Imagine you are the target of a phishing attack: Someone sends you an email attachment containing malware. Your email service provider shares the attachment with the government, so that others can configure their computer systems to spot similar attacks. The next day, your provider gets a call. It’s the Department of Homeland Security (DHS), and they’re curious. The malware appears to be from Turkey. Why, DHS wants to know, might someone in Turkey be interested in attacking you? So, would your email company please share all your emails with the government? Knowing more about you, investigators might better understand the attack. Normally, your email provider wouldn’t be allowed to give this information over without your consent or a search warrant. But that could soon change. The Senate may soon make another attempt at passing the Cybersecurity Information Sharing Act, a bill that would waive privacy laws in the name of cybersecurity. In April, the US House of Representatives passed by strong majorities two similar “cyber threat” information sharing bills. These bills grant companies immunity for giving DHS information about network attacks, attackers, and online crimes.

Sharing information about security vulnerabilities is a good idea. Shared vulnerability data empowers other system operators to check and see if they, too, have been attacked, and also to guard against being similarly attacked in the future. I’ve spent most of my career fighting for researchers’ rights to share this kind of information against threats from companies that didn’t want their customers to know their products were flawed. But, these bills gut legal protections against government fishing expeditions exactly at a time when individuals and Internet companies need privacy laws to get stronger, not weaker. 

Worse, the bills aren’t needed. Private companies share threat data with each other, and even with the government, all the time. The threat data that security professionals use to protect networks from future attacks is a far more narrow category of information than those included in the bills being considered by Congress, and will only rarely contain private information. And none of the recent cyberattacks — not Sony, not Target, and not the devastating grab of sensitive background check interviews on government employees at the Office of Personnel Management — would have been mitigated by these bills.

In a pathbreaking case on Fourth Amendment privacy rights and modern technology, the Supreme Court unanimously ruled that the police must obtain warrants before searching the digital contents of cellphones taken from people who are placed under arrest. Here are some key points in the opinion by Chief Justice John G. Roberts Jr. and a concurrence by Justice Samuel Alito.

Despite the post-Snowden spotlight on mass surveillance, the intelligence community’s easiest end-run around the Fourth Amendment since 2001 has been something called a National Security Letter. FBI agents can demand that an Internet service provider, telephone company or financial institution turn over its records on any number of people — without any judicial review whatsoever — simply by writing a letter that says the information is needed for national security purposes. The FBI at one point was cranking out over 50,000 such letters a year; by the latest count, it still issues about 60 a day. The letters look like this:

Recipients are legally required to comply — but it doesn’t stop there. They also aren’t allowed to mention the order to anyone, least of all the person whose data is being searched. Ever. That’s because National Security Letters almost always come with eternal gag orders. Here’s that part:

That means the NSL process utterly disregards the First Amendment as well. More than a year ago, President Obama announced that he was ordering the Justice Department to terminate gag orders “within a fixed time unless the government demonstrates a real need for further secrecy.” And on Feb. 3, when the Office of the Director of National Intelligence announced a handful of baby steps resulting from its “comprehensive effort to examine and enhance [its] privacy and civil liberty protections” one of the most concrete was — finally — to cap the gag orders: In response to the President’s new direction, the FBI will now presumptively terminate National Security Letter nondisclosure orders at the earlier of three years after the opening of a fully predicated investigation or the investigation’s close. Continued nondisclosures orders beyond this period are permitted only if a Special Agent in Charge or a Deputy Assistant Director determines that the statutory standards for nondisclosure continue to be satisfied and that the case agent has justified, in writing, why continued nondisclosure is appropriate.

Internet service providers from around the world are lodging formal complaints against the UK government's monitoring service, GCHQ, alleging that it uses "malicious software" to break into their networks.The claims from seven organisations based in six countries – the UK, Netherlands, US, South Korea, Germany and Zimbabwe – will add to international pressure on the British government following Edward Snowden's revelations about mass surveillance of the internet by UK and US intelligence agencies.The claims are being filed with the investigatory powers tribunal (IPT), the court in London that assesses complaints about the agencies' activities and misuse of surveillance by government organisations. Most of its hearings are held at least partially in secret.

The IPT is already considering a number of related submissions. Later this month it will investigate complaints by human rights groups about the way social media sites have been targeted by GCHQ.The government has defended the security services, pointing out that online searches are often routed overseas and those deemed "external communications" can be monitored without the need for an individual warrant. Critics say that such a legal interpretation sidesteps the need for traditional intercept safeguards.The latest claim is against both GCHQ, located near Cheltenham, and the Foreign Office. It is based on articles published earlier this year in the German magazine Der Spiegel. That report alleged that GCHQ had carried out an attack, codenamed Operation Socialist, on the Belgian telecoms group, Belgacom, targeting individual employees with "malware (malicious software)".One of the techniques was a "man in the middle" attack, which, according to the documents filed at the IPT, bypasses modern encryption software and "operates by interposing the attacker [GCHQ] between two computers that believe that they are securely communicating with each other. In fact, each is communicating with GCHQ, who collect the communications, as well as relaying them in the hope that the interference will be undetected."The complaint alleges that the attacks were a breach of the Computer Misuse Act 1990 and an interference with the privacy rights of the employees under the European convention of human rights.

The organisations targeted, the submission states, were all "responsible and professional internet service providers". The claimants are: GreenNet Ltd, based in the UK, Riseup Networks in Seattle, Mango Email Service in Zimbabwe, Jinbonet in South Korea, Greenhost in the Netherlands, May First/People Link in New York and the Chaos Computer Club in Hamburg.

For most of the past six weeks, the biggest story out of Silicon Valley was Apple’s battle with the FBI over a federal order to unlock the iPhone of a mass shooter. The company’s refusal touched off a searing debate over privacy and security in the digital age. But this morning, at a small office in Mountain View, California, three guys made the scope of that enormous debate look kinda small. Mountain View is home to WhatsApp, an online messaging service now owned by tech giant Facebook, that has grown into one of the world’s most important applications. More than a billion people trade messages, make phone calls, send photos, and swap videos using the service. This means that only Facebook itself runs a larger self-contained communications network. And today, the enigmatic founders of WhatsApp, Brian Acton and Jan Koum, together with a high-minded coder and cryptographer who goes by the pseudonym Moxie Marlinspike, revealed that the company has added end-to-end encryption to every form of communication on its service.

This means that if any group of people uses the latest version of WhatsApp—whether that group spans two people or ten—the service will encrypt all messages, phone calls, photos, and videos moving among them. And that’s true on any phone that runs the app, from iPhones to Android phones to Windows phones to old school Nokia flip phones. With end-to-end encryption in place, not even WhatsApp’s employees can read the data that’s sent across its network. In other words, WhatsApp has no way of complying with a court order demanding access to the content of any message, phone call, photo, or video traveling through its service. Like Apple, WhatsApp is, in practice, stonewalling the federal government, but it’s doing so on a larger front—one that spans roughly a billion devices.

The FBI and the Justice Department declined to comment for this story. But many inside the government and out are sure to take issue with the company’s move. In late 2014, WhatsApp encrypted a portion of its network. In the months since, its service has apparently been used to facilitate criminal acts, including the terrorist attacks on Paris last year. According to The New York Times, as recently as this month, the Justice Department was considering a court case against the company after a wiretap order (still under seal) ran into WhatsApp’s end-to-end encryption. “The government doesn’t want to stop encryption,” says Joseph DeMarco, a former federal prosecutor who specializes in cybercrime and has represented various law enforcement agencies backing the Justice Department and the FBI in their battle with Apple. “But the question is: what do you do when a company creates an encryption system that makes it impossible for court-authorized search warrants to be executed? What is the reasonable level of assistance you should ask from that company?”

These and other classified documents provided by former NSA contractor Edward Snowden reveal that the NSA has developed technology not just to record and transcribe private conversations but to automatically identify the speakers. Americans most regularly encounter this technology, known as speaker recognition, or speaker identification, when they wake up Amazon’s Alexa or call their bank. But a decade before voice commands like “Hello Siri” and “OK Google” became common household phrases, the NSA was using speaker recognition to monitor terrorists, politicians, drug lords, spies, and even agency employees. The technology works by analyzing the physical and behavioral features that make each person’s voice distinctive, such as the pitch, shape of the mouth, and length of the larynx. An algorithm then creates a dynamic computer model of the individual’s vocal characteristics. This is what’s popularly referred to as a “voiceprint.” The entire process — capturing a few spoken words, turning those words into a voiceprint, and comparing that representation to other “voiceprints” already stored in the database — can happen almost instantaneously. Although the NSA is known to rely on finger and face prints to identify targets, voiceprints, according to a 2008 agency document, are “where NSA reigns supreme.” It’s not difficult to see why. By intercepting and recording millions of overseas telephone conversations, video teleconferences, and internet calls — in addition to capturing, with or without warrants, the domestic conversations of Americans — the NSA has built an unrivaled collection of distinct voices. Documents from the Snowden archive reveal that analysts fed some of these recordings to speaker recognition algorithms that could connect individuals to their past utterances, even when they had used unknown phone numbers, secret code words, or multiple languages.

The classified documents, dating from 2004 to 2012, show the NSA refining increasingly sophisticated iterations of its speaker recognition technology. They confirm the uses of speaker recognition in counterterrorism operations and overseas drug busts. And they suggest that the agency planned to deploy the technology not just to retroactively identify spies like Pelton but to prevent whistleblowers like Snowden.

he National Security Agency (NSA) collected over 530 million phone records of Americans in 2017—that's three times the amount the spy agency sucked up in 2016. The figures were released Friday in an annual report from the Office of the Director of National Intelligence (ODNI). It shows that the number of "call detail records" the agency collected from telecommunications providers during Trump's first year in office was 534 million, compared to 151 million the year prior. "The intelligence community's transparency has yet to extend to explaining dramatic increases in their collection," said Robyn Greene, policy counsel at the Open Technology Institute. The content of the calls itself is not collected but so-called "metadata," which, as Gizmodo notes, "is supposedly anonymous, but it can easily be used to identify an individual. The information can also be paired with other publicly available information from social media and other sources to paint a surprisingly detailed picture of a person's life." The report also revealed that the agency, using its controversial Section 702 authority, increased the number of foreign targets of warrantless surveillance. It was 129,080 in 2017 compared to 106,469 in 2016. As digital rights group EFF noted earlier this year, Under Section 702, the NSA collects billions of communications, including those belonging to innocent Americans who are not actually targeted. These communications are then placed in databases that other intelligence and law enforcement agencies can access—for purposes unrelated to national security—without a warrant or any judicial review. "Overall," Jake Laperruque, senior counsel at the Project On Government Oversight, said to ZDNet, "the numbers show that the scale of warrantless surveillance is growing at a significant rate, but ODNI still won't tell Americans how much it affects them."

The White House and U.S. intelligence chiefs Wednesday backed making permanent a law that allows for the collection of digital communications of foreigners overseas, escalating a fight in Congress over privacy and security. The law, enshrined in Section 702 of the Foreign Intelligence Surveillance Act, is due to expire on December 31 unless Congress votes to reauthorize it, but is considered vital by U.S. intelligence agencies. Privacy advocates have criticized the law though for allowing the incidental collection of data belonging to millions of Americans without a search warrant. The push to make the law permanent may lead to a contentious debate over renewal of Section 702 in Congress, where lawmakers in both parties are deeply divided over whether to adopt transparency and oversight reforms

Reuters reported in March that the Trump administration supported renewal of Section 702 without any changes, citing an unnamed White House official, but it was not clear at the time whether it wanted the law made permanent.
