Facebook Inc. said it removed 2.2 billion fake accounts in the first quarter, a record that shows how the company is battling an avalanche of bad actors trying to undermine the authenticity of the world’s largest social network.

In the final quarter of 2018, Facebook disabled just more than 1 billion fake accounts and 583 million in the first quarter of last year. The vast majority are removed within minutes of being created, the company said, so they’re not counted in Facebook’s closely watched monthly and daily active user metrics.

“The larger quantities of fake accounts are driven by spammers who are constantly trying to evade our systems,” Guy Rosen, Facebook’s vice president of integrity, told reporters Thursday.

Earlier today, Google and Binomial announced that they have partnered to open source a sophisticated texture compressor and a high-performance transcoder for Binomial’s cross-platform Basis Universal texture format. This format can help solve a long-standing problem in the 3D ecosystem: how can 3D textures assets be efficiently packaged or transmitted for an application in a way that is both compact AND can be efficiently processed by the wide diversity of GPU hardware texture engines - each of which has a preferred native format?

This problem is particularly acute for WebGL/WebXR applications that have to transmit their 3D assets over the network in real-time, but even native mobile and PC games often ship with texture assets in multiple native GPU formats - significantly bloating install sizes and complicating texture transcoding and distribution for developers.

Textures in the Basis Universal format are similar in size to a JPEG image but they can be efficiently and flexibly transcoded to a wide variety of GPU native formats on the target device without needing to be fully decompressed. Google and Binomial are contributing this format to the open and royalty-free glTF standard being managed by the 3D Formats working group at Khronos.


Basis Universal GPU Texture format in glTF

Basis Universal is a "supercompressed" GPU texture and texture video compression system that outputs a highly compressed intermediate file format (.basis) that can be quickly transcoded to a wide variety of GPU texture compression formats: PVRTC1 4bpp RGB, BC7 mode 6 RGB, BC1-5, ETC1, and ETC2. We will be adding ASTC RGB or RGBA, BC7 mode 4/5 RGBA, and PVRTC1 4bpp RGBA next. Basis files support non-uniform texture arrays, so cubemaps, volume textures, texture arrays, mipmap levels, video sequences, or arbitrary texture "tiles" can be stored in a single file. The compressor is able to exploit color and pattern correlations across the entire file, so multiple images with mipmaps can be stored very efficiently in a single file.

A new class of side channel vulnerabilities impacting all modern Intel chips have been disclosed, which can use speculative execution to potentially leak sensitive data from a system’s CPU.

Intel said that the newest class of vulnerabilities, dubbed Microarchitectural Data Sampling (MDS), consist of four different attacks, which all ultimately depend on different ways of executing side channel attacks to siphon data from impacted systems.


The  four different attack vectors are dubbed ZombieLoad, Fallout, RIDL (Rogue In-Flight Data Load) and Store-to-Leak Forwarding.


Intel said that the new MDS class of flaws is addressed in hardware starting with select 8th and 9th Generation Intel Core processors, as well as the 2nd Generation Intel Xeon Scalable processor family. Future chips will also have integrated fixes.

Source: Intel CPUs Impacted By New Class of Spectre-Like Attacks

CVEs assigned for MSD vulnerabilities
- CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS) - CVSS score 6.5: Medium, exploited by Fallout attack
- CVE-2018-12127: Microarchitectural Load Port Data Sampling (MLPDS) - CVSS score 6.5: Medium, exploited by RIDL attack
- CVE-2018-12130: Microarchitectural Fill Buffer Data Sampling (MFBDS) - CVSS score 6.5: Medium, exploited by RIDL attack
- CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM) - CVSS score 3.8: Low, exploited by RIDL attack

Geeks3D's GPU Tools / Glitches in Seascape demo, the return!
« on: May 12, 2019, 09:46:40 AM »
I received this screenshot:

GPU Caps Viewer - Seascape demo, visual glitches

Hardware: GeForce GTX 960M with latest 430.64 driver.

The artifacts are also visible on my RTX 2070. In Vulkan and OpenGL.
It's weird, because I never saw these artifacts nor received feedbacks before. Looks like something has changed in NV drivers recently...

I'm working on the demo...

NVIDIA has fixed several security flaws in recent graphics drivers and, for GeForce users / gamers, it's recommended to install the latest 430.64 that includes all security patches.

NVIDIA has released a software security update for the NVIDIA GPU Display Driver. This update addresses issues that may lead to denial of service, escalation of privileges, code execution, or information disclosure.

NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where the product does not properly synchronize shared data, such as static variables across threads, which can lead to undefined behavior and unpredictable data changes, which may lead to denial of service, escalation of privileges, or information disclosure.

NVIDIA Windows GPU Display Driver installer software contains a vulnerability in which it incorrectly loads Windows system DLLs without validating the path or signature (also known as a binary planting or DLL preloading attack), leading to escalation of privileges through code execution.

NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DeviceIoControl where the software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer, which may lead to denial of service.

We're continuing to expand the impact of Vulkan on Android, our implementation of the low-overhead, cross-platform API for high-performance 3D graphics. We’re working together with our device manufacturer partners to make Vulkan 1.1 a requirement on all 64-bit devices running Android Q and higher, and a recommendation for all 32-bit devices. For game and graphics developers using OpenGL, we’re also working towards a standard, updateable OpenGL driver for all devices built on Vulkan. In Android Q we're adding experimental support for ANGLE on top of Vulkan on Android devices. 

Android Q is the 10th version of Android.

Beginning with Windows Insiders builds this Summer, we will include an in-house custom-built Linux kernel to underpin the newest version of the Windows Subsystem for Linux (WSL). This marks the first time that the Linux kernel will be included as a component in Windows. This is an exciting day for all of us on the Linux team at Microsoft and we are thrilled to be able to tell you a little bit about it.


The kernel itself will initially be based on version 4.19, the latest long-term stable release of Linux. The kernel will be rebased at the designation of new long-term stable releases to ensure that the WSL kernel always has the latest Linux goodness.


During Intel's Investor Day, Intel has revealed some details about its upcoming processors and their manufacturing process:
