Researchers find bug in Wi-Fi network encryption


October 19, 2017
by Phoebe Rouge
Technologist, Office of Technology Research and Investigation

If you have a smartphone, laptop, or IoT device connected to a Wi-Fi network, the information you send over that network could be at risk. Researchers recently found a bug that lets attackers break the encryption that protects most wireless networks – leaving data you send exposed.

The bad news is that this is not a problem with a specific device, or even manufacturer – it’s a problem with the WPA2 encryption standard nearly all Wi-Fi devices on the market today use to scramble communications, preventing eavesdropping and tampering. Basically, if you use a device to connect to a wireless network at home, work, or elsewhere, this bug means you cannot rely on that connection being secure.

The good news is that the bug can be fixed with a security update or patch. Device manufacturers and software companies are aware of the bug and updates for affected devices should be rolling out in the near future, if they haven’t already.

In the meantime, connections other than Wi-Fi (like your smartphone’s 4G/3G carrier connection, or a connection with an Ethernet cable) are not affected. So, consider using them instead of Wi-Fi until the updates are available.

Even so, this bug is a reminder that there’s no single solution to secure your data, and all of the other tips for protecting your sensitive information and security online are more important than ever, including:

    Keep up with the latest updates for your software and devices, including updates for your smartphone, computer, and any IoT devices around your home.
    Avoid sending sensitive information over public Wi-Fi, whether or not it’s encrypted.
    When you do send sensitive information to a website, make sure the address starts with “HTTPS” – this will at least ensure the data you send to that one website is encrypted.
    A VPN (Virtual Private Network) app or service can give you another layer of protection for your personal data. VPNs encrypt traffic between your computer and the internet – even on unsecured networks. You can get a personal VPN account from a VPN service provider. If you decide to use one, be aware some VPNs are more secure and easier to use than others, so shop around. Read reviews from several sources, including impartial experts.

Huh? / Re: Any theories on Havana Mystery Sound that causes damage?
« on: October 17, 2017, 0056 UTC »
The Russkiis used microwaves to perturb our embassy folks, such that their eyes would bleed. Anyway, maybe the Cubans are using multiple sound beams aimed at our base, where they meet and mix inside the hearer's head? They might also be using rf and doing the same things.

Josh I remember when the Ruskies did their microwave thing towards our embassy in Moscow.  Maybe the Cubans are modulating microwaves with a (as an example) 10khz tone and the human skull could be demodulating the audio tone?  Both the microwaves and the demodulated tone would be an effective weapon on the brain.  But I suspect not... I would hope the tech folks tracking down the problem would have made microwaves RF as one of the first tests for emissions... but who knows... maybe they don't have memories as long as we do :-)

 I just had an idea...  perhaps it is UV light...  even modulated UV light... good grief !!! I'll be thinking about this all night... <heh>

Strange fast radio bursts that could be 'signals from aliens' are firing off every second in the universe

    Experts had never seen anything like fast radio bursts (FRBs) before 2001
    Some speculate they may be signals sent from intelligent life in the universe
    Harvard experts extrapolated data from one repeating FRB called 121102
    If this is representative of all FRBs then they may be firing every moment

Scientists searching for fast radio bursts that some believe may be signals sent from aliens may be happening every second.

What was once thought to be a rare phenomenon might be occurring each and every moment of the day, experts say.

Fast radio bursts, or FRBs, are radio emissions that appear temporarily and randomly, making them not only hard to find, but also hard to study.

The mystery stems from the fact it is not known what could produce such a short and sharp burst.

If the mysterious phenomena is indeed a sign of intelligent life in the universe, the latest findings could suggest it is far more widespread than previously thought.

FAST RADIO BURSTS

Fast radio bursts, or FRBs, are radio emissions that appear temporarily and randomly, making them not only hard to find, but also hard to study.

The mystery stems from the fact it is not known what could produce such a short and sharp burst.

This has led some to speculate they could be anything from stars colliding to artificially created messages.

The first FRB was spotted, or rather 'heard' by radio telescopes, back in 2007.

But it was so temporary and seemingly random that it took years for astronomers to agree it wasn't a glitch in one of the telescope's instruments.

Researchers from the Harvard-Smithsonian Center for Astrophysics (CFA) have estimated how many Fast Radio Bursts (FRBs) should occur over the entire observable universe.

Their work indicates that at least one FRB is going off somewhere every second.

When fast radio bursts (FRBs), were first detected in 2001, astronomers had never seen anything like them before.

Since then, they have found a couple of dozen FRBs, but they still don't know what causes these rapid and powerful bursts of radio emission.

Anastasia Fialkov of the CFA, who led the study, said: 'If we are right about such a high rate of FRBs happening at any given time, you can imagine the sky is filled with flashes like paparazzi taking photos of a celebrity.

'Instead of the light we can see with our eyes, these flashes come in radio waves.

'In the time it takes you to drink a cup of coffee, hundreds of FRBs may have gone off somewhere in the Universe,' added study co-author Avi Loeb.

'If we can study even a fraction of those well enough, we should be able to unravel their origin.'

To make their estimate, the scientists assumed that FRB 121102, a fast radio burst located in a galaxy about three billion light years away, is representative of all FRBs.

WHY STUDY FRBS?

The Harvard team point out that FRBs can be used to study the structure and evolution of the Universe whether or not their origin is fully understood.

A large population of faraway FRBs could act as probes of material across gigantic distances.

This intervening material blurs the signal from the cosmic microwave background (CMB), the left over radiation from the Big Bang.

A careful study of this intervening material should give an improved understanding of basic cosmic constituents, such as the relative amounts of ordinary matter, dark matter and dark energy, which affect how rapidly the universe is expanding.

FRBs can also be used to trace what broke down the 'fog' of hydrogen atoms that pervaded the early universe into free electrons and protons, when temperatures cooled down after the Big Bang.

Because this FRB has produced repeated bursts since its discovery in 2002, astronomers have been able to study it in much more detail than other FRBs.

Using that information, they projected how many FRBs would exist across the entire sky.

While their exact nature is still unknown, most scientists think FRBs originate in galaxies billions of light years away.

One leading idea is that FRBs are the byproducts of young, rapidly spinning neutron stars with extraordinarily strong magnetic fields.

FRBs can also be used to trace what broke down the 'fog' of hydrogen atoms that pervaded the early universe into free electrons and protons, when temperatures cooled down after the Big Bang.

It is generally thought that ultraviolet (UV) light from the first stars traveled outwards to ionize the hydrogen gas, clearing the fog and allowing this UV light to escape.

Studying very distant FRBs will allow scientists to study where, when and how this process of 'reionization' occurred.

'FRBs are like incredibly powerful flashlights that we think can penetrate thise fog and be seen over vast distances,' added Dr Fialkov.

'This could allow us to study the 'dawn' of the universe in a new way.'

 The full findings of the study were published in The Astrophysical Journal Letters.

Abstract

Beneficial effects of noise on higher cognition have recently attracted attention. Hypothesizing an involvement of the mesolimbic dopamine system and its functional interactions with cortical areas, the current study aimed to demonstrate a facilitation of dopamine-dependent attentional and mnemonic functions by externally applying white noise in five behavioral experiments including a total sample of 167 healthy human subjects. During working memory, acoustic white noise impaired accuracy when presented during the maintenance period (Experiments 1–3). In a reward based long-term memory task, white noise accelerated perceptual judgments for scene images during encoding but left subsequent recognition memory unaffected (Experiment 4). In a modified Posner task (Experiment 5), the benefit due to white noise in attentional orienting correlated weakly with reward dependence, a personality trait that has been associated with the dopaminergic system. These results suggest that white noise has no general effect on cognitive functions. Instead, they indicate differential effects on perception and cognition depending on a variety of factors such as task demands and timing of white noise presentation.

Propagation / Re: Propagation on the DGPS/NDB Band (200-400 kHz)
« on: September 01, 2017, 1425 UTC »
Some time ago I read this US Navy paper on VLF/LF/MF propagation, but it was more focused on VLF: http://www.navy-radio.com/manuals/0101-1xx/0101_113-02.pdf

Chris,  as you know the Navy manuals are directed more for VLF because of the Navy nuke subs, with one of the transmitting sites at Cutler, Maine.  I made a simple converter for VLF some years ago and the Cutler station was incredibly loud at my QTH 100 or so mile N/W of them :-)

I was always told that these lower frequencies need an 'excellent' ground... note I didn't say 'good' :-)

Utility / Re: Arecibo 5125 CW 1559 UTC 24 Jul 2017
« on: August 01, 2017, 2221 UTC »
Folks,
I think I received Arecibo on the night of July 31 2017 on 5125 KHZ sending a carrier for 4 minutes on and 4 minutes off, cycling that way for the hour (more really) that I listened. 0612 utc to 0736 utc.

I am quite sure it was Arecibo because it was the strongest signal on the air at this QTH.  Moderate fading from time to time but never ever got close to the noise floor.  :-)

So does this sound right ?  I didn't record it because... well... it was just a carrier...

I stopped believing in these so called 'trials' quite some time ago and here is my reasoning;

The biggest reason is these folks that do these trials start with the end finding before they even start.  In other words fatty food or whatever will kill you, now I need to show you why. They don't prove a damned thing they play with the data to make it SEEM like it is so.  

This is an issue with every type of 'science' that is done, to me it is creating false information to enrich whatever or whom ever has given (replace 'given' with bribe) the largest amount of money and a piece of paper with the outcome of the 'trial' written in large letters so the blind assholes aka 'scientist' will get it right the first time.

Also, a number of these, so called 'expert scientist' that get your tax dollars are copyrighting all data, computer models, computer code etc  So they can hide exactly how they came to their conclusion.  This makes it totally impossible for other scientist to test the data, test the computer models and computer code for accuracy.  This is unlike what happens in normal industry.  When you do testing for industry the data, computer model and computer code becomes the property and copyright ownership of the company you work for, in other words it isn't yours period.

Why does this work differently for 'scientist' that get grants from your Government?    

To be a 'scientist' today means you are bought and paid for by someone generally whom ever forks over the most cash.  It is a most sorry state for science.  It leaves persons like myself with a sh*tty taste in my mouth, that taste is a whole lot like soy this or that.  Yes I will not eat anything that has soy in it.

Science today has little or NO credibility.

Take NASA as an example;  NASA is always hyping up the possibility of life on Mars or the Moon or Doctor Who's butt etc etc so folks might tell their Representatives to give NASA more money to check this possibility out.  Well the folks at NASA know, all too well, that it is very unlikely to find life anytime in the near future.  If they do find life it most likely will be a microbe that if it came in contact with we humans if would be worse than the Black Plague.  Welcome to the 21st century folks!

The above example is a bit off topic but it reeks of the truth.

Also here's another reason why most 'science'; and 'scientists' have lost credibility in my mind.  I keep getting pop-up ads with Dr. Stephen Hawking trying to sell me some 'brain pills'... Now I admit I am not the sharpest tool in the box but Hawking hawking brain pills?  Does he think I'm an idiot?  Any jackass knows there is no such thing and he endorses them like he has used them all of his life... To that I say %&&^&#^%^&$*  and leave me alone!

Is it any wonder that I hide my sheepskin under a pile of dirty laundry?

nuff said... next...
