Tor, the network used specifically for privacy and anonymity, just warned users of an attack meant to deanonymize people on the service. Anyone who used Tor from February 2014 through this July 4 can assume they were impacted.
Who’s behind the attacks? It appears researchers from Carnegie Mellon. Via The Verge:
The Tor team suspects the CERT division of Carnegie Mellon University’s Software Engineering Institute (SEI). Earlier this month, CERT abruptly canceled a Black Hat conference talk called “You Don’t Have to be the NSA to Break Tor: Deanonymizing Users on a Budget.” The NSA has famously attempted to break Tor, to limited success.
So what’s the big deal?: If it was the team from CERT, consider the attack a proof of concept. If they can get in, so to can more malicious actors. According to The Guardian, the CERT talk at the Black Hat conference would explain “how anyone with $3,000 could de-anonymise users of Tor.”
Somewhat related: US Government increases funding for Tor, via The Guardian.
Tor, the internet anonymiser, received more than $1.8m in funding from the US government in 2013, even while the NSA was reportedly trying to destroy the network.
According to the Tor Project’s latest annual financial statements, the organisation received $1,822,907 from the US government in 2013. The bulk of that came in the form of “pass-through” grants, money which ultimately comes from the US government distributed through some independent third-party.
Sorta Somewhat Related, Tinfoil Hat Edition: Back in January, Reuters reported that the NSA funneled $10 million to RSA, a computer security firm whose encryption tools are an industry standard. The Reuters report indicates that the funding helped ensure that a less secure encryption system was used as the default setting in an RSA “software tool called Bsafe that is used to enhance security in personal computers and many other products.”
Sverker Johansson could be the most prolific author you’ve never heard of.
Volunteering his time over the past seven years publishing to Wikipedia, the 53-year-old Swede can take credit for 2.7 million articles, or 8.5% of the entire collection, according to Wikimedia analytics, which measures the site’s traffic. His stats far outpace any other user, the group says.
He has been particularly prolific cataloging obscure animal species, including butterflies and beetles, and is proud of his work highlighting towns in the Philippines. About one-third of his entries are uploaded to the Swedish language version of Wikipedia, and the rest are composed in two versions of Filipino, one of which is his wife’s native tongue.
An administrator holding degrees in linguistics, civil engineering, economics and particle physics, he says he has long been interested in “the origin of things, oh, everything.”
It isn’t uncommon, however, for Wikipedia purists to complain about his method. That is because the bulk of his entries have been created by a computer software program—known as a bot. Critics say bots crowd out the creativity only humans can generate.
Mr. Johansson’s program scrubs databases and other digital sources for information, and then packages it into an article. On a good day, he says his “Lsjbot” creates up to 10,000 new entries.
That’s one way to go about it. Some Wikipedia editors aren’t happy it though.
For all those who have Q’d us about where to start with gear, here’s an excellent set of tools recommended by the Director of Digital Media at Columbia J-School.
My video students at Columbia Journalism School are trained on the Canon C100. It is a great camera, but the $5K+ price tag makes it impossible for most to purchase one for themselves. Also, that figure does not include microphones, tripods, and other accessories necessary to produce professional-quality video.
With some compromises in ergonomics and picture quality, the list of gear below should be an affordable alternative for any video student or recent grad. This gear will give you high-quality visuals, clean sound, and reliable stabilization. I hesitate to call this a starter kit, as you can shoot a feature documentary with this set up.
Camera: The conventional wisdom with video gear is to invest in lenses and peripherals. These items will last you years, while cameras get updated and replaced constantly. I still recommend DSLRs for video journalists starting out. They are cheap. Their sensors are big, the low-light performance is fantastic, and they double as great stills cameras (ironically, an often overlooked benefit). I have years of experience with Canon gear, so I recommend their products. But Sony, Panasonic, and others all offer up great solutions. Shop around. This is a great time to buy.
I recommend two entry-level DSLRs to my students. The Canon T5i w/ EF-S 18-55mm f/3.5-5.6 IS STM Lens and the Canon EOS Rebel SL1 w/ EF-S 18-55mm f/3.5-5.6 IS STM Lens. The T5i has a flip-out screen, but the SL1 is smaller. In terms of image quality, they are the same. My SL1 is so small that I can comfortably carry it with me everywhere I go.
If you can afford it, I recommend getting the Canon EF 24-105mm f/4L IS USM Lens. This is my go-to lens for all my documentary work. It is pricey, but it is a great investment. You will grow with this lens. If you do purchase the 24-105, be sure to get the Canon EOS Rebel T5i DSLR Camera (Body Only) or Canon EOS Rebel SL1 DSLR Camera (Body Only) to save some money.
Do not forget to buy some extra batteries for your shoots. You can go for the more expensive Canon option or save some money going with a third-party brand. And be sure to get protective filters for your lenses: the Tiffen 58mm UV Protector Filter for the kit lens or the Tiffen 77mm UV Protector Filter for the 24-105 lens.
Audio: The most important part of producing great video is getting great audio. Audio gear can be very expensive and there are many options on the market. But the gear below was specifically designed to work with DSLRs. This set up will transform your DSLR into a fully-functioning video camera:
- Tascam DR-60D to Camera Essentials Kit
- Rode VideoMic Pro Compact Shotgun Microphone
- Rode VXLR - Mono Mini-Jack to XLR Converter
Your mics go into the DR-60D and then that signal is fed into the camera. Or, when you really want to just go small and stealth, the Rode VideoMic Pro can plug directly into your DSLR (as pictured above). Also, the Tascam DR-60D can be used alone as a great field audio recorder.
My most expensive audio recommendation is the Sony ECM-77B - Lavalier Microphone. This is the microphone I use for all my interviews. It plugs directly into the DR-60D. There are much cheaper lav mics available, but IMHO, the low audio quality is not worth the savings.
Support: You need a good tripod and monopod to get steady shots. Tripods go from super cheap to insanely expensive. I recommend spending a little more now for gear that will last you years. I always shoot with the Manfrotto Fluid Monopod with 500 Series Head and Manfrotto MVH500AH Fluid Head & 755XB Tripod. They are not the cheapest options, but you will have them for years.
I hope this list helps.
They don’t tell you that a lot of programming skill is about developing a knack for asking the right questions on Google and knowing which code is best to copy-paste. And they don’t let you in on a big secret: that there is no mastery, there is no final level. The anxiety of feeling lost and stupid is not something you learn to conquer, but something you learn to live with.
