BitLocker, PGP and TrueCrypt encryption weakened by new attack tool

BitLocker, PGP and TrueCrypt encryption weakened by new attack tool | digitalcuration | Scoop.it

Russian password-cracking wizards ElcomSoft have announced a new product that can retrieve decryption keys for BitLocker, PGP and open source favourite TrueCrypt as long as the encrypted volumes were not securely demounted.

As chinks in the armour of such encryption systems go the one exploited by Forensic Disk Decryptor is small but potentially useful to forensic engineers in some circumstances.

Normally, a volume (or smaller container) encrypted by one of these software programs is secured using a password, which can't be broken using any known brute-forcing attack as long as it is long and complex enough.

However, according to Elcomsoft when this password has been entered and the volume 'opened' the keys to access the volume and its files are kept in memory as 'dumps or (where the PC has entered hibernation), as 'hibernation' files.

These temporary files allow access to the key used to secure the volumes if the target PC is discovered in its powered state or in a state of hibernation. Files can also be retrieved from a system that has been turned off as long as the PC entered hibernation while the volume was open prior to being

In summary, files encrypted with BitLocker, PGP and Truecrypt are safe from this product as long as volumes are opened or mounted and then closed and demounted in an orderly way; doing this destroys the insecure memory dump. For extra safety, hibernation should be disabled.

How Facebook Is Hunting Down And Deleting Fake Accounts

How Facebook Is Hunting Down And Deleting Fake Accounts | digitalcuration | Scoop.it

Earlier this year, in its Q2 2012 earnings report, Facebookdisclosed that 4.8 percent of its accounts were either "duplicate" accounts (meaning that one person was operating more than one profile) or being used for nefarious purposes that violate Facebook's rules.

In Q3, however, Facebook didn't give an update on its efforts to drive down the rate of fake accounts — and the fake "Likes" that they seem to generate. Facebook's war against fakes is a work in progress, it seems. The company is due to report new numbers after Dec. 31.

The fake like/fake account issue has been a years long headache at Facebook. Even though the actual rate of questionable activity on Facebook is a small percentage of its entire traffic, it harms the social network's reputation.

 

Facebook has been sued over invalid clicks in the past. There are persistent reports of fake likes coming from the accounts of deceased friends. The system has had flaws in it in the past that have inflated the number of likes on a page. And in October, Facebook began a purge of fake accounts and the likes they generated.

 

So we asked Facebook's vp/global marketing solutions Carolyn Everson what Facebook is doing to kill fake accounts. It turns out that Facebook is hunting down accounts and users on an individual basis, rather than en masse via some sort of algorithm. And they're targeting the obvious villains first.

Privacy Schmrivacy: Why Facebook User Data Should Be the Least of Our Concerns [OPINION]

Privacy Schmrivacy: Why Facebook User Data Should Be the Least of Our Concerns [OPINION] | digitalcuration | Scoop.it

What is a dangerous thing, though, is the ability to draw conclusions about someone based on his behavior on the Internet.

 

A self-employed friend of mine recently had his insurance rates skyrocket because of a survey he took about his lifestyle habits. They deemed him high risk and charged him more. He complained and I shrugged my shoulders: it wasn't pleasant, I told him, but it was fair for them to draw conclusions about his future costs knowing he smokes and doesn't sleep much. But later that day, I did a Google search for "natural remedy for headache" and, forty clicks later, was down a rabbit hole of searches that had me convinced I've got pancreatic cancer. My point? What if that health insurance company got hold of my Google searches? What if they used that data to infer my habits and risk factors and future costs?

 

Of course, Facebook could sell my "likes" and re-posts to other parties. Call me naïve, but I'm not super paranoid about the conclusions made about my music preferences and habit of giving a digital thumbs up to wedding announcements and charitable causes my friends support.

My search history, however....that's a different story. Seriously: have you ever taken inventory of what you Google? Keep track for a day and tell me what conclusions you'd draw about yourself given that data.

Facebook Could Now Advertise To Children, Thanks To Updated Federal Privacy Rules

Facebook Could Now Advertise To Children, Thanks To Updated Federal Privacy Rules | digitalcuration | Scoop.it

New advertising rules may have lifted a major barrier to Facebook’s long-held desire of signing up children under 13 years of age. The Federal Trade Communication revised the Children’s Online Privacy Protection Act (COPPA) to exclude parental consent from ads that are based on behavior, rather than personal information. So-called “contextual advertisements” would permit Facebook to monetize children’s activity without violating rules about collecting their private information. Alan Simpson, Vice President of children’s online advocacy network, Common Sense media, tells us that though they agree with some of the rule changes, with regard to contextual ads, “Common Sense doesn’t like this part, and the industry lobbyists probably do.”

Facebook propose de payer pour rendre un courriel plus visible

Facebook propose de payer pour rendre un courriel plus visible | digitalcuration | Scoop.it

Facebook, toujours à la recherche de nouvelles sources de revenus, a annoncé jeudi le lancement d'un test visant à faire payer lors de l'envoi de certains messages par son intermédiaire, afin qu'ils aient plus de chances d'attirer l'attention de leur destinataire.

 

«Le test donnera à un petit nombre de personnes l'option de payer pour avoir un message dirigé vers la boîte de réception plutôt que le dossier "autres" d'un destinataire qu'ils n'ont pas parmi leurs contacts», ajoute-t-il

 

«Nous commençons à tester avec 1 dollar par message, et nous continuerons à tester pour trouver le prix optimal», a précisé une porte-parole de Facebook à l'AFP.

 

Le test concernera dans un premier temps des individus basés aux États-Unis, et le nombre de messages redirigés du dossier «autres» à la boîte de réception sera limité à un par semaine.

How spyware on rental PCs captured users' most intimate moments

How spyware on rental PCs captured users' most intimate moments | digitalcuration | Scoop.it

On the second-to-last Monday of 2010, Brian Byrd was playing video poker on his Dell Inspiron laptop when someone knocked on the door of his home in Casper, Wyoming. The visitor, who drove a truck from the local Aaron's rent-to-own store that furnished the PC five months earlier, said the 25-year-old Byrd was behind in his payments and demanded he pay up at once. He then brandished a picture that was about to cause a national privacy uproar.

 

The image showed Byrd on his home couch using the very laptop in question to play online poker. The employee was also privy to a screenshot of the website Byrd's PC was displaying the moment the photo was surreptitiously taken, along with keystrokes he was entering while visiting a website. When Byrd demanded an explanation, the employee, identified in a police report as 24-year-old Christopher Mendoza, said he wasn't supposed to answer. But he went on to disclose that the PC contained software that allowed Aaron's employees to track its physical location and remotely activate its webcam and capture screenshots and keystrokes. Mendoza, according to court records, left the premises after Byrd produced a copy of a receipt showing the laptop had been paid for in full on October 1.

Foursquare Starts Using Facebook’s Data For Recommendations As Rivalry Between The Two Heats Up

Foursquare Starts Using Facebook’s Data For Recommendations As Rivalry Between The Two Heats Up | digitalcuration | Scoop.it

As competition between the two ramps up, Foursquare has announced that it will expand recommendations to include suggestions made by users’ Facebook friends who have also signed up for the location-based discovery service. The move means that if you have connected your Facebook and Foursquare accounts, your Facebook contacts’ public activity on Foursquare will influence the recommendations you see in Explore, even if you aren’t connected to them on the app.

Foursquare says that this will allow it to provide “better personalized insights.” It made sure to add, however, that check-ins will still only be shared with your friends who are also on the app and will not be posted to Facebook without permission.

"Pincer pour zoomer" : le brevet d'Apple invalidé par la justice américaine

"Pincer pour zoomer" : le brevet d'Apple invalidé par la justice américaine | digitalcuration | Scoop.it

Un brevet d'Apple, portant sur une fonction des écrans tactiles permettant d'agrandir ou réduire une image en faisant un geste de pincement avec deux doigts, a été invalidé, selon un document transmis à la justice par Samsung. Le brevet est l'un de ceux sur la base desquels un jury de Californie avait estimé, au mois d'août, que Samsung devait payer une amende de 1,05 milliard de dollars (840 millions d'euros) pour avoir copié certains éléments de l'iPhone et de l'iPad. Le verdict définitif de ce nouveau procès doit néanmoins encore être rendu par la juge.

 

Samsung, qui espère toujours faire annuler sa condamnation ou au moins réduire son amende, lui a transmis mercredi 19 décembre une copie d'une décision préliminaire de l'Office américain des brevets. Ce dernier y estime, dans le cadre d'un réexamen, que le geste de "pincer pour zoomer" n'était pas assez original pour valoir un brevet à Apple. C'est la deuxième fois que le groupe américain utilise un brevet lors du procès californien dont Samsung signale l'invalidation à la justice.

Google, Apple et Facebook pourront exploiter les brevets Kodak

Google, Apple et Facebook pourront exploiter les brevets Kodak | digitalcuration | Scoop.it
Après cinq mois de négociations, Kodak a réussi à vendre son portefeuille de 1100 brevets.

 

Pas de jaloux, tous les candidats au rachat des brevets Kodak pourront les exploiter. Le géant déchu de la photographie Eastman Kodak a annoncé mercredi avoir trouvé des acheteurs pour un portefeuille d'un millier de brevets qu'il essayait de vendre depuis des mois, et dont il va finalement tirer 525 millions de dollars.

 

Les géants high-tech bénéficieront de droits de licence

Le portefeuille va revenir à un consortium dont le groupe en faillite n'identifie dans son communiqué que les deux chefs de file, les sociétés spécialisées dans la gestion de brevets RPX Corporation et Intellectual Ventures. Mais un document transmis séparément à la justice liste une série d'acteurs importants du secteur technologique auxquels les deux sociétés vont accorder des licences sur les brevets en échange d'une partie de la somme promise à Kodak.

Le document cite les groupes Apple et Microsoft, Google, Facebook, Amazon, le fabricant canadien du blackberry RIM, les groupes électroniques sud-coréen Samsung et taiwanais HTC, l'équipementier en télécoms chinois Huawei, le groupe japonais de technologies de l'image Fujifilm ou le service d'édition de photos en ligne Shutterfly.

How We Used Facebook to Power Our Investigation Into Patient Harm

How We Used Facebook to Power Our Investigation Into Patient Harm | digitalcuration | Scoop.it

A typical investigation might proceed like this: a journalist spends months (or more) reporting, keeps it fairly hush-hush, writes several stories, and then monitors comments and the social web as reaction unfolds.

But for our ongoing investigation into patient safety, spearheaded by reporters Marshall Allen and Olga Pierce, we’ve launched community and crowdsourcing efforts long before we’ve published a single traditional story. We’ve developed a database of sources that is helping to inform the investigation as we report it. And we are using Facebook to create a space for patients, providers and journalists to discuss patient safety issues openly.

Social Number is a social network for people who want to remain anonymous | digitalcuration | Scoop.it
ocial networks are often trying to get you to share more. Social Number is a new social network that wants you to share as little as possible.

On Social Number, which launched in beta yesterday, people identify themselves by a number rather than username. This number keeps them anonymous so that they can speak more freely without fear of over-sharing.

“We feel that right now there is no privacy on any social networks. People get fired for saying the wrong things. Governments come after you for just expressing your thoughts,” said Social Network's chief executive, would only identify himself by the initials M.K.

Irish Newspaper Collective Wants to Charge License Fees for Links

Irish Newspaper Collective Wants to Charge License Fees for Links | digitalcuration | Scoop.it

Don’t hurt yourself trying to understand their reasoning; it’s utter nonsense. First and foremost, let’s consider the business aspect. There’s the fact that naming a work’s title does not and cannot be copyright infringement – not under US law (I’m not familiar with Irish copyright law). A link (or the URL inside it) is little more than a name, so arguably the same rule would apply. And even if it is more than a name, the URL can be regarded as a factual statement (you can find the content here) and facts arguably cannot be copyrighted in the US (some courts disagree).

The 20 Biggest Brand Fails of 2012 | digitalcuration | Scoop.it

Judging by the traffic trends on this blog, it seems the only thing more enjoyable than a brilliant, uplifting, inspirational marketing success is a horrible, embarrassing, cringe-worthy marketing blunder—otherwise known as the big brand fail. Every year there's plenty of them—the accidental tweet, the offensive billboard, the Photoshop disaster, the just-plain-tasteless ad. At the link below, we've compiled 20 of the most notable brand fails from 2012—a nice dose of ad-enfreude to fill your evil rubbernecking hearts with joy. Just be glad it wasn't you. And try to learn a lesson from the Harvey Nichols model above and refrain from pissing yourself with laughter. It's not a good look.

Facebook updates cover photo and News Feed ad policy, limits text to 20% of image

Facebook updates cover photo and News Feed ad policy, limits text to 20% of image | digitalcuration | Scoop.it

Facebook is changing its policy regarding text overlay on photos in pages’ cover photos and News Feed ads to limit text to no more than 20 percent of an image’s area.

Previously, Facebook restricted the use of ”calls to action” and “price and purchase information” in photos because it wanted to prevent advertisers from sharing images that looked like traditional banner ads. The policy was vague and not always followed or enforced. The new policy set to go into effect Jan. 15 is much clearer, and Facebook has told partners that it is preparing tools to help advertisers be compliant.

 

Ad Guidelines Section III.D now says:

“Ads and sponsored stories for News Feed that originate from Pages may not include images with more than 20% text.”

News Feed ads may now use calls to action or purchase information in photos as long as the text makes up less than 20 percent of the image. Cover photos still have restrictions on the type of text that can be used.

Pages Terms Section III.B reads:

Covers may not include:

i.    images with more than 20% text;ii.    price or purchase information, such as “40% off” or “Download it on socialmusic.com”;iii.    contact information such as a website address, email, mailing address, or information that should go in your Page’s “About” section;iv.    references to Facebook features or actions, such as “Like” or “Share” or an arrow pointing from the cover photo to any of these features; or
v.    calls to action, such as “Get it now” or “Tell your friends.”

Faking IT: 5 executives who lied on their resumes | digitalcuration | Scoop.it

Poor Scott Thompson. Just when his plan of revamping Yahoo was gaining steam, the falsified resume (or "Resume-Gate" as it shall forever be known) cut short his stint as CEO. In spite of the "lie" being of an inconsequential nature -- Thompson's resume claimed he had a degree in Computer Science when he didn't - Thompson will now have to add "ex-CEO, Yahoo" on his resume.

 

However, Thompson isn't the first executive from an IT company to be forced out due to false information on the resume. The ignominious list contains other CEOs, CFOs and even the IT Head of the US Department of Homeland Security.

Facebook real name row in Germany

Facebook real name row in Germany | digitalcuration | Scoop.it
Facebook has been ordered to stop making people use their real names on the social network by a German data protection body.

The policy violates German laws that give people the right to use pseudonyms online, said the data protection agency in Schleswig-Holstein.

The agency has issued a decree demanding that Facebook let people use fake names immediately.

Facebook said it would fight the decree "vigorously" and that its naming policy met European data protection rules.

"It is unacceptable that a US portal like Facebook violates German data protection law unopposed and with no prospect of an end," said Thilo Weichert, head of the regional data protection office in Schleswig Holstein, in a statement.

The ability to use a pseudonym on Facebook was "reasonable" said Mr Weichert and would allow people to use the service "without fear of unpleasant consequences".

Under most existing laws, if our findings were extrapolated nationally, several million teens could be prosecuted for child pornography,” explains a new study on teen sexting, which finds that a whopping 28% of teenagers text fully-nude pictures of themselves. We took a deep dive into the much reported Pediatrics & Adolescent Medicine article, and found some weird insights into a 21st century trend that is quickly becoming the norm among teenagers.

White kids love sexting. More than any other demographic (Hispanic, African American, and Asian), white students reported sexting in the highest percentage (35%), nearly double that of Asians (19). African Americans were a somewhat distant second at 27%, followed by Hispanics (21%), and Asians.

VIDEO - Cuisinella : le dér@page incontrôlé et les excuses de la marque | digitalcuration | Scoop.it
Ce spécialiste des cuisines a publié une vidéo, très mal accueillie sur le Net, et patine depuis.

Dans un monde envahi par la publicité, il est devenu difficile pour une entreprise de sortir du lot. Certes, il reste Internet et ses logiques virales mais encore faut-il savoir manier l'outil avec tact. Et visiblement, ce n’est pas le cas de Cuisinella, filiale du groupe SALM : à peine mise en ligne mardi, sa dernière vidéo est devenue la risée du Web puis a été retirée dans la foulée. En vain.

"N’attendez pas qu’il soit trop tard pour en profiter". C’est autour de ce slogan que Cuisinella a élaboré une vidéo destinée au Web et qui s’inspire des canulars en caméra cachée. Sauf que mettre l’acheteur dans la peau d’un mort victime d’un sniper pour l’inciter à consommer, c’est tout sauf incitatif. Surtout lorsque le second degré n’est pas maîtrisé.

"Bad buzz" : Cuisinella s’explique et s’excuse: "Bien conscient que l’effet recherché n’a pas été atteint, Cuisinella admet qu’il "ne souhaitait pas choquer à ce point. Sa direction dont la Présidente Anne Leitzgen font amende honorable et s’en s'excusent sincèrement si cela a pu être le cas. Aussi, la marque a décidé de ne plus communiquer sur cette vidéo afin de ne pas encourager sa propagation."
