  • A new vulnerability in Intel processors: what are the risks and how to protect yourself?


    Priyanka

    No sooner had the industry moved away from last year's Meltdown and Spectre, as the users faced a new danger — ZombieLoad. At risk were the owners of computers with Intel processors. This vulnerability could allow attackers to remotely steal someone else's data. We tell you how to protect yourself from potential danger.

    ZombieLoad Attack

    Intel confirmed the existence of ZombieLoad vulnerability and told that it consists of four errors in the microcode of processors. All personal computers and cloud servers are subject to hacking, built on Intel chips, released since 2011. This issue does not apply to devices with AMD processors.

    The essence ZombieLoad is the implementation of the attack on the processor by feeding large amounts of information, which he is not able to handle. To prevent failure of the chip addresses to the microcode, performing the restart. One of the errors allows at this point to access all the data that was processed by the processor cores. In normal operation, applications only have access to their own data.

    With ZombieLoad, attackers can find out which sites a user is viewing in real time, steal their passwords and access tokens from payment systems and take possession of other valuable information. However, to do this, a person needs to download the infected SOFTWARE to his computer and run it.

    ZombieLoad Attack

    Apple, Google, Microsoft, Amazon, and other major corporations have already begun distributing updates protecting against ZombieLoad. Intel has also released appropriate patches for all affected processors. The company noted that included in the firmware fix will clear the buffer of CPU in case of overload, thus preventing the access of malware to the data of other apps.

    To ensure the safety of the users of macOS should be updated to version 10.14.5 containing all necessary corrections. Microsoft has also released an appropriate patch for Windows users via Windows Update. If automatic updates installation is disabled on your computer, you should enable this option or download a new firmware version for Intel processors from a special Microsoft website.

      After numerous leaks, Intel introduced the tenth generation of Comet Lake-S desktop processors. They use up to 10 computing cores and are capable of operating at frequencies up to 5.3 GHz. But new products are still built using the old 14-nm process technology.

      The flagship of the new line is the Core i9-10900K with 10 cores, 20 threads, a frequency of up to 5.3 GHz in Thermal Velocity Boost mode, and a TDP of 125 watts. According to Intel, it is 10% more powerful than its predecessor Core i9-9900K (8 cores, 16 threads, a maximum frequency of 5 GHz) in the PUBG game and 63% faster than the three-year-old Core i7-7700K. The company claims that today it is the fastest processor for games in the world. Of course, it comes with an unlocked multiplier.

      In addition to the flagship Core i9-10900, two other models received the unlocked multiplier: the eight-core Core-i7 10700K and the six-core Core i5-10600K. All new tenth-generation chips support memory up to DDR4-2933, 2.5-Gigabit Ethernet, have built-in Wi-Fi 6, and are equipped with integrated Intel UHD Graphics 630 graphics (except the F series).

      Intel also announced a redesigned Extreme Tuning Utility that provides more control over CPU voltage and frequency. For example, it can be used to disable HyperThreading on individual cores, which can significantly reduce the heat during overclocking.
      The timing of the new processors going on sale has not yet been announced.

      Long before the announcement of Intel's tenth-generation desktop processors, their specifications and synthetic testing results had already leaked to the network. Now the prices of upcoming new products have also become known, which were highlighted on the websites of several online retailers at once.

      According to network informants, all chips of the 2020 sample will be manufactured according to the same 14-nm process as the previous generation. Their main differences will be the transition to the new LGA 1200 socket and the increased number of cores in the older line.
      As before, the letter K in the chip name means an unlocked multiplier and overclocking capability on compatible motherboards, and the index F means no built-in graphics. According to the leak, the flagship Core i9-10900 will cost approximately $50 more than the Core i9-9900. In turn, the price tag of Core i7-10700 will increase by $40 compared to the" ancestor", and the cost of Core i5-10600 - by $30. The price for younger CPUs will not differ from last year.


      Insiders claim that the embargo on reviews of new products will be lifted in the period from April 13 to June 26 — such uncertainty in the forecasts is associated with a possible delay in the supply of processors due to the coronavirus pandemic. The announcement of the tenth generation of Intel Core desktop chips is expected on April 30, 2020.

      At the end of April, the tenth generation of Intel Core desktop processors is expected to be announced. According to preliminary information, the 10-core Core i9-10900K will become the flagship of the line. Judging by leaks, it is almost as good as the 12-core AMD Ryzen 9 3900X in terms of performance. Now it has become clear how much more powerful the new product is than its predecessor.

      For the test, the ASRock Z490M Pro4 motherboard with 32 GB of DDR4 memory was used. The source indicates that the Core i9-10900K scored 1,437 points in the single-core test and 11,390 in the multi-core test. For comparison, Core i9-9900K has the following indicators-1340/8787. Thus, the difference between chips in multi-core mode is about 30%. It is worth noting that the new product will have ten cores against eight of its predecessor, as well as a base frequency of 3.7 GHz with the ability to overclock to 4.8 GHz in multi-core mode and up to 5.3 GHz in single-core mode.
      Similar information has appeared before. However, the first leaks indicated increased energy consumption, but Intel seems to have managed to solve this problem. Intel Core 10-generation desktop processors will initially compete with AMD's 7-nm Ryzen 3000-series, but in the second half of 2020, it is expected to receive rivals in the form of Ryzen 4000-series, built on the basis of an improved 7-nm process.

      What is search marketing? A few years ago, this term simply did not exist. However, the rapid development of Internet technologies has led not only to the emergence of this trend but also to its amazing popularity. At the moment, search marketing is known as an effective way of promotion, which includes a range of activities aimed at achieving only one goal - to attract customers.

      If you have not encountered this term before, it's time to get acquainted with it. Search engine marketing involves promotion in search engines in order to attract the target audience. I must say that this is a whole system in which several specialists are involved. They are marketers, programmers, copywriters, designers, etc.
      Compared to other methods of search engine marketing on the Internet has a major advantage. It allows you to reach out to an audience that is interested in the proposal addressed to it.

Customers get what they're looking for, and you get real customers.
      Relevance
      Search marketing is still a fairly new technology. Therefore, users have a logical question: why is it needed and whether it is needed at all? Let's find out.
      So, the main task of search marketing is to attract potential consumers. And not random, but only interested. After all, the offer is addressed only to those who are already looking for a product or service that you are ready to offer.
      However, in order for a user to notice your website among dozens of competitors, it is necessary to use various methods of search marketing. After all, as a rule, scrolling through the issue, the user rarely browses more than ten sites. Competently using the latest technology, you can be in the top ten and get ahead of competitors in the fight for the attention of potential customers.

      The theoretical definition does not always give an accurate understanding. Let's try to find out how search engine marketing works and what it's for.
      So, suppose that a budding entrepreneur decided to open his own business – to sell lingerie in an online store. This is a popular product that is in demand.
      However, in any area, you need advertising that allows you to attract customers. Because their absence means no profit. For start-up entrepreneurs, all costs are on the account, and any advertising is not cheap.
      There are many companies that offer search marketing among other services. You can even link the amount of payment to the result or make parts. That is, first the entrepreneur receives real customers, and then from the profits makes the rest of the payment for such an unusual method of advertising. Convenient to all.

      Goals and Tasks
      Knowing the definition is not enough. You need to know for what purposes search marketing is used.
      Sales. This is the most obvious task that this method of promotion performs. It is necessary to attract interested buyers to the site who will make a purchase. Image. The more often a person will see the logo of your company, the more likely that he will remember you and sooner or later become a client. Reputation. If we are talking about the promotion in social networks, a large value can have reviews. It is advisable to find a way to encourage buyers to leave real reviews. The more positive opinions can be collected, the greater the level of confidence in the company among potential customers. Competition. The market for goods and services is currently oversaturated. That is why it is especially important to compete and win customers over to your own side. Information. You can offer users up-to-date information about the products and services they are interested in. Even if they don't buy anything right away, your company will become an expert for them. In the future, they can return, choosing you among the many competitors.
      Methods and Technologies
      You need to understand that SEM (search engine marketing) is the whole complex of actions, which may include website optimization, contextual and launching viral advertising, and on the Internet resource work more effectively, attracting target customers and converting them into real buyers. So, what are the technologies of search marketing?
      Contextual advertising. Targeted advertising. Search engine optimization. Social network. Let's talk more about some of the technologies listed above.
      Search engine optimization
      This is only part of the marketing campaign. It involves working directly with the promoted site. Moreover, search engine optimization can be both internal and external. In the first case, work with texts published on the website, metatags, links, etc. In the second case, efforts are aimed at increasing the number of links to third-party resources.

      There are a considerable number of factors that allow you to improve the position of the site in search results. A simple user does not need to know all of them. To do this, there is a separate profession, representatives of which are engaged in search engine optimization.
      Contextual advertising
      This system for placing paid ads, created by the search engines. Each user can create their own ads and thus attract the target audience to their own website.
      The advantage of contextual advertising is that the user does not pay for the fact of placing an advertisement. Payment is charged only if the user clicked on the ad and went to the specified site.
      Another important feature is that to get to the top lines do not need long and painstakingly to optimize the site. You can buy this place for a fee, exhibited by the search engine. It is difficult to predict how high the conversion will be in this case.
      Social networks
      These sites are incredibly popular among the population. It is not surprising that this is quite successfully used by marketers. In this case, often published interesting for users' materials, to support communication in thematic communities, etc. In a sense, marketing in social networks can be called hidden. In addition, this method of advertising is not suitable for all companies. Not every product can be advertised with beautiful photos on social networks and enticing texts.

      Search marketing security
      This question becomes relevant if illegal methods of promotion are used. Conventionally, they are called "gray" and " black".
      Above were described exclusively "white" methods of search marketing, which are loyal to the search engines. Such a conscientious promotion requires a lot of time and effort, but ultimately increases the reputation of the site and gives a reliable result.
      Why then use "gray" and "black" schemes? For the reason that not all site owners are willing to invest a lot of time, effort, and money in the fair promotion. However, you need to understand that when using unscrupulous methods then it will be extremely difficult to restore the reputation of the site or even impossible.
      Prohibited method:
      spamming; automatic link exchange and purchase; placement of links to non-thematic sites. Some of these methods can produce results, but they can also lead to a site ban. Then it will disappear from the search results. Is it worth the risk, each site owner decides for himself.

      Disadvantages
      Delayed result. It may take several weeks of hard work to see the first results of search marketing. We must understand that this is a task that involves long-term implementation. Do not take it, waiting for lightning-fast results. Dependence on competitors. Even if as a result of well-organized search marketing you will be able to be in a good position in the issuance, all at any time can change because of the actions of your competitors. Complexity. It is almost impossible to carry out the whole complex of measures to promote the company on the Internet alone. This requires a whole team of professionals, not random people. Financial cost. You will have to pay for both professional services and search marketing. For example, if we are talking about contextual advertising. You need to understand that the promotion cannot be absolutely free.
