DolphinAtack: Inaudible Voice Commands Anonymous 09/02/2017 (Sat) 08:40:52 [Preview] No. 10987 [Reply] [Last 50 Posts]
Speech recognition (SR) systems such as Siri or Google Now have become an increasingly popular human-computer interaction method, and have turned various systems into voice controllable systems(VCS). Prior work on attacking VCS shows that the hidden voice commands that are incomprehensible to people can control the systems. Hidden voice commands, though hidden, are nonetheless audible. In this work, we design a completely inaudible attack, DolphinAttack, that modulates voice commands on ultrasonic carriers (e.g., f > 20 kHz) to achieve inaudibility. By leveraging the nonlinearity of the microphone circuits, the modulated low frequency audio commands can be successfully demodulated, recovered, and more importantly interpreted by the speech recognition systems. We validate DolphinAttack on popular speech recognition systems, including Siri, Google Now, Samsung S Voice, Huawei HiVoice, Cortana and Alexa. By injecting a sequence of inaudible voice commands, we show a few proof-of-concept attacks, which include activating Siri to initiate a FaceTime call on iPhone, activating Google Now to switch the phone to the airplane mode, and even manipulating the navigation system in an Audi automobile. We propose hardware and software defense solutions. We validate that it is feasible to detect DolphinAttack by classifying the audios using supported vector machine (SVM), and suggest to re-design voice controllable systems to be resilient to inaudible voice command attacks.

Another reason why voice-activation is not ready to be used, and is a major security hole. They already save recordings of your voice, and this just adds onto the bullshit.

I remember reading an article from some security conference about extracting data from infected computer through inaudible sound signals, perfect for some airgapped machines. This is basically the opposite, you can send commands with data streams, and since it runs proprietary voice recognition software, you may consider it a malware.

This isn't scary stuff at all. It's exactly what's expected when you try and use algorithms on the real world. Only consumerist robots fall for idiotic technology like "biometrics" and "voice control". The same will happen for self-memeing cars (well it already has happend with both Lidar and Tesla).

In essence, yes, but I think that technically TEMPEST is just about shielding and preventing the interception of natural side-channel information that results from computing, i.e. a system's normal EM emissions, sound production, etc.

If I remember what anon is referring to correctly, it was a computer that was actually infected with malware that was designed to exfiltrate information from the computer using sound, so it wasn't about purely passive interception. A successful attack of this kind would require getting your malware onto the machine first. It was a neat proof of concept, though.

Linux has been pozzed Anonymous 09/02/2017 (Sat) 17:02:41 [Preview] No. 10991 [Reply] [Last 50 Posts]

A stand-idn mascot that has appeared in the latest Linux kernel isn’t intended to push out the traditional penguin named Tux but to benefit the plight of the Tasmanian devil.

A meat-eating marsupial, the devil is bordering on extinction as the animal has been ravaged over the past decade by a transmittable cancer, one of only two known in the world. The devil is found only in the Australian island state of Tasmania.

Tuz was the mascot for January’s Linux conference in Australia, which was held in Tasmania and where the show’s annual charity auction was dedicated to raising funds to research devil facial tumor disease (DFTD).

DFTD over the past decade has wiped out up to 50% of devils, known for their offensive odor when under stress and their loud and disturbing screech.

Why have you reported on these revelations as if they are a malicious change?

Increasing diversity is not bad, it attempts to include all races of people using the service, if it was only one specific race using the software, images depicting diversity would not be needed, but the fact that all races use the internet means that they should all be represented. If all of the people in the picture were white, it would piss off everyone else. If they were all black, it would piss off everyone else. The internet is a medium where ones actions are of more importance than ones ability, if you act stupid, your going to be treated badly regardless of race.

Including people in the logo was a mistake, it should simply be the typical bitcoin logo with some decorations around it.

Not as much, and even if it did it'd piss different groups off, but I agree with your main point.
Not to mention that most people there are still white, so really /pol/ is bitching about nothing.
I think too often people see something that's not "pro-X" as somehting that's "anti-X". Which is naturally what happens with idpol.

>Pseudonymous identity is needed when you want your readers to follow your publications and posts without settling down to stylometry or some obscure sekrit klub shit because ordinary people, you know, are accustomed to trusting an authority rather than random anonymous especially when they see him in the first time.
These people are oblivious to the benefits of the anonymous imageboard, judging a post based on it's quality rather than the creator behind it. It doesn't matter if posts on here are made by bots, intelligent users, shills, etc., they are all perceived as the same and will be interpreted accordingly.

>Of course it does some job on profiling this identity to le ebil gubmints much easier, but they have more advanced ways on tracking you, like packet flow and time correlations which doesn't really make a difference whether you post anonymously, pseudonymously or with your state ID and photo as profile pic.
While they may have more advanced tools and tactics for identifying website visitors and users, it doesn't mean I should go ahead and make it a little easier for them by creating an account just because they already possess the tools to reveal my identity. Higher level tools don't make the seemingly weaker dangers of an account trivial, they all have the potential to fuck you over, and protecting your identity means eliminating as many risks as possible.

>Anon you really don't understand why web 2.0 javascript memery is in action, well it's because web servers don't have unlimited powers and bandwidth to serve every animation as css style and give out full html on every page for 500000 users every second, this is what cdns and (((le ebil cloud))) are used for combined with dynamic page content. It is easier for server to give out 1KB pointer to js library on amazon cdn and a 20KB script, then feed you with small portions of text 100KB each on demand, instead of giving you 1MB page every time you click a button, because internet overall is shit too, but sure, it works out for little imageboards like this one, and still tinyboard doesn't display post replies without javascript, ask devs and admins why.
Perhaps I didn't thoroughly explain what I meant by "enhance the appearance". Websites are moving towards animated and bloated pages with loads of "features" and drop down menus to appeal to mainstream website frequenters, and as a consequence, static web pages are being phased out. Why fix something that isn't broken? The static web page worked perfectly and can be interpreted by the majority of browsers, including extremely light text only browsers, and they don't overload your computer in the process. I shouldn't need a modern computer (Which is basically a supercompuer when compared to technology around 10-15 years ago) to view websites.

>let me guess, you are 20-35 years old, right? Then stop larping, okay, you ARE millenial.
I am not, and my age is not relevant to this discussion. It is evident that the new animated websites with unnecessary "features" are aimed towards the groups who typically only frequent a few select mainstream websites, and these groups are typically composed of individuals classified as "millenials". The internet for the average person is only around 20-30 websites, they only seen a few trees in the massive forest that is the internet.

>judging a post based on it's quality rather than the creator behind it
It is much easier for a newcomer to judge posts by creator because he can clearly see the posting history, ordinary people are accustomed to pseudonymous identities which they understand.
There must be some sort of identity if you want to gain credibility and trust also.
Users will be turned off when they see a bunch of trolling slide inane comments with corporate spam like there is on fourchan for example.

>Websites are moving towards animated and bloated pages
Well, you were the one who said this website's target audience are redditors, and reddit is not an "animated website with unnecessary "features"", it is rather old-fashioned and sometimes cryptic. All fashionable animations you see there are usually present in rare subreddits and done with pure html5 css, which simple graphic browsers (what web was actually designed for, markup and graphics) like Dillo support very well (oh, don't tell me that you have an urgent need to read entertainment web sites in links framebuffer mode because your X server is down again :^)
Web was not meant to be universally accessible, first web browser didn't have support for Apple II or IBM 5150 and was rather bloated compared to gui gopher/bbs clients. As I said, modern web clients are fast on average, mobiles even have javascript hardware acceleration, there is no need for most webdevs to fire up their neurons and write super efficient code if they can launch a site in 15 minutes with preconfigured frameworks and themes. Human nature is laziness. However, it doesn't mean there are no good static webpage sites, it means they can afford to be static because their servers/internet connection are fast and their audience is not that big.

>tfw my average internet is 20-30 imageboards and irc channels

Oh, by the way we both use le reddit spacing as they call it on 8ch, probably because text is too tiny and lack of tabulations. This board clearly needs some good modern styles, a markdown support and drop-down menus :^)

Trying to gain credibility is as bad as trolling, both are relapses to a normalfag pattern of behaviour where it has become a hindrance simply due to force of habit. Both handle the new internet environment as a novelty that is only to be crushed like windows in a bus stop until you get bored and return to your real life as a cuck for the jew.

Not the dude you're replying to, but the original web was in fact usable by someone on an Apple II or IBM 5150. All you needed was a modem and a Unix shell account from which you could run Lynx, Pine/Elm, Tin, ircII, and so forth.
Now it's no longer the case, because many pages are non-functional without javascript. Even the wayback machine (web.archive.org) has gone in that direction, which is pretty ironic.
I think the web is too far gone to save at this point, so I'm abandoning it for the most part. I no longer login to the old web forums I used to frequent, especially after they changed to become more "modern". And I don't even bother to fill out captchas, so the popular chans are written off. Anyway those things don't work in a plain vt220 console.

Mozilla To Build New Browsers That Conform To Internet Censorship


In November of 1737, decades before America officially declared its independence from the king of England, a young Benjamin Franklin published an essay in The Pennsylvania Gazette entitled, “On Freedom of Speech and the Press.” In it, Franklin wrote, “Freedom of speech is a principal pillar of a free government; when this support is taken away, the Constitution of a free society is dissolved, and tyranny is erected on its ruins.” Franklin went on to write, “An evil magistrate entrusted with power to punish for words, would be armed with a weapon the most destructive and terrible.”

Although this was written in an article published more than two and a half centuries ago, Franklin’s words are quite possibly more relevant today than they ever have been. Indeed, there is an ongoing effort by the progressive left and extremists such as George Soros to silence speech that doesn’t align with the liberal agenda. This effort to effectively gut the First Amendment is taking place virtually everywhere you look, from the mainstream media, to Hollywood, to college campuses, and perhaps most frequently, across the Internet.

Recently, the popular Internet web browser Mozilla Firefox announced that it plans on joining the fight against what it considers to be “fake news,” a term that to leftists means nothing more than news that is written by conservatives. Mozilla said that it was “investing in people, programs and projects” in an effort to “disrupt misinformation online.”

The first question that every constitutionalist and liberty-loving American should be asking is as follows: How does Mozilla define “fake news?” Are they only talking about suppressing radical websites such as sites run by white supremacists, or are they talking about any news that comes from conservatives? At the very least, it should worry you that companies like Mozilla are often reluctant to thoroughly define “fake news” – it is highly unlikely that this is unintentional.

Furthermore, what exactly gives Mozilla the right or the authority to determine what is misinformation and what is not? The United States Constitution is the law of the land, and the freedom of speech is an inalienable right from God. The fact that Mozilla thinks it has sweeping authority to select which speech is censored and which speech is not runs contrary to everything that America was founded upon.

With the assault on independent media getting increasingly aggressive, many Internet bloggers and website owners are desperately looking for ways they can continue voicing their opinions without being harassed, suppressed or silenced. If you are one of these people, you may want to consider using “Brave,” a relatively new web browser founded by former Mozilla CEO Brendan Eich.

On its website, Brave states that its goal is “to transform the online ad ecosystem with micropayments and a new revenue-sharing solution to give users and publishers a better deal, where fast, safe browsing is the path to a brighter future for the open web.”

Fortran Anonymous 08/29/2017 (Tue) 07:13:59 [Preview] No. 10930 [Reply] [Last 50 Posts]
Let's talk Fortran. It has been around since 1957, and has gone through numerous revisions. The first version was designed by John Backus at IBM. The most recent standard is Fortran 2008 (see attachment).

Fortran is reputed to be excellent for a number of science and math applications, from crunching numbers for weather simulations to linear algebra.

Here's one guy's take on Fortran as a modern computing language: https://bitbucket.org/eric_t/modern-fortran/wiki/Home

The example on that page compiles so fast with gfortran, even on my 2010-era system, that I thought there must have been some silent error when I compiled it, because it couldn't have compiled that fast. But, no, it was just that fast, even with bounds checking enabled.

Anyone else interested in Fortran here? Have any good tutorials? I've found _a lot_ of material about updating your skills from Fortran 77 to Fortran 90/95 or 2003/2008, but not much for the non-novice programmer who doesn't already do Fortran in some form.
