Samsung Begins Mass Production of World’s Fastest DRAM

MojoKid writes: Late last year marked the introduction of High Bandwidth Memory (HBM) DRAM courtesy of AMD’s Fury family of graphics cards, each of which sports 4GB of HBM. HBM allows these new AMD GPUs to tout an impressive 512GB/sec of memory bandwidth, but it’s also just the first iteration of the new memory technology. Samsung has just announced that it has begun mass production of HBM2. Samsung’s 4GB HBM2 package is built on a 20 nanometer process. Each package contains four 8-gigabit core dies built on top of a buffer die. Each 4GB HMB2 package is capable of delivering 256GB/sec of bandwidth, which is twice that of first generation HBM DRAM. In the example of NVIDIA’s next gen GPU technology, code named Pascal, the new GPU will utilize HBM2 for its frame buffer memory. High-end consumer-grade Pascal boards will ship with 16GB of HBM2 memory (in four, 4GB packages), offering effective memory bandwidth of 1TB/sec (256GB/sec from each HMB2 package). Samsung is also reportedly readying 8GB HBM2 memory packages this year. Read more of this story at Slashdot.

New Linux Trojan Can Spy on Users by Taking Screenshots and Recording Audio

An anonymous reader writes: Dr.Web, a Russian antivirus maker, has detected a new threat against Linux users: the Linux.Ekoms.1 trojan. It includes functionality that allows it to take screenshots and record audio. While the screenshot activity is working just fine, Dr.Web says the trojan’s audio recording feature has not been turned on, despite being included in the malware’s source code. “All information transmitted between the server and Linux.Ekoms.1 is encrypted. The encryption is initially performed using the public key; and the decryption is executed by implementing the RSA_public_decrypt function to the received data. The Trojan exchanges data with the server using AbNetworkMessage.” Read more of this story at Slashdot.

Serious Linux Kernel Vulnerability Patched

msm1267 writes: A patch for a critical Linux kernel flaw, present in the code since 2012, is expected to be pushed out today. The vulnerability affects versions 3.8 and higher, said researchers at startup Perception Point who discovered the vulnerability. The flaw also extends to two-thirds of Android devices, the company added. An attacker would require local access to exploit the vulnerability on a Linux server. A malicious mobile app would get the job done on an Android device. The vulnerability is a reference leak that lives in the keyring facility built into the various flavors of Linux. The keyring encrypts and stores login information, encryption keys and certificates, and makes them available to applications. Here’s Perception Point’s explanation of the problem.

Graphene Flakes Facilitate Neuromorphic Chips

An anonymous reader writes: One of the hot areas of semiconductor research right now is the creation of so-called neuromorphic chips — processors whose transistors are networked in such a way to imitate how neurons interact. “One way of building such transistors is to construct them of lasers that rely on an encoding approach called “spiking.” Depending on the input, the laser will either provide a brief spike in its output of photons or not respond at all. Instead of using the on or off state of the transistor to represent the 1s and 0s of digital data, these neural transistors rely on the time intervals between spikes.” Now, research published in Nature Scientific Reports has shown how to stabilize these laser spikes, so that they’re responsive at picosecond intervals. “The team achieved this by placing a tiny piece of graphene inside a semiconductor laser. The graphene acts as a ‘saturable absorber, ‘ soaking up photons and then emitting them in a quick burst. Graphene, it turns out, makes a good saturable absorber because it can take up and release a lot of photons extremely fast, and it works at any wavelength; so lasers emitting different colors could be used simultaneously, without interfering with each other—speeding processing.” Read more of this story at Slashdot.

Trend Micro Flaw Could Have Allowed Attacker To Steal All Passwords

itwbennett writes: Trend Micro has released an automatic update fixing the problems in its antivirus product that Google security engineer Tavis Ormandy discovered could allow “anyone on the internet [to] steal all of your passwords completely silently, as well as execute arbitrary code with zero user interaction.” The password manager in Trend’s antivirus product is written in JavaScript and opens up multiple HTTP remote procedure call ports to handle API requests, Ormandy wrote. Ormandy says it took him 30 seconds to find one that would accept remote code. He also found an API that allowed him to access passwords stored in the manager. This is just the latest in a string of serious vulnerabilities that have been found in antivirus products in the last seven months. Read more of this story at Slashdot.

BBC Confirms 50% Bitrate Savings For H.265/HEVC Vs H.264/AVC

An anonymous reader writes: A research team from the BBC has done a series of tests to confirm earlier computations showing a ~50% savings in bit rate for H.265/HEVC compared to video using H.264/AVC at comparable quality. “The subjective tests used a carefully selected set of coded video sequences at four different picture sizes: UHD (3840×2160 and 4096×2048), 1080p (1920×1080), 720p (1280×720) and 480p (832×480), at frame rates of 30Hz, 50Hz, or 60Hz. The video content was chosen to represent diverse spatial and temporal characteristics, and then coded using HEVC and AVC standards at a wide span of bit rates producing a variety of quality levels.” Here is the full published analysis. “The tests confirmed the significant compression efficiency improvements achieved in HEVC, verifying the results previously reported using objective quality metrics (PSNR based methods).” The team did not test against VP9, which is shaping up to be an impressive standard as well.

Questions Linger As Juniper Removes Suspicious Dual_EC Algorithm

msm1267 writes: Juniper Networks has removed the backdoored Dual_EC DRBG algorithm from its ScreenOS operating system, but new developments show Juniper deployed Dual_EC long after it was known to be backdoored. Stephen Checkoway, assistant professor of computer science at the University of Illinois at Chicago, said that he and a number of crypto experts looked at dozens of versions of Juniper’s NetScreen firewalls and learned that ANSI X9.31 was used exclusively until ScreenOS 6.2 when Juniper added Dual_EC. It also changed the size of the nonce used with ANSI X9.31 from 20 bytes to 32 bytes for Dual_EC, giving an attacker the necessary output to predict the PRNG output. ‘And at the same time, Juniper introduced what was just a bizarre bug that caused the ANSI generator to never be used and instead just use the output of Dual_EC. They made all of these changes in the same version update.’ Read more of this story at Slashdot.

Planetary Resources Reveals Out-of-This-World 3D Printing

Zothecula writes: If one is going to get into the asteroid mining business, one needs to prove that you can do something with what’s brought back. That seems to be the thinking behind Planetary Resources’ recent presentation at CES in Las Vegas, where the asteroid mining company unveiled the first object 3D printed using extraterrestrial materials. Made in collaboration with 3D Systems, the nickel-iron sculpture represents a stylized, geometric spacecraft, such as might be used for asteroid mining or prospecting. Planetary Resources says it is representative of what could be printed in a weightless environment. Read more of this story at Slashdot.
