Submission + - Acoustic cryptanalysis (tau.ac.il)

DaBunny writes: From the summary:

Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.

Submission + - BlackBerry posts $4.4 billion loss, outsourcing to Foxconn (www.cbc.ca)

iONiUM writes: Today BlackBerry announced a $4.4 billion loss, and a deal with Foxconn to outsource hardware manufacturing. One interesting stat is that 75% of sales were actually older BB7 devices. That said, CEO John Chen says "We are very much alive, thank you." as well as "Our 'for sale' sign has been taken down and we are here to stay. BlackBerry recently announced it has entered into an agreement to receive a strategic investment from Fairfax Financial and other institutional investors, which represents a vote of confidence in the future of BlackBerry."

Submission + - Microsoft Security Essentials misses 39% of malware (pcpro.co.uk)

Barence writes: The latest tests from Dennis Publishing's security labs saw Microsoft Security Essentials fail to detect 39% of the real-world malware thrown at it. Dennis Technology Labs (DTL) tested nine home security products on a Windows 7 PC, including Security Essentials, which is distributed free to Windows users and built into Windows 8 in the form of Windows Defender. While the other eight packages all achieved protection scores of 87% or higher — with five scoring 98% or 99% — Microsoft's free antivirus software protected against only 61% of the malware samples used in the test. Microsoft conceded last year that its security software was intended to offer only "baseline" performance".

Submission + - BitTorrent Unveils Secure Chat to Counter 'NSA Dragnet Surveillance'

Hugh Pickens DOT Com writes: Jacob Kastrenakes reports on The Verge that as part a response to the NSA's wide-reaching surveillance programs, BitTorrent is unveiling a secure messaging service that will use public key encryption, forward secrecy, and a distributed hash table so that chats will be individually encrypted and won't be stored on some company's server. "It’s become increasingly clear that we need to devote hackathons, hours and resources to developing a messaging app that protects user privacy," says Christian Averill, BitTorrent's director of communications. Because most current chat services rely on central servers to facilitate the exchange of messages, "they're vulnerable: to hackers, to NSA dragnet surveillance sweeps." BitTorrent chat aims to avoid those vulnerabilities through its encryption methods and decentralized infrastructure. Rather than checking in with one specific server, users of BitTorrent chat will collectively help each other figure out where to route messages to. In order to get started chatting, you'll just need to give someone else your public key — effectively your identifier. Exchanging public keys doesn't sound like the simplest way to begin a chat, but Averill says that BitTorrent hopes to make it easy enough for anyone interested. "What we're going to do is to make sure there are options for how this is set up," says Averill. "This way it will appeal to the more privacy conscious consumer as well as the less technically inclined." For now, it remains in a private testing phase that interested users can apply for access to. There's no word on when it'll be open to everyone, but with all of the recent surveillance revelations, it's easy to imagine that some people will be eager to get started.

As an owner of a refurbished Thinkpad - from a German reseller of used laptops, not the company mentioned in the story - I can assure you that any old Thinkpad with GNU/Linux just works. Older Thinkpads are among the laptops with the best Linux support you can find. I use mine every day for 8 hours for years (and before that I used another old Thinkpad for years).

Regarding the other thing you mention, to be honest I have to admit that I have no idea what "value added" means. I've heard it occasionally but always though it was more like a meaningless buzzword or (worse) a synonym for pre-installed bloatware. What does it mean?

Submission + - Billion Star Surveyor 'Gaia' Lifts Off

mrspoonsi writes: BBC Reports: Europe has launched the Gaia satellite — one of the most ambitious space missions in history. The 740m-euro (£620m) observatory lifted off from the Sinnamary complex in French Guiana at 06:12 local time (09:12 GMT). Gaia is going to map the precise positions and distances to more than a billion stars. This should give us the first realistic picture of how our Milky Way galaxy is constructed. Gaia's remarkable sensitivity will lead also to the detection of many thousands of previously unseen objects, including new planets and asteroids. Gaia will use this ultra-stable and supersensitive optical equipment to pinpoint its sample of stars with extraordinary confidence. By repeatedly viewing its targets over five years, it should get to know the brightest stars' coordinates down to an error of just seven micro-arcseconds. "This angle is equivalent to the size of a euro coin on the Moon as seen from Earth," explained Prof Alvaro Gimenez, Esa's director of science.

Jesus Christ, take it easy, man. I was making a harmless joke that anyone who was ever forced to watch boring holiday slideshows would be able to understand. Now I'm being accused of mental health issues, not being able to procreate and whatever else.

If hundreds of thousands of family pictures doesn't seem a bit excessive to you, so be it. After all, it takes only a few weeks to sort through them. But please calm down a little and stop spamming AC troll posts.

Yes, you've got to save them! Your children will be so thankful for countless extended family diashow evenings!

I am a positive atheist. To me personally the first four are slightly annoying (aggressive and discriminating other religions), the seventh is plain ridiculous, and the tenth unneccessary.

But yeah, I'm not offended by a monument with them. I can imagine worse kind of monuments, and in a place where many people are Christians, why not? I'd put a statue of Charles Darwin right next to it, though, just to set things straight.

I never log in and don't think I see any results tailored to me, but now I'm wondering whether that's actually true.

You'll never really know will you?

Isn't that testable? Set up two identical browsers on two geographically close machines, make them perform a series of differing and clearly biased searches (e.g. about a political topic or shopping preference) and compare the results of one and the same query from both machines after a few days or weeks.

I was hoping somebody did that already...
