Comment Re:Integral layer of the Trusted-Computing/DRM sta (Score 1) 34

Every time people hear what it actually involves is outrage and opposition, at least all the way back to when Intel first announced that they wanted to hardcode identity numbers inside CPUs in 1999. But the corporations involved have been relentless, and have sunk countless billions of dollars steadily forcing it forwards, and building front organizations to obfuscate and whitewash it.

With Windows 11, Microsoft was finally able to FORCE Trusted computing hardware into every new computer. Not just every new Windows computer, but every computer.

Every new Intel PC CPU has built in Trusted Computing enforcement hardware. Every new AMD PC CPU has built in Trusted Computing enforcement hardware. Every new ARM PC CPU has built in Trusted Computing enforcement hardware. The only processor lines that DON'T have it are the microcontrollers.

There are some unlocked smartphones available, but as far as I can determine it's literally impossible to buy a smartphone that doesn't have hardware trusted computing built in.

I specified that enforcing Trusted Computing at the internet access level is still a long term goal, they couldn't get away with it today. However they are well on the way to success. Virtually all new hardware supporting trusted computing, all the front groups rolling out standards and systems, and as it gets incorporated into things everyone is going to increasingly running into situations where they get locked out of stuff if they're not Trusted Computing compliant. Streaming already restricts you to the worst quality if you're not compliant, and it's only going to get worse as pre-Win11 computers fade out and as more things require it.

I'd hardly call exact date of birth "low information content".

And yes this does reveal exact date of birth, regardless of the bullshit obfuscation that it supposedly only reports age range. The server simply tracks the reported result every time the user connects, and on some specific day the result CHANGES to announce their date of birth.

Comment Integral layer of the Trusted-Computing/DRM stack (Score 1) 34

This is based on SLSA (Supply-chain Levels for Software Artifacts), brought to you by the same fuckers making Trusted Computing and the TMP (Trusted Platform Module). It's part of the same shitstack to prohibit you from altering your software and to lock you out of your own files, and to send spy reports out over the internet so you can be cut off if you "fail" the Trusted Computing check.

The software can use a TPM's (Trusted Platform Module) Sealing function to encrypt your data such that it's impossible to access your own data if the software is modified. It can then pass control over that data only to software updates that carry a signed security certificate from Broadcom (or any other company using this system).

It is no longer open source, your system no longer works as you can no longer access your Sealed data if you change so much as a single letter of the code. Even recompile unaltered code won't work, unless you magically manage to get your build environment absolutely identical to the company's build environment and get byte-for-byte output. Even that may be impossible with the newer levels of non-deterministic compiler optimizations.

Also, with TMP's Remote Attestation feature can be used to transmit your machine's software configuration over the internet, so that you can be cut off if your system doesn't match Broadcom (or other company's) cryptographically signed certificate.

And then of course there's Network Access Control (NAC) / Trusted Network Connect (TNC). In the long term, the goal is for ISPs to use NAC/TNC to interrogate your computer for Trusted Computing compliance, and deny you any internet access whatsoever if your machine isn't compliant. Software with this sort of "security" certificate would pass inspection, while any attempt to alter the code would be detected as "tampering". You then get "quarantined". What "quarantine" means is that you are denied internet access - with the exception that you do get very restricted access which can only be used to download the approved software to "fix" your computer into Trusted Computing compliance.

Ask Slashdot: What are the Costs of Switching Between Windows, MacOS, and Chrome? 66

UI changes, lost productivity, untransferrable knowledge... Long-time Slashdot reader theodp notes the folly of switching to an unfamiliar new environment to be "more productive"... Champions of the switch often insist workers will be able to hit the ground running and get the same or even more work done from the get-go in the new unfamiliar environment because it's 'more productive', a conclusion often shaped by conventional wisdom or their 'gut' feeling. Decision makers may also mistake their own 'light-user experience' for universal experience and believe all platforms are fungible.

And while it's one thing for a business to delay their delivery dates and increase costs of by introducing a switch in computing environments that's of unquantified and possibly dubious value, how about when a switch in computing environments is made that affects schoolchildren's ability to learn for a period of time?

While a MacBook Neo is indeed cute, what might be the possible consequences of a decision to move 25,000 students off Windows and onto MacBook Neos...? Or even the impact on a single kid who moves from a MacBook school to a Windows or Chrome school (or whose home computing environment isn't aligned with their school). Or students whose teachers decide learning in their classrooms should now additionally require an understanding of the Minecraft computing platform/UI (used in over 40,000 school systems.). Learning Management Systems and now various AI Edtech tools used by schoolkids are also subject to change.

"Even if students and schools eventually benefit from a new platform, one wonders how much learning is lost during the switch," theodp asks, "and what the financial and educational ROI and payback period look like."

Non-Invasive Stimulation of the Brain Ended Opioid Addiction, Cigarette Craving (jpost.com) 37

The Jerusalem Post reports that doctors at Haifa's Rambam Health Care Campus "have successfully treated their first Israeli opioid addiction patient using an experimental noninvasive brain technology, easing him through withdrawal in just 20 minutes..." [T]he team of specialists at the Haifa medical center intervened in the electrical activity of an area of the patient's brain called the nucleus accumbens, the core of the brain system responsible for feelings of satisfaction, pleasure, and reward. The treatment, based on technology from the Israeli company Insightec, is similar to the one used to treat symptoms of essential tremor and Parkinsonian tremor, under MRI control. In this case, the treatment was carried out with the help of a new technology that performs noninvasive neuromodulation, without heating or burning tissue, and allows stimulation in the same area of the brain to increase or suppress activity...

"Tests carried out a week later produced negative results for opioids and other substances," [said Dr. Lior Lev-Tov, director of the functional neurosurgery unit in Rambam's neurosurgery division and the one leading the new study at the medical center.] "The patient himself reported a craving score of zero out of 10 for using the drug, and even another side effect, a drastic drop in the desire for cigarettes, from three packs a day to just a few cigarettes, and with no urge to use alcohol. In other words, in a treatment that lasted about 20 minutes net, our patient was completely freed from an extreme dependence that had accompanied him every day for years. This is nothing less than a medical and therapeutic revolution."

Dr. Lev-Tov added that "This experience opens doors for us to treat a wide range of very serious illnesses such as PTSD, OCD, eating disorders, other addictions, severe depression, severe pain disorders, and I hope we will also be able to reach cognitive areas and treat attention deficit disorders, Alzheimer's, Parkinson's, and more."

Blue Origin Rocket Exploded Thursday Night During Hot-Fire Test (cbsnews.com) 73

Spaceflight Now shared their video of the explosion, which the Orlando Sentinel describes as showing Blue Origin's rocket "become engulfed in flames. The fireball expands out and covers the entire launch pad as the fuselage of the rocket can be seen crumbling into the flames."

Blue Origin founder Jeff Bezos said on X.com "It's too early to know the root cause but we're already working to find it. Very rough day, but we'll rebuild whatever needs rebuilding and get back to flying. It's worth it." (SpaceX founder Elon Musk posted "Sorry to see this, I hope you recover quickly.")

It's unclear how this will impact future launches. "The rocket was destroyed," reports CBS News, "and as the smoke cleared, there was no sign of the erector-gantry used to move the New Glenn from its hangar to the pad and to raise it from horizontal to vertical. Likewise, one of two tall lightning towers was no longer visible." It was the first such on-pad explosion at the Cape since a SpaceX Falcon 9 rocket blew up on nearby pad 40 on Sept. 1, 2016... Blue Origin only has one New Glenn pad, the one that was damaged in the Thursday test. The New Glenn, which has launched three times, is a heavy lift rocket designed to compete head-to-head with SpaceX Falcon 9 and Falcon Heavy rockets. During New Glenn's most recent flight in April, an upper stage malfunction prevented a commercial internet satellite from reaching its planned orbit...

The New Glenn destroyed Thursday was to send 48 Leo internet satellites owned by Amazon into space [which were not on board for the hot-fire test]

Blue Origin posted on X.com that "Debris from our recent hotfire anomaly may wash ashore in the coming days/weeks. If you encounter any debris, do not touch or approach it for your safety."

"Spaceflight is unforgiving, and developing new heavy-lift launch capability is extraordinarily difficult..." NASA Administrator Jared Isaacman posted on X.com. "âWe will provide information on any impacts to the Artemis and Moon Base programs as it becomes available."

Scientists Found a Way To Cool Quantum Computers Using Noise (sciencedaily.com) 7

Slashdot reader alternative_right writes: Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Google, Microsoft, Apple, Facebook, Amazon, or another one of the big software development companies could easily fork ffmpeg itself, fix the open CVEs, provide their own (likely incompatible) features, and become the new standard - leaving the original developers out in the cold. Google did this with Blink (forked from WebKit, which itself was forked from KHTML). They took a fork of a KDE backed project, put it into what is now the #1 browser in the world, allowed Microsoft, Opera, and others to then use it in their own browsers — and now Google owns the entire narrative and development direction for the engine (in parallel to, and controlled to a lesser extent by Apple which maintains WebKit). The original KHTML developers really couldn’t keep up, and stopped maintaining KHTML back in 2016 (with full deprecation in 2023).

That is the risk for the original developers here. You’re right in that there isn’t really anything out there that can do what ffmpeg does — but if the developers don’t keep up on CVEs then organizations are going to look for new maintainers — and a year or two from now everyone will be using the Google/Microsoft/Apple/Facebook renamed version of ffmpeg instead.

That’s the shitty truth of how these things work. We’ve seen these same actors do it before.

Look — I’m a developer. I get it. I’m personally all for having organizations do more to support the OSS they rely on. But the people in the C-suite are more worried about organizational reputation and losing money to lawsuits. If a piece of software they rely on has a known critical CVE that allows for remote code execution and someone breaks in and steals customer data — that software either needs to be fixed, or it needs to be scrapped. Those are the choices. Our customers in the EU are allowed to request SBOMs of everything we use and pass it through their own security validation software — and if they find sev critical CVEs in software we’re using there is going to be hell to pay. And the people in the C-suite can’t abide that level of risk.

Most software development companies (outside some of the biggest ones) don’t really have the kind of expertise in house to supply patches to something as complex as ffmpeg. But a company like Google has the staff with sufficient experience in this area that they could fork the project, fix the issues, and redistribute it as their own solution to the problem — and now Google is driving ffmpeg development. Organizations that need a security-guaranteed version will simply switch to Google’s version, which will likely slowly become incompatible with the original. They’ve done it before — Chrome was Google’s fork of WebKit, huge swaths of users flocked to Chrome, and now Google has over the years made enough changes that their patches often aren’t compatible with WebKit (and, of course, WebKit itself did similar when they forked KHTML).

Now forking like this is great for the community, but it can be tough on individual developers who see their work co-opted and then sidelined by massive corporations. And that’s really why the ffmpeg developers need to be very careful about ignoring CVEs like this. They do so at their own peril, as anyone can fork their code, fix the issues, and slowly make it incompatible with the original. And a big enough organization can ensure they’re fork becomes the new standard, leaving the original developers out in the cold.

Eventually whoever has most to lose is bound to step up and help.

That, or your project gets sidelined. Which is where the danger lies.

I work for a big multinational software company that uses a lot of Open Source Software. We have a security office that audits all of our products several times a year. If any piece of our stack shows any open CVEs we have a fixed amount of time to fix the issue, with the amount of time varying from a few days (for CRITICAL severity issues) to roughly half a year for the lowest severity issues. A lack of a fix for a published CVE isn’t an excuse for not fixing the issue on our end — the software still has a security flaw in it, and the organization is so incredible security averse (thanks in part to having contacts in the defence industry) that they don’t want to risk expensive lawsuits and the loss of reputation if a vulnerability is exploited.

A lot of bigger organizations now work this way. We’ve all seen what has happened to organizations that have had significantly security breaches, and it’s not pretty. Our customers are big corporations and government entities — and if they even sniff a risk there are going to be problems. So if there is an unpatched exploit, we’re expected to either switch to something comparable, or DIY a solution (either replacing the library in question, or potentially patching it ourselves).

If ffmpeg allows known and published vulnerabilities to languish, the risk here is that organizations that use their code will simply stop using it and will look for other solutions. That’s a tough pill for an Open Source Software developer to swallow, especially when they make it as big and important as ffmpeg. You might wind up in a situation where an entity like Google forks your code and takes ownership, and eventually gets everyone to migrate to using their version instead (like what they did with WebKit to Chrome), leaving you sidelines. Or maybe someone else jumps in with a compatible solution that works well enough for enough users that they switch to that instead.

Now in an ideal world, the Google’s of this world would not only submit a CVE but would also submit a patch. Having been an OSS developer myself I’ve always encouraged my staff if they find a bug in a piece of software we use to file a bug report and ideally a patch if they know how to patch the issue correctly — but I know that is hardly universal within our organization, and probably even less so elsewhere.

TL;DR: a lot of OSS success relies on having lots of users, or at least some big and important users. But you risk losing those if you leave CVE’s open for too long, as company policies may require scrapping software with unfixed CVEs. That loss of users and reputation is dangerous for an OSS project — it’s how projects get supplanted, either by a fork or by a new (and similar) project.

Manufacturer Remotely Bricks Smart Vacuum After Its Owner Blocked It From Collecting Data (tomshardware.com) 123

"An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device," writes Tom's Hardware.

"That's when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn't consented to." The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after... He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again... [H]e decided to disassemble the thing to determine what killed it and to see if he could get it working again...

[He discovered] a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware. From this, he looked at its software and operating system, and that's where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data.

First of all, it's Android Debug Bridge, which gives him full root access to the vacuum, wasn't protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home. This isn't unusual, by far. After all, it's a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer's server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers.

Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

New Large Coral Reef Discovered Off Naples Containing Rare Ancient Corals (independent.co.uk) 13

Off the southwest cost of Italy, a remotely operated submarine made "a significant and rare discovery," reports the Independent — a vast white coral reef that was 80 metres tall (262 feet) and 2 metres wide (6.56 feet) "containing important species and fossil traces." Often dubbed the "rainforests of the sea", coral reefs are of immense scientific interest due to their status as some of the planet's richest marine ecosystems, harbouring millions of species. They play a crucial role in sustaining marine life but are currently under considerable threat...

hese impressive formations are composed of deep-water hard corals, commonly referred to as "white corals" because of their lack of colour, specifically identified as Lophelia pertusa and Madrepora oculata species. The reef also contains black corals, solitary corals, sponges, and other ecologically important species, as well as fossil traces of oysters and ancient corals, the Italian Research Council said. It called them "true geological testimonies of a distant past."

Mission leader Giorgio Castellan said the finding was "exceptional for Italian seas: bioconstructions of this kind, and of such magnitude, had never been observed in the Dohrn Canyon, and are rarely seen elsewhere in our Mediterranean". The discovery will help scientists understand the ecological role of deep coral habitats and their distribution, especially in the context of conservation and restoration efforts, he added.

The undersea research was funded by the EU.

If you read the article carefully, they are talking about lenses THINNER than a hair. I see several of the posts here thinking the width/radius of the lenses is this small, a reasonable mistake given the way this was written. Having a radius that small would severely reduce their light gathering ability, requiring very bright light or very dim images or very long exposure times.
