Researcher Turns HDD Into Rudimentary Microphone

An anonymous reader writes from Bleeping Computer: Speaking at a security conference, researcher Alfredo Ortega has revealed that you can use your hard disk drive (HDD) as a rudimentary microphone to pick up nearby sounds. This is possible because of how hard drives are designed to work. Sounds or nearby vibrations are nothing more than mechanical waves that cause HDD platters to vibrate. By design, a hard drive cannot read or write information to an HDD platter that moves under vibrations, so the hard drive must wait for the oscillation to stop before carrying out any actions. Because modern operating systems come with utilities that measure HDD operations up to nanosecond accuracy, Ortega realized that he could use these tools to measure delays in HDD operations. The longer the delay, the louder the sound or the intense the vibration that causes it. These read-write delays allowed the researcher to reconstruct sound or vibration waves picked up by the HDD platters. A video demo is here. “It’s not accurate yet to pick up conversations, ” Ortega told Bleeping Computer in a private conversation. “However, there is research that can recover voice data from very low-quality signals using pattern recognition. I didn’t have time to replicate the pattern-recognition portion of that research into mine. However, it’s certainly applicable.” Furthermore, the researcher also used sound to attack hard drives. Ortega played a 130Hz tone to make an HDD stop responding to commands. “The Linux kernel disconnected it entirely after 120 seconds, ” he said. There’s a video of this demo on YouTube.

Half the Universe’s Missing Matter Has Just Been Finally Found

An anonymous reader shares a report: The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe — protons, neutrons and electrons — unaccounted for by previous observations of stars, galaxies and other bright objects in space. You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far. Two separate teams found the missing matter — made of particles called baryons rather than dark matter — linking galaxies together through filaments of hot, diffuse gas. “The missing baryon problem is solved, ” says Hideki Tanimura at the Institute of Space Astrophysics in Orsay, France, leader of one of the groups. The other team was led by Anna de Graaff at the University of Edinburgh, UK. Because the gas is so tenuous and not quite hot enough for X-ray telescopes to pick up, nobody had been able to see it before. Read more of this story at Slashdot.

Russian Hackers Exploited Kaspersky Antivirus To Steal NSA Data on US Cyber Defense: WSJ

An NSA contractor brought home highly classified documents that detailed how the U.S. penetrates foreign computer networks and defends against cyberattacks. The contractor used Kaspersky antivirus on his home computer, which hackers working for the Russian government exploited to steal the documents, the WSJ reported on Thursday (the link could be paywalled; alternative source), citing multiple people with knowledge of the matter. From the report: The hackers appear to have targeted the contractor after identifying the files through the contractor’s use of a popular antivirus software made by Russia-based Kaspersky Lab, these people said. The theft, which hasn’t been disclosed, is considered by experts to be one of the most significant security breaches in recent years. It offers a rare glimpse into how the intelligence community thinks Russian intelligence exploits a widely available commercial software product to spy on the U.S. The incident occurred in 2015 but wasn’t discovered until spring of last year, said the people familiar with the matter. Having such information could give the Russian government information on how to protect its own networks, making it more difficult for the NSA to conduct its work. It also could give the Russians methods to infiltrate the networks of the U.S. and other nations, these people said. Ahead of the publication of WSJ report, Kaspersky founder Eugene Kaspersky tweeted, “New conspiracy theory, anon sources media story coming. Note we make no apologies for being aggressive in the battle against cyberthreats.” Read more of this story at Slashdot.

According To Star Trek: Discovery, Starfleet Still Runs Microsoft Windows

AmiMoJo shares a report from The Verge: The third episode of Star Trek: Discovery aired this week, and at one point in the episode, Sonequa Martin-Green’s Michael Burnham is tasked with reconciling two suites of code. In the show, Burnham claims the code is confusing because it deals with quantum astrophysics, biochemistry, and gene expression. And while the episode later reveals that it’s related to the USS Discovery’s experimental new mycelial network transportation system, Twitter user Rob Graham noted the code itself is a little more pedestrian in nature. More specifically, it seems to be decompiled code for the infamous Stuxnet virus, developed by the United States to attack Iranian computers running Windows. Read more of this story at Slashdot.

We’re Not Living in a Computer Simulation, New Research Shows

A reader shares a report: A team of theoretical physicists from Oxford University in the UK has shown that life and reality cannot be merely simulations generated by a massive extraterrestrial computer. The finding — an unexpectedly definite one — arose from the discovery of a novel link between gravitational anomalies and computational complexity. In a paper published in the journal Science Advances, Zohar Ringel and Dmitry Kovrizhi show that constructing a computer simulation of a particular quantum phenomenon that occurs in metals is impossible — not just practically, but in principle. The pair initially set out to see whether it was possible to use a technique known as quantum Monte Carlo to study the quantum Hall effect — a phenomenon in physical systems that exhibit strong magnetic fields and very low temperatures, and manifests as an energy current that runs across the temperature gradient. The phenomenon indicates an anomaly in the underlying space-time geometry. They discovered that the complexity of the simulation increased exponentially with the number of particles being simulated. If the complexity grew linearly with the number of particles being simulated, then doubling the number of partices would mean doubling the computing power required. If, however, the complexity grows on an exponential scale — where the amount of computing power has to double every time a single particle is added — then the task quickly becomes impossible.

Ancient Papyrus Finally Solves Egypt’s ‘Great Pyramid’ Mystery

schwit1 was the first Slashdot reader to bring us the news. Newsweek reports: Archaeologists believe they have found the key to unlocking a mystery almost as old as the Great Pyramid itself: Who built the structure and how were they able to transport two-ton blocks of stone to the ancient wonder more than 4, 500 years ago…? Experts had long established that the stones from the pyramid’s chambers were transported from as far away as Luxor, more than 500 miles to the south of Giza, the location of the Great Pyramid, but had never agreed how they got there. However, the diary of an overseer, uncovered in the seaport of Wadi al-Jafr, appears to answer the age-old question, showing the ancient Egyptians harnessed the power of the Nile to transport the giant blocks of stone. According to a new British documentary Egypt’s Great Pyramid: The New Evidence, which aired on the U.K.’s Channel 4 on Sunday, the Great Pyramid, also known as the Pyramid of Khufu, was built using an intricate system of waterways which allowed thousands of workers to pull the massive stones, floated on boats, into place with ropes. Along with the papyrus diary of the overseer, known as Merer, the archaeologists uncovered a ceremonial boat and a system of waterworks. The ancient text described how Merer’s team dug huge canals to channel the water of the Nile to the pyramid. Read more of this story at Slashdot.

Chicago School Official: US IT Jobs Offshored Because ‘We Weren’t Making Our Own’ Coders

theodp writes: In a slick new video, segments of which were apparently filmed looking out from Google’s Chicago headquarters giving it a nice high-tech vibe, Chicago Public Schools’ CS4ALL staffers not-too-surprisingly argue that creating technology is “a power that everyone needs to have.” In the video, the Director of Computer Science and IT Education for the nation’s third largest school district offers a take on why U.S. IT jobs were offshored that jibes nicely with the city’s new computer science high school graduation requirement. From the transcript: “People still talk about it’s all offshored, it’s all in India and you know, there are some things that are there but they don’t even realize some of the reasons that they went there in the first place is because we weren’t making our own.” Read more of this story at Slashdot.

Nestle Makes Billions Bottling Water It Pays Nearly Nothing For

Nestle, the world’s largest food and beverage company, has been bottling water since 1843 and has grown into the largest seller of bottled water. But a detailed report on Bloomberg uncovers the company’s operation in Michigan, revealing that Nestle has come to dominate in the industry in part by going into economically depressed areas with lax water laws. It makes billions selling a product for which it pays close to nothing. Find the Bloomberg Businessweek article here (it might be paywalled, here’s an alternative source).

Ransomware Hack Targeting 2 Million an Hour

New submitter Zorro writes: A ransomware attack sweeping the globe right now is launching about 8, 000 different versions of the virus script at Barracuda’s customers, Eugene Weiss, lead platform architect at Barracuda, told Axios, and it’s hitting at a steady rate of about 2 million attacks per hour. What to watch out for: An incoming email spoofing the destination host, with a subject about “Herbalife” or a “copier” file delivery. Two of the latest variants Barracuda has detected include a paragraph about legalese to make it seem official, or a line about how a “payment is attached, ” which tricks you to click since, as Weiss puts it, “everyone wants a payment.” Read more of this story at Slashdot.

Every Major Advertising Group Is Blasting Apple for Blocking Cookies in the Safari Browser

The biggest advertising organizations say Apple will “sabotage” the current economic model of the internet with plans to integrate cookie-blocking technology into the new version of Safari. Marty Swant, reporting for AdWeek: Six trade groups — the Interactive Advertising Bureau, American Advertising Federation, the Association of National Advertisers, the 4A’s and two others — say they’re “deeply concerned” with Apple’s plans to release a version of the internet browser that overrides and replaces user cookie preferences with a set of Apple-controlled standards. The feature, which is called “Intelligent Tracking Prevention, ” limits how advertisers and websites can track users across the internet by putting in place a 24-hour limit on ad retargeting. In an open letter expected to be published this afternoon, the groups describe the new standards as “opaque and arbitrary, ” warning that the changes could affect the “infrastructure of the modern internet, ” which largely relies on consistent standards across websites. The groups say the feature also hurts user experience by making advertising more “generic and less timely and useful.” Read more of this story at Slashdot.
