Submission + - Sniffing and decoding NRF24L01+ and Bluetooth LE packets for under $30 (cyberexplorer.me)

An anonymous reader writes: I was able to decode NRF24L01+ and Bluetooth Low Energy protocols using RTL-SDR.
As far as I can see, this is the first time the NRF24L01+ is being decoded, especially considering the low entry price for the hardware. Given the extreme popularity of this transceiver, we are likely to see a wave of hackers attacking the security of many wireless gadgets, and they are likely to succeed as security is usually the last priority for hardware designers of such cheap gadgets.

A lot of work have been done to decode bluetooth using dedicated hardware and I am sure this software can be adapted to output the right format as input to the existing Bluetooth decoders such as Wireshark.
As far as I can see, this is also the first time BTLE can be decoded using a very cheap generic device.

Submission + - Tweets And Threats: Gangs Find New Home On The Net (ap.org)

cold fjord writes: Associated Press reports, "Social media has exploded among street gangs ... They're turning to Twitter, Facebook, YouTube and Instagram to flaunt guns and wads of cash, threaten rivals, intimidate informants ... sell weapons, drugs — even plot murder. "What's taking place online is what's taking place in the streets," says David Pyrooz, an assistant professor at Sam Houston State University ... "The Internet does more for a gang's brand or a gang member's identity than word-of-mouth could ever do. It really gives the gang a wide platform to promote their reputations. ... On the crime-fighting side ... this activity ... is transforming how police and prosecutors pursue gangs. Along with traditional investigative techniques, police monitor gangs online ... a Cincinnati police officer who trains other law enforcement about social media, says by the time gang members appear in court, authorities have a dossier of their words and videos online that challenge how they want to portray themselves. "If a guy goes in and says, `I'm a good person. I've never held a gun,' we can say, `Look at what he puts out about himself on social media. Here he is with a gun.' ..." ... police say monitoring social media is time-consuming and frustrating."

Submission + - How Chris Christie Could Use the NSA Playbook to Defend Himself over Bridgegate

Hugh Pickens DOT Com writes: Conor Friedersdorf has written a tongue-in-cheek article in The Atlantic advising New Jersey Governor Chris Christie how he can use the NSA playbook to successfully defend himself of the charges that a senior member of his staff was involved in shutting down George Washington Bridge traffic, a stunt meant to punish the mayor of an affected town for opposing his reelection. Christie's NSA-inspired explanation would include the following points: There are almost 9 million people in New Jersey, and only one was targeted for retribution, an impressively tiny error rate lower than .001 percent; The bridge closure was vital to national security because [redacted]; Since the George Washington Bridge is a potential terrorist target, everything that may or may not have happened near it is a state secret; Going after a political rival is wrong but it's important to put this event in context; Fort Lee Mayor Mark Sokolich was the only target of non-compliant behavior. No other Fort Lee resident was ever targeted for retribution, and any delays that any Fort Lee resident experienced were totally inadvertent and incidental; Finally a panel will be formed to figure out how to restore the public's faith in Chris Christie. "To some readers, these talking points may seem absurd or deliberately misleading," concludes Friedersdorf, "but there isn't any denying that so far they're working okay for the NSA."

Submission + - New class of "hypervelocity stars" discovered escaping the galaxy (vanderbilt.edu)

Science_afficionado writes: Astronomers have discovered a surprising new class of “hypervelocity stars” that are moving at more than a million miles per hour, fast enough to escape the gravitational grasp of the Milky Way galaxy. The 20 hyper stars are about the same size as the sun and, other than their extreme speed, have the same composition as the stars in the galactic disk. The big surprise is that they don't seem to come from the galaxy's center. The generally accepted mechanism for producing hypervelocity stars relies on the extreme gravitational field of the supermassive black hole that resides in the galaxy's core. So the discovery means that astrophysicists must come up with an entirely new method for speeding stars to hypervelocities.

It will be a revelation to senior management.

They will in fact need reports such as this to recognize the reality that all us IT workers have known for years.

Yeah, right. Senior management will never read a report titled "Senior managers are the worst information security offenders" on a site called net-security.org, any more than they would read a report at motherjones.com about the disparity between the wages of regular employees and executives.

I pay to use the Internet already via my ISP.

I block ads too, but it's a bit of a non sequitur to say that there is no need to support the sites you visit because you pay your ISP for access to the Internet. It's not like you ISP is passing any of that money along to the producers of the content on the sites you visit.

I pay taxes to local governments responsible for maintaining our roads. That doesn't mean GM owes me a car.

You, sir, should read the next paragraph in the Wikipedia article you linked to:

A customer may or may not also be a consumer, but the two notions are distinct, even though the terms are commonly confused. A customer purchases goods;

That would be advertisers paying money to Facebook in exchange for your data so they can target ads at you

a consumer uses them.

That would be you clicking Like on that Miley Cyrus video, generating the data (the product) that the advertisers are willing to pay Facebook for.

An ultimate customer may be a consumer as well, but just as equally may have purchased items for someone else to consume.

That would be the advertisers (the customer) providing the revenue Facebook requires to provide the service to you (the consumer).

I already covered this in my previous comment, but maybe I failed to make myself clear. Yes, Facebook users exchange their data for the use of the service, but their data in and of itself is of minimal value to Facebook. Sure, it may give them opportunities to expand their user-base, for example. Especially if you are willing to allow them to harvest the contacts in your email client.

It is the advertisers who value you data, and are willing to exchange money for it. That provides the revenue Facebook needs to keep operating.

You are providing a resource to Facebook in return for the use of their service, which they then refine and sell to their customers. It's no different than the farmer who grows the potatoes that McDonald's turns in to french fries, except the farmer is probably being paid in cash rather than cat videos.

Is the farmer the customer?

Here's a better analogy, and it even has a car in it:

I'm a high school kid and my dad runs a used car lot. I come in after school and on weekends and wash cars on the lot so they will be more appealing to my dad's customers. He doesn't pay me, because I'm his kid and he's a cheapskate, but in exchange for my efforts he occasionally lets me drive one of the cars from the lot.

So I'm giving something that is of limited value on it's own, but increases my dad's ability to generate revenue for his car lot so it can stay in business, and in return receive the use of some of the company's assets.

Now substitute washing cars with clicking Like buttons, and using cars from the lot with using the site, and you begin to get the picture. The fact that I exchanged a bit of labour for the occasional use of a car from the lot does not make me the customer. I'm more like a supplier, or a sub-trade even.

But I'm sure I'm not changing your mind about anything, if you've even bothered to read this far. If you want to think of yourself as Facebook's customer, go right ahead. But your use of their site on its own generates no revenue, and without revenue a company isn't viable. In my book the actor providing the revenue is the customer. They are the ones my business will cater to.

Having someone wash the cars on my lot is great, and might even help my business, but without cash-paying customers my business will fail.

Wow, I can understand your frustration.

Users restarting their machines to get around the virus scan is an issue for their supervisor to address. Hammering them with back-to-back scans only increases their frustration and the likelihood that they will continue to look for ways to defeat the process.

Battles between IT and users are common, and we've had to lock down some of the machines at my company to stop bad behavior, but it really sounds like things have progressed to the point where your IT department is simply being obstinate. Yes, it's important that the scans complete, but if your users can not do their jobs for six or seven hours of every week, pretty soon there will be no point in scanning the machines. You'll be out of business.

Most people in my office don't even come in on Tuesdays anymore because that's virus scan day. It starts a 1AM and nothing on your machine will work until at least 3PM

If it is actually taking 14 hours to complete a virus scan, I would be looking for other issues with the hardware. Seriously, 14 hours? We use McAfee VirusScan Enterprise where I work, and most full system scans complete within an hour or so. If you weren't exaggerating, your security group must be truly incompetent as that is beyond acceptable.

As a workaround, depending on your office hours you could begin the scans at 6:00 PM instead of 1:00 AM, so they would be finished by 8:00 the following morning. That won't solve the mystery as to why your scans are taking so long, but at least the people in your office could start coming in on Tuesdays again.

Company have multiple types of customers. Hint: Facebook's users ARE customers.

Accepting for the moment that company (sic) have multiple types of customers, the most important "type" would be the one who is paying the bills. And that certainly isn't the user.

Honestly, read a book or something. The idea that the consumers of online services are the product, not the customer, is neither new or particularly controversial. You could argue, and I suppose you are, that the user is paying for the services received by providing personal information in exchange for the service, but that would make them more like a supplier of raw material (their "likes," their social connections etc) that is then processed and re-sold to advertisers who use that information target ads at the users.

The ultimate customer is the purchaser of those ads, regardless of whether you feel you received something of value in exchange for the information you provided.

Just because they aren't buying anything doesn't mean they aren't customers. You have a lot to learn about business

My business provides services to clients on behalf of other businesses. We work hard to ensure that the consumers of those services are happy and never forget how important they are to the viability of our business, but they are not customers, they are clients. Our customers are the businesses who pay us to provide those services to their customers, our clients.

If you can provide examples of businesses that remained viable despite their customers not buying anything, then I will defer to your obviously superior business knowledge.
