Security News is an archive of curated EFF Deeplinks posts for trainers, technologists, and educators who teach digital security.
Issues that we track here include: country-specific policy updates on security and privacy, updates on malware and vulnerabilities, discussions on encryption and privacy-protecting tools, updates on surveillance (corporate surveillance, street-level surveillance, and mass surveillance), device searches by law and border enforcement, tracking via devices, and general digital security tips.
If you follow security on the Internet, you may have seen articles warning you to “beware of public Wi-Fi networks" in cafes, airports, hotels, and other public places. But now, due to the widespread deployment of HTTPS encryption on most popular websites, advice to avoid public Wi-Fi is mostly out of date and applicable to a lot fewer people than it once was.
The advice stems from the early days of the Internet, when most communication was not encrypted. At that time, if...Read More
Ring isn't just a product that allows users to surveil their neighbors. The company also uses it to surveil its customers.
An investigation by EFF of the Ring doorbell app for Android found it to be packed with third-party trackers sending out a plethora of customers’ personally identifiable information (PII). Four main analytics and marketing companies were discovered to be receiving information such as the names, private IP addresses, mobile network carriers, persistent...Read More
Here at EFF, we maintain a repository of self-help resources on circumventing surveillance across a variety of different platforms, devices, and threat models. We call it Surveillance Self-Defense, or SSD for short.
SSD covers myriad topics, and is broken up into four main sections:Basics: Overviews on what digital surveillance is and how you can fight it. And if you don’t understand a term being used, there’s an extensive glossary at your disposal. Tool Guides:... Read More
UPDATE (11/8/2019): We have clarified that the NordVPN user credentials impacted were not in result of this breach.
The popular VPN provider, NordVPN, recently announced a server breach at a third-party data center. NordVPN reassured users that its key services were not impacted by this breach in particular, however, NordVPN users credentials were used with credential stuffing attacks. NordVPN stresses that there is no indication the breach and the credential stuffing...Read More
Companies Can Still Do More to Protect Privacy in Brazil: Internet Lab Releases Fourth "Who Defends Your Data" Report
Internet Lab, the Brazilian independent research center, has published their fourth annual report of “Quem Defende Seus Dados?" (“Who defends your data?"), comparing policies of their local Internet Service Providers (ISPs) and how they treat users’ data after receiving government requests. Vivo (Telefónica) still takes the lead, but Tim is not far behind. Claro/NET (América Móvil), SKY (DirectTV/AT&T), and Oi also show progress compared to 2018’s...Read More
Recently, Google’s Project Zero published a report describing a newly-discovered campaign of surveillance using chains of zero day iOS exploits to spy on iPhones. This campaign employed multiple compromised websites in what is known as a “watering hole” attack. The compromised websites would automatically run the chain of exploits on anyone who visited, with the aim of installing a surveillance implant on the device. Google didn’t reveal the names of the websites or indeed who was being...Read More
Yesterday, Google Chrome, Mozilla Firefox, and Apple’s Safari browsers started blocking a security certificate previously used by Kazakh ISPs to compromise their users’ security and perform dragnet surveillance. We encourage other browsers to take similar security measures. Since the fix has been implemented upstream in Chromium, it shouldn’t take long for other Chromium-based browsers, like Brave, Opera, and Microsoft’s Edge, to do the same.What Happened, and Why Is...

Ever since mid-2017, Apple has been tackling web tracking in a big way. Various iterations of its Intelligent Tracking Prevention (ITP) technology have been introduced over the past few years in WebKit, the browser engine for Safari. ITP already protects users from tracking in various ways, but it left open a number of questions about the guidelines it uses to determine just who Apple considers a tracker, and what behavior is indicative of tracking. Last week, Apple answered...Read More
The New York Times reported that the Trump administration wants Section 215, the legal authority that allows the National Security Agency to collect Americans’ telephone records, renewed indefinitely. That’s despite earlier reports the NSA had shuttered its Call Details Record (CDR) Program because it ran afoul of the law, violated the privacy of scores of Americans, and reportedly failed to produce useful intelligence. In a letter to Congress, outgoing Director of National Intelligence...Read More
It's Panama’s turn to take a closer look at the practices of its most prominent Internet Service Providers, and how their policies support their users’ privacy. IPANDETEC, the leading digital rights NGO in Panama, has launched its first "Who Defends Your Data" (¿Quién Defiende Tus Datos?) report. The survey shines a light on the privacy practices of the main ISPs of the country: Claro (America Movil), Movistar (Telefonica), Digicel, and Más Móvil (A...Read More
Doors across the United States are now fitted with Amazon’s Ring, a combination doorbell-security camera that records and transmits video straight to users’ phones, to Amazon’s cloud—and often to the local police department. By sending photos and alerts every time the camera detects motion or someone rings the doorbell, the app can create an illusion of a household under siege. It turns what seems like a perfectly safe neighborhood into a source of anxiety and fear. This raises the...Read More
The U.S. Department of Homeland Security (DHS) and one of its component agencies, U.S. Customs and Border Protection (CBP), released a Privacy Impact Assessment [.pdf] on CBP’s practice of monitoring social media to enhance the agency’s “situational awareness.” As we’ve argued in relation to other government social media surveillance programs, this practice endangers the free speech and privacy rights of Americans.“Situational Awareness”
The Privacy Impact...Read More
As the number of migrants at the southern border has surged in the past several months, the Trump administration has turned to increasingly draconian measures as a form of deterrence. While the separation of children from their parents and housing of migrants in overcrowded and ill-equipped holding facilities have rightfully made front-page headlines, the administration’s latest effort—to conduct Rapid DNA testing on migrant families at the border—has flown under the radar. However, this...Read More
After spending nearly a week in Ecuador to learn more about the case against Swedish open source software developer Ola Bini, who was arrested here in April, EFF has found a clear consensus among the experts: the political consequences of his arrest appear to be outweighing any actual evidence the police have against him. The details of who stood to benefit from Bini's prosecution varied depending on who we spoke with, but overall we have been deeply disturbed by how intertwined the...Read More
Last week we learned about DataSpii, a report by independent researcher Sam Jadali about the “catastrophic data leak” wrought by a collection of browser extensions that surreptitiously extracted their users’ browsing history (and in some cases portions of visited web pages). Over four...Read More
Last week, Attorney General William Barr and FBI Director Christopher Wray chose to spend some of their time giving speeches demonizing encryption and calling for the creation of backdoors to allow the government access to encrypted data. You should not spend any of your time listening to them.
Don’t be mistaken; the threat to encryption remains high. Australia and the United Kingdom already have laws in place that can enable those governments to undermine encryption, while other...Read More
Grassroots-level organizing has long been an important tool for advancing policy goals and activating a constituency. More importantly, local organizing can provide an avenue through which the skills and knowledge of some are leveraged to support the previously-unmet needs of the wider community.
As a member of the Electronic Frontier Alliance—a network of independent local advocacy groups in the U.S.—The Cypurr Collective is offering down-to-earth tech guidance to their neighbors...Read More
Since academics and investigative journalists first reported last year that Facebook was using people’s two-factor authentication numbers and “shadow” contact information for targeted advertising, Facebook has shown little public interest in fixing this critical problem. Subsequent demands that Facebook stop all non-essential uses of these phone numbers, and public revelations that Facebook’s phone number abuse was even worse than initially reported, failed to move the company to...Read More
For more than a decade, consumer rights groups (including EFF) worked with technologists and companies to try to standardize Do Not Track, a flag that browsers could send to online companies signaling that their users did not want their browsing activity tracked. Despite long hours and backing from the FTC, foot-dragging from the browser vendors and outright hostility from the big online media companies mean that setting Do Not Track in your browser does virtually nothing to protect your...Read More
In its next release, Android plans to up its privacy game. But the operating system still caters to ad trackers at its users’ expense.
The newest release of Android, dubbed “Q,” is currently in late-stage beta testing and slated for a full release this summer. After a year defined by new privacy protections around the world and major privacy failures by Big Tech, this year, Google is trying to convince users that it is serious about “protecting their information.” The word...Read More
Earlier this month, the House Committee on Homeland Security held a hearing to discuss the role of face recognition and other invasive biometric technologies in use by the Department of Homeland Security (DHS). Despite some pushback from some lawmakers on the committee, John Wagner of the U.S. Customs and Border Protection (CBP), Austin Gould of the Transportation Security Administration (TSA), Joseph DiPietro of the Secret Service, and Charles Romine from the National Institute of...Read More
Derechos Digitales, the leading digital rights organization in Chile, published its third annual Who Defends Your Data report today, in collaboration with EFF. The report assesses whether the country’s top ISPs enforce privacy policies and practices that put their users first. Kurt Opsahl, EFF’s Deputy Executive Director and General Counsel, joined the launch in Santiago de Chile, which highlighted the main findings and achievements of the report.
ISPs have made...Read More
Why do we care about encryption? Why was it a big deal, at least in theory, when Mark Zuckerberg announced earlier this year that Facebook would move to end-to-end encryption on all three of its messaging platforms? We don’t just support encryption for its own sake. We fight for it because encryption is one of the most powerful tools individuals have for maintaining their digital privacy and security in an increasingly insecure world.
And although encryption may be the backbone,...Read More
The latest release of Privacy Badger gives it the power to detect and block a new class of evasive, pervasive third-party trackers, including Google Analytics.
Most blocking tools, like uBlock Origin, Ghostery, and Firefox’s native blocking mode (using Disconect’s block lists), use human-curated lists to decide whether to block or allow third-party resources. But Privacy Badger is different. Rather than rely on a list of known trackers, it discovers and learns to block new...Read More
Our phones hold a plethora of important, private information about our personal lives, and it’s not just their contents that matter: the data that our phones exchange with cell towers during basic connection procedures can reveal critical, and private, information. Perhaps you called the suicide prevention hotline from the Golden Gate Bridge; maybe you received a call from the local NRA office while it was having a campaign against gun legislation, and then called your senators and...Read More
