Twitter accounts of large companies, politicians and celebrities hacked for cryptocurrency fraud

Twitter accounts of various companies and individuals have been hacked in order to conduct fraudulent transactions with bitcoins. Fraudsters publish the addresses of cryptocurrency wallets in verified accounts, offering to double any incoming payment. Among the victims are Elon Musk, Bill Gates, Jeff Bezos, Barack Obama, Joe Biden, Michael Bloomberg, as well as Apple, Uber and others.

It all started with the hacking of Elon Musk’s account, in which the first message appeared with a proposal to double the payment in bitcoins entering a special wallet. A little later, a similar message appeared on the page of Microsoft co-founder Bill Gates, and even the wallet address was the same that was previously “lit up” in Elon Musk’s account. For a while, new fraudulent tweets appeared in each of the mentioned accounts with a high frequency. Later, a spokesman for Bill Gates confirmed that the publications appeared as a result of a hacked account.

The first tweets were soon followed by a second wave of similar publications. Messages were posted on the official pages of former US President Barack Obama, US presidential candidate Joe Biden, billionaire and former mayor of New York Michael Bloomberg, Amazon CEO Jeff Bezos, rapper Kanye West, as well as Apple and Uber accounts.

It is unclear how widespread the attack is, but it appears to be affecting the accounts of various large companies, politicians, and celebrities. This may mean that the hackers managed to find a serious vulnerability in the authorization mechanism on Twitter, or someone was able to gain access to the administrative privileges of a social network employee.

Twitter acknowledged the existence of a large-scale problem, saying that an investigation into the incident is currently underway. Later, the technical support of the social network wrote a message in which it was said about a temporary ban on the publication of tweets and changing passwords for verified accounts.

Galaxy Note 20 may be the first Samsung smartphone with wireless desktop DeX mode

Galaxy Note 20 may be the first Samsung smartphone with wireless desktop DeX mode

The Samsung DeX function implies several ways to connect your smartphone to an external monitor or PC. What unites them is that in all cases a cable is used. However, DeX may soon become fully wireless technology. Moreover, in this version, it may appear already in the Galaxy Note 20.

The evidence of the development of the DeX wireless mode was found in the form of a recording in the Samsung Tips application, which gives users tips on how to use certain functions of Galaxy smartphones. Instead of a title, the post contained the following line: DREAM_DEX_HEADER_USE_DEX_WIRELESSLY_M_TIPS. The strange format of the text indicates that it got into the application by mistake and clearly prematurely.

Further, the message, already in normal English, explained how to connect the Samsung DeX to a TV in the living room without a cable. The advice was accompanied by a visual animation of what actions the user should perform to connect. The presence of ready-made instructions may indirectly indicate that the function is almost ready for implementation in one of the smartphones of a South Korean company. It may well be the Galaxy Note 20, which is scheduled to be announced on August 5th.

This is not the first time we’ve learned about Samsung’s intention to free DeX mode from wires. The company first reported this two years ago. Since then, DeX has received many new features, in particular, it became possible to connect the smartphone via a USB cable to a computer or laptop on Windows or Mac platforms. Only the wireless version of DeX has not yet appeared.

Recall that DeX is a mode that adds functionality similar to a desktop device to a mobile device, allowing you to connect computer peripherals to it. After connecting the monitor, the user is provided with an interface oriented to work with the mouse and keyboard and supporting operation in windowed mode.

Spotify took less than a day to become the leader of the Russian App Store

Spotify took less than a day to become the leader of the Russian App Store

The popular streaming music service Spotify started operating in Russia and 12 other countries of the European region yesterday. Less than a day has passed since the launch, and the mobile versions of Spotify have already become real hits in the Russian digital content stores Play Market and App Store, and in the latter service it has taken the lead in the ranking of free applications.

In the Play Store, Spotify’s success is not so great, but the Android version of the service has already outperformed its direct competitor Yandex.Music in the top of free apps and is currently ranked 14th. The results look very impressive, especially when you consider that the service worked in Russia for less than a day.

An important component that has helped Spotify gain worldwide popularity is the large number of podcasts. Unfortunately, podcasts are not yet available in Russia, because this segment of the market in the country is not sufficiently developed. According to reports, the service plans to implement podcast support for Russian users in the future. It is noted that this direction is important, and its launch will take place as soon as the service and the market are ready for this.

Recall that you can start using the Spotify streaming service for free using the web version, desktop client or mobile application. Some advantages when interacting with the service gives a premium subscription. You can get it for one person for 169 rubles a month, for two it will cost 219 rubles a month. There is a family tariff, within which it is allowed to connect up to six users for 269 rubles per month. Students are offered a 50% discount, and the first three months at any rate there is no charge.

Mobile Intel Tiger Lake processors will be presented on September 2

Mobile Intel Tiger Lake processors will be presented on September 2

Intel has begun sending out invitations to reporters from around the world for the closed online event, which it is planning to hold on September 2 this year.

“We invite you to an event where Intel will talk about new opportunities for work and leisure”, – the text of the invitation says.

Obviously, the 11th generation of Tiger Lake series mobile processors is the only true guess about what Intel is going to present during this planned event.

Over the past months, rumors and leaks about them have very often appeared on the Web. It is known that they are created using a 10-nm third-generation technological process, improved relative to the process technology that is used in the 10th generation of Ice Lake processors. In addition, the new processors will receive a new graphics architecture of the 12th generation Intel Xeable to demonstrate a twofold increase in performance compared to the 11th generation of Intel graphics. Improvements are also expected in computing performance: they should be provided by the new Willow Cove microarchitecture.

New “blue” processors will have to compete with AMD mobile solutions manufactured using 7-nm standards. Against this background, many criticize Intel for the fact that it too delayed the release of 10-nm processors. And indeed, most of the chips of the current generation use the same, albeit slightly modified 14-nm process technology, which has been used by the company since the time of the Skylake family of processors. Only a part of Intel’s 10th generation processors, namely representatives of the U- and Y-series for mobile systems, use the 10-nm process technology.

Presumably with the release of Tiger Lake, Intel will finally abandon the use of the old process technology in mass mobile chips and will be able to offer corporate clients and ordinary users something truly new.

Gigabyte W480 VISION D motherboard – a reliable base for workstations with Intel Xeon W-1200 / ServerNews

Gigabyte W480 VISION D motherboard - a reliable base for workstations with Intel Xeon W-1200 / ServerNews

Gigabyte W480 VISION D is a motherboard for a productive, reliable and inexpensive workstation based on the latest Intel Xeon W-1200 CPUs. A wide range of interfaces makes it possible not only to equip it with all the necessary components, but also makes it easy to update them in the future

As an advertisement

Along with the 10th generation Intel Core Comet Lake-S, the company introduced the Xeon W-1200 series of processors for entry-level workstations. Both series, as before, have a common base platform, but differ in detail. The fundamental difference between Xeon-W and Core is the support of DDR4-2933 RAM with ECC error correction and up to 128 GB. Ordinary, even powerful gaming systems do not need it, but for calculations and simulations, that is, typical workstation loads, its support is critical.

Thus, it is the Intel Xeon W-1200 that allows you to assemble a relatively inexpensive machine for professional tasks. In addition, the new generation has more cores with a higher frequency, which also has a positive effect on performance in workloads.

A separate W-series chipset is designed for Intel Xeon, and all the platform features are presented in the older version of W480. It is on it that the ATX Gigabyte W480 VISION D form factor motherboard is built, also the oldest (and the most complete) in the company’s family of motherboards for workstations. It supports the installation of “regular” processors of the 10th generation Intel Core, Pentium and Celeron, if someone suddenly needs this configuration without ECC, but, for example, with XMP profiles.

A characteristic feature of the novelty is its black and white design, but this is not a designer refinement in its purest form. White radiator shields cover the processor power subsystem, the chipset and M.2 M-key slots of which there are three at once: two 2280/22110 SATA + PCIe x4 / x2 and one 2260/2280/22110 PCIe x4 / x2. Intel RST will enable RAID0 / 1/5/10, and Optane support will speed up the storage subsystem, which also includes six SATA3 ports. By the way, a RAID array, if desired, can be assembled from M.2 drives, having at the same time higher speed and increased reliability.

Four PCIe slots are available for connecting cards. Three sizes x16, which account for 16, 8 and 4 physical lines, respectively, and one PCIe x1. In total, the system provides 40 PCIe 3.0 lanes. Of these, 16 lines are provided by the CPU – they can be sent to the first x16 slot or distributed in half (x8) between the first two slots. The remaining lines are provided by the chipset; they are divided between the remaining slots and M.2. It is curious that the wiring is made taking into account the PCIe 4.0 standard. Yes, now the platform only supports PCIe 3.0, but from compliance with more stringent than necessary requirements for signal integrity, it certainly will not be worse.

The diversity of x16 slots on the board allows you to install up to three typical dual-slot expansion cards, provided that the chassis has an upper location for the power supply. However, again, a typical set of two cards (with a bridge if necessary) – for example, for AMD CrossFire – does not impose such a limitation. However, one thing to keep in mind is that the board offers two Type-C ports with Thunderbolt 3 support, which also require PCIe lanes, and with the ability to connect a chain of 6 devices (Daisy-Chain) through one port, which greatly simplifies cable management when connecting multiple monitors, docks and drives.

These ports can display DisplayPort / Thunderbolt video on compatible monitors, they support super resolution 5120 × 2880 @ 60 Hz 24bpp and DisplayPort 1.4, HDCP 2.3 and HDR standards. Moreover, there is also a DisplayPort 1.4 input, which allows you to pick up output from an external card, “drive” it into Thunderbolt and transfer it further down the chain, if necessary. However, for the graphics integrated into the processor, there is also a regular HDMI 1.4 port (HDCP 2.3) with support for resolutions up to 4096 × 2160 @ 30 Hz. And Type-C ports can work in regular USB 3.2 Gen2 mode.

The rear panel also has two USB 3.2 Gen 2 Type-A, two USB 2.0 Type-A and four USB 3.2 Gen 1 Type-A, two of which have the DAC-UP function, that is, they have independent power lines, which reduces interference when connecting, for example, USB audio devices. The onboard audio subsystem is represented by the Realtek ALC1220-VB HD codec with support for DTS: X Ultra and 7.1 sound – five 3.5 mm connectors and an optical S / PDIF are displayed on the rear panel. The pads on the board allow you to additionally output one USB 3.2 Gen2 Type-C, two USB 3.2 Gen1 and four USB 2.0.

To increase reliability and usability, there are several components on the board. Firstly, there is a digital indicator of POST codes. Secondly, there is a connector for the TPM module. Thirdly, there are pads for connecting external temperature sensors. For connecting coolers, there are 8 connectors at once, three of which are oriented to the SJO. Smart Fan 5 software will help to set up quiet but effective cooling. In addition, the proprietary QFLASH technology for updating BIOS / UEFI directly from a USB flash drive and without installing a CPU, RAM and GPU has not gone away. They didn’t forget about the beauty either – there are four connectors for RGB tapes on the board, including addressable ones.

The network subsystem received a very remarkable upgrade. 2.5GbE was added to the usual 1GbE port. This is actually a very good compromise between the expensive 10GbE connection and the massive 1GbE. The new standard gives a speed increase, but at the same time it is compatible with the existing cable infrastructure based on Cat.5e. If you don’t like the cable, there is an on-board Wi-Fi 6 module (802.11ax 2 × 2) with a “clean” speed of 2.4 Gb / s (the real one will be slightly less) – a compact antenna with a magnetic mount is included. However, the presence of Wi-Fi is optional. In new Intel platforms, a separate M.2 CNVi-module is used (in this case it is the lower slot on the board), which allows you to install it at any time or replace it with a newer one.

One of the first Gigabyte W480 VISION D boards in Russia turned out to be the company ARBYTE, which has been developing and supplying professional IT solutions for almost 30 years: servers, storage systems, HPC systems and, in fact, graphics and workstations. The company prepared a test assembly based on this board and Intel Xeon W-1290 processor (10C / 20T, 3.2 / 5.2 GHz, L3 20 MB, UHD P620, TDP 80 W), supplemented with 64 GB DDR4-2666 ECC memory (4 × Kingston KSM26ED8 / 16ME) and Samsung 970 EVO + SSDs, as well as alternately NVIDIA RTX 2070 and Quadro P2200 cards.

In the gallery above, the results of some render benchmarks are given separately, as there are enough typical loads for graphstations, but the main test packages for a comprehensive assessment of system performance are the classic SPECworkstation 3 and SPECviewperf 13. For the first, the creation of two threads per core was indicated, and the second left V -Sync (more precisely, it was not forcibly disabled). In the settings of Windows 10 Pro (build 2004), the power policy was set to maximum performance.

For a small comparison, several systems from other manufacturers were selected on the older Intel Xeon processor W-2155 (10C / 20T, 3.3 / 4.5 GHz, L3 13.75 MB, TDP 140 W), which formally belongs to another class (just look at the three-fold difference in price with W-1290), but at least close in the number of cores / threads and also used in workstations. In addition, the list included cars with NVIDIA Quadro RTX 4000, but on two noticeably different CPUs: Intel Xeon W-2265 (12C / 24T, 3.5 / 4.8 GHz, L3 19.25 MB, TDP 165 W) and Xeon E-2288G (12C / 24T, 3.5 / 4.8 GHz, L3 16 MB, TDP 95 W). The latter is interesting because with a formally higher CPU rating and a similar configuration of other components, the system based on it is less productive than the ARBYTE assembly.

In general, complex SPEC tests show not only a certain increase in CPU performance from generation to generation, which even the manufacturer estimates in the range from 5% to 15% depending on the type of load, but, and more importantly, the fact that the motherboard the board in no way limits the rest of the components. So the Gigabyte W480 VISION D is really a good basis for a typical “workhorse”, and at the same time it is inexpensive.

The new Gigabyte W480 VISION series, in addition to the W480 VISION D discussed here, includes two more models: the W480M VISION W and W480 VISION W. The first differs in the Micro-ATX form factor, and the second due to the rejection of Thunderbolt 3 has an additional PCIe x16 slot . However, all three are based on the same design, so the key features – ECC memory support, compatibility with the latest Intel Xeon W-1200, wide expansion options and so on – all W480 VISION boards have it.
