Today we are releasing the implementation guide for EFF’s Do Not Track (DNT) policy. For years users have been able to set a Do Not Track signal in their browser, but there has been little guidance for websites as to how to honor that request. EFF’s DNT policy sets out a meaningful response for servers to follow, and this guide provides details about how to apply it in practice. At its core, DNT protects user privacy by excluding the use of unique identifiers for cross-site tracking, and by limiting the retention period of log data to ten days. This short retention period gives sites the time they need for debugging and security purposes, and to generate aggregate statistical data. From this baseline, the policy then allows exceptions when the user's interactions with the site—e.g., to post comments, make a purchase, or click on an ad—necessitates collecting more information. The site is then free to retain any data necessary to complete the transaction. We believe this approach balances users’ privacy expectations with the ability of websites to deliver the functionality users want. Websites often integrate third-party content and rely on third-party services (like content delivery networks or analytics), and this creates the potential for user data to be leaked despite the best intentions of the site operator. The guide identifies potential pitfalls and catalogs providers of compliant services. It is common, for example, to embed media from platforms like You Tube, Sound Cloud, and Twitter, all of which track users whenever their widgets are loaded. Fortunately, Embedly, which offers control over the appearance of embeds, also supports DNT via its API, displaying a poster instead and loading the widget only if the user clicks on it knowingly.

Knowledge makes the difference between willing tracking and non-consensual tracking. Users should be able to choose whether they want to give up their privacy in exchange for using a site or a  particular feature. This means sites need to be transparent about their practices. A great example of this is our biggest adopter, Medium, which does not track DNT users who browse the site and gives clear information about tracking to users when they choose to log in. This is their previous log-in panel, the DNT language is currently being added to their new interface.

The information security world is focused on two new security vulnerabilities, “Spectre” and “Meltdown”, that represent vulnerabilities embedded in computer hardware. Lawfare readers should respond in two ways: keep their operating systems up to date and, critically, install an ad-blocker for your web browser. (Here are guides on how to do so in Chrome and Firefox.) In fact, a proper response to Spectre should involve ad-blocking on all government computers. Other than that, don’t worry. Readers who just wanted to know what to do can stop reading. But for those curious about some of the technical background on these vulnerabilities and why ad-blocking is an essential security measure for a modern computer, read on.

A New York-led probe into allegations that Facebook Inc put consumer data at risk and pushed up advertising rates has expanded to include attorneys general from 47 U.S. states and territories, New York Attorney General Letitia James said in a statement on Tuesday.

The investigation of Facebook announced in September had included Colorado, Florida, Iowa, Nebraska, North Carolina, Ohio, Tennessee and the District of Columbia. It now includes most U.S. states as well as the U.S. territory of Guam.

Some states, particularly New York and Nebraska, have raised concerns that Facebook and other big tech companies engage in anti-competitive practices, expose consumer data to potential data theft and push up advertising prices.

NSO Group, an Israeli vendor of “lawful” hacking tools designed to infect a target’s phone with spyware, is regarded by many as a bad actor. The group claims to be shocked when its products are misused, as they have been in Mexico, Saudi Arabia and the United Arab Emirates. One incident might be excusable, but the group’s continued enabling of misbehavior has resulted in well-earned enmity. Recently, Facebook struck back. NSO Group deployed a weaponized exploit for Facebook’s WhatsApp messenger, integrated it into its Pegasus malcode system, and offered it to its customers (a mix of legitimate government agencies and nefarious government actors) interested in hacking WhatsApp users beginning in April. This was a particularly powerful exploit because it required no user interaction and the only sign of the exploit a user might discover would be a series of “missed calls” received on the user’s phone. Facebook patched the vulnerability on May 13, blocking the NSO campaign. Facebook wasn’t satisfied with simply closing the vulnerability. In cooperation with CitizenLab, Facebook identified more than 100 incidents in which NSO Group’s WhatsApp exploit appeared to target human rights activists and journalists. In total, Facebook and CitizenLab identified 1,400 targets (which apparently also included government officials in U.S. allied governments). They then filed a federal lawsuit against NSO Group, closed NSO Group member accounts, and, most damaging of all to NSO’s customers, sent a notice to all identified victims alerting them of the attack. This meant that all targets, both dissidents and drug lords alike, were notified of this surveillance. The lawsuit will be a case to watch. Facebook has already revealed a large amount of detail concerning NSO Group’s internal workings, including the hands-on nature of its business model: NSO Group actively assists countries in hacking targets. For example, we now know that while an NSO Group employee may not press the “Enter” key for a target, NSO employees do act to advise and consult on targeting; and NSO Group is largely responsible for running the infrastructure used to exploit targets and manage implants. Expect more revelations like this as the case proceeds.

California’s attorney general has gone to court to force Facebook to hand over documents as part of an investigation into the company. Xavier Becerra filed a “petition to enforce investigative subpoena” with the Superior Court of California in San Francisco on Wednesday morning, arguing that Facebook’s response to his subpoenas has been “patently inadequate.” Citing a “lack of cooperation” not just with his office but also the Federal Trade Commission (FTC), Xavier Becerra points out [PDF] that it took Facebook a year to respond to his initial inquiry to produce documents relating to the Cambridge Analytica scandal, where Facebook allowed a third party to access vast amounts of personal information through its systems.

Not only that but Facebook flat out refused to “search communications involving senior executives,” meaning that it refused to search for relevant information in the emails and other communications of CEO Mark Zuckerberg and COO Sheryl Sandberg, among others. “Facebook is not just continuing to drag its feet, it is failing to comply with lawfully issued subpoenas and interrogatories,” the filing states.

The filing comes the same day that 7,000 pages of internal Facebook files were published online. Those documents were obtained and leaked amid a lawsuit between Facebook and a third-party app developer and were labelled as “highly confidential” by the antisocial network. The main upshot of those files is that they show Facebook used the data it gathered on millions of its users as a business weapon: it provided people's profile information to companies that, for instance, agreed to spend hundreds of thousands of dollars on adverts within Facebook, and it cut off developers that posed a competitive threat to its ever-growing stable of companies and services (or developers that wouldn't pay up, or were just too sketchy for the internet giant.) This confirms earlier reporting. CEO Zuckerberg also continues to avoid visiting London, or anywhere in the UK, out of fear he will be arrested for repeatedly failing to comply with a request by Parliament to answer questions about Facebook’s actions, as revealed in the tranche of documents.

Six4Three recently published a playbook for the FTC to get to the bottom of Facebook’s secretive deals selling user data without privacy controls. In light of The New York Times article reporting multiple criminal investigations into Facebook surrounding these secretive deals, we’re publishing the playbook for criminal investigators.Perhaps the most important recognition at the outset is that the secretive deals that have been reported, whether those with a handful of device manufacturers or with 150 large technology companies, are just the tip of the iceberg. Those secretive deals handing over user data in exchange for gobs of cash were merely part and parcel of a much broader illegal scheme that begins with Facebook’s transition to mobile in 2012 and continues to this very day. We believe this illegal scheme amounts to a clear RICO violation. The United Kingdom Parliament agrees. Here’s how criminal investigators can overcome Facebook’s incredibly effective concealment campaign and bring a viable RICO case.Facebook’s pattern of racketeering activity is a play in three acts from at least 2012 to present. The first act is all about the desperation resulting from the collapse of Facebook’s desktop advertising business right around its IPO and the various securities violations that resulted. The second act is about covering up those securities violations by illegally building its mobile advertising business via extortion and wire fraud in order to close the gap in Facebook’s revenue projections before the world took notice, which likely resulted in additional securities violations. The third act is about covering up the extortion and wire fraud by lying to government officials investigating Facebook while continuing to effectuate the scheme. We are still in the third act.For almost a decade now Facebook has been covering up one illegal act with another in order to hide how it managed to ramp up its mobile advertising business faster than any other business in the history of capitalism. The abuses of Facebook’s data, from Russian interference in the 2016 election to Cambridge Analytica and Brexit, all stem in substantial part from the decisions Facebook knowingly, willfully and maliciously made to facilitate this criminal conspiracy. Put simply, Facebook’s transition to mobile destabilized the world.

Israel is aiming to build an international coalition to force the world’s leading social media giants to prevent their platforms from being abused to peddle incitement to terrorism. The move, which was unveiled by Public Security Minister Gilad Erdan at Sunday’s cabinet meeting, aims at requiring Facebook, Twitter, Youtube, and other social networks to take greater responsibility for such content.

While some experts consider the idea unworkable — arguing that the terms of service of such platforms protect them from any legal threat, and that the preventative measures Erdan wants to see introduced are not possible technologically, others say a coalition pushing for change could be effective, and certainly stands more of a chance than an effort led by Israel alone.

The European Union unveiled landmark legislation on Tuesday that lays out strict rules for tech giants to do business in the bloc. The draft legislation, dubbed the Digital Services Act (DSA) and the Digital Markets Act (DMA), outlines specific regulations that seek to limit the power of global internet firms on the European market. Companies including Google, Apple, Amazon, Facebook and others could face hefty penalties for violating the rules. EU antitrust czar Margrethe Vestager and EU digital chief Thierry Breton presented the draft on Tuesday, after the content of the new rules was leaked to the media on Monday.

What's in the draft laws? The dual legislation sets out a list of do's, don'ts and penalties for internet giants: Companies with over 45 million EU users would be designated as digital "gatekeepers" — making them subject to stricter regulations. Firms could be fined up to 10% of their annual turnover for violating competition rules. The could also be required to sell one of their businesses or parts of it (including rights or brands). Platforms that refuse to comply and "endanger people's life and safety" could have their service temporarily suspended "as a last resort." Companies would need to inform the EU ahead of any planned mergers or acquisitions. Certain kinds of data must be shared with regulators and rivals. Companies favoring their own services could be outlawed. Platforms would be more responsible for illegal, disturbing or misleading content.

Following the announcement on Tuesday, US internet giant Google criticized the draft legislation, saying it appeared to target specific firms.  "We will carefully study the proposals made by the European Commission over the next few days. However, we are concerned that they seem to specifically target a handful of companies," said Karan Bhatia, the vice president of government affairs and public affairs at Google. Facebook appeared to offer a more conciliatory tone, saying the legislation was "on the right track."

Federal safety regulators filed a lawsuit against Amazon on Wednesday that accuses the retail giant of refusing to recognize regulators’ authority to force the company to recall defective and unsafe products, setting up a fight over how much responsibility Amazon should take for the products it sells on its website.Support our journalism. Subscribe today.arrow-rightThe action by the Consumer Product Safety Commission comes after months of behind-the-scenes negotiations between regulators and Amazon as the agency tried to persuade the company to follow the CPSC’s rules for getting dangerous products off the market, according to a senior agency official who spoke on the condition of anonymity to comment on internal discussions.The official said Amazon officials refused to acknowledge that the CPSC has the authority to compel the company to remove unsafe products.A lawsuit was viewed as a last resort, the official added.
