Cryptocurrencies and Tor hidden services ushered in a new golden age for markets in illegal goods, especially banned or circumscribed drugs: Bitcoin was widely (and incorrectly) viewed as intrinsically anonymous, while the marketplaces themselves were significantly safer and more reliable than traditional criminal markets, and as sellers realized real savings in losses due to law enforcement and related risks, the prices of their merchandise plummeted, while their profits soared.

Sumana writes, "SecureDrop (previously) (originally coded by Aaron Swartz) is an open source whistleblower submission system that media organizations can install to securely accept documents from anonymous sources. Its parent nonprofit, the Freedom of the Press Foundation (previously), is hiring a Senior Software Engineer to join the team and:" Read the rest

Getting all your data to flow through the Tor network can be tricky -- the desktop Tor Browser only tunnels your web-traffic through the privacy-protecting service, and the mobile apps can be tricky and uncertain. Read the rest

Who Left Open the Cookie Jar? A Comprehensive Evaluation of Third-Party Cookie Policies won the Distinguished Paper prize at this year's Usenix Security Conference; its authors, researchers at Belgium's Catholic University in Leuven, revealed a host of devastating, never-seen tracking techniques for identifying web-users who were using privacy tools supplied by browser-vendors and third-party tracking-blocking tools.

This week, I sat down for an hour-long interview with the Yale Privacy Lab's Sean O'Brien (MP3); Sean is a frequent Boing Boing contributor and I was honored that he invited me to be his guest on the very first episode of the Lab's new podcast. Read the rest

A presentation today at Defcon from Drexel computer science prof Rachel Greenstadt and GWU computer sicence prof Aylin Caliskan builds on the pair's earlier work in identifying the authors of software and shows that they can, with a high degree of accuracy, identify the anonymous author of software, whether in source-code or binary form.

Ben Wallach is Theresa May's security minister; he has proposed that the UK follow China's example and require that any place providing internet access use bank-account verification to affirmatively identify all the people who use the internet so they can be punished for bullying. Read the rest

Uganda's social media tax may be an unenforceable mess, but that doesn't make it harmless (it opens the door to selective enforcement and invites programs of censorship and mass surveillance in the name of fighting "tax evasion") but that's only half of dictator Yoweri Museveni's plan to control the internet.

In An Empirical Analysis of Traceability in the Monero Blockchain, a group of eminent computer scientists analyze a longstanding privacy defect in the Monero cryptocurrency, and reveal a new, subtle flaw, both of which can be used to potentially reveal the details of transactions and identify their parties.

Last week, we celebrated Data Privacy day. Everything we do online—whether on a computer or on a mobile device—is being tracked, traced, compiled, crunched, bought and sold by familiar tech-titans like Google, Facebook, Verizon and hundreds of lesser known data brokers who help advertisers build frighteningly detailed digital profiles of users by harvesting data from a variety of sources, including customer databases and online platforms. After I lecture to my students on this topic, rattling off a dozen mechanisms by which corporations and governments can spy and pry on us, threating both anonymity and privacy, their reaction is usually either indifference (because, you know, they think they have nothing to hide) or for those that I’ve convinced they should care, some measure of despair.

The New York Times is now available as an "Onion Service" on the Tor network, at the address https://www.nytimes3xbfgragh.onion/ -- meaning that anyone with Tor access can securely and privately access the Times without giving away any information about what they're looking at, even to state-level actors who control the ISPs.

Zerodium is a cyber-arms dealer that produces hacking tools for governments by buying up newly discovered defects in widely used systems, weaponizing them and then selling them to be used against criminals, activists, journalists and other targets of state surveillance. Read the rest

Security researcher Sarah Jamie Lewis wanted to demonstrate that the horrific stories of insecure networked sex-toys (and other Internet of Things devices) was the result of manufacturers' negligence, not the intrinsic limitations of information security. Read the rest

In their Defcon 25 presentation, "Dark Data", journalist Svea Eckert and data scientist Andreas Dewes described how easy it was to get a massive trove of "anonymized" browsing habits (collected by browser plugins) and then re-identify the people in the data-set, discovering (among other things), the porn-browsing habits of a German judge and the medication regime of a German MP.

If you're using an anonymity tool -- Tor or something like it -- to be anonymous on the internet, it's really easy to screw it up and do something that would allow an adversary of varying degrees of power (up to and including powerful governments) to unmask you. Read the rest

Gizmodo's Ashley Feinberg (almost certainly) figured out that James Comey's secret Twitter handle was @projectexile7, because America's top G-man failed at some of the most basic elements of operational security. Read the rest

It's one thing to set up an "anonymous" Twitter Hulk account whose anonymity your friends and colleagues can't pierce, because the combination of your care not to tweet identifying details, the stilted Hulk syntax, and your friends' inability to surveil the global internet and compel phone companies to give up their caller records suffice for that purpose.
