DMCA Review: Big Win For Right To Repair, Zero For Right To Tinker

October 26, 2018 by 35 Comments

This year’s Digital Millennium Copyright Act (DMCA) triennial review (PDF, legalese) contained some great news. Particularly, breaking encryption in a product in order to repair it has been deemed legal, and a previous exemption for reverse engineering 3D printer firmware to use the filament of your choice has been broadened. The infosec community got some clarification on penetration testing, and video game librarians and archivists came away with a big win on server software for online games.

Moreover, the process to renew a previous exemption has been streamlined — one used to be required to reapply from scratch every three years and now an exemption will stand unless circumstances have changed significantly. These changes, along with recent rulings by the Supreme Court are signs that some of the worst excesses of the DMCA’s anti-circumvention clause are being walked back, twenty years after being enacted. We have to applaud these developments.

However, the new right to repair clause seems to be restricted to restoring the device in question to its original specifications; if you’d like to hack a new feature into something that you own, you’re still out of luck. And while this review was generally favorable of opening up technology to enable fair use, they didn’t approve Bunnie Huang’s petition to allow decryption of the encryption method used over HDMI cables, so building your own HDMI devices that display encrypted streams is still out. And the changes to the 3D printer filament exemption is a reminder of the patchwork nature of this whole affair: it still only applies to 3D printer filament and not other devices that attempt to enforce the use of proprietary feedstock. Wait, what?

Finally, the Library of Congress only has authority to decide which acts of reverse engineering constitute defeating anti-circumvention measures. This review does not address the tools and information necessary to do so. “Manufacture and provision of — or trafficking in — products and services designed for the purposes of circumvention…” are covered elsewhere in the code. So while you are now allowed decrypt your John Deere software to fix your tractor, it’s not yet clear that designing and selling an ECU-unlocking tool, or even e-mailing someone the decryption key, is legal.

Could we hope for more? Sure! But making laws in a country as large as the US is a balancing act among many different interests, and the Library of Congress’s ruling is laudably clear about how they reached their decisions. The ruling itself is worth a read if you want to dive in, but be prepared to be overwhelmed in apparent minutiae. Or save yourself a little time and read on — we’ve got the highlights from a hacker’s perspective.

The Science Of Landing On An Asteroid

October 16, 2018 by 17 Comments

Exploiting the resources of the rock-strewn expanse of space between Mars and the outer planets has been the stuff of science fiction for ages. There’s gold in them ‘thar space rocks, or diamonds, or platinum, or something that makes them attractive targets for capitalists and scientists alike. But before actually extracting the riches of the asteroid belt, stuck here as we are at the bottom of a very deep gravity well that’s very expensive to climb out of, we have to answer a few questions. Like, how does one rendezvous with an asteroid? What’s involved with maneuvering near a comparatively tiny celestial body? And most importantly, how exactly does one land on an asteroid and do any useful work?

Back in June, a spacecraft launched by the Japanese Aerospace Exploration Agency (JAXA) finally caught up to an asteroid named Ryugu after having chased it for the better part of four years. The Hayabusa2 was equipped to answer all those questions and more, and as it settled in close to the asteroid with a small fleet of robotic rovers on board, it was about to make history. Here’s how they managed to not only land on an asteroid, but how the rovers move around on the surface, and how they’ll return samples of the asteroid to Earth for study.

Construction Cranes Versus Hurricanes

October 15, 2018 by 14 Comments

When engineers are designing buildings, bridges, or other large construction projects, a lot of thought is given to the environment. Some of these considerations might seem obvious, like designing a skyscraper in San Francisco to tolerate earthquakes, building a stadium in New York City to hold up not only its own weight but the weight of several feet of snow on the roof, or constructing bridges in any coastal area to be able to tolerate salt spray. Not everything is this straightforward, though. Not only do the structures themselves have to tolerate the environmental conditions they are in, but the equipment that is used to build them must tolerate these conditions as well, specifically the large cranes that are often semi-permanently attached to their construction sites.

Perhaps the most extreme example of this in recent memory was during Typhoon Manghut as it hit Hong Kong. There were several large construction cranes that didn’t fare too well with the high winds. At least one toppled as a result and catching the free-spinning of another on video is more than enough to make you gasp. Other videos of construction cranes surfaced from this typhoon showing some concerning, but surprisingly well-designed, emergency operation of the same type of crane.

International Space Station Is Racing The Clock After Soyuz Failure

October 11, 2018 by 120 Comments

Today’s failed Soyuz launch thankfully resulted in no casualties, but the fate of the International Space Station (ISS) is now in question.

Just two minutes after liftoff, the crew of the Soyuz MS-10 found themselves in a situation that every astronaut since the beginning of the manned space program has trained for, but very few have ever had to face: a failure during launch. Today the crew of two, Russian Aleksey Ovchinin and American Nick Hague, were forced to make a ballistic re-entry into the Earth’s atmosphere; a wild ride that put them through higher G forces than expected and dropped the vehicle approximately 430 km from the launch site in Baikonur. Both men walked away from the event unharmed, but while the ordeal is over for them, it’s just beginning for the crew of the ISS.

Until a full investigation can be completed by Roscosmos, Russia’s space agency, the Soyuz rocket is grounded. This is standard procedure, as they obviously don’t want to launch another rocket and risk encountering the same issue. But as the Soyuz is currently the only way we have to get humans into space, this means new crew can’t be sent to the ISS until Roscosmos is confident the issue has been identified and resolved.

Soyuz MS-11, which would have brought up three new crew members to relieve those already on the Station, was scheduled for liftoff on December 20th. While not yet officially confirmed, that mission is almost certainly not going to be launching as scheduled. Two months is simply not long enough to conduct an investigation into such a major event when human lives are on the line.

The failure of Soyuz MS-10 has started a domino effect which will deprive the ISS of the five crew members which were scheduled to be aboard by the end of 2018. To make matters worse, the three current crew members must return to Earth before the end of the year as well. NASA and Roscosmos will now need to make an unprecedented decision which could lead to abandoning the International Space Station; the first time it would be left unmanned since the Expedition 1 mission arrived in November 2000.

This Year’s Nobel Prizes Are Straight Out Of Science Fiction

October 10, 2018 by 22 Comments

In the 1966 science fiction movie Fantastic Voyage, medical personnel are shrunken to the size of microbes to enter a scientist’s body to perform brain surgery. Due to the work of this year’s winners of the Nobel Prize in Physics, laser tools now do work at this scale.

Arthur Ashkin won for his development of optical tweezers that use a laser to grip and manipulate objects as small a molecule. And Gérard Mourou and Donna Strickland won for coming up with a way to produce ultra-short laser pulses at a high-intensity, used now for performing millions of corrective laser eye surgeries every year.

Here is a look at these inventions, their inventors, and the applications which made them important enough to win a Nobel.

Google Discovers Google+ Servers Are Still Running

October 9, 2018 by 70 Comments

Google is pulling the plug on their social network, Google+. Users still have the better part of a year to say their goodbyes, but if the fledgling social network was a ghost town before, news of its imminent shutdown isn’t likely to liven the place up. A quick check of the site as of this writing reveals many users are already posting their farewell messages, and while there’s some rallying behind petitions to keep the lights on, the majority realize that once Google has fallen out of love with a project there’s little chance of a reprieve.

To say that this is a surprise would be disingenuous. We’d wager a lot of you already thought it was gone, honestly. It’s no secret that Google’s attempt at a “Facebook Killer” was anything but, and while there was a group of dedicated users to be sure, it never attained anywhere near the success of its competition.

According to a blog post from Google, the network’s anemic user base isn’t the only reason they’ve decided to wind down the service. A previously undisclosed security vulnerability also hastened its demise, a revelation which will particularly sting those who joined for the privacy-first design Google touted. While this fairly transparent postmortem allows us to answer what ended Google’s grand experiment in social networking, there’s still one questions left unanswered. Where are the soon to be orphaned Google+ users supposed to go?

Will Drones And Planes Be Treated As Equals By FAA?

October 8, 2018 by 87 Comments

Soon, perhaps even by the time you read this, the rules for flying remote-controlled aircraft in the United States will be very different. The Federal Aviation Authority (FAA) is pushing hard to repeal Section 336, which states that small remote-controlled aircraft as used for hobby and educational purposes aren’t under FAA jurisdiction. Despite assurances that the FAA will work towards implementing waivers for hobbyists, critics worry that in the worst case the repeal of Section 336 might mean that remote control pilots and their craft may be held to the same standards as their human-carrying counterparts.

Section 336 has already been used to shoot down the FAA’s ill-conceived attempt to get RC pilots to register themselves and their craft, so it’s little surprise they’re eager to get rid of it. But they aren’t alone. The Commercial Drone Alliance, a non-profit association dedicated to supporting enterprise use of Unmanned Aerial Systems (UAS), expressed their support for repealing Section 336 in a June press release:

Basic ‘rules of the road’ are needed to manage all this new air traffic. That is why the Commercial Drone Alliance is today calling on Congress to repeal Section 336 of the FAA Modernization and Reform Act of 2012, and include new language in the 2018 FAA Reauthorization Act to enable the FAA to regulate UAS and the National Airspace in a common sense way.

With both the industry and the FAA both pushing lawmakers to revamp the rules governing small remote-controlled aircraft, things aren’t looking good for the hobbyists who operate them. It seems likely those among us with a penchant for airborne hacking will be forced to fall in line. But what happens then?
