We all know that our cell phones constantly give our location away to our mobile network operators; that’s how they work. A group of researchers has figured out a way to fix that. “Pretty Good Phone Privacy” (PGPP) protects both user identity and user location using the existing cellular networks. It protects users from fake cell phone towers (IMSI-catchers) and surveillance by cell providers.

It’s a clever system. The players are the user, a traditional mobile network operator (MNO) like AT&T or Verizon, and a new mobile virtual network operator (MVNO). MVNOs aren’t new. They’re intermediaries like Cricket and Boost.

Here’s how it works:

1. One-time setup: The user’s phone gets a new SIM from the MVNO. All MVNO SIMs are identical.
2. Monthly: The user pays their bill to the MVNO (credit card or otherwise) and the phone gets anonymous authentication (using Chaum blind signatures) tokens for each time slice (e.g., hour) in the coming month.
3. Ongoing: When the phone talks to a tower (run by the MNO), it sends a token for the current time slice. This is relayed to a MVNO backend server, which checks the Chaum blind signature of the token. If it’s valid, the MVNO tells the MNO that the user is authenticated, and the user receives a temporary random ID and an IP address. (Again, this is now MVNOs like Boost already work.)
4. On demand: The user uses the phone normally.

The MNO doesn’t have to modify its system in any way. The PGPP MVNO implementation is in software. The user’s traffic is sent to the MVNO gateway and then out onto the Internet, potentially even using a VPN.

All connectivity is data connectivity in cell networks today. The user can choose to be data-only (e.g., use Signal for voice), or use the MVNO or a third party for VoIP service that will look just like normal telephony.

The group prototyped and tested everything with real phones in the lab. Their approach adds essentially zero latency, and doesn’t introduce any new bottlenecks, so it doesn’t have performance/scalability problems like most anonymity networks. The service could handle tens of millions of users on a single server, because it only has to do infrequent authentication, though for resilience you’d probably run more.

The paper is here.

Apple only lets you access iPhone apps through its own App Store, which it says keeps everything safe. It appeared to bolster that idea when it announced in 2020 that it would ask app makers to fill out what are essentially privacy nutrition labels. Just like packaged food has to disclose how much sugar it contains, apps would have to disclose in clear terms how they gobble your data. The labels appear in boxes toward the bottom of app listings. (Click here for my guide on how to read privacy nutrition labels.)

But after I studied the labels, the App Store is now a product I trust less to protect us. In some ways, Apple uses a narrow definition of privacy that benefits Apple — which has its own profit motivations — more than it benefits us.

Apple’s big privacy product is built on a shaky foundation: the honor system. In tiny print on the detail page of each app label, Apple says, “This information has not been verified by Apple.”

The first time I read that, I did a double take. Apple, which says caring for our privacy is a “core responsibility,” surely knows devil-may-care data harvesters can’t be counted on to act honorably. Apple, which made an estimated $64 billion off its App Store last year, shares in the responsibility for what it publishes.

It’s true that just by asking apps to highlight data practices, Apple goes beyond Google’s rival Play Store for Android phones. It has also promised to soon make apps seek permission to track us, which Facebook has called an abuse of Apple’s monopoly over the App Store.

In an email, Apple spokeswoman Katie Clark-AlSadder said: “Apple conducts routine and ongoing audits of the information provided and we work with developers to correct any inaccuracies. Apps that fail to disclose privacy information accurately may have future app updates rejected, or in some cases, be removed from the App Store entirely if they don’t come into compliance.”

My spot checks suggest Apple isn’t being very effective.

And even when they are filled out correctly, what are Apple’s privacy labels allowing apps to get away with not telling us?

Trust but verify

A tip from a tech-savvy Washington Post reader helped me realize something smelled fishy. He was using a journaling app that claimed not to collect any data but, using some technical tools, he spotted it talking an awful lot to Google.

[…]

To be clear, I don’t know exactly how widespread the falsehoods are on Apple’s privacy labels. My sample wasn’t necessarily representative: There are about 2 million apps, and some big companies, like Google, have yet to even post labels. (They’re only required to do so with new updates.) About 1 in 3 of the apps I checked that claimed they took no data appeared to be inaccurate. “Apple is the only one in a position to do this on all the apps,” says Jackson.

But if a journalist and a talented geek could find so many problems just by kicking over a few stones, why isn’t Apple?

Even after I sent it a list of dubious apps, Apple wouldn’t answer my specific questions, including: How many bad apps has it caught? If being inaccurate means you get the boot, why are some of the ones I flagged still available?

[…]

We need help to fend off the surveillance economy. Apple’s App Store isn’t doing enough, but we also have no alternative. Apple insists on having a monopoly in running app stores for iPhones and iPads. In testimony to Congress about antitrust concerns last summer, Apple CEO Tim Cook argued that Apple alone can protect our security.

Other industries that make products that could harm consumers don’t necessarily get to write the rules for themselves. The Food and Drug Administration sets the standards for nutrition labels. We can debate whether it’s good at enforcement, but at least when everyone has to work with the same labels, consumers can get smart about reading them — and companies face the penalty of law if they don’t tell the truth.

Apple’s privacy labels are not only an unsatisfying product. They should also send a message to lawmakers weighing whether the tech industry can be trusted to protect our privacy on its own.

Instagram is adding a new “Recently deleted” folder to the app’s menu that temporarily stores posts after you remove them from your profile or archive, giving you the ability to restore deleted posts if you change your mind.

The folder includes sections for photos, IGTV, Reels, and Stories posts. No one else can see your recently deleted posts, but as long as a photo or video is still in the folder, it can be restored. Regular photos, IGTV videos, and Reels remain in the folder for up to 30 days, after which they’re gone forever. Stories stick around for up to 24 hours before they’re permanently removed, but you can still access them in your Stories archive.

Not content to only wield its creepy surveillance infrastructure against warehouse workers and employees considering unionization, Amazon is reportedly gearing up to install perpetually-on cameras inside its fleet of delivery vehicles as well.

A new report from The Information claims that Amazon recently shared the plans in an instructional video sent out to the contractor workers who drive the Amazon-branded delivery vans.

In the video, the company reportedly explains to drivers that the high-tech video cameras will use artificial intelligence to determine when drivers are engaging in risky behavior, and will give out verbal warnings including “Distracted driving,” “No stop detected” and “Please slow down.”

According to a video posted to Vimeo a week ago, the hardware and software for the cameras will be provided through a partnership with California-based company Netradyne, which is also responsible for a platform called Driveri that similarly uses artificial intelligence to analyze a driver’s behavior as they operate a vehicle.

While the camera’s automated feedback will be immediate, other data will also reportedly be stored for later analysis that will help the company to evaluate its fleet of drivers.

Although it’s not clear when Amazon plans to install the cameras or how many of the vehicles in the company’s massive fleet will be outfitted with them, the company told The Information in a statement that the software will be implemented in the spirit of increasing safety precautions and not, you know, bolstering an insidious and growing surveillance apparatus.

Encrypted service providers are urging lawmakers to back away from a controversial plan that critics say would undercut effective data protection measures.

ProtonMail, Threema, Tresorit and Tutanota — all European companies that offer some form of encrypted services — issued a joint statement this week declaring that a resolution the European Council adopted on Dec. 14 is ill-advised. That measure calls for “security through encryption and security despite encryption,” which technologists have interpreted as a threat to end-to-end encryption. In recent months governments around the world, including the U.S., U.K., Australia, New Zealand, Canada, India and Japan, have been reigniting conversations about law enforcement officials’ interest in bypassing encryption, as they have sporadically done for years.

In a letter that will be sent to council members on Thursday, the authors write that the council’s stated goal of endorsing encryption, and the council’s argument that law enforcement authorities must rely on accessing electronic evidence “despite encryption,” contradict one another. The advancement of legislation that forces technology companies to guarantee police investigators a way to intercept user messages, for instance, repeatedly has been scrutinized by technology leaders who argue there is no way to stop such a tool from being abused.

The resolution “will threaten the basic rights of millions of Europeans and undermine a global shift towards adopting end-to-end encryption,” say the companies, which offer users either encrypted email, file-sharing or messaging.

“[E]ncryption is an absolute, data is either encrypted or it isn’t, users have privacy or they don’t,” the letter, which was shared with CyberScoop in advance, states. “The desire to give law enforcement more tools to fight crime is obviously understandable. But the proposals are the digital equivalent of giving law enforcement a key to every citizens’ home and might begin a slippery slope towards greater violations of personal privacy.”

The Indian government has sent a fierce letter to Facebook over its decision to update the privacy rules around its WhatsApp chat service, and asked the antisocial media giant to put a halt to the plans.In an email from the IT ministry to WhatsApp head Will Cathcart, provided to media outlets, the Indian government notes that the proposed changes “raise grave concerns regarding the implications for the choice and autonomy of Indian citizens.”In particular, the ministry is incensed that European users will be given a choice to opt out over sharing WhatsApp data with the larger Facebook empire, as well as businesses using the platform to communicate with customers, while Indian users will not.“This differential and discriminatory treatment of Indian and European users is attracting serious criticism and betrays a lack of respect for the rights and interest of Indian citizens who form a substantial portion of WhatsApp’s user base,” the letter says. It concludes by asking WhatsApp to “withdraw the proposed changes.”IndiaIndia’s top techies form digital foundation to fight Apple and GoogleREAD MOREThe reason that Europe is being treated as a special case by Facebook is, of course, the existence of the GDPR privacy rules that Facebook has repeatedly flouted and as a result faces pan-European legal action.

WhatsApp said on Friday that it won’t enforce the planned update to its data-sharing policy until May 15, weeks after news about the new terms created confusion among its users, exposed the Facebook app to a potential lawsuit, triggered a nationwide investigation and drove tens of millions of its loyal fans to explore alternative messaging apps.

“We’re now moving back the date on which people will be asked to review and accept the terms. No one will have their account suspended or deleted on February 8. We’re also going to do a lot more to clear up the misinformation around how privacy and security works on WhatsApp. We’ll then go to people gradually to review the policy at their own pace before new business options are available on May 15,” the firm said in a blog post.

I’m pretty sure there is no confusion. People just don’t want all their data shared to Facebook when they were promised it wouldn’t be. So they are leaving to Signal and Telegram.

WhatsApp updated its privacy policy at the turn of the new year. Users were notified via a popup message upon opening the app that their data would now be shared with Facebook and other companies come February 8. Due to Facebook’s notorious history with user data and privacy, the new update has since then garnered criticism with many people migrating to alternative messaging apps like Signal and Telegram. Microsoft entered the playing field too, recommending users to use Skype in place of the Facebook-owned WhatsApp.

In the latest, Turkey has now launched an antitrust probe into Facebook and WhatsApp regarding the updated privacy policy. Bloomberg reports that:

Turkey’s antitrust board launched an investigation into Facebook Inc. and its messaging service WhatsApp Inc. over new usage terms that have sparked privacy concerns.

[…]

The regulator also said it was halting implementation of such terms, it said on Monday. The new terms would result in “more data being collected, processed and used by Facebook,” according to the statement.

In the wake of the violent insurrection at the U.S. Capitol by scores of President Trump’s supporters, a lone researcher began an effort to catalogue the posts of social media users across Parler, a platform founded to provide conservative users a safe haven for uninhibited “free speech” — but which ultimately devolved into a hotbed of far-right conspiracy theories, unchecked racism, and death threats aimed at prominent politicians.

The researcher, who asked to be referred to by her Twitter handle, @donk_enby, began with the goal of archiving every post from January 6, the day of the Capitol riot; what she called a bevy of “very incriminating” evidence. According to the Atlantic Council’s Digital Forensic Research Lab, among other sources, Parler is one of a several apps used by the insurrections to coordinate their breach of the Capitol, in a plan to overturn the 2020 election results and keep Donald Trump in power.

Five people died in the attempt.

Hoping to create a lasting public record for future researchers to sift through, @donk_enby began by archiving the posts from that day. The scope of the project quickly broadened, however, as it became increasingly clear that Parler was on borrowed time. Apple and Google announced that Parler would be removed from their app stores because it had failed to properly moderate posts that encouraged violence and crime. The final nail in the coffin came Saturday when Amazon announced it was pulling Parler’s plug.

In an email first obtained by BuzzFeed News, Amazon officials told the company they planned to boot it from its clouding hosting service, Amazon Web Services, saying it had witnessed a “steady increase” in violent content across the platform. “It’s clear that Parler does not have an effective process to comply with the AWS terms of service,” the email read.

Operating on little sleep, @donk_enby began the work of archiving all of Parler’s posts, ultimately capturing around 99.9 percent of its content. In a tweet early Sunday, @donk_enby said she was crawling some 1.1 million Parler video URLs. “These are the original, unprocessed, raw files as uploaded to Parler with all associated metadata,” she said. Included in this data tranche, now more than 56 terabytes in size, @donk_enby confirmed that the raw video files include GPS metadata pointing to exact locations of where the videos were taken.

@donk_enby later shared a screenshot showing the GPS position of a particular video, with coordinates in latitude and longitude.

The privacy implications are obvious, but the copious data may also serve as a fertile hunting ground for law enforcement. Federal and local authorities have arrested dozens of suspects in recent days accused of taking part in the Capitol riot, where a Capitol police officer, Brian Sicknick, was fatally wounded after being struck in the head with a fire extinguisher.

[…]

Kirtaner, creator of 420chan — a.k.a. Aubrey Cottle — reported obtaining 6.3 GB of Parler user data from an unsecured AWS server in November. The leak reportedly contained passwords, photos and email addresses from several other companies as well. Parler CEO John Matze later claimed to Business Insider that the data contained only “public information” about users, which had been improperly stored by an email vendor whose contract was subsequently terminated over the leak. (This leak is separate from the debunked claim that Parler was “hacked” in late November, proof of which was determined to be fake.)

In December, Twitter suspended Kirtaner for tweeting, “I’m killing Parler and its fucking glorious,” citing its rules against threatening “violence against an individual or group of people.” Kirtaner’s account remains suspended despite an online campaign urging Twitter’s safety team to reverse its decision. Gregg Housh, an internet activist involved in many early Anonymous campaigns, noted online that the tweet was “not aimed at a person and [was] not actually violent.”

Engineers at Cloudflare and Apple say they’ve developed a new internet protocol that will shore up one of the biggest holes in internet privacy that many don’t know even exists. Dubbed Oblivious DNS-over-HTTPS, or ODoH for short, the new protocol makes it far more difficult for internet providers to know which websites you visit.

But first, a little bit about how the internet works.

Every time you go to visit a website, your browser uses a DNS resolver to convert web addresses to machine-readable IP addresses to locate where a web page is located on the internet. But this process is not encrypted, meaning that every time you load a website the DNS query is sent in the clear. That means the DNS resolver — which might be your internet provider unless you’ve changed it — knows which websites you visit. That’s not great for your privacy, especially since your internet provider can also sell your browsing history to advertisers.

Recent developments like DNS-over-HTTPS (or DoH) have added encryption to DNS queries, making it harder for attackers to hijack DNS queries and point victims to malicious websites instead of the real website you wanted to visit. But that still doesn’t stop the DNS resolvers from seeing which website you’re trying to visit.

Enter ODoH, which builds on previous work by Princeton academics. In simple terms, ODoH decouples DNS queries from the internet user, preventing the DNS resolver from knowing which sites you visit.

Here’s how it works: ODoH wraps a layer of encryption around the DNS query and passes it through a proxy server, which acts as a go-between the internet user and the website they want to visit. Because the DNS query is encrypted, the proxy can’t see what’s inside, but acts as a shield to prevent the DNS resolver from seeing who sent the query to begin with.

“What ODoH is meant to do is separate the information about who is making the query and what the query is,” said Nick Sullivan, Cloudflare’s head of research.

In other words, ODoH ensures that only the proxy knows the identity of the internet user and that the DNS resolver only knows the website being requested. Sullivan said that page loading times on ODoH are “practically indistinguishable” from DoH and shouldn’t cause any significant changes to browsing speed.

A key component of ODoH working properly is ensuring that the proxy and the DNS resolver never “collude,” in that the two are never controlled by the same entity, otherwise the “separation of knowledge is broken,” Sullivan said. That means having to rely on companies offering to run proxies.

Sullivan said a few partner organizations are already running proxies, allowing for early adopters to begin using the technology through Cloudflare’s existing 1.1.1.1 DNS resolver. But most will have to wait until ODoH is baked into browsers and operating systems before it can be used. That could take months or years, depending on how long it takes for ODoH to be certified as a standard by the Internet Engineering Task Force.

Since Facebook acquired WhatsApp in 2014, users have wondered and worried about how much data would flow between the two platforms. Many of them experienced a rude awakening this week, as a new in-app notification raises awareness about a step WhatsApp actually took to share more with Facebook back in 2016.

On Monday, WhatsApp updated its terms of use and privacy policy, primarily to expand on its practices around how WhatsApp business users can store their communications. A pop-up has been notifying users that as of February 8, the app’s privacy policy will change and they must accept the terms to keep using the app. As part of that privacy policy refresh, WhatsApp also removed a passage about opting out of sharing certain data with Facebook: “If you are an existing user, you can choose not to have your WhatsApp account information shared with Facebook to improve your Facebook ads and products experiences.”

Some media outlets and confused WhatsApp users understandably assumed that this meant WhatsApp had finally crossed a line, requiring data-sharing with no alternative. But in fact the company says that the privacy policy deletion simply reflects how WhatsApp has shared data with Facebook since 2016 for the vast majority of its now 2 billion-plus users.

When WhatsApp launched a major update to its privacy policy in August 2016, it started sharing user information and metadata with Facebook. At that time, the messaging service offered its billion existing users 30 days to opt out of at least some of the sharing. If you chose to opt out at the time, WhatsApp will continue to honor that choice. The feature is long gone from the app settings, but you can check whether you’re opted out through the “Request account info” function in Settings.

Meanwhile, the billion-plus users WhatsApp has added since 2016, along with anyone who missed that opt-out window, have had their data shared with Facebook all this time. WhatsApp emphasized to WIRED that this week’s privacy policy changes do not actually impact WhatsApp’s existing practices or behavior around sharing data with Facebook.

[…]

None of this has at any point impacted WhatsApp’s marquee feature: end-to-end encryption. Messages, photos, and other content you send and receive on WhatsApp can only be viewed on your smartphone and the devices of the people you choose to message with. WhatsApp and Facebook itself can’t access your communications.

[…]

In practice, this means that WhatsApp shares a lot of intel with Facebook, including  account information like your phone number, logs of how long and how often you use WhatsApp, information about how you interact with other users, device identifiers, and other device details like IP address, operating system, browser details, battery health information, app version, mobile network, language and time zone. Transaction and payment data, cookies, and location information are also all fair game to share with Facebook depending on the permissions you grant WhatsApp in the first place.

WhatsApp users must agree to share their personal information with Facebook if they want to continue using the messaging service from next month, according to new terms and conditions.

“As part of the Facebook Companies, WhatsApp receives information from, and shares information with, the other Facebook Companies,” its privacy policy, updated this week, stated.

“We may use the information we receive from them, and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings, including the Facebook Company Products.”

Yes, said information includes your personal information. Thus, in other words, WhatsApp users must allow their personal info to be shared with Facebook and its subsidiaries as and when decided by the tech giant. Presumably, this is to serve personalized advertising.

If you’re a user today, you have two choices: accept this new arrangement, or stop using the end-to-end encrypted chat app (and use something else, like Signal.) The changes are expected to take effect on February 8.

When WhatsApp was acquired by Facebook in 2014, it promised netizens that its instant-messaging app would not collect names, addresses, internet searches, or location data. CEO Jan Koum wrote in a blog post: “Above all else, I want to make sure you understand how deeply I value the principle of private communication. For me, this is very personal. I was born in Ukraine, and grew up in the USSR during the 1980s.

“One of my strongest memories from that time is a phrase I’d frequently hear when my mother was talking on the phone: ‘This is not a phone conversation; I’ll tell you in person.’ The fact that we couldn’t speak freely without the fear that our communications would be monitored by KGB is in part why we moved to the United States when I was a teenager.”

Two years later, however, that vow was eroded by, well, capitalism, and WhatsApp decided it would share its users’ information with Facebook though only if they consented. That ability to opt-out, however, will no longer be an option from next month. Koum left in 2018.

That means users who wish to keep using WhatsApp must be prepared to give up personal info such as their names, profile pictures, status updates, phone numbers, contacts lists, and IP addresses, as well as data about their mobile devices, such as model numbers, operating system versions, and network carrier details, to the mothership. If users engage with businesses via the app, order details such as shipping addresses and the amount of money spent can be passed to Facebook, too.

With a nearly 80 percent uptake among the country’s population, Singapore’s TraceTogether app is one of the best examples of what a successful centralized contact tracing effort can look like as countries across the world struggle to contain the coronavirus pandemic. To date, more than 4.2 million people in Singapore have download the app or obtained the wearable the government has offered to people.

In contrast to Apple’s and Google’s Exposure Notifications System — which powers the majority of COVID-19 apps out there, including ones put out by states and countries like California and Germany — Singapore’s TraceTogether app and wearable uses the country’s own internally developed BlueTrace protocol. The protocol relies on a centralized reporting structure wherein a user’s entire contact log is uploaded to a server administered by a government health authority. Outside of Singapore, only Australia has so far adopted the protocol.

In an update the government made to the platform’s privacy policy on Monday, it added a paragraph about how police can use data collected through the platform. “TraceTogether data may be used in circumstances where citizen safety and security is or has been affected,” the new paragraph states. “Authorized Police officers may invoke Criminal Procedure Code (CPC) powers to request users to upload their TraceTogether data for criminal investigations.”

Previous versions of the privacy policy made no mention of the fact police could access any data collected by the app; in fact, the website used to say, “data will only be used for COVID-19 contact tracing.” The government added the paragraph after Singapore’s opposition party asked the Minister of State for Home Affairs if police could use the data for criminal investigations. “We do not preclude the use of TraceTogether data in circumstances where citizens’ safety and security is or has been affected, and this applies to all other data as well,” said Minister Desmond Tan.

What’s happening in Singapore is an example of the exact type of potential privacy nightmare that experts warned might happen with centralized digital contact tracing efforts. Worse, a loss of trust in the privacy of data could push people further away from contact tracing efforts altogether, putting everyone at more risk.
