@DogsB said in In other news today...:
The AMD Secure Processor (AMD-SP, formerly known as PSP) is susceptible to voltage fault injection attacks.
Voltage Fault Injection attack (n.):
Voltage fault injection is a powerful active side channel attack that modifies the execution-flow of a device by creating disturbances on the power supply line. The attack typically aims at skipping security checks or generating side-channels that gradually leak sensitive data, including the firmware code.
So, only works if you have access to the hardware. As in, of no consequence to me and my PC. (Unless I decide I want to crack the encryption on YouTube's video streams.)

Yeah, I love the commation that researchers like to create when they discover shit like this. They really need to learn that if the exploit requires a philips head screwdriver at some point it's probably not that urgent. Very exciting for trying to homebrew a PS5 though.

I'm still completely amazed that this works at all. That sounds about as likely to succeed as setting the chip next to a chunk of Uranium and hoping that a bit flip skips the security check.

Is the feature's purpose just to prevent you from controlling your own hardware? Then it's just some DRM scheme and nobody on the user side has to be afraid of exploits.

A very tightly timed uranium exposure, repeated in a loop until success, but sure.
Looping a million times for an attack is normal. Remember e.g. Rowhammer, the "bang some bits until their neighbors change" attack.

Yes. It only affects content middlemen like YouTube. So we know it'll be patched post-haste in an emergency patch. So don't be surprised when the next Windows update slows your machine down by a lot.

I wouldn't, and this is completely unrelated to anything previously mentioned.

An investigation is under way to understand what happened and may result in action against the officers involved, the borough council said.
Hell no. You don't fire someone who did a dumb believing they were testing the system. You fire the idiot who put them in prod and supervisor who did nothing to stop it.
-
@homoBalkanus In the ideal world, you would. But we live in the real world. In the real world, bureaucrats are not fired, for anything basically.

@homoBalkanus Really they should fire whoever made the whack proposal. We only want dope and sick proposals, what were they thinking?

Go to any big city. I'm sure you can get dope and COVID (or other diseases) from the hooker you're propositioning.

TLDR; Traditional Tokamaks use low-temp superconductors to produce their magnetic fields, this requires huge infrastructure support. This MIT-design uses high-temp superconductors which allow for a much smaller reactor design.
The article doesn't cover it, but I presume this doesn't solve any of the myriad other issues that tokamaks still have, so still 25 years away.

Are dopesick proposals allowed? Might not matter, unless the council actually does have heroin on hand.

Interesting... "source of X" usually means that the X is being transferred in space (in outwards direction), and transfer of "elecromagentism" is usually called "radiation", so... did they invent physical oxymoron, or is the title ?

I just quickly skimmed the link, so this is a bit of a guess. This seems to be about creating a source of EM fields that stay local to the source (instead of radiating away to infinity and beyond). The idea is that you somehow have the fields cancel out further away, resulting in this:
They used another antenna to measure emissions from the device after it was turned on. They found the device able to support total suppression of far-field radiation.
I'm assuming the latter is due to the self-interference with the generated fields and not due to the EM radiation being absorbed a medium. Energy still has to go somewhere, so I'm guessing it's being returned to the source...

@topspin I thought I had seen something similar a few years ago. Not through a keyhole, but based off secondary reflections on e.g. a door. Can't find an article just now, though.

@cvi Wasn't that for sound? Recording sound in a room using a laser beam reflecting off a window is in somewhat regular use.

No - the specific example that I'm thinking of is with an open door, and bouncing laser light of it into the room and looking for the stuff that comes back. This was with very short laser pulses (many of them); I think that it was related to this somehow. (Not the best video, but again failing to find something better.)

Hadn't heard about that one, but can imagine that it might be possible. Will have to do some searching to find out a bit more.

That won't work through a keyhole. The characteristic wavelength of Wifi is 12cm or 6cm (2.4GHz or 5GHz respectively) so the keyhole is too small to let enough coherent information through (it looks like a point source or receiver and so jumbles all the backscattered information up too much). By contrast, light (or infrared) has much shorter wavelengths so you can image through smaller holes.
-
@dkf Wifi does not need a keyhole because most walls are sufficiently transparent for it.
-
@Bulb said in In other news today...:

I live in a building with nearly zero penetration of wifi through walls, as they're all heavy brick and stone. Yes, even the internal dividing walls.

Despite what the onebox suggests, that really does link to last nights winners.

At least the cladding on the outer walls doesn't resemble a hybrid/solid rocket booster.
Question is whether or not you get to enjoy the glorious modern technology of double-glazed windows.

From hist posts, he works in on some advanced science stuff.
Mad scientists in UK are required, by law, to use a castle as their base of operations.
law also allows alpine fortress, but I suppose that is quite hard to pull off in UK (also, Brexit).

Yes. They've made the house quite a lot warmer, and they're installed in such a way as to retain the stained glass. (This isn't exactly the cheapest district of the city.) That wasn't cheap…

Not a castle. No crenellations.

Oh fuck. Cathedral. Someone stuffing hamsters in a castle is one thing, but cathedral-based mad science is a more eschatological concern.
If the primary computer console isn't where the altar or organ used to be, we might be okay, maybe.

Not hamster-stuffing. Never that. A pull-along stoat is more on-message.

To cut down on weird algae growth, coloration, funny smells and other assorted phenomena downstream.

Pretty much all administrative actions like this have a built-in appeals process, so getting it reversed would typically involve no more than a writ of sent within seven to fourteen days of receipt. General rules applicable in such a case would include articles 7a (the principle of ruling for the party, if in doubt), 8 (the principle of proceeding in a manner that build trust in the public institutions), and 11 (the principle of convincing, and laying out the premises of the decision) of the Administrative Procedure Code (KPA).
I'd rate the likelihood of it ever requiring judicial review as exactly 0. The decisions would likely never become legally binding at all.
Now, sure, this requires more effort than not having to do it in the first place, but that's a bit obvious, innit?

: You can skip that part for now. We never listen to the appeals anyway. We'll add it later if there's a need.
: But it's legally required process step, isn't it?
: If I say it's not needed, then it's not needed! And I'm not paying you to write it either!
-
@acrow This is administrative, not a company. A good administrator never passes up the opportunity to show activity—they are paid either way and they definitely don't want anybody concluding they are superfluous.
-
@Bulb Showing activity and reversing a decision based on an appeal are two entirely unrelated things. You can show a great deal of activity, reviewing all the appeals veeeerrry slowly. And then ignore them all anyway.
