How much extra will you have to pay for the privilege of being spied on?

UK ISPs have warned MPs that the costs of implementing the Investigatory Powers Bill (aka the Snooper's Charter) will be much greater than the £175 million the UK government has allotted for the task, and that broadband bills will need to rise as a result. Representatives from ISPs and software companies told the House of Commons Science and Technology Committee that the legislation greatly underestimates the "sheer quantity" of data generated by Internet users these days. They also pointed out that distinguishing content from metadata is a far harder task than the government seems to assume. Matthew Hare, the chief executive of ISP Gigaclear, said with "a typical 1 gigabit connection to someone's home, over 50 terabytes of data per year [are] passing over it. If you say that a proportion of that is going to be the communications data—the record of who you communicate with, when you communicate or what you communicate—there would be the most massive and enormous amount of data that in future an access provider would be expected to keep. The indiscriminate collection of mass data across effectively every user of the Internet in this country is going to have a massive cost."

Moreover, the larger the cache of stored data, the more worthwhile it will be for criminals and state-backed actors to gain access and download that highly-revealing personal information for fraud and blackmail. John Shaw, the vice president of product management at British security firm Sophos, told the MPs: "There would be a huge amount of very sensitive personal data that could be used by bad guys.

Disaster stories involving the Internet of Things are all the rage. They feature cars (both driven and driverless), the power grid, dams, and tunnel ventilation systems. A particularly vivid and realistic one, near-future fiction published last month in New York Magazine, described a cyberattack on New York that involved hacking of cars, the water system, hospitals, elevators, and the power grid. In these stories, thousands of people die. Chaos ensues. While some of these scenarios overhype the mass destruction, the individual risks are all real. And traditional computer and network security isn’t prepared to deal with them.Classic information security is a triad: confidentiality, integrity, and availability. You’ll see it called “CIA,” which admittedly is confusing in the context of national security. But basically, the three things I can do with your data are steal it (confidentiality), modify it (integrity), or prevent you from getting it (availability).

So far, internet threats have largely been about confidentiality. These can be expensive; one survey estimated that data breaches cost an average of $3.8 million each. They can be embarrassing, as in the theft of celebrity photos from Apple’s iCloud in 2014 or the Ashley Madison breach in 2015. They can be damaging, as when the government of North Korea stole tens of thousands of internal documents from Sony or when hackers stole data about 83 million customer accounts from JPMorgan Chase, both in 2014. They can even affect national security, as in the case of the Office of Personnel Management data breach by—presumptively—China in 2015. On the Internet of Things, integrity and availability threats are much worse than confidentiality threats. It’s one thing if your smart door lock can be eavesdropped upon to know who is home. It’s another thing entirely if it can be hacked to allow a burglar to open the door—or prevent you from opening your door. A hacker who can deny you control of your car, or take over control, is much more dangerous than one who can eavesdrop on your conversations or track your car’s location. With the advent of the Internet of Things and cyber-physical systems in general, we've given the internet hands and feet: the ability to directly affect the physical world. What used to be attacks against data and information have become attacks against flesh, steel, and concrete. Today’s threats include hackers crashing airplanes by hacking into computer networks, and remotely disabling cars, either when they’re turned off and parked or while they’re speeding down the highway. We’re worried about manipulated counts from electronic voting machines, frozen water pipes through hacked thermostats, and remote murder through hacked medical devices. The possibilities are pretty literally endless. The Internet of Things will allow for attacks we can’t even imagine.

By James Bamford Last summer, cyber investigators plowing through the thousands of leaked emails from the Democratic National Committee uncovered a clue.A user named “Феликс Эдмундович” modified one of the documents using settings in the Russian language. Translated, his name was Felix Edmundovich, a pseudonym referring to Felix Edmundovich Dzerzhinsky, the chief of the Soviet Union’s first secret-police organization, the Cheka.It was one more link in the chain of evidence pointing to Russian President Vladimir Putin as the man ultimately behind the operation.During the Cold War, when Soviet intelligence was headquartered in Dzerzhinsky Square in Moscow, Putin was a KGB officer assigned to the First Chief Directorate. Its responsibilities included “active measures,” a form of political warfare that included media manipulation, propaganda and disinformation. Soviet active measures, retired KGB Major General Oleg Kalugin told Army historian Thomas Boghart, aimed to discredit the United States and “conquer world public opinion.”As the Cold War has turned into the code war, Putin recently unveiled his new, greatly enlarged spy organization: the Ministry of State Security, taking the name from Joseph Stalin’s secret service. Putin also resurrected, according to James Clapper, the U.S. director of national intelligence, some of the KGB’s old active- measures tactics. On October 7, Clapper issued a statement: “The U.S. Intelligence community is confident that the Russian government directed the recent compromises of emails from U.S. persons and institutions, including from U.S. political organizations.” Notably, however, the FBI declined to join the chorus, according to reports by the New York Times and CNBC.A week later, Vice President Joe Biden said on NBC’s Meet the Press that "we're sending a message" to Putin and "it will be at the time of our choosing, and under the circumstances that will have the greatest impact." When asked if the American public would know a message was sent, Biden replied, "Hope not." Meanwhile, the CIA was asked, according to an NBC report on October 14, “to deliver options to the White House for a wide-ranging ‘clandestine’ cyber operation designed to harass and ‘embarrass’ the Kremlin leadership.”But as both sides begin arming their cyberweapons, it is critical for the public to be confident that the evidence is really there, and to understand the potential consequences of a tit-for-tat cyberwar escalating into a real war. 

This is a prospect that has long worried Richard Clarke, the former White House cyber czar under President George W. Bush. “It’s highly likely that any war that began as a cyberwar,” Clarke told me last year, “would ultimately end up being a conventional war, where the United States was engaged with bombers and missiles.”The problem with attempting to draw a straight line from the Kremlin to the Clinton campaign is the number of variables that get in the way. For one, there is little doubt about Russian cyber fingerprints in various U.S. campaign activities. Moscow, like Washington, has long spied on such matters. The United States, for example, inserted malware in the recent Mexican election campaign. The question isn’t whether Russia spied on the U.S. presidential election, it’s whether it released the election emails.Then there’s the role of Guccifer 2.0, the person or persons supplying WikiLeaks and other organizations with many of the pilfered emails. Is this a Russian agent? A free agent? A cybercriminal? A combination, or some other entity? No one knows.There is also the problem of groupthink that led to the war in Iraq. For example, just as the National Security Agency, the Central Intelligence Agency and the rest of the intelligence establishment are convinced Putin is behind the attacks, they also believed it was a slam-dunk that Saddam Hussein had a trove of weapons of mass destruction. Consider as well the speed of the political-hacking investigation, followed by a lack of skepticism, culminating in a rush to judgment. After the Democratic committee discovered the potential hack last spring, it called in the cybersecurity firm CrowdStrike in May to analyze the problem.

CrowdStrike took just a month or so before it conclusively determined that Russia’s FSB, the successor to the KGB, and the Russian military intelligence organization, GRU, were behind it. Most of the other major cybersecurity firms quickly fell in line and agreed. By October, the intelligence community made it unanimous. That speed and certainty contrasts sharply with a previous suspected Russian hack in 2010, when the target was the Nasdaq stock market. According to an extensive investigation by Bloomberg Businessweek in 2014, the NSA and FBI made numerous mistakes over many months that stretched to nearly a year. “After months of work,” the article said, “there were still basic disagreements in different parts of government over who was behind the incident and why.”  There was no consensus­, with just a 70 percent certainty that the hack was a cybercrime. Months later, this determination was revised again: It was just a Russian attempt to spy on the exchange in order to design its own. The federal agents also considered the possibility that the Nasdaq snooping was not connected to the Kremlin. Instead, “someone in the FSB could have been running a for-profit operation on the side, or perhaps sold the malware to a criminal hacking group.” Again, that’s why it’s necessary to better understand the role of Guccifer 2.0 in releasing the Democratic National Committee and Clinton campaign emails before launching any cyberweapons.

he message arrived at night and consisted of three words: “Good evening sir!” The sender was a hacker who had written a series of provocative memos at the National Security Agency. His secret memos had explained — with an earthy use of slang and emojis that was unusual for an operative of the largest eavesdropping organization in the world — how the NSA breaks into the digital accounts of people who manage computer networks, and how it tries to unmask people who use Tor to browse the web anonymously. Outlining some of the NSA’s most sensitive activities, the memos were leaked by Edward Snowden, and I had written about a few of them for The Intercept. There is no Miss Manners for exchanging pleasantries with a man the government has trained to be the digital equivalent of a Navy SEAL. Though I had initiated the contact, I was wary of how he might respond. The hacker had publicly expressed a visceral dislike for Snowden and had accused The Intercept of jeopardizing lives by publishing classified information. One of his memos outlined the ways the NSA reroutes (or “shapes”) the internet traffic of entire countries, and another memo was titled “I Hunt Sysadmins.” I felt sure he could hack anyone’s computer, including mine. Good evening sir!

I got lucky with the hacker, because he recently left the agency for the cybersecurity industry; it would be his choice to talk, not the NSA’s. Fortunately, speaking out is his second nature.

Ever wonder why most e-mail clients hide images by default? The reason for the "display images" button is because images in an e-mail must be loaded from a third-party server. For promotional e-mails and spam, usually this server is operated by the entity that sent the e-mail. So when you load these images, you aren't just receiving an image—you're also sending a ton of data about yourself to the e-mail marketer. Loading images from these promotional e-mails reveals a lot about you. Marketers get a rough idea of your location via your IP address. They can see the HTTP referrer, meaning the URL of the page that requested the image. With the referral data, marketers can see not only what client you are using (desktop app, Web, mobile, etc.) but also what folder you were viewing the e-mail in. For instance, if you had a Gmail folder named "Ars Technica" and loaded e-mail images, the referral URL would be "https://mail.google.com/mail/u/0/#label/Ars+Technica"—the folder is right there in the URL. The same goes for the inbox, spam, and any other location. It's even possible to uniquely identify each e-mail, so marketers can tell which e-mail address requested the images—they know that you've read the e-mail. And if it was spam, this will often earn you more spam since the spammers can tell you've read their last e-mail.

But Google has just announced a move that will shut most of these tactics down: it will cache all images for Gmail users. Embedded images will now be saved by Google, and the e-mail content will be modified to display those images from Google's cache, instead of from a third-party server. E-mail marketers will no longer be able to get any information from images—they will see a single request from Google, which will then be used to send the image out to all Gmail users. Unless you click on a link, marketers will have no idea the e-mail has been seen. While this means improved privacy from e-mail marketers, Google will now be digging deeper than ever into your e-mails and literally modifying the contents. If you were worried about e-mail scanning, this may take things a step further. However, if you don't like the idea of cached images, you can turn it off in the settings. This move will allow Google to automatically display images, killing the "display all images" button in Gmail. Google servers should also be faster than the usual third-party image host. Hosting all images sent to all Gmail users sounds like a huge bandwidth and storage undertaking, but if anyone can do it, it's Google. The new image handling will rollout to desktop users today, and it should hit mobile apps sometime in early 2014. There's also a bonus side effect for Google: e-mail marketing is advertising. Google exists because of advertising dollars, but they don't do e-mail marketing. They've just made a competitive form of advertising much less appealing and informative to advertisers. No doubt Google hopes this move pushes marketers to spend less on e-mail and more on Adsense.

The Federal Communications Commission is poised to ruin the free Internet on a technicality. The group is expected to introduce new net neutrality laws that would allow companies to pay for better access to consumers through deals similar to the one struck by Netflix and Comcast earlier this year. The argument is that those deals don’t technically fall under the net neutrality umbrella, so these new rules won’t apply to them even though they directly affect the Internet. At least the commission is being upfront about its disinterest in protecting the free Internet.

The Verge notes that the proposed rules will offer some protections to consumers: The Federal Communication Commission’s proposal for new net neutrality rules will allow internet service providers to charge companies for preferential treatment, effectively undermining the concept of net neutrality, according to The Wall Street Journal. The rules will reportedly allow providers to charge for preferential treatment so long as they offer that treatment to all interested parties on “commercially reasonable” terms, with the FCC will deciding whether the terms are reasonable on a case-by-case basis. Providers will not be able to block individual websites, however. The goal of net neutrality rules is to prevent service providers from discriminating between different content, allowing all types of data and all companies’ data to be treated equally. While it appears that outright blocking of individual services won’t be allowed, the Journal reports that some forms of discrimination will be allowed, though that will apparently not include slowing down websites.

Re/code summarizes the discontent with these proposed rules: Consumer groups have complained about that plan because they’re worried that Wheeler’s rules may not hold up in court either. A federal appeals court rejected two previous versions of net neutrality rules after finding fault in the FCC’s legal reasoning. During the latest smackdown, however, the court suggested that the FCC had some authority to impose net neutrality rules under a section of the law that gives the agency the ability to regulate the deployment of broadband lines. Internet activists would prefer that the FCC just re-regulate Internet lines under old rules designed for telephone networks, which they say would give the agency clear authority to police Internet lines. Wheeler has rejected that approach for now. Phone and cable companies, including Comcast, AT&T and Verizon, have vociferously fought that idea over the past few years.

As fast as it can, Google is sealing up cracks in its systems that Edward J. Snowden revealed the N.S.A. had brilliantly exploited. It is encrypting more data as it moves among its servers and helping customers encode their own emails. Facebook, Microsoft and Yahoo are taking similar steps.

After years of cooperating with the government, the immediate goal now is to thwart Washington — as well as Beijing and Moscow. The strategy is also intended to preserve business overseas in places like Brazil and Germany that have threatened to entrust data only to local providers. Google, for example, is laying its own fiber optic cable under the world’s oceans, a project that began as an effort to cut costs and extend its influence, but now has an added purpose: to assure that the company will have more control over the movement of its customer data.

A year after Mr. Snowden’s revelations, the era of quiet cooperation is over. Telecommunications companies say they are denying requests to volunteer data not covered by existing law. A.T.&T., Verizon and others say that compared with a year ago, they are far more reluctant to cooperate with the United States government in “gray areas” where there is no explicit requirement for a legal warrant.

Much to the disappointment of the digital advertising establishment, Mozilla is going ahead with plans to automatically block third-party cookie tracking in its Firefox browser. Mozilla first announced its Do Not Track browser in February, only to back off in May saying it needed to do more testing. But that didn't stop a growing chorus of loud protests from the advertising community, which argued that the browser would choke off the ad-supported Internet. The Interactive Advertising Bureau's general counsel Mike Zaneis called Mozilla's browser nothing less than a "nuclear first strike" against the ad community. No date has been set for when Firefox will turn on the feature, but advertisers, which have been regularly meeting with Mozilla and were hopeful for a compromise, are already lashing back at Mozilla.

"It's troubling," said Lou Mastria, the managing director for the Digital Advertising Alliance, which manages an online self-regulatory program called Ad Choices that provides consumers with the choice to opt-out of targeted ads. "They're putting this under the cloak of privacy, but it's disrupting a business model," Mastria said. Advertisers are worried that Mozilla's plans could be the death knell to thousands of small Web publishers that depend on third-party targeted ads to stay in business. Nearly 1,000 signed a petition urging Mozilla to change its plans.  "One publisher said that 20 percent of their business would go away. That's huge," said Mastria. "Mozilla is really picking business model winners and losers."

Not all cookies will be blocked under Mozilla's latest plans for its proposed browser; there will be exceptions. Through a partnership with the Center for Internet and Society at Stanford Law School, the two are launching a Cookie Clearinghouse. Overseen by a six-person panel, it will determine a list of undesirable cookies and then block those. "The Cookie Clearinghouse will create, maintain and publish objective information," Aleecia McDonald, director of privacy at CIS, said in a statement. "Web browser companies will be able to choose to adopt the lists we publish to provide new privacy options to their users." But others say the approach is far from objective. "What these organizations and the privacy groups that back them are really saying is 'let us choose for you because we know best,' " said Daniel Castro, a senior analyst with the Information Technology and Innovation Foundation. "The proponents of this model have claimed they are empowering users. ... This is basically Sarah Palin's 'Death Panels' but for the Internet."

Senate Majority Whip John Cornyn (R-Texas) on Tuesday said the upper chamber is unlikely to move on a stalled cybersecurity bill before the August recess.Senate Republican leaders, including Cornyn, had been angling to get the bill — known as the Cybersecurity Information Sharing Act (CISA) — to the floor this month.ADVERTISEMENTBut Cornyn said that there is simply too much of a time crunch in the remaining legislative days to get to the measure, intended to boost the public-private exchange of data on hackers.  “I’m sad to say I don’t think that’s going to happen,” he told reporters off the Senate floor. “The timing of this is unfortunate.”“I think we’re just running out time,” he added.An aide for Senate Majority Leader Mitch McConnell (R-Ky.) said he had not committed to a specific schedule after the upper chamber wraps up work in the coming days on a highway funding bill.Cornyn said Senate leadership will look to move on the bill sometime after the legislature returns in September from its month-long break.

The move would delay yet again what’s expected to be a bruising floor fight about government surveillance and digital privacy rights.“[CISA] needs a lot of work,” Sen. Patrick Leahy (D-Vt.), who currently opposes the bill, told The Hill on Tuesday. “And when it comes up, there’s going to have to be a lot of amendments otherwise it won’t pass.”Despite industry support, broad bipartisan backing, and potentially even White House support, CISA has been mired in the Senate for months over privacy concerns.Civil liberties advocates worry the bill would create another venue for the government’s intelligence wing to collect sensitive data on Americans only months after Congress voted to rein in surveillance powers.But industry groups and many lawmakers insist a bolstered data exchange is necessary to better understand and counter the growing cyber threat. Inaction will leave government and commercial networks exposed to increasingly dangerous hackers, they say.Sen. Ron Wyden (D-Ore.), who has been leading the chorus opposing the bill, rejoiced Tuesday after hearing of the likely delay.

“I really want to commend the advocates for the tremendous grassroots effort to highlight the fact that this bill was badly flawed from a privacy standpoint,” he told The Hill.Digital rights and privacy groups are blanketing senators’ offices this week with faxes and letters in an attempt to raise awareness of bill’s flaws.“Our side has picked up an enormous amount of support,” Wyden said.Wyden was the only senator to vote against CISA in the Senate Intelligence Committee. The panel approved the measure in March by a 14-1 vote and it looked like CISA was barrelling toward the Senate floor.After the House easily passed its companion pieces of legislation, CISA’s odds only seemed better.But the measure got tied up in the vicious debate over the National Security Agency's (NSA) spying powers that played out throughout April and May.“It’s like a number of these issues, in the committee the vote was 14-1, everyone says, ‘oh, Ron Wyden opposes another bipartisan bill,’” Wyden said Tuesday. “And I said, ‘People are going to see that this is a badly flawed bill.’”

The head of the National Security Agency on Thursday told Senate lawmakers that preventing his agency from collecting Americans’ information in bulk would make it harder to do its job.Under questioning before the Senate Intelligence Committee, Adm. Michael Rogers agreed that ending bulk collection would “significantly reduce [his] operational capabilities.”ADVERTISEMENT“Right now, bulk collection gives us the ability ... to generate insights as to what’s going on,” Rogers told the committee.The NSA head also referenced a January report from the National Academy of Sciences that concluded there is “no software technique that will fully substitute for bulk collection” because of the ability to search through the storehouse of old information. “That independent, impartial, scientifically-founded body came back and said no, under the current structure there is no real replacement,” Rogers said.Rogers was questioned on Thursday by Sen. Ron Wyden (D-Ore.), a member of the Intelligence Committee who has become its most vocal privacy hawk.

In response to the NSA head’s comments, Wyden pointed to a 2013 White House review group, which found that one controversial NSA bulk collection program “was not essential to preventing attacks” and that the information obtained by the NSA “could readily have been obtained in a timely manner using” other means.The debate follows on a congressional clash earlier this year over the NSA’s bulk collection of records about the phone calls of millions of Americans. The records contained information about whom people called and when but not what they talked about.

After a brief lapsing of some portions of the Patriot Act, Congress eventually reined in the NSA by forcing it to go through the courts to search private phone companies’ records for a narrower set of records. Many privacy advocates treated the new law, called the USA Freedom Act, as a significant victory, through national security hawks worried that it would make it harder for the NSA to track terrorists.Under the new system — which has not gone into effect yet — the amount of time it takes to obtain those records “is probably going to be longer I suspect,” Rogers said.Though the phone records database has been the NSA’s most prominent bulk collection program, it is not the only one. The agency’s collection of vast amounts of Internet data has alarmed many privacy advocates and is the target of a current lawsuit from Wikipedia and the American Civil Liberties Union. 

Activists worried about online privacy are sending Congress a message with some old-school technology: They're sending faxes -- more than 6.2 million, they claim -- to express opposition to the Cybersecurity Information Sharing Act (CISA).Why faxes? "Congress is stuck in 1984 and doesn't understand modern technology," according to the campaign Fax Big Brother. The week-long campaign was organized by the nonpartisan Electronic Frontier Foundation, the group Access and Fight for the Future, the activist group behind the major Internet protests that helped derail a pair of anti-piracy bills in 2012. It also has the backing of a dozen groups like the ACLU, the American Library Association, National Association of Criminal Defense Lawyers and others.

CISA aims to facilitate information sharing regarding cyberthreats between the government and the private sector. The bill gained more attention following the massive hack in which the records of nearly 22 million people were stolen from government computers."The ability to easily and quickly share cyber attack information, along with ways to counter attacks, is a key method to stop them from happening in the first place," Sen. Dianne Feinstein, D-California, who helped introduce CISA, said in a statement after the hack. Senate leadership had planned to vote on CISA this week before leaving for its August recess. However, the bill may be sidelined for the time being as the Republican-led Senate puts precedent on a legislative effort to defund Planned Parenthood.Even as the bill was put on the backburner, the grassroots campaign to stop it gained steam. Fight for the Future started sending faxes to all 100 Senate offices on Monday, but the campaign really took off after it garnered attention on the website Reddit and on social media. The faxed messages are generated by Internet users who visit faxbigbrother.com or stopcyberspying.com -- or who simply send a message via Twitter with the hashtag #faxbigbrother. To send all those faxes, Fight for the Future set up a dedicated server and a dozen phone lines and modems they say are capable of sending tens of thousands of faxes a day.

Fight for the Future told CBS News that it has so many faxes queued up at this point, that it may take months for Senate offices to receive them all, though the group is working on scaling up its capability to send them faster. They're also limited by the speed at which Senate offices can receive them.

Security experts call it a “drive-by download”: a hacker infiltrates a high-traffic website and then subverts it to deliver malware to every single visitor. It’s one of the most powerful tools in the black hat arsenal, capable of delivering thousands of fresh victims into a hackers’ clutches within minutes. Now the technique is being adopted by a different kind of a hacker—the kind with a badge. For the last two years, the FBI has been quietly experimenting with drive-by hacks as a solution to one of law enforcement’s knottiest Internet problems: how to identify and prosecute users of criminal websites hiding behind the powerful Tor anonymity system. The approach has borne fruit—over a dozen alleged users of Tor-based child porn sites are now headed for trial as a result. But it’s also engendering controversy, with charges that the Justice Department has glossed over the bulk-hacking technique when describing it to judges, while concealing its use from defendants. Critics also worry about mission creep, the weakening of a technology relied on by human rights workers and activists, and the potential for innocent parties to wind up infected with government malware because they visited the wrong website. “This is such a big leap, there should have been congressional hearings about this,” says ACLU technologist Chris Soghoian, an expert on law enforcement’s use of hacking tools. “If Congress decides this is a technique that’s perfectly appropriate, maybe that’s OK. But let’s have an informed debate about it.”

The FBI’s use of malware is not new. The bureau calls the method an NIT, for “network investigative technique,” and the FBI has been using it since at least 2002 in cases ranging from computer hacking to bomb threats, child porn to extortion. Depending on the deployment, an NIT can be a bulky full-featured backdoor program that gives the government access to your files, location, web history and webcam for a month at a time, or a slim, fleeting wisp of code that sends the FBI your computer’s name and address, and then evaporates. What’s changed is the way the FBI uses its malware capability, deploying it as a driftnet instead of a fishing line. And the shift is a direct response to Tor, the powerful anonymity system endorsed by Edward Snowden and the State Department alike.

Verizon users might want to start looking for another provider. In an effort to better serve advertisers, Verizon Wireless has been silently modifying its users' web traffic on its network to inject a cookie-like tracker. This tracker, included in an HTTP header called X-UIDH, is sent to every unencrypted website a Verizon customer visits from a mobile device. It allows third-party advertisers and websites to assemble a deep, permanent profile of visitors' web browsing habits without their consent.Verizon apparently created this mechanism to expand their advertising programs, but it has privacy implications far beyond those programs. Indeed, while we're concerned about Verizon's own use of the header, we're even more worried about what it allows others to find out about Verizon users. The X-UIDH header effectively reinvents the cookie, but does so in a way that is shockingly insecure and dangerous to your privacy. Worse still, Verizon doesn't let users turn off this "feature." In fact, it functions even if you use a private browsing mode or clear your cookies. You can test whether the header is injected in your traffic by visiting lessonslearned.org/sniff or amibeingtracked.com over a cell data connection.How X-UIDH Works, and Why It's a Problem

To compound the problem, the header also affects more than just web browsers. Mobile apps that send HTTP requests will also have the header inserted. This means that users' behavior in apps can be correlated with their behavior on the web, which would be difficult or impossible without the header. Verizon describes this as a key benefit of using their system. But Verizon bypasses the 'Limit Ad Tracking' settings in iOS and Android that are specifically intended to limit abuse of unique identifiers by mobile apps.

Because the header is injected at the network level, Verizon can add it to anyone using their towers, even those who aren't Verizon customers.
