Your Old Phone Number Could Get You Hacked, Researchers Say

When you get a new phone number, mobile carriers will often “recycle” your old one—assigning it to a new phone and, therefore, a new customer. Carriers say the reason they do this is to stave off a hypothetical future of “number exhaustion”—a sort of “peak oil” for phone numbers, when every possible number that could…Read more...

Can YouTube Quiet Its Conspiracy Theorists?

Climate change is a hoax, the Bible predicted President Donald Trump's election and Elon Musk is a devil worshipper trying to take over the world.All of these fictions have found life on YouTube, the world's largest video site, in part because YouTube's own recommendations steered people their way.For years, it has been a highly effective megaphone for conspiracy theorists, and YouTube, owned and run by Google, has admitted as much. In January 2019, YouTube said it would limit the sp...

New Obstacle To Landing Job After College: Getting Approved By AI

(CNN) — College career centers used to prepare students for job interviews by helping them learn how to dress appropriately or write a standout cover letter. These days, they’re also trying to brace students for a stark new reality: They may be vetted for jobs in part by artificial intelligence. At schools such as Duke University, Purdue University, and the University of North Carolina at Charlotte, career counselors are now working to find out which companies use AI and also speaking candidly w...

How to recognize AI snake oil

Princeton computer scientist Arvind Narayanan (previously) has posted slides and notes from a recent MIT talk on "How to recognize AI snake oil" in which he divides AI applications into three (nonexhaustive) categories and rates how difficult they are, and thus whether you should believe vendors who claim that their machine learning models can perform as advertised. Narayanan's categories are: * Perception, such as facial recognition and song identification, where there is a definitive co...

Smart TVs Are Data-Collecting Machines, New Study Shows

A new study from Princeton University shows internet-connected TVs, which allow people to stream Netflix and Hulu, are loaded with data-hungry trackers. "If you use a device such as Roku and Amazon Fire TV, there are numerous companies that can build up a fairly comprehensive picture of what you're watching," Arvind Narayanan, associate professor of computer science at Princeton, wrote in an email to The Verge. "There's very little oversight or awareness of their practices, including where that ...

Bitcoin Mining Now Accounts For Almost One Percent of the World's Energy Consumption

It is well-established established that Bitcoin mining -- aka, donating one's computing power to keep a cryptocurrency network up and running in exchange for a chance to win some free crypto -- uses a lot of electricity. Companies involved in large-scale mining operations know that this is a problem, and they've tried to employ various solutions for making the process more energy efficient. But, according to testimony provided by Princeton computer scientist Arvind Narayanan to the Senate Commit...

What Actually Is Bitcoin? Princeton’s Free Course “Bitcoin and Currency Technologies” Provides Much-Needed Answers

"Don't Understand Bitcoin?" asked the headline of a recent video from Clickhole, the Onion's viral-media parody site. "This Man Will Mumble an Explanation at You." The inexplicable hilarity of the mumbling man and his 72-second explanation of Bitcoin contains, like all good humor, a solid truth: most of us don't understand Bitcoin, and the simplistic information we seek out, for all we grasp of it, might as well be delivered unintelligibly. A few years ago we featured a much clearer thre...

Scary But True: Hundreds of Popular Sites Log Everything You Type

Ever feel like your every move is being watched when you're online? Well, you're not just being paranoid. Nearly 500 of the top 50,000 Web sites on Alexa use so-called "session replay" scripts from third-party companies to record practically everything users do while visiting their sites, according to new research from a team at Princeton University. Among the activities being tracked and recorded are keystrokes, mouse movements, scrolling behavior, and content viewed from all the pages users ...

Third Party Trackers On Web Shops Can Identify Users Behind Bitcoin Transactions

An anonymous reader quotes a report from Help Net Security: More and more shopping websites accept cryptocurrencies as a method of payment, but users should be aware that these transactions can be used to deanonymize them -- even if they are using blockchain anonymity techniques such as CoinJoin. Independent researcher Dillon Reisman and Steven Goldfeder, Harry Kalodner and Arvind Narayanan from Princeton University have demonstrated that third-party online tracking provides enough information t...

Recapping the “Can Technology Rescue Democracy” Essay Series at The Atlantic

As I mentioned before, I helped organize a series of essays at The Atlantic addressing the question: “Is technology hurting our democracy, and can it help save it?” The series is now complete, so I thought it was worth revisiting the posts, many of which fit neatly into one of the following topic clusters: voting, journalism (including amateur content), privacy/surveillance, education, and platform responsibility. Here are brief excerpts from the 28 essays: * The Next Great Experiment: the intro...

New 'Perceptual' Ad Blocking Tech Doesn't Win The Ad Blocking War, But It May Put Advertisers On Their Heels... Permanently (techdirt)

We've long documented how there's a growing array of websites that seem intent on shooting themselves in the foot when it comes to "defeating" ad blocking. Quite often that includes punishing customers for a website's own misdeeds, or using ham-fisted (and frankly often broken) systems that attempt to block the ad blockers. Of course, this tends to obfuscate why these users are using blockers in the first place, whether it's to keep ads from eating their broadband usage allotments, or simply as ...

How surveillance capitalism tracks you without cookies

Princeton computer science researchers Steven Englehardt and Arvind Narayanan (previously) have just published a new paper, Online tracking: A 1-million-site measurement and analysis, which documents the state of online tracking beyond mere cookies -- sneaky and often illegal techniques used to "fingerprint" your browsers and devices as you move from site to site, tracking you even when you explicitly demand not to be track and take countermeasures to prevent this.

Your Battery Status Is Being Used To Track You Online (slashdot)

A paper published last year revealed that the battery on a laptop or phone can be used to track one's online activities. The vulnerability resided in a built-in HTML 5 specification, which could be tricked into identifying people and tracking their online activities. One year later, we are now learning that the vulnerability is being exploited in the wild. The Guardian reports: [...] Two security researchers from Princeton University have shown that the battery status indicator really is being u...

Your device’s battery status can be used to track you online

There are a myriad of ways you can be tracked online – from supercookies, to canvas fingerprinting and malware. Now you can add your device’s battery status to the list, according to research by Steve Engelhard and Arvind Narayanan – two academics from Stanford University. The attack takes advantage of the HTML5 Battery Status API, which allows servers to determine when they need to send an energy-efficient version of a website. It lets them see how much charge a laptop, tablet, or smartphone ha...
