs are broadcasting at this power level, this is a WiFi client (meaning that it's only transmitting a few milliseconds out of a second), and this is several orders of magnitude below the power levels used by microwaves. In other words, it is "nothing" for the purpose of cooking your cat's brain.
This would be "guilt by association: microwave ovens will cook your brains if inserted, therefore anything else using microwaves will, too, no matter what the power."
Edit: I see that you didn't mean the question rhetorically - so yes, while this may be a valid concern in the design phase, the total exposure is infinitesimal, even in prolonged use.
He's not talking about wifi's association to microwaves, he's talking about microwaves' association to microwave ovens, and the implication that anything else using microwaves will have a similar effect.
The electrons flowing through a AA battery are literally the same thing you get out of a 240V appliance outlet, but nobody worries about zapping themselves to death just because the battery makes an electric current.
There is nothing special about the use of 2.4 GHz for ovens. It is just where the regulations arbitrarily put that particular ISM band. Microwave ovens can work on 900 MHz as well.
"Zero, give or take measurement errors." As related to the GP's assumption "seems a bit harsh to the cat" - in other words, "why are you microwaving your cat, you monster!!111!", not as related to data transfer.
Oh, okay, that makes sense; I have misread it as a rhetorical question, then.
The answer is "no, your cat won't get its brains cooked, not even after prolonged exposure" - there's not even enough juice in the battery to do that :)
Thanks for the comments. I am not familiar with WiFi protocol, so I didn't know about amount of time/power antenna spends receiving/transmitting, and how the sniffing works (ie it seems to be entirely passive operation?). My karma has gone to hell ;P
There's really no reason to be concerned about that.
I'd be significantly more worried(ie: actually worried) about a mishap with that gumstick cell, which looks like it could be(edit: probably is) a lipo.
This is a bit of a stretch. Chemtrails are a baseless assumption. EM radiation has a measurable effect matter. Why not make valid points instead of insulting people?
Non-ionizing radiation has biological effects. Magnetic fields have biological effects. This is not controversial! Many replicated experiments prove it!
I am not going to say Wifi causes cancer because I don't know (doubt it). But this reflexive bleating about non-ionizing radiation needs to stop. Radio waves do not have to break DNA to affect biological tissues. They can alter many important chemical reactions.
Something having biological effects proves absolutely nothing.

So?
Also, if you are worried that spending a lot of time "exposed" to a light breeze is going to give you skin disease, you might want to read about hypochondria because you have it.
How big is the battery, and how long does it last? That'll put a firm upper bound (and, I imagine, a quite small one) on how much energy the cat could be absorbing from this.
the difference is in the wavelength. cell signals are designed to cut through water, so that you can use them when it rains. wifi signals are designed purposely to be absorbed by water (thus limiting their range to reduce interference). your brain is full of water
