The DHS Issues Medical Advisory for Medtronic Cardiac Devices

The Department of Homeland Security (DHS) has issued a cybersecurity warning that documents vulnerabilities in the Medtronic Conexus Radio Frequency Telemetry Protocol. Medtronic makes cardio-defibrillators that are planted into a patient's chest and can be read and programmed by trained medical personnel. This allows the devices to communicate with home monitoring devices and Carelink programmers found at doctor's offices. These vulnerabilities require a low level of skill to exploit as the proprietary Conexus telemetry protocol utilized within this ecosystem does not implement authentication or authorization. An attacker can inject, replay, modify, and/or intercept data within the telemetry communication. This communication protocol provides the ability to read and write memory values to affected implanted cardiac devices; therefore, an attacker could exploit this communication protocol to change memory in the implanted cardiac device. Because the devices also lack encryption, attackers can listen to communications, including the transmission of sensitive data. Medtronics is working on developing updates to fix the vulnerabilities.

"It is possible with this attack to cause harm to a patient, either by erasing the firmware that is giving necessary therapy to the patient's heart, or by directly invoking shock related commands on the defibrillator," he said. "Since this protocol is unauthenticated, the ICD cannot discern if communications its receiving are coming from a trusted Medtronic device, or an attacker." A successful attacker could erase or reprogram the defibrillator's firmware, and run any command on the device.

AMD Confirms Stadia Will Run on Intel CPUs

As one of the world's most pervasive cloud service providers, Google is in a better position to launch a successful game streaming platform than almost anyone. The hardware they choose to use for the launch of their "Stadia" streaming service will undoubtedly influence future game streaming efforts, hence AMD's stock price shot through the roof when Google announced they were using AMD GPUs. However, PCGamesN writer Dave James noticed that Google was conspicuously silent when it came to Stadia's CPUs. They were happy to share clock speeds, cache numbers and the fact that they're using "custom" x86 chips, but they refused to confirm the vendor of the platform's CPU. Eventually, AMD reached out and said that "the Stadia platform is using custom AMD Radeon datacentre GPUs, not AMD CPUs." Barring any surprise announcements from VIA, that more or less confirms that Stadia will run on some sort of Intel CPU platform, but just why Google refused to mention Chipzilla by name remains a mystery. The author suggested that Intel might not want to associate themself with what might be a "doomed" venture. Maybe Google plans to switch to EPYC CPUs or an unannounced Intel server platform sometime in the future, or maybe they just don't think it's particularly relevant. Whatever the reason may be, I also find the omission to be curious, and look forward to seeing what happens with Stadia's hardware in the future.

A switch to AMD's EPYC processors has been mooted as a potential future step for Stadia, and Google's Phil Harrison told us himself that "we're just talking about Gen 1 at the moment, but there will be iterations on that technology over time," so there is some potential for a changing of the processor guard either before or after launch. Whatever the truth of the matter is I still find it beyond strange that no-one involved is talking about the Intel CPUs being used for Google Stadia, even if they're not necessarily doing anything that special with regards the innovative streaming service. Certainly the multi-GPU features on offer with the Radeon graphics cards warranted mention, but just a note on the specs slide alone could have still done good things for Intel.

Ransomware Encourages Victims to Subscribe to PewDiePie

PewDiePie's battle with Bollywood star T-Series has pushed some of his more enthusiastic fans to extremes. A group of hackers used printers to promote their favorite YouTuber last year, and more recently, they hacked their way into Smart TVs, Chromecasts, and Google Home devices. Now, recent reports claim that new strains of ransomware are encouraging users to subscribe to PewDiePie. The "PewDiePie ransomware" released last year didn't even bother to save encryption keys, which means whatever user data it targeted was gone for good, while a new strain that popped up this January runs in Java to make detection more difficult. However, instead of asking for a ransom, the later program simply offers a link to PewDiePie's subscription page. It claims that public keys will be released if PewDiePie hits 100 million subscribers before T-Series, while the user's data will never see the light of day again if T-Series hits that mark first. ZDNet says the software was "put together as a joke," but still managed to infect a few users, and that the code is now publicly available on GitHub. Thanks to AceGoober for the tip, and check out a demonstration of the ransomware below:

Both ransomware strains show the level of idiocy the competition for YouTube's top spot has reached. While T-Series fans have remained mostly quiet most of this time, a portion of PewDiePie's fans appears to have lost their minds and engaged in media stunts bordering on criminal behavior... The message itself has become a meme, and not in a good way.

Google Fined $1.7 Billion Over Monopolistic Practices

The European commission has reportedly slapped Google with a 1.49 billion Euro (or $1.69 billion USD) fine for "abusing its monopoly in online advertising." More specifically, the report alleges that Google prevented companies that using its search service from running any third party adverts, and the commission claims that "Google's rivals were not able to compete on the merits, either because there was an outright prohibition for them to appear on publisher websites or because Google reserved for itself by far the most valuable commercial space on those websites, while at the same time controlling how rival search adverts could appear." Google apparently changed these practices in 2016, but it took some time for the repercussions to catch up with them.

Margrethe Vestager, the EU's competition commissioner, said: "Google has cemented its dominance in online search adverts and shielded itself from competitive pressure by imposing anti-competitive contractual restrictions on third-party websites. This is illegal under EU antitrust rules. The misconduct lasted over 10 years and denied other companies the possibility to compete on the merits and to innovate - and consumers the benefits of competition."

Samsung Introduces Next Generation HBM2E

At NVIDIA's GPU Technology Conference, Samsung unveiled an even faster version of their HBM2 memory. A stack of "Flashbolt," as they call it, can deliver up to 410 GBps of bandwidth, which they claim is 33% faster than previous offerings, and a single package can hold up to 16GB of memory. Samsung says the new memory is aimed at "supercomputers, graphics systems, and artificial intelligence (AI)" applications, though they didn't mention just what GPUs or accelerators will make use of it in the near future.

"Flashbolt's industry-leading performance will enable enhanced solutions for next-generation data centers, artificial intelligence, machine learning, and graphics applications," said Jinman Han, senior vice president of Memory Product Planning and Application Engineering Team at Samsung Electronics. "We will continue to expand our premium DRAM offering, and improve our 'high-performance, high capacity, and low power' memory segment to meet market demand."

Digital Foundry Analyzes Google's Stadia Platform

Following Google's "Stadia" game streaming service announcement yesterday, Digital Foundry decided to take a closer look at the hardware behind the platform. Google says they use a "Custom 2.7GHz hyper-threaded x86 CPU with AVX2 SIMD and 9.5MB L2+L3 cache," and while they didn't mention the vendor, DF notes that they haven't seen such a configuration in any of AMD's currently shipping server CPUs, and that it should significantly outpace anything found in a modern console. Meanwhile, the GPU largely resembles a Vega 56 card with 16GB of HBM2, and the games are reportedly loaded from an SSD. Through their own testing, DF came away impressed with the platform's consistent frame pacing, and in some cases, total latency is on par with locally-run games on a console or PC.

Google has also demonstrated scalability on the graphics side, with a demonstration of three of the AMD GPUs running in concert. Its stated aim is to remove as many of the limiting factors impacting game-makers as possible, and with that in mind, the option is there for developers to scale projects across multiple cloud units: "The way that we describe what we are is a new generation because it's purpose-built for the 21st century," says Google's Phil Harrison. "It does not have any of the hallmarks of a legacy system. It is not a discrete device in the cloud. It is an elastic compute in the cloud and that allows developers to use an unprecedented amount of compute in support of their games, both on CPU and GPU, but also particularly around multiplayer."

Google Partners with AMD for Google Stadia Game Streaming Service

Google has selected AMD as its partner for the Google Stadia game streaming service. Google will use high-performance, custom AMD Radeon datacenter GPUs for its Vulkan and Linux-based Google Stadia. AMD noted how its commitment to open-source AMD Linux drivers would allow Google and its development partners to inspect the code and understand exactly how the driver works, enabling them to better optimize their applications to interface with AMD Radeon GPUs. AMD supplies other tools such as the AMD Radeon GPU Profiler (RGP) that allows developers to identify timing issues that might lead to optimizations. The Google Stadia service will feature game streams with resolutions up to 4K HDR 60 FPS. Google announced a 2019 launch time for the game streaming service.

Streaming graphics-rich games to millions of users on demand and from the cloud requires ultra high-performance processing capabilities to minimize latency and maximize game performance. It also requires advanced technologies to tackle unique datacenter challenges, including security, manageability, and scalability. The AMD graphics architecture supports a wide range of today's gaming platforms -- from PCs to major game consoles -- enabling developers to optimize their games for a single GPU architecture and extend these benefits across multiple platforms which now include large-scale cloud gaming platforms.

MSI Expected to Overtake Samsung in the Curved Monitor Market

A recent report from Digitimes claims that MSI could soon steal the title of "world's largest supplier of curved gaming monitors" from Samsung in 2019. While flat monitors have dominated "gaming monitor" sales in the past, MSI claims that curved monitors accounted for about 60% of all gaming monitor shipments in 2018, and could rise to 66.7% in 2019. The gaming hardware market is still growing, even as the PC market continues to shrink as a whole, so its not surprising to see the big manufacturers increase their focus on their enthusiast and "gaming" lineups.

The company's motherboard business is currently facing issues including CPU shortages and decreasing demand. Despite Intel having already promised to ease the tight supply by the end of the second quarter, MSI still expects overall motherboard shipments to shrink by over 10% in 2019. MSI shipped around six million motherboards in 2018 and is expected to maintain a similar volume in 2019. Meanwhile, MSI is expected to finish digesting its graphics card inventory in the second quarter and begin promoting Nvidia's new cards to help increase its sales. MSI is expected to deliver around four million graphics cards in 2019, about the same level as in the past couple of years.

All Myspace Data Before 2016 is Gone

Thanks to a "faulty server migration," MySpace has lost all data uploaded to the site before 2016. MySpace users started noticing the problem over a year ago, but tech support staff only recently started acknowledging that users' data may never come back. The Guardian claims "50m tracks from 14 million artists have been lost," and according to one of their articles from last year, the site still has many dedicated users.

Some have questioned how the embattled company, which was purchased by Time Inc in 2016, could make such a blunder. "I'm deeply sceptical this was an accident," wrote the web expert Andy Baio. "Flagrant incompetence may be bad PR, but it still sounds better than, 'We can't be bothered with the effort and cost of migrating and hosting 50m old MP3s.'" Myspace initially claimed the deletion was a temporary error, with customer support staff telling one user: "I have been informed the issue will be fixed." But by July last year it was publicly acknowledging that no such fix was forthcoming.

Real-Time Ray Tracing Support Comes to GeForce GTX GPUs and Game Engines

NVIDIA has announced that real-time ray tracing support is coming to GeForce GTX GPUs. This driver is scheduled to launch in April. GeForce GTX GPUs will execute ray traced effects on shader cores and support is extended to both Microsoft DXR and Vulkan APIs. NVIDIA reminds consumers that its GeForce RTX lineup of cards has dedicated ray tracing cores built directly into the GPU which deliver the ultimate ray tracing experience. GeForce RTX GPUs provide up to 2-3x faster ray tracing performance with a more visually immersive gaming environment than GPUs without dedicated ray tracing cores. NVIDIA GameWorks RTX is a comprehensive set of tools and rendering techniques that help game developers add ray tracing to games. Unreal Engine and Unity have announced that integrated real-time ray tracing support is being built into their engines.

Real-time ray tracing support from other first-party AAA game engines includes DICE/EA's Frostbite Engine, Remedy Entertainment's Northlight Engine and engines from Crystal Dynamics, Kingsoft, Netease and others. Quake II RTX -- uses ray tracing for all of the lighting in the game in a unified lighting algorithm called path tracing. The classic Quake II game was modified in the open source community to support ray tracing and NVIDIA's engineering team further enhanced it with improved graphics and physics. Quake II RTX is the first ray-traced game using NVIDIA VKRay, a Vulkan extension that allows any developer using Vulkan to add ray-traced effects to their games.
