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.

Microsoft Patent Describes a Persistence of Vision Augmented Reality Display

Microsoft has filed a patent for a new type of mixed-reality head-mounted display (HMD) called a Persistence of Vision Augmented Reality Display. The display uses movable screens to simulate a 360 degree field of view. These screens can rotate back and forth, spin around a user's head, or spin in front of the user's eyes. The device isn't guaranteed to ever see the light of day, but hopefully some of the ideas make it into other products.

Microsoft's patent FIG. 4A below illustrates a movement based display device with a movable member configured to rotate about a user's head; FIG. 4B illustrates a movement based display device with a movable member configured to reciprocate in front of user's eyes; FIG. 4C illustrates a movement based display device with movable members configured to spin in front of the user's eyes

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.

Sound BlasterX G6 Review

Audio Science Review has tested the Sound BlasterX G6 and found it to be surprisingly good for a budget device in a feature-filled package. During DAC testing it was discovered that the device's SINAD would rocket up to 112 dB if the level was dialed down by 2 dBFS (digitally.) Linearity was spot on but intermodulation distortion was a concern. Amirm discovered that dialing down the device by 2dBFS fixed the issue. He speculated that "The G6 is USB powered and likely doesn't have enough capacitance in its DC input to ride out the lasting peaks at low frequencies." The headphone amplifier measured great, and the output was decent but "there is no sensation of infinite power and you would be operating near or at max volume" when using the amp with a pair of Sennheiser HD-650 headphones. The last issue that irritated him was the lack of a properly working ASIO driver on Creative's website. He really liked the Sound BlasterX G6 and the review is full of charts and measurements conducted with a $28,300 Audio Precision APx555.

ADC Audio Measurements I was pleased that feeding the G6 2 volt, resulted in 0 dBFS showing no overflow. Performance though is not all that great with SINAD in the high 70s. We have lots of distortion components together with mains leakage. Compared to high-end products, we are short some 40 dB! Definitely not splitting hairs here.

Intel Previews Processors and Graphics Software at GDC 2019

At their GDC 2019 conference, Intel confirmed that they'll launch 9th generation mobile processors in the 2nd quarter of 2019. While 9th generation H-series and Y-series "Ice Lake" parts recently showed up on the EEC website, Intel told PC World that these parts are based on 14nm Coffee Lake Silicon. The company also mentioned that one of their goals with his release is "longer battery life" for gamers and more casual users alike, and they're promoting their Wi-Fi 6 capable AX200 chip and 3D XPoint memory with the new chips Meanwhile, Intel also showed off a new software suite for their modern IGPs and (presumably) their future GPUs. The "Intel Graphics Command Center" is essentially their answer to Nvidia's GeForce Experience and AMD's Game Advisor, as it automatically scans your PC for supported games and applies the optimal settings for your current hardware. An "early access" version of the control panel is available on the Microsoft Store, and oddly enough, it says it was "released" on 11/26/2018. Unlike other app stores, the Microsoft Store doesn't log updates or list old changes, so it was presumably in some kind of closed alpha before being officially launched today.

We asked, you answered. You're tired of our 'old, boring, corporate-looking' Graphics Control Panel. We were too and we designed a completely new one from the ground up! We're incorporating the changes you - the gamers, home theater enthusiasts, professionals, and everyday tinkerers requested. Using a phased approach, we're rolling out something we're proud to share with you: introducing the Intel Graphics Command Center.

Microsoft Criticizes FCC Broadband Report

According to a recently spotted FCC report, Microsoft thinks that the government is a little generous when it comes to their analysis of broadband availability. Based on their own analysis, some areas that supposedly have access to speeds of over 25 Mbps really don't have much access at all, and they suggest that the FCC should draw on a "broader array of data" in the future. Microsoft told MediaPost "This draft report simply doesn't reflect the state of things on the ground," and that "The agency is badly in need of better data and a more honest assessment of the state of broadband deployment."

"In some areas the Commission's broadband availability data suggests that Internet service providers ... have reported significant broadband availability (25 Mbps down/3 Mbps up) while Microsoft's usage data indicates that only a small percentage of consumers actually access the Internet at broadband speeds in those areas..." Microsoft weighed in with its concerns several days after advocacy group Free Press said the draft report was partially based on faulty data provided by the internet service provider BarrierFree. That company erroneously reported in a December 2017 filing that it offered fiber-to-the-home and fixed wireless service at speeds of nearly 1 GB to Census blocks containing almost 62 million people, according to Free Press. The incorrect information resulted in "a massive over-statement of the change in broadband deployment at the national level during 2017," Free Press told the FCC.

Microsoft Announces Variable Rate Shading Support for DX12

Variable Rate Shading (VRS) is a powerful new API that gives the developers the ability to use GPUs more intelligently. Shaders are used to calculate the color of each pixel in a screen. Shading rate refers to the resolution at which these shaders are called (which is different from the overall screen resolution). A higher shading rate means better visual fidelity at the cost of using more GPU power. All pixels in a frame are affected by the game's shading rate. VSR allows developers to choose which areas of the frame are more important and increase the visual fidelity, or set parts of the frame to have lower fidelity and gain extra performance. Lowering the fidelity of parts of the scene can help low spec machines to run faster. There are two tiers of support for VRS. First of all the VRS API lets developers set the shading rate in 3 different ways: per draw, within a draw by using a screenspace image, or within a draw, per primitive. The hardware that can support per-draw VRS hardware are Tier 1. There's also a Tier 2, the hardware that can support both per-draw and within-draw variable rate shading. VRS support exists today on in-market NVIDIA hardware and on upcoming Intel hardware. AMD is rumored to be working on support for the feature.

For example, foveated rendering, rendering the most detail in the area where the user is paying attention, and gradually decreasing the shading rate outside this area to save on performance. In a first-person shooter, the user is likely paying most attention to their crosshairs, and not much attention to the far edges of the screen, making FPS games an ideal candidate for this technique. Another use case for a screenspace image is using an edge detection filter to determine the areas that need a higher shading rate, since edges are where aliasing happens. Once the locations of the edges are known, a developer can set the screenspace image based on that, shading the areas where the edges are with high detail, and reducing the shading rate in other areas of the screen.

A Reminder from AMD: Our Processors Aren't Affected by New "SPOILER" Vulnerability

AMD has published a support article confirming its chips should be immune to "SPOILER," a new CPU vulnerability outlined by computer scientists at Worcester Polytechnic Institute and the University of Lubeck. As explained in their paper, SPOILER takes advantage of "a weakness in the address speculation of Intel’s proprietary implementation of the memory subsystem." This makes it easier for memory attacks such as "Rowhammer" to be carried out, but evidently, only Intel users need worry.

We are aware of the report of a new security exploit called SPOILER which can gain access to partial address information during load operations. We believe that our products are not susceptible to this issue because of our unique processor architecture. The SPOILER exploit can gain access to partial address information above address bit 11 during load operations. We believe that our products are not susceptible to this issue because AMD processors do not use partial address matches above address bit 11 when resolving load conflicts.
