My browser visited Drudgereport and all I got was this lousy malware

Millions of people visiting drudgereport.com, wunderground.com, and other popular websites were exposed to attacks that can surreptitiously hijack their computers, thanks to maliciously manipulated ads that exploit vulnerabilities in Adobe Flash and other browsing software, researchers said. The malvertising campaign worked by inserting malicious code into ads distributed by AdSpirit.de, a network that delivers ads to Drudge, Wunderground, and other third-party websites, according to a post published Thursday by researchers from security firm Malwarebytes. The ads, in turn, exploited security vulnerabilities in widely used browsers and browser plugins that install malware on end-user computers. The criminals behind the campaign previously carried out a similar attack on Yahoo’s ad network , exposing millions more people to the same drive-by attacks. Malvertising is a particularly pernicious form of attack because it can infect people who do nothing more than browse to a mainstream site. Depending on the exploit, it can silently hijack computers even when visitors don’t click on links. Some browser makers have responded by implementing so-called click-to-play mechanisms that don’t render Flash or Java content unless the end user actively permits the plugin to run on a particular site. Some users have resorted to ad blockers, which have the unfortunate side effect of depriving publishers of much-needed advertising revenue. Read 1 remaining paragraphs | Comments

Facebook user gets away with nearly a full day of trolling Target commenters

Mike Melgaard 9 more images in gallery While Facebook facilitates plenty of interaction between big companies and their customers, its interface doesn’t scale incredibly well once company-page comments creep into the hundreds (or more) per day. In particular, “comments by users” on a company page are relegated to a sidebar that is pretty hard to parse. On Sunday, one intrepid Facebook user took advantage of that to sneak onto a company page and mess with commenters before the company could get wise to it—and lucky for us, he screencapped the whole thing. This week’s case came from American retailer Target, whose Facebook feed began to blow up with unhappy comments over the weekend after the company announced plans to remove gender-specific signs in departments such as Toys and Entertainment. The retailer didn’t get around to individually responding to commenters, but that didn’t stop a user from creating a new account on Sunday, giving it a Target-styled bullseye icon and pretending to be an official company spokesperson. That user, Scottsdale, Arizona, resident Mike Melgaard , went on to respond to at least 52 negative comments left on Target’s official Facebook page with an account named “Ask ForHelp,” but rarely were his responses helpful . Melgaard heaped on sarcastic smiley faces, grammatical criticisms, and jokes about doing away with all gender-specific labels at the store (including bathrooms and changing rooms). It’s hard to pick a favorite among the jokes—we’ve posted a few of its safe-for-work screencaps above—but our favorite might be when he got into a multiple-comment conversation with one complainer, which he ended with a phony exclamation that it was his “first day, and this is just really frustrating dealing with all of this!” Read 2 remaining paragraphs | Comments

Xbox streaming on Windows 10 has a hidden “very high quality” setting

In reviewing Windows 10’s new “Streaming from Xbox 10” feature , Ars’ Sam Machkovech complained that “streamed Xbox One games look significantly worse through Windows 10, even at the highest-quality setting.” Apparently, though, Sam wasn’t actually testing the “highest quality” setting available in the streaming app. That’s because there’s a newly uncovered “very high quality” option that can be unlocked by tinkering with some of the Xbox app’s configuration files. Reddit user OomaThurman has publicized the method for unlocking this hidden quality setting, which involves editing the “userconsoledata” file in your Xbox app folder. You can activate the new higher-quality setting by setting the “IsInternalPreview” flag from “false” to “true,” a naming convention that strongly suggests this feature is part of an early test that will be formally rolled out to all Windows 10 users in the future. We’ll be trying out this hidden feature for ourselves soon, but the folks at Digital Foundry already found a marked jump in quality when using the “very high” setting, saying it “appears to transmit full 1080p imagery.” Comparison shots published by Digital Foundry show a noticeable increase in sharpness of details like faces, hair, and edges, which are much closer to the “source” image with the new setting.

Snapdragon 820 is official: A look at its GPU (and how much the chip matters)

Qualcomm’s Snapdragon 810 and 808 will continue to be its flagship chips for the rest of this year, but, as we’ve written, the 810 in particular has been problematic for the company. It had a gift for generating both heat and bad press , and, while the Snapdragon 808 didn’t suffer from the same problems, it was less of an improvement over older 800-series chips. As this has been happening on the technical side, things have been looking less rosy on the financial side. Qualcomm’s outlook for Q4 of 2015 ( PDF ) sums it up nicely: there’s “increased concentration” at the high end of the market, pushing out phones that use Snapdragon SoCs (the huge worldwide success of the iPhone 6 and 6 Plus can be at least partially blamed); “lower demand” for high-end Snapdragons from one of Qualcomm’s major customers (read: Samsung, which is using its own chips in high-end Galaxy phones); and lowered sales of “certain handset models” in China using high-end Snapdragons. Some of this could be attributed to the 810 specifically, but a lot of it would be happening no matter how good the chip was. Most of the money in consumer electronics is in high-end, high-margin products, but Apple controls an overwhelming amount of that market , and the company only uses Qualcomm’s modems, not the (presumably more expensive and profitable) Snapdragon SoCs. The wider smartphone market continues to grow, but companies like Xiaomi and Motorola are willing to sell to good-to-great phones for one-third to one-half of what you’d pay for a flagship, and those phones often use lower-end, less-profitable Qualcomm SoCs or chips from an upstart like MediaTek or a newly competitive Intel.

Smach Zero: A portable x86 Steam Machine for $300

Even the most hardened of Valve fans would be hard pressed to call the company’s Steam Machine initiative particularly exciting. After all, with the exception of Alienware’s Alpha or Asus’ ROG, most of them are simply glorified tower PCs, rather than innovative pieces of console-like design. Today, however, that all changes with the Smach Zero, an x86-based portable Steam Machine that promises access to the 1000+ SteamOS games in Valve’s library. The Smach Zero is powered by an AMD G-Series SoC named Steppe Eagle, which features a Jaguar-based CPU paired with a GCN-based GPU. We don’t know which G-Series SoC is actually being used, but presumably it’ll be one of the 6W or 9W TDP parts (PDF). The CPU is probably clocked somewhere around 1GHz, and the GPU between 200-300MHz (roughly equivalent to an HD 8210E). Along with the SoC, there’s 4GB of RAM, 32GB of storage (expandable via an SD card slot), a 5-inch 720p touchscreen, HDMI output, WiFi, and Bluetooth. On the front of the Smach Zero there are “configurable tactile gamepads,” which look suspiciously like the ones that Valve initially had on the Steam Controller before its redesign.

Last New Zealand coal plant reaches the end of the line

Yesterday, one of New Zealand’s major energy producers announced that it is planning on shuttering the last of the country’s coal-fired power stations in 2018. The plant’s extended life comes despite the fact that running it has become economically marginal—the company that runs it says it is locked into a coal delivery contract until mid-2017 and has substantial stockpiles on site. New Zealand is fortunate to have abundant renewable energy sources, including a number of large hydroelectric plants. Fossil fuels have mostly been used to supplement the hydroelectric production during years of lower rainfall. But the country has also benefitted from trends that are seen in most other industrialized nations. Energy demand has largely been stable due to increased efficiency, while the cost of other renewable power sources has dropped. In New Zealand’s case, those new sources are wind and geothermal (part of the country sits atop a subduction zone). As the costs of developing wind and geothermal have dropped, the coal fired plant was being used less frequently. “These units have largely been operating at the margin of the market for a number of years, at very low utilisation rates,” said company CEO Albert Brantley. Shuttering them is expected to save the company over NZ$20 million a year. Read 1 remaining paragraphs | Comments

A new polymer that can boost capacitors

From hybrid and electric vehicles to underground exploration of fossil-fuels, our search for energy solutions has increasingly placed us in situations demanding electricity storage and delivery under extreme conditions. Though batteries are the reigning storage technology, capacitors are an alternative with several advantages: they’re lightweight, they can be charged and discharged relatively quickly, and they don’t lose their storage capacity over time. In order to function properly, capacitors require dielectric materials, which behave as insulators and are essential for charge storage. Polymeric dielectrics have enhanced performance over other materials, and they can operate under more intense electric fields without failing (termed higher breakdown strength) and greater reliability. They also have the added benefit of practicality, being scalable, lightweight, and easily manipulated. Right now, their major drawback as a material is their inability to work at high temperatures, like those required in many applications. But a composite polymer has finally been developed that seems to break down the traditional limitations of these materials, promising to open up a broader range of uses. Scientists made the new material by crosslinking a traditional polymer embedded with flakes of boron nitride nano sheets. Read 12 remaining paragraphs | Comments

Where broadband is a utility, 100Mbps costs just $40 a month

There’s been a lot of debate over whether the United States should treat Internet service as a utility . But there’s no question that Internet service is already a utility in Sandy, Oregon, a city of about 10,000 residents, where the government has been offering broadband for more than a decade. “ SandyNet ” launched nearly 15 years ago with DSL and wireless service, and this summer it’s putting the final touches on a citywide upgrade to fiber. The upgrade was paid for with a $7.5 million revenue bond, which will be repaid by system revenues. Despite not being subsidized by taxpayer dollars, prices are still low: $40 a month for symmetrical 100Mbps service or $60 a month for 1Gbps. There are no contracts or data caps. “Part of the culture of SandyNet is we view our citizens as owners of the utility,” City IT Director and SandyNet GM Joe Knapp told Ars in a phone interview. “We’ve always run the utility on a break-even basis. Any profits we do have go back into capital improvements and equipment upgrades and things like that.” Read 34 remaining paragraphs | Comments

NSA report shows China hacked 600+ US targets over 5 years

NBC has released a 2014 slide from a secret NSA Threat Operations Center (NTOC) briefing—a map that shows the locations of “every single successful computer intrusion” by Chinese state-sponsored hackers over a five-year period. Over 600 US businesses and institutions were breached during that period. The slide was provided to NBC by an unnamed “intelligence source,” who said the briefing “highlighted China’s interest in Google and defense contractors like Lockheed Martin, and in air traffic control systems… [and] catalogued the documents and data Chinese government hackers have exfiltrated,” the network reported. The report suggests that the NSA has been tracking Chinese cyber-attacks for years and that its own network surveillance of China gives the agency the ability to correlate those attacks with specific sources. The briefing shown to NBC listed locations for the sources of each of the “exploitations and attacks,” NBC reported. Read 5 remaining paragraphs | Comments

Sony’s profits triple as PS4 sales reach 25 million units worldwide

Sony’s profits have more than tripled year-on-year in the April to June quarter ( PDF link ), thanks to strong sales of camera sensors and the PlayStation 4, which has now sold 25.3 million units globally to date. The company’s overall net profit rose to ¥82.4 billion yen (£425 million, $664 million), significantly surpassing market expectations. Sony moved three million PS4s during the quarter, while peripheral and software shipments also increased, leading to the division’s 12.1 percent increase in sales to ¥288.6 billion (£1.4 billion, $2.3 billion), and an operating profit of ¥19.5 billion (£100 million, $160 million). The PS4 has taken a significant lead in the console market, massively outselling the rival Xbox One and Nintendo Wii U, the latter of which has sold just 10 million units . Sony’s devices division—which makes the camera sensors in high-end phones from Samsung and Apple— continues to grow . The unit saw a 35.1 percent increase in sales to ¥237.9 billion (£1.2 billion, $2 billion). Sales to external customers—i.e., those high-end phone makers—increased 41.2 percent year-on-year.
