"Stalker Economy" Here to Stay
Google recently announced that it would start including individual users’ names and photos in some ads. This means that if you rate some product positively, your friends may see ads for that product with your name and photo attached—without your knowledge or consent. Meanwhile, Facebook is eliminating a feature that allowed people to retain some portions of their anonymity on its website.
These changes come on the heels of Google’s move to explore replacing tracking cookies with something that users have even less control over. Microsoft is …
A Fraying of the Public/Private Surveillance Partnership
The public/private surveillance partnership between the NSA and corporate data collectors is starting to fray. The reason is sunlight. The publicity resulting from the Snowden documents has made companies think twice before allowing the NSA access to their users’ and customers’ data.
Pre-Snowden, there was no downside to cooperating with the NSA. If the NSA asked you for copies of all your Internet traffic, or to put backdoors into your security software, you could assume that your cooperation would forever remain secret. To be fair, not every corporation cooperated willingly. Some fought in court. But it seems that a lot of them, telcos and backbone providers especially, were happy to give the NSA unfettered access to everything. Post-Snowden, this is changing. Now that many companies’ cooperation has become public, they’re facing a PR backlash from customers and users who are upset that their data is flowing to the NSA. And this is costing those companies business…
Leakers and Governments Should Work Together
In the Information Age, it’s easier than ever to steal and publish data. Corporations and governments have to adjust to their secrets being exposed, regularly.
When massive amounts of government documents are leaked, journalists sift through them to determine which pieces of information are newsworthy, and confer with government agencies over what needs to be redacted.
Managing this reality is going to require that governments actively engage with members of the press who receive leaked secrets, helping them secure those secrets—even while being unable to prevent them from publishing. It might seem abhorrent to help those who are seeking to bring your secrets to light, but it’s the best way to ensure that the things that truly need to be secret remain secret, even as everything else becomes public…
The Battle for Power on the Internet
Distributed citizen groups and nimble hackers once had the edge. Now governments and corporations are catching up. Who will dominate in the decades ahead?
We’re in the middle of an epic battle for power in cyberspace. On one side are the traditional, organized, institutional powers such as governments and large multinational corporations. On the other are the distributed and nimble: grassroots movements, dissident groups, hackers, and criminals. Initially, the Internet empowered the second side. It gave them a place to coordinate and communicate efficiently, and made them seem unbeatable. But now, the more traditional institutional powers are winning, and winning big. How these two sides fare in the long term, and the fate of the rest of us who don’t fall into either group, is an open question—and one vitally important to the future of the Internet…
Why the NSA's Defense of Mass Data Collection Makes No Sense
The basic government defense of the NSA’s bulk-collection programs—whether it be the list of all the telephone calls you made, your email address book and IM buddy list, or the messages you send your friends—is that what the agency is doing is perfectly legal, and doesn’t really count as surveillance, until a human being looks at the data.
It’s what Director of National Intelligence James R. Clapper meant when he lied to Congress. When asked, “Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?” he replied, “No sir, not wittingly.” To him, the definition of “collect” requires that a human look at it. So when the NSA collects—using the dictionary definition of the word—data on hundreds of millions of Americans, it’s not …
How to Design—And Defend Against—The Perfect Security Backdoor
We already know the NSA wants to eavesdrop on the internet. It has secret agreements with telcos to get direct access to bulk internet traffic. It has massive systems like TUMULT, TURMOIL, and TURBULENCE to sift through it all. And it can identify ciphertext—encrypted information—and figure out which programs could have created it.
But what the NSA wants is to be able to read that encrypted information in as close to real-time as possible. It wants backdoors, just like the cybercriminals and less benevolent governments do.
And we have to figure out how to make it harder for them, or anyone else, to insert those backdoors…
Your Life, Under Constant Surveillance
Historically, surveillance was difficult and expensive.
Over the decades, as technology advanced, surveillance became easier and easier. Today, we find ourselves in a world of ubiquitous surveillance, where everything is collected, saved, searched, correlated and analyzed.
But while technology allowed for an increase in both corporate and government surveillance, the private and public sectors took very different paths to get there. The former always collected information about everyone, but over time, collected more and more of it, while the latter always collected maximal information, but over time, collected it on more and more people…
Want to Evade NSA Spying? Don’t Connect to the Internet
Since I started working with Snowden’s documents, I have been using a number of tools to try to stay secure from the NSA. The advice I shared included using Tor, preferring certain cryptography over others, and using public-domain encryption wherever possible.
I also recommended using an air gap, which physically isolates a computer or local network of computers from the internet. (The name comes from the literal gap of air between the computer and the internet; the word predates wireless networks.)
But this is more complicated than it sounds, and requires explanation…
NSA and GCHQ target Tor Network That Protects Anonymity of Web Users
The National Security Agency has made repeated attempts to develop attacks against people using Tor, a popular tool designed to protect online anonymity, despite the fact the software is primarily funded and promoted by the US government itself.
Top-secret NSA documents, disclosed by whistleblower Edward Snowden, reveal that the agency’s current successes against Tor rely on identifying users and then attacking vulnerable software on their computers. One technique developed by the agency targeted the Firefox web browser used with Tor, giving the agency full control over targets’ computers, including access to files, all keystrokes and all online activity…
Attacking Tor: How the NSA Targets Users' Online Anonymity
Secret servers and a privileged position on the internet's backbone used to identify users and attack target computers
The online anonymity network Tor is a high-priority target for the National Security Agency. The work of attacking Tor is done by the NSA‘s application vulnerabilities branch, which is part of the systems intelligence directorate, or SID. The majority of NSA employees work in SID, which is tasked with collecting data from communications systems around the world.
According to a top-secret NSA presentation provided by the whistleblower Edward Snowden, one successful technique the NSA has developed involves exploiting the Tor browser bundle, a collection of programs designed to make it easy for people to install and use the software. The trick identified Tor users on the …
