In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce "export-grade" (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA "black budget" (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it's likely NSA has been breaking 1024-bit Diffie-Hellman for some time now. The good news is, in the time since this research was originally published, the major browser vendors (IE, Chrome, and Firefox) have removed support for 512-bit Diffie-Hellman, addressing the biggest vulnerability. However, 1024-bit Diffie-Hellman remains supported for the forseeable future despite its vulnerability to NSA surveillance. In this post, we present some practical tips to protect yourself from the surveillance machine, whether you're using a web browser, an SSH client, or VPN software.

Several prominent figures, including Web inventor Tim Berners-Lee, warned the EU Parliament that its proposed censorship measure would begin transforming the Internet from an open platform for sharing and innovation, into a tool for the automated surveillance and control of its users.

For much of the year, independent media has felt the sting of increased social media censorship, as the “revolving door” between U.S. intelligence agencies and social-media companies has manifested in a crackdown on news that challenges official government narratives. With many notable independent news websites having shut down since then as a result, those that remain afloat are being censored like never before, with social media traffic from Facebook and Twitter completely cut off in some cases. Among such websites, social media censorship by the most popular social networks is now widely regarded to be the worst it has ever been – a chilling reality for any who seek fact-based perspectives on major world events that differ from those to be found on well-known corporate-media outlets that consistently toe the government line. Last August, MintPress reported that a new Google algorithm targeting “fake news” had quashed traffic to many independent news and advocacy sites, with sites such as the American Civil Liberties Union, Democracy Now, and WikiLeaks, seeing their returns from Google searches experience massive drops. The World Socialist Website, one of the affected pages, reported a 67 percent decrease in Google returns while MintPress experienced an even larger decrease of 76 percent in Google search returns. The new algorithm targeted online publications on both sides of the political spectrum critical of U.S. imperialism, foreign wars, and other long-standing government policies. Now, less than a year later, the situation has become even more dire. Several independent media pages have reported that their social media traffic has sharply declined since March and – in some cases – stopped almost entirely since June began. For instance, independent media website Antimedia – a page with over 2 million likes and follows – saw its traffic drop from around 150,000 page views per day earlier this month to around 12,000 as of this week. As a reference, this time last year Antimedia’s traffic stood at nearly 300,000 a day.

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.

The Web was designed to bring people together and make knowledge freely available. It has changed the world for good and improved the lives of billions. Yet, many people are still unable to access its benefits and, for others, the Web comes with too many unacceptable costs. Everyone has a role to play in safeguarding the future of the Web. The Contract for the Web was created by representatives from over 80 organizations, representing governments, companies and civil society, and sets out commitments to guide digital policy agendas. To achieve the Contract’s goals, governments, companies, civil society and individuals must commit to sustained policy development, advocacy, and implementation of the Contract text.

A definitive guide to verifying digital content for emergency coverage Authored by leading journalists from the BBC, Storyful, ABC, Digital First Media and other verification experts, the Verification Handbook is a groundbreaking new resource for journalists and aid providers. It provides the tools, techniques and step-by-step guidelines for how to deal with user-generated content (UGC) during emergencies.
