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.

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.

Cryptsy Bitcoin Trader Robbed, Blames Backdoor In the Code of a Wallet

An anonymous reader writes: Cryptsy, a website for trading Bitcoin, Litecoin, and other smaller crypto-currencies, announced a security incident, accusing the developer of Lucky7Coin of stealing 13, 000 Bitcoin and 300, 000 Litecoin, which at today’s rate stands more than $5.7 million / €5.2 million. Cryptsy says “the developer of Lucky7Coin had placed an IRC backdoor into the code of [a] wallet, which allowed it to act as a sort of a Trojan, or command and control unit.” Coincidentally this also explains why two days after the attack was carried out, exactly 300, 000 Litecoin were dumped on the BTC-e exchange, driving Litecoin price down from $9.5 to $2.

EU Companies Can Monitor Employees’ Private Conversations While At Work

An anonymous reader writes: A recent ruling of the European Court of Human Rights has granted EU companies the right to monitor and log private conversations that employees have at work while using the employer’s devices. The ruling came after a Romanian was fired for using Yahoo Messenger back in 2007, while at work, to have private conversations with his girlfriend. He argued that his employer was breaking his right for privacy and correspondence. Both Romanian and European courts disagreed. Read more of this story at Slashdot.

Verizon Accused of Helping Spammers By Routing Millions of Stolen IP Addresses

An anonymous reader writes: Spamhaus, an international non-profit organization that hunts down spammers, is accusing Verizon of indifference and facilitation of cybercrime because it failed for the past six months to take down stolen IP routes hosted on its network from where spam emails originated. Spamhaus detected over 4 million IP addresses, mainly stolen from China and Korea, and routed on Verizon’s servers with forged paperwork. Spamhaus says, “For a start, it seems very strange that a large US-based ISP can be so easily convinced by abusers to route huge IP address blocks assigned to entities in the Asian-Pacific area. Such blocks are not something that can go unnoticed in the noise of everyday activity. They are very anomalous, and should call for an immediate accurate verification of the customer. Internal vetting processes at large ISPs should easily catch situations so far from normality.” 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.

OCZ RevoDrive 400 NVMe SSD Unveiled With Nearly 2.7GB/Sec Tested Throughput

MojoKid writes: Solid State Drive technology continues to make strides in performance, reliability and cost. At the CES 2016 show there were a number of storage manufacturers on hand showing off their latest grear, though not many made quite the splash that Toshiba’s OCZ Technology group made with the annoucement of their new RevoDrive 400 NVMe PCI Express SSD. OCZ is tapping on Toshiba’s NVMe controller technology to deliver serious bandwidth in this consumer-targeted M.2 gumstick style drive that also comes with a X4 PCI Express card adapater. The drive boasts specs conservatively at 2.4GB/sec for reads and 1.6GB/sec for writes in peak sequential transfer bandwidth. IOPs are rated at 210K and 140K for writes respectively. In the demo ATTO test they were running, the RevoDrive 400 actually peaks at 2.69GB/sec for reads and also hits every bit of that 1.6GB/sec write spec for large sequential transfers.

How We Know North Korea Didn’t Detonate a Hydrogen Bomb

StartsWithABang writes: The news has been aflame with reports that North Korea detonated a hydrogen bomb on January 6th, greatly expanding its nuclear capabilities with their fourth nuclear test and the potential to carry out a devastating strike against either South Korea or, if they’re more ambitious, the United States. The physics of what a nuclear explosion actually does and how that signal propagates through the air, oceans and ground, however, can tell us whether this was truly a nuclear detonation at all, and if so, whether it was fusion or fission. From all the data we’ve collected, this appears to be nothing new: just a run-of-the-mill fission bomb, with the rest being a sensationalized claim. (Related: Yesterday’s post about how seismic data also points to a conventional nuke, rather than an H-bomb.) Read more of this story at Slashdot.

After Years of Serving X11, X.Org Stands To Lose Its One-Letter Domain

An anonymous reader writes: The X.Org domain predates the X.Org Foundation. It was used in the ’90s as a destination by The Open Group around the X Window System. While many are expecting Mir and Wayland to eventually succeed the X.Org Server, it seems the X.Org/X11 Server may outlive the valuable domain. Thanks to poor management by the X.Org Foundation, they risk losing access to their one-letter domain. Procrastination, paired with not transferring the domain when forming the non-profit foundation, has led to a last-minute mess. They left the domain registered for years to a person who is no longer involved with X.Org — and doesn’t want to relinquish it. In the few days until the domain expires, they are hoping for a “Hail Mary.” Let this be a lesson for open-source projects to better manage their assets. Read more of this story at Slashdot.

New Dell Tech Support Scams Have Customers Worried Company Was Hacked

Trailrunner7 writes: A new twist on the fake tech support scam has arisen that has victims wondering whether Dell has been hacked.There has been a recent rash of calls to Dell customers in which the caller says he is from Dell itself and is able to identify the victim’s PC by model number and provide details of previous warranty and support interactions with the company. These are details that, it would seem, only Dell or perhaps its contractors would know. One person who was contacted by the scammers wrote a detailed description of the call, and said the caller had personal details that could not have been found online. Dell officials say they’re looking into it. Read more of this story at Slashdot.
