ICT Security-Sécurité PC et Internet

Les messages vous indiquant que votre ordinateur est infecté et qu’il faut d’urgence appeler un numéro de téléphone ou télécharger un logiciel de sécurité sont pour la plupart des fausses alertes. Il s’agit de vendre des logiciels inutiles, ou pire de dérober des données personnelles.

Über das Unternehmen Geofeedia konnten US-Behörden Standortdaten von Facebook- und Twitter-Nutzern sammeln.
Facebook, Instagram und Twitter kennen viele Details ihrer Nutzer. Dies hat offenbar auch die US-Regierung erkannt und die Datenströme der Dienste über die Analytics-Plattform Geofeedia angezapft . Laut der Bürgerrechtsorganisation American Civil Liberties Union (ACLU) nutzte unter anderem die Polizei diese Informationen, um die Rassenproteste in Oakland und Baltimore zu überwachen.

Die Sammlung der Daten wurde von dem in Chicago ansässigen Unternehmen Geofeedia übernommen, das die Informationen dann an rund 500 Strafverfolgungs- und Sicherheitsbehörden weitergereicht haben soll. Neben persönlichen Informationen wurden auch Standortdaten von Nutzern gesammelt.

Facebook und Twitter beteuern, dass es sich bei dem abgegriffenen Daten um öffentlich zugängliche Informationen handeln würde. Als Reaktion auf die Vorwürfe schränkten beide Unternehmen den Zugriff von Geofeedia auf die Datenströme der sozialen Netzwerke ein oder sperrten den Anbieter sogar.

Yes, hackers did manage to steal millions of account credentials back in 2012.
Make sure you have protected your account, and enabled two-step verification.

At the time, security commentators such as Brian Krebs, Troy Hunt and myselfurged internet users to be wary of the claims - as they had not been verified.

After all, it seemed possible that the data had been collected from heavily-reported mega breaches at Tumblr, LinkedIn and MySpace.

Now, however, Dropbox has confirmed to the media that a 5GB archive of files, containing the email addresses and hashed passwords for some 68,680,741 accounts, is genuine.

Who Will Own Your Data If the Tech Bubble Bursts?
Corporations, data brokers, and even criminals might buy failed companies just for their users’ personal information.

Desperate companies will resort, if they can, to selling the detailed data they’ve meticulously collected about their users—whether it’s personally identifiable information, data about preferences, habits, and hobbies, or national-security files. That data, formerly walled-off and spoon-fed only to paying advertisers, would be attractive to both licit and criminal buyers. Easily searchable datasets could generate new innovations and  investments—but it would be difficult to know who’s buying up sensitive datasets, and why.

If contracts and privacy policies prevent a floundering company from selling user data, there’s still another way to profit. Most privacy policies that promise not to sell user data include a caveat in case of bankruptcy or sale. In fact, a New York Times analysis of the top 100 websites in the U.S. last year found that 85 of them include clauses in their privacy policies like this one from Facebook:

If the ownership or control of all or part of our Services or their assets changes, we may transfer your information to the new owner.

Web users face an even greater threat to their privacy as large ISPs align themselves more closely with data brokers to track their customers, an advocacy group said.

Several large ISPs have either formed partnerships with, or acquired, data tracking and analytics firms in recent years, giving them a "vast storehouse of consumer data," according to a report Wednesday from the Center for Digital Democracy.

"ISPs have been on a shopping spree to help build their data-targeting system across devices and platforms," the report says. "Superfast computers analyze our information ... to decide in milliseconds whether to target us for marketing and more."

Through digital dossiers that merge all of this information, we can be bought and sold in an instant -- to financial marketers, fast-food companies, and health advertisers -- all without our knowledge."

ISPs are increasingly using programmatic advertising "fueled by powerful alliances among data, media, advertising and technology companies," the report says. The new advertising model "encompasses nearly all the device and formats we rely on -- including mobile, audio and video."

Some ISPs now have the ability to marry a customer's Web surfing history with his or her TV viewing habits and mobile app use to target advertising across devices, the report says.

Die Ransom-Ware informiert ihre Opfer über eine Sprachnachricht über die Forderungen. Die Erpresser wollen demnächst auch lokalisierte Versionen der Sprachnachricht anbieten.

Es soll die erste Ransomware sein, die bei den Opfern über eine Sprachdatei Lösegeldforderung stellt. Bisher ist es üblich, dass in solchen Fällen ein Bild eingeblendet wird. Wie die Sicherheitsexperten von Trend Micro mitteilen, soll die Erpressersoftware Cerber “Ransom_Cerber.A” dazu auch noch eine Audiodatei abspielen. Darin informieren die Erpresser die Nutzer darüber, dass alle “Dokumente, Fotos, Datenbanken und andere wichtige Dateien” verschlüsselt wurden.

It's all gone. All the passwords, all the user names, all the credit card numbers, the selfies, the fingerprints, the emails.

The state of tech security is currently so dire that it feels like anything you have ever stored on a computer, or a company or government has ever stored about you, has already been hacked into by somebody.

It's become so bad that it's already generated a mirthless cliché -- that there are only two types of companies: the ones that have been hacked and the ones that don't yet know they've been hacked.

So what can we do? I'd suggest three decent starting points.

First, as consumers we need to stop shrugging and accepting data leaks as business as usual. Security should influence our buying decisions: the organisations we deal with won't take security seriously unless customers and the public do, too. Our behaviour should signal to companies that good security can be a competitive differentiator. At the moment our apathy too often lets them off the hook. We as consumers need to understand the value of our data and then hold those that store it to account.

Second, companies should design security as a fundamental part of the services we use, not a nice-to-have addition. Few hackers will give a new service time to implement security before attacking it, yet too many innovations (the IoT, I'm looking at you) seem to think security is a secondary consideration until they make it big. Until that changes, security will always be an afterthought.

Third, the use of strong encryption should be the standard, not the exception. The digital services we use are now too intimate, too important, to be left unencrypted. The revelations of the last few years have shown us that no stream of data on the internet will go untapped by crooks or government.

„Friss, oder stirb“ – nach diesem Motto ist die Datenschutzrichtlinie gestaltet. Entweder Sie lassen es sich gefallen, dass Ihre Daten wichtiger als deren Schutz sind, oder Sie spielen das Spiel nicht. Haben Sie sich bereits angemeldet, haben Sie Pech, denn Ihre Daten werden munter weiterverwendet – irgendwo auf diesem Planeten.

Folgen der Kritiken zum Datenschutz

Während viele mit dem Smartphone vor Augen vor lauter Pokémon den Datenschutz nicht mehr zu sehen scheinen, haben andere bereits aufgeschrien. Der von Niantic als „Versehen“ bezeichnete Rundum-Zugriff aufs Google-Account soll mit der Version 1.02 der Vergangenheit angehören. Nun könnte man womöglich neue Datenschutzstandards erwarten, die Daten auch wirklich schützen. Stattdessen setzt Niantic lieber auf Safe Harbor. Dass der Europäische Gerichtshof eben dieses Programm aufgrund mangelndem Schutz für private Daten voriges Jahr kippte, scheint unwesentlich zu sein.

Or, relève Adam Reeve, dans le second cas « Pokémon Go » peut quasiment tout faire  :

Lire vos e-mails.
Vous en envoyer.
Accéder à votre Google Drive (qui permet de stocker des fichiers – que « Pokémon Go » peut supprimer  !).
Lire vos historiques de recherche sur Google et Google Maps.
Et regarder vos photos.

Always with his finger on the pulse, Senator Al Franken today sent an official request to Niantic asking about particulars of the Pokémon Go privacy...

Ever felt like you were being watched online? You know, like when you read something about New York, and the next site you visit shows you ads for New York hotels? As it turns out, on my computer, there were more than 130 companies tracking my every move (check yours here, then install this plug-in).

These companies are basically engaging in mass surveillance. Just as governments justify tracking us to prevent terrorist attacks, these companies are tracking us online, without our consent, because a marginal 0.7 percent of the population clicks on their ads.

And it’s not just online advertisers. From e-commerce websites to physical retail stores, everyone is now racing to capture more data about us. Don’t be surprised if your insurance company starts charging you more because of how it thinks you should live your life!

Don’t get me wrong, I use Facebook, Google and all those other services. I use them because I find them useful, fun or because I don’t have an alternative. But I do it knowing very well that I am partly giving away my right to privacy.
