Misusing Ethernet To Kill Computer Infrastructure Dead 303

Some attacks on computers and networks are subtle; think Stuxnet. An anonymous reader writes with a report at Net Security of researcher Grigorios Fragkos's much more direct approach to compromising a network: zap the hardware from an unattended ethernet port with a jolt of electricity. Fragkos, noticing that many networks include links to scattered and unattended ethernet ports, started wondering whether those ports could be used to disrupt the active parts of the network. Turns out they can, and not just the ports they connect to directly: with some experimentation, he came up with a easily carried network zapping device powerful enough to send a spark to other attached devices, too, but not so powerful -- at least in his testing -- to set the building on fire. As he explains: I set up a network switch, and over a 5 meters Ethernet cable I connected an old working laptop. Over a 3 meters cable I connected a network HDD and over a 100 meters cable I connected my “deathray” device. I decided to switch on the device and apply current for exactly 2 seconds. The result was scary and interesting as well. The network switch was burned instantly with a little “tsaf” noise. There was also a buzzing noise coming from the devices plugged-in to the network switch, for a less than a second. There was a tiny flash from the network HDD and the laptop stopped working. It is not the cheapest thing in the world to test this, as it took all of my old hardware I had in my attic to run these experiments. I believe the threat from such a high-voltage attack against a computer infrastructure is real and should be dealt with.

Comment Even better: Let recruiters PAY you to find a job! (Score 1) 2

The whole thing is a sales pitch for a new site called June where you get paid to listen to pitches from recruiters trying to fill positions. With the extra perk of trying to build some Uber-like accountability into the process.

But this might be a good sales pitch. Too bad they didn't pay me to read it. But I'm guardedly optimistic, might actually pay attention to them once they get the thing launched.

You shouldn't poop in Windows anyway, that's rude.

Thousands of year ago, could anyone imagine poop that would spy on you and report your actions to the king?

And most people have no idea what "anthropogenic" means either, so sticking "A" in front of AGW just makes it more vague.

Attenuated Global Warning is what you are supporting.

Can we stop saying AGW already? People who don't know what you're talking about certainly won't know what you're referring to, and I can never remember what the "A" means.

Just call it Global Warming already, don't be lazy if you think it's really important. It's more important to get the message across than use a vague acronym.
