Jumping the Paywall: How to freely share research without being arrested. This workshop will identify and address two safety-critical problems permeating research today: lack of total free access to scholarship, and the looming threat of apprehension for trying to facilitate said free access. The workshop will hypothesize workable solutions to the stated problem sets by presenting actionable intelligence and exploring tactical modes of engagement in the on-going copyfight via the exploration of securing free access to scholarship (in the form of academic e-journal articles and e-books), and via developing avoidance strategies to forego existent and emergent threats of apprehension resulting from participation in the practices of free access. Topics covered will include: --> Content access procurement --> Operational security during field deployment --> Watermark, metadata and content-protection identification and removal --> Content distribution Huh? Ever try to view a journal article only to slam into an extortionate paywall? Then you should stop by. Where? PSH (NAB) 314 Goldsmiths, University of London https://www.gold.ac.uk/find-us/ When? Date: Friday, 24 April 2015 Time: 15.00-17.00

Hi everybody. Have you seen the next Barbie Doll called 'hello Barbie. It has a microphone and wi-fi conection, when the kids talk to 'her' the talking is sent to a server where the answers of Barbie are written and improved. Of course there'll be an app for the parents to later listen the chats of their kids with Barbie. I think is not necessary to point out the implications of the subject

New Jersey Police Officer Caught Selling Bitcoin Mining Equipment
by L0R3NZ 5Z4B0 21 Apr '15

I have a long-time fascination for all things LE & military. One of the most intriguing ideas is LE or military “operators” switching sides from “good to bad" – be it in real-life or in fiction. Of course getting older (and less naive I guess) I realise it is not about switching sides: it is about all things being grey instead of black vs white separated by a thin blue line. (My favourite examples are gang members infiltrating the US military and of course the Los Zetas founded by former members of the Mexican army: the "most technologically advanced, sophisticated, and dangerous cartel operating in Mexico.” Current examples that got my attention: no.1 Teresa Shea, James Shea, DRS Signal Solutions and Oplnet LLC and no.2 Carl Mark Force IV.) Now, this little story below: New Jersey Police Officer Caught Selling Bitcoin Mining Equipment. I believe we will read a lot about such in coming months and years. Interesting times for Cypherpunks and Crypto Anarchists… – BizDevCon ### New Jersey Police Officer Caught Selling Bitcoin Mining Equipment http://www.newsbtc.com/2015/04/21/new-jersey-police-officer-caught-selling-… A New Jersey cop Vincent Saggesse, 32, who works for the Plainfield PD and is a member of the Union County SWAT Team, has been caught selling stolen Bitcoin mining equipment in an undercover sting operation. Somerset County Prosecutor Geoffrey Soriano revealed that the disgraced police officer met twice with an undercover agent to work out a sale agreement of the hot KnCMiner Neptune units. However, it is yet to be discovered whether the cop had a clear idea of what he was selling. Soriano also desisted from disclosing the source of the units. The dishonest law enforcement officers seem to be warming up to Bitcoin for their personal gains. Just three weeks back, two former federal agents were convicted of stealing Bitcoins during the federal investigations of the online black market Silk Road. The reason for police officers dirtying their hands by illegal Bitcoin activities may be that since the government is not yet fully interested in the cryptocurrency, they hope to find an easy escape route. Saggesse’s boss and Plainfield police director Carl Riley said, “I, of course, am very disappointed regarding the circumstances, and I’m sure his colleagues are disappointed as well.” The police department has taken strong action against Vincent – charged him with Official Misconduct 2nd Degree and Receiving Stolen Property 3rd Degree – and suspended him without pay, pending the disposition of the case. The charges of official misconduct were levied because Saggesse was involved in another crime – receiving $250 in bribe from the undercover agent in exchange for giving him certain details which included address of a license plate owner along with a photo. To this, the Somerset Prosecutor said, “Such information is available to law enforcement officers through various computer platforms that are to be used solely for law enforcement purposes.”

What Exactly Is Encryption?

http://www.wsj.com/articles/encryption-uncoded-a-consumers-guide-1429499476… What Exactly Is Encryption? Encryption turns messages into a string of unreadable characters. Photo: Getty Images By Elizabeth Dwoskin April 19, 2015 11:11 p.m. ET In times like these, it’s easy to be paranoid. Concerned by reports of hacking, data breaches and government spying, companies and consumers are looking for better ways to protect their data. Many are turning to encryption, a method of encoding messages that goes back millennia. Encryption is commonly used to secure online banking sessions and to protect credit-card data. But for the average computer user, it remains a mystery. Here’s a brief guide to help readers unlock its secrets. How does encryption work? If you saw the recent movie “The Imitation Game,” you’ve seen a rudimentary, by modern standards, form of encryption. During World War II, the Germans used a machine to turn military messages into coded strings of symbols. These days, computers running complex mathematical formulas can do the same thing much faster, and the codes are much harder to crack. What’s it used for? If you’ve ever done banking online, you may have noticed a “lock” icon in the address bar, or that the bar turned green. That means the browser session is encrypted by your bank. Consumers can download a growing crop of encryption tools for texting, browsing sessions and video and phone calls. Users usually must download an app or install software that scrambles messages as they are sent. (The recipient needs to be using the same app or software to unscramble the message.) Apple has started encrypting personal data on its latest mobile operating system, iOS 8. This means an outsider who hacks into a device or into Apple’s servers would see a string of unreadable characters instead of actual messages or FaceTime videos. Can I encrypt email messages? Yes, but it’s tricky. Sender and receiver must use the same type of encryption. If you have encryption switched on, but the friend you’re emailing doesn’t have it, he or she won’t be able to read your message. Since the revelations of former National Security Agency contractor Edward Snowden about electronic eavesdropping by the NSA, big tech companies have made moves to add encryption. Yahoo Inc. and Google Inc. both have announced plans to begin encrypting emails of users of their services, but the projects are moving slowly. Can encryption really protect me from getting hacked? ENLARGE Maybe. If a hacker obtains the encryption keys, or the formula that unlocks the code, all that encrypting was for naught. And that happens all the time in corporate data breaches, says Avivah Litan, a vice president and senior analyst focusing on security issues at market-research firm Gartner Inc. For example, as part of the 2007 breach at TJX Cos., hackers stole a TJX point-of-sale card-reader system and brought it home. The hackers were able to break the code used to encrypt card transactions and stole data from tens of millions of customer accounts. How can I get started? In addition to Apple’s built-in encryption in its new mobile devices, Android users can download WhatsApp, which encrypts text messages. WhatsApp, a company owned by Facebook Inc., says it is working on offering encryption for all communication sent between WhatsApp users, including images, audio and text. A number of vendors—including Voltage Security Inc., Protegrity and RSA Security, a unit of EMC Corp. —offer encryption of corporate data, including email and credit-card records. Silent Circle’s Blackphone is a phone for corporate users that can send encrypted voice calls, text, emails and other data—if both parties are using a Blackphone. Why isn’t everything encrypted? There are plenty of reasons. Encryption is time-consuming and difficult to implement. It’s hard to properly manage who has access to encryption keys, and it slows system performance. Ms. Dwoskin is a reporter in the San Francisco bureau of The Wall Street Journal.

Fwd: [tor-talk] Clarification of Tor's involvement with DARPA's Memex

Hi Thomas, Thanks for asking. I apologize for not explaining these answers earlier. I'm still trying to find the right balance for my time between mentoring people in the Tor community vs better broader communication too. Let me give you some background, and then I'll answer your question. First of all, yes indeed we've been getting some funding from the Memex project. This is what has allowed us to pay attention to and move forward on some of the really cool things we've been working on lately for hidden services: * Fixing many performance and consistency problems with hidden services, e.g.: https://trac.torproject.org/projects/tor/ticket/11447 https://trac.torproject.org/projects/tor/ticket/13211 https://trac.torproject.org/projects/tor/ticket/13447 https://trac.torproject.org/projects/tor/ticket/13700 https://trac.torproject.org/projects/tor/ticket/14219 https://trac.torproject.org/projects/tor/ticket/14224 * Fleshing out the design and analysis for the "direct onion service" option that folks like Facebook want: https://lists.torproject.org/pipermail/tor-dev/2015-April/008625.html plus discussing other tradeoffs between upcoming design choices: https://lists.torproject.org/pipermail/tor-dev/2015-April/008597.html * The work to let Tor controllers configure a hidden service directly without using the torrc file, which the Globaleaks folks (among others) are really excited to start using: https://trac.torproject.org/projects/tor/ticket/6411 * The privacy-preserving statistics that let us conclude numbers like "3-4% of Tor traffic is hidden service related" and "there are around 30000 hidden services today": https://blog.torproject.org/blog/some-statistics-about-onions * Assessing, triaging, and putting out new Tor releases to fix hidden service security (stability) bugs recently: https://blog.torproject.org/blog/tor-02512-and-0267-are-released * I hear that Rob Jansen and others have been working on a more realistic replacement for TorPerf (https://gitweb.torproject.org/torperf.git) which will let us measure performance to a hidden service over time and better understand where the bottlenecks are. * I've also been talking to EFF about kicking off a Tor Onion Challenge (to follow on from their Tor Relay Challenges), to a) get many people to make their website or other service accessible as an onion site, and b) come up with and/or build a novel use of onion services, to go with the quite cool list that we have already but have done a poor job of publicizing: Pond, Globaleaks, SecureDrop, Ricochet, OnionShare, facebook's https onion, etc. You see, I used to be on the "making your normal website reachable as an onion service is stupid" side of the fence, but I have since come to realize that I was wrong. You know how, ten years ago, website operators would say "I don't need to offer https for my site, because my users ____" and they'd have some plausible-sounding excuse? And now they sound selfish and short-sighted if they say that, because everybody knows it should be the choice of the *user* what security properties she gets when reaching a service? I now think onion services are exactly in that boat: today we have plenty of people saying "I don't need to offer a .onion for my site, because my users _____". We need to turn it around so sites let their *users* decide what security (encryption, authentication, trust) properties they want to achieve while interacting with each site. Our "3-4%" stat has actually been used by some of the other people (at other groups) who are funded by Memex. They're talking to (among others) the child porn division of the Department of Justice, and I've taught them enough about Tor that they've basically turned into Tor advocates on our behalf. They've found actual numbers to be really useful at countering the FUD that some government people start out with. One of these people explained to me last week that they listen to her more than she thinks they'd listen to me, since she shows up as a neutral party. In any case I am happy to have more people working on the "teach law enforcement how Tor actually works" topic, which you can read more about here: https://blog.torproject.org/blog/trip-report-tor-trainings-dutch-and-belgia… https://blog.torproject.org/blog/trip-report-october-fbi-conference We do indeed need to be very careful and very thoughtful about what things in the Tor network are safe to measure. The general heuristic we've been using so far is: "Is that measurement taking advantage of something that you could instead fix? If so, it's not ok to measure it." A prime example here of what's over the line is running relays that get the HSDir flag and then recording what hidden service descriptors they see (and thus what hidden services they learn about). We would instead like to treat that as a vulnerability and fix it: https://trac.torproject.org/projects/tor/ticket/8106 https://trac.torproject.org/projects/tor/ticket/8243 https://trac.torproject.org/projects/tor/ticket/8244 and see also the "Attacks by Hidden Service Directory Servers" section of https://blog.torproject.org/blog/hidden-services-need-some-love as well as the section after it. (There are other researchers who have used that technique, e.g. http://freehaven.net/anonbib/#oakland2013-trawling and also Gareth Owen's talk at 31c3. But we need to hold ourselves to a higher standard.) On the other hand, if people publish a .onion address on a normal website and Google runs across it and indexes the name, then it seems clear that that's public information. There are many other ways to learn about hidden service names which are ethically in-between, e.g. http://blogs.verisigninc.com/blog/entry/new_from_verisign_labs_measuring1 These are great topics for us as a community to keep discussing. Similarly, if your .onion address is public, and your webserver doesn't require any authentication, and somebody fetches the content on it... that also seems like public information. And if, for example, the onion service is a forum, and users go there and then write their names down or provide other identifying information, that isn't really a bug or design flaw that Tor can fix. These days there are services like Ahmia that list and index a bunch of onion names and content: https://ahmia.fi/search/ And to be clear, I think this is a great trend: we need to make onion services easier to understand and more accessible (and faster and more robust) for ordinary people, or we'll remain stuck with all the metaphors that include the word 'dark'. Ok, now that I've provided some background, I should try to answer your question more clearly: we're using the Memex money to make hidden services stronger, and we're teaching other people how Tor works. In terms of teaching, it's the same thing I do for every other audience: explain about all the projects Tor works on (Tor, Tor Browser, pluggable transports, metrics, OONI, ...), which projects do what, how to measure and assess Tor's anonymity, what problems we don't have great answers for, and so on. Part of making Tor work better means that it works better for these people too. And some of these people are indeed working on tools to gather and organize public content from hidden services, with the intent that groups like law enforcement will find their tools useful. We're not working on these tools, but when Tor becomes better (for everybody) these tools work better (for the groups they have in mind). It is a tricky balance, but I think we have the balance right in this case. Would I rather have funding where it's easier to find a good balance? Absolutely. That's a major part of why we've been talking about funding and funding diversity so much lately, and why we've been thinking about crowdfunding specifically for hidden service design improvements, and about growing our donation base and sustainability through donations and other avenues. We need help from all of you to get there. I don't want to play the "they'd do it anyway" card too strongly here -- first because who knows, maybe they wouldn't, and second because there are definitely some activities that you stay away from no matter the balance. I've talked a lot with the program manager of Memex, and he's completely supportive of the "don't weaken Tor" mandate. In that sense we're aligned: he very strongly believes that weakening Tor would screw up this balance. I trust his intentions, and in any case we're the ones doing the technical side of Tor so we can make sure that we do the right thing. I should also make clear my opinion on some of the bad uses of Tor. The folks who are using Tor for child porn, even though they are a tiny fraction of overall Tor users, are greatly hurting Tor -- by changing or reinforcing public perceptions of what privacy is for, and also by attracting the attention and focus of law enforcement and making that the way that law enforcement first learns about Tor. So, fuck them, they should get off our network, that's not what Tor is for and they're hurting all of us. Now, that doesn't mean we should weaken Tor, even if we don't want them on the network. That slope is too easy to slip down, and we must not get into the business of dictating what is acceptable behavior for Tor users (which would eventually lead to designing technical mechanisms to enforce these choices). I just went back to re-read the Forbes article, and in retrospect it sure makes it look like all of these companies are working on tools that relate to Tor hidden services. They aren't. The main focus for Memex is on automatically parsing and collecting info from ads on e.g. craigslist, and generally getting better at the 'big data' side of searching and organizing this data. More generally, Memex is made up of a bunch of different companies, each doing their thing. I guess this is another casualty of the ambiguity of the phrases 'dark web' and 'deep web', since journalists find them hot to talk about but nobody reliably knows what they refer to. If you want to follow along with the actual technical work we're doing, I invite you to observe or participate in the periodic "SponsorR" meetings that happen on IRC: https://trac.torproject.org/projects/tor/wiki/org/sponsors/SponsorR http://meetbot.debian.net/tor-dev/ Thanks, --Roger

Safe is a relative term. One of the things that makes the RPi 'safer' is its lack of a BIOS to exploit. As for SoCs I view them as inherently less safe than less integrated CPUs. WW
