Why negotiations on the acquisition of Tinkoff Bank are terminated: all the details

A transaction involving the purchase of Tinkoff Bank by Yandex IT company from its parent company, which has already received status
the largest in the non-resource market will not take place. The parties – TCS Group and Yandex – announced the completion of negotiations, the shares of both companies slightly decreased against the background of this news, and experts are building
versions of the reasons for what happened.

The news about the upcoming purchase of one of the leading Russian IT companies of the most technologically advanced Russian bank excited the market no less than information about the division of assets between the same IT company and
its largest partner in the retail banking market, which also has one of the most extensive ecosystems in Russia – Sberbank of the Russian Federation (now Sber). Recall that in the first weeks of summer
This year, Yandex withdrew from both joint projects with the bank, buying its share in the Yandex.Market JV and selling it its share in the Yandex.Money project.

In mid-September of this year, even before the final division of assets with the former partner, the IT company announced a preliminary agreement involving the purchase of another strong player,
the merger with which would make it not only the direct and most visible competitor of the former partner, but also the most powerful figure in the domestic financial technology market – Tinkoff Bank. Amount
the contract was estimated at $ 5.48 billion.

However, on October 16, official information was received that a new potential “deal of the century” would not take place.

“After further discussions, including with the controlling shareholder of Tinkoff Bank, the parties agreed not to continue the potential deal. Thus, negotiations between the parties regarding
potential transactions were immediately terminated, “- this information was posted on October 16 in a release on the official website of the London Stock Exchange.

The main reason for the collapse of the deal is called the fact that the parties could not come to a decision on the final terms of the deal, which would suit both.

So, Oleg Tinkov himself, the founder and chairman of the Board of Directors of Tinkoff Bank, intended to remain in the company after the completion of the transaction. True, he did not specify in what capacity. He also
emphasized that “he has not sold anything yet” and said that he looks at the deal as a merger, not a sale, “Meduza quotes him with a link to Instagram posts in recent numbers.
September.

In mid-October, according to media reports, Oleg Tinkov also announced other possible options for selling the bank, naming potential buyers, including MTS and MTS Bank and
stressing that he has not reached final agreements with anyone yet.

And literally two days after that, on October 16, Oleg Tinkov sent a letter to the employees, where he spoke of his decision to complete negotiations with Yandex and to cancel the deal.

“I made the decision to break off a possible deal with Yandex. Why? We started the conversation by merging, looking for synergies and rapidly growing our client base. And they wanted to build the largest private
company of Russia. In fact, everything turned into a sale, they just wanted to buy Tinkoff, with all the ensuing negative consequences for us. “Tinkoff” is not sold to either Yandex or MTS “, –
says his letter. “I was extremely surprised that there is such a negative attitude towards the Yandex brand, and their consumers do not like it, although, unlike us, they are in a more consumer-friendly
market segment. All this led to the fact that I stopped the deal. We ourselves will grow to 20 million clients, 1 billion in profits, and we will be worth 10+ billion dollars on the exchange. ”

However, Yandex, according to the leading media, believes that the failure of the deal is entirely the responsibility of the founder of Tinkoff Bank.

“We were constantly meeting Oleg halfway in his additional requirements,” the statement of an IT company representative is quoted. – Unfortunately, after each stage of the negotiations, more and more new
requirements. Therefore, when today we learned that Oleg had made a decision to withdraw from the deal, we were not surprised, “Tigran Khudaverdyan, Managing Director of the Yandex Group of Companies, writes in his letter.
which is also quoted by the media.

Whether Oleg Tinkov will continue further negotiations on the sale of his bank with other partners is still unknown. But, experts say, the likelihood of this is quite high. So, for example, according to the opinion
leading analyst at FxPro Alexander Kuptsikevich, in the end the businessman will still sell his bank, because before he always sold his businesses. And the entrepreneur, in addition to the bank, had them
a lot – he is the founder of the Technoshock chain of household appliances stores, the Daria factories that produced frozen semi-finished products (including the popular Daria dumplings), the brewing company
and the eponymous Tinkoff restaurant chain, as well as the Music Shock music store and Shock Records.

“This is not even a hype, but an attempt to praise the goods, as they do in the oriental bazaar. Do not be surprised if in the coming days we hear about a new deal to sell Tinkoff Bank, – the expert concludes.

In connection with the failed transaction, the Central Bank of the Russian Federation intends to check the bank and the IT company for signs of insider trading and identify suspicious transactions affecting quotes. About it
reported in the press service of the regulator with reference to the director of the department for combating unfair practices Valery Lyakh.

Against the backdrop of news of the breakup of the deal, the shares of the failed partners fell in price. So, on October 16, Yandex shares fell by more than 4% at the moment, TCS Group Holding – more than
than 7%. True, according to the trading data of the Moscow Exchange, later the quotes rolled back somewhat from the lows reached. Thus, by 12.26 Moscow time, Yandex shares were down 2.94%, TCS depositary receipts
Group Holding – by 4.41%.

PC market skyrockets to 10-year high because coronavirus is here to stay

Given that the coronavirus is not losing ground, many people are striving to equip their remote workplaces with quality. PC sales have skyrocketed since 2011 according to Canalys
level.

In the third quarter of 2020, global PC shipments grew 12.7% year-over-year to 79.2 million units. Sales of laptops and mobile workstations increased by 28.3%
compared to last year, up to 64 million units. At the same time, sales of desktop PCs decreased by 26%.

The main lucky ones in the third quarter were Lenovo, which increased shipments by 11.4% to 19.3 million units, and HP, which increased sales by 11.9% to 18.7 million units. But companies
Dell was out of luck, with shipments down 0.5% to 11.9 million PCs. Apple is in fourth place with sales growth of 13.2% to 6.4 million devices. Closes the top five Acer leaders, increasing
deliveries by 15% to 5.6 million units.

Analysts are seeing a powerful wave of demand from both the corporate segment and the consumer sector. In some countries, the authorities actively contribute to the process: for example, in
The UK government has provided students with 100,000 laptops so that they don’t have problems with distance learning.

It is noted that as the border between home, office and school is blurred due to the pandemic, people need devices with a good level of mobility, Internet access, powerful
battery, acceptable audio level and high quality screen.

With the coronavirus still in place, PC demand is expected to remain strong for quite some time.

Employees of hi-tech companies in the USA donate millions to support Biden

Employees of Amazon, Microsoft, Oracle, Apple, Facebook and Google have already donated $ 4.8 million to Joe Biden’s election campaign to Donald Trump from specialists from large hi-tech companies
got much less, only $ 240 thousand. At the same time, those who spent less than $ 200 were not counted. This is reported by the Wired edition.

The data is quite reliable and taken from the Federal Election Commission. According to American regulations, citizens who donate more than $ 200 to this or that policy are required to report where they work.
The total number of employees Amazon, Microsoft, Oracle, Apple, Facebook and Google, who contributed to the election on one side or another, amounted to 5,300 people. At the same time, Google employees
spent most of all on supporting “their”, one or another, candidate, $ 1.8 million.

Trump was more or less loved only at Microsoft; also in support of Donald Trump is the head of Oracle Larry Ellison.

Earlier, we will remind, in hi-tech companies, the USA actively supported Hillary Clinton, Trump is traditionally not honored there.

Perhaps not the last role is played by the constant “trade wars” of the Donald Trump administration, either against China, then against Europe, or the closure of borders for migrants, among whom there are many employees
large companies. Very few people like “sitting on a volcano”.

The Challenges of Hybrid Cloud Management

The Challenges of Hybrid Cloud Management

The combination of private and public clouds, also referred to as hybrid cloud, now looks like the most natural way to evolve IT infrastructure for medium and large organizations. In theory
this model allows you to combine the advantages of both approaches – the flexibility and scalability of public services, and the reliability and manageability of your own data centers. Thus, each
the application can be placed in the most suitable environment for it. Unsurprisingly, according to ECI 2019 research, 85% of companies consider hybrid cloud to be the ideal IT model.

But what about the other side of the coin? To better understand the key challenges facing hybrid cloud operations, Vanson Bourne, commissioned by Nutanix, surveyed 650
IT decision makers from different companies around the world.

The study found that 96% of companies (that is, almost all) faced difficulties in managing applications and data when they were hosted in the private and public clouds. 69% said that
the transition to this model is taking longer than they expected.

Part of the problem is the public component of the hybrid cloud. It turns out that offloading workloads to public cloud platforms is much easier said than done. 71%
of respondents noted the complexity of migration, and 75% indicated the need to adapt or reengineered applications as the main obstacles to the transition to the public cloud. And for some
applications, such a transfer was not possible.

The main problem of managing multiple environments – private and public – is concerns about data security, as stated by 54% of respondents. The next priority problem is personnel, it
only 1% yielded the safety palm. The staffing shortage is understandable if we remember that different tools and knowledge are needed to work with local infrastructure and cloud services.
For example, 88% said they lack qualified IT staff to manage a hybrid cloud. It is noteworthy that half of the companies realized the problem only when they had already started
migration.

As companies have to rely on separate teams to operate the public and private cloud, this, along with the complexity of migrating applications and data, increases isolation.
used cloud environments from each other. Such fragmentation increases costs: 49% of respondents noted an increase in the required resources, 45% of an increase in costs, and 43% indicated ineffective
resource usage. Another 34% said they noted slower decision-making. In the current environment, when many are focused on optimizing resources and the rate of change, this data can
exacerbate concerns about investing in this model.

Another block of problems is related to the product licensing policy, which in its current form is not very suitable for a hybrid cloud. 58% of organizations faced licensing difficulties, and
the same number noted the problem of supplier dependence.

However, the respondents, despite all the difficulties of the current implementation, demonstrate an amazing solidarity on the prospects for the development of the hybrid cloud. 95% believe their organizations will
a cost-effective solution that provides consistent operations in public and private clouds. This requires the right management tools – 96% of respondents think so, and another 88% are sure that they
will help standardize and simplify cloud operations.

Speaking about Russian realities, we can note a lower level of penetration of cloud services – both their public data centers and private ones – in comparison with the countries that took part in the survey.
At the same time, the rapid development of domestic cloud providers and their services confirms that we are in the position of quickly catching up. It is all the more important to anticipate difficulties and take into account the experience of companies,
passed this way.

Research findings suggest that it is a unified hybrid cloud environment that delivers consistent experiences, tools, and practices across private and multiple public domains.

Iranian hackers sell access to hacked companies to anyone

Initial access data obtained during attacks on corporate VPNs are sold by Iranian hackers on the forum to anyone who wants to buy it. This is reported by the ZDNet edition with
a reference to Crowdstrike. The largest wholesale buyers of such information are extortionist gangs.

The seller is the hacker group Pioneer Kitten (also known as Fox Kitten and Parisite). Crowdstrike believes that the Iranian group offering for sale
access to a number of hacked companies, cooperates with the Iranian authorities.

It is assumed that Pioneer Kitten gained access to companies using VPN vulnerabilities, and then other attackers “dug” into these companies, in particular those who supplied the stolen
information to the Iranian leadership. Access to those companies that did not possess the information necessary for the Iranian authorities was sold on the forum, and there is no waste of good, at least some kind of monetization.

Most of all, Iranian hackers are interested in enterprises in the United States, Israel and the Middle East. Defense businesses are a tidbit, but Pioneer Kitten is also interested in healthcare,
high-tech companies and government agencies. What they hacked, but was of no use to anyone, is for sale.

It is noted that the largest wholesale buyer of “initial access” to company data (initial access) are gangs that encrypt company data and demand a ransom for decryption. That is, in
Pioneer Kitten opens locked digital doors with malicious tools and gives the keys to everyone. The prices for such “keys” are not reported in the ZDNet material.

FAS against Apple: let third-party developers enter the App Store without moderation

FAS against Apple: let third-party developers enter the App Store without moderation

The Federal Antimonopoly Office found Apple guilty of abusing its dominant position in the iOS mobile application market. The investigation lasted
year. Apple will have to address the violations. However, the company itself does not agree with the FAS verdict.

The reason for initiating the case was a complaint from Kaspersky Lab.

According to its management, Apple rejected the versions of the parental control program Kaspersky Safe Kids developed by the company without any reason.

Apple has been pursuing a policy that limits the tools and capabilities for developing parental control applications for nearly two years, according to informed media. So, in one
from its official statements, the company explained the removal of third-party parental control applications from the App Store by the fact that they did not meet the requirements for
user security and privacy.

Interestingly, experts note that the beginning of this policy of restrictions coincides with the release of Apple’s pre-installed Screen Time application. Its functionality is similar to
parental control applications. For example, Screen Time analyzes how the user works with applications and websites, and creates detailed daily and weekly reports, which reflect
the total time spent in each application, and many other indicators, including the number of sessions with the gadget. The user thus gets a complete picture of his
work with the device, and, using the App Limits function, gets the opportunity to limit the time of work with a specific application, website or category as a whole.

As a result, a significant part of the functionality of third-party applications was lost. In addition, according to FAS experts, Apple applies non-transparent requirements to software developers.

According to the official message of the antitrust department, the results of the investigation showed that Apple is in a dominant position.
in the market of mobile applications for iOS – in fact, the company’s share is 100%. Customers can install this or that application exclusively from the App Store (about illegal methods
there is no download of speech). In addition, the company abuses its position in relation to developers of parental control mobile applications and restricts competition in the market.
applications for mobile devices running iOS. For example, the company does not allow any third-party applications in the App Store, despite the degree of compliance of the latter with all requirements.
Apple.

Following the investigation, the FAS will send an order to Apple, and the company will have to eliminate all violations specified in the document. As the deputy head of the FAS Alexey Dotsenko stated in the media,
for application developers, access to the App Store is the only opportunity to distribute their products on the iOS operating system, and the conditions for market access without discrimination
are essential to maintaining a competitive environment.

As Eldar Murtazin, an analyst at Mobile Research Group, commented, the amount of the first fine in this case will be insignificant – only 5 thousand rubles. But if the intruder is not the problem
will correct, then the next fine will be a certain part of the turnover, and its amount can reach hundreds of millions of rubles. Apple cannot lose the Russian market and will make concessions, believes
expert.

The top management of Kaspersky Lab, in turn, is satisfied with the decision taken by the FAS. “Abuse of large corporations and the transfer of their market power, with negative effects on
competition in adjacent markets must be suppressed, ”the media leadership is quoted as saying. The company expressed the hope that Apple will correct its policy towards competitors, no longer
will create privileged conditions for its applications and obstruct other companies.

Apple considers the FAS decision unfair – the company plans to file an appeal. As the company commented, the recommendations for parental control apps were
updated because the technologies they use can pose threats to user security and privacy. Parental control apps of all those developers
that use Mobile Device Management technology in accordance with the new standards have been approved and are now available in the App Store. ” The very same Kaspersky Lab,
the initiator of the complaint to the FAS, worked with Apple to ensure that its application meets all the new requirements. At the moment, according to the company, Kaspersky Lab is placing in the App Store
13 of their applications, and the number of updates released for them is already in the hundreds.

How do you like that, Elon Musk? Beta Testers Reveal Starlink Speed ​​Measurements

The results of testing the quality of communication provided by the Starlink network were posted on a number of Network resources. The project was supposed to provide high-speed broadband access
the 5G standard to the World Wide Web of users all over the planet. Has the project achieved the declared indicators?

The Starlink satellite internet network is a project of SpaceX, founded by Elon Musk. As part of this project, SpaceX intends to provide high-speed broadband access
5G standard to the World Wide Web of users all over the planet, including those who live in hard-to-reach areas. The American businessman promised that the speed of his satellite
the Internet will be up to 1 Gbit / s with delays from 25 to 35 ms.

The first two experimental satellites for the global Internet project were launched into low-earth orbit in February 2018. In May 2019, the first batch of 60 workers was delivered into space
satellites of the Starlink system. Today, 653 satellites of the project are already in orbit of the Earth – in mid-August of this year, their 11th batch was launched. In total, according to the SpaceX project, on the Starlink network
42,000 satellites will operate, with all of them expected to be in orbit by the mid-2020s.

The first message via Starlink satellite internet was transmitted on October 21, 2019 – it was published personally by Elon Musk on
your Twitter page

Connecting to high-speed satellite 5G Internet in droves was supposed to begin with residents of the southern states of America – it was calculated that they would be able to access the project already in
late 2020

At the end of June 2020, SpaceX opened a recruitment of beta testers for the project. The requirements for them contained a geographic restriction – they must all be located in the North of the United States or in
southern regions of Canada. Everyone wishing to participate in the tests received ground equipment from SpaceX to connect to the service, and also signed a non-disclosure agreement. Despite the agreement on
non-disclosure, screenshots of Starlink connection quality measurements made through the Speedtest online service began to appear on Reddit.

For example, a Seattle tester showed that the minimum signal latency was 21 ms, the maximum download speed reached 45.9 Mbps, and the maximum download speed was 10.1 Mbps.

A tester from Los Angeles reported a download speed of 17 Mbps, but also a fairly long signal latency of 94 ms.

The worst latency recorded hovered around 40ms with a maximum ping of 90ms.

On average, as experts state, in most of the test measurements carried out, ping “floats” in the range of 30-40 ms, and these results correspond to the average signal latency for all
traditional ISPs with fiber optic networks. True, the data transfer rate in the Starlink network is still very far from the one promised by Elon Musk – 20 times lower. True, the company itself
has repeatedly warned that at the stage of initial network testing, significant deviations from the specified targets are possible. The satellites that provide the Internet are still very
it is not enough, they are not able to ensure its stable operation, and the service itself requires improvement.

It is important that Starlink is working stably, and gives quite vigorous ping in the target area – in the north of the United States, experts cite the media. There are no negative feedbacks from beta testers on the stability of the connection
received. By the time the closed testing stage is completed, experts believe that the quality of communication will increase markedly, and Elon Musk’s service will compete with the largest land-based
communication providers.

Monitoring and treatment devices can now be drawn directly onto the patient’s skin

Monitoring and treatment devices can now be drawn directly onto the patient's skin

Scientists at the University of Houston (University of Houston, USA) have announced the development of a completely new technology, within which monitoring, prevention and treatment of diseases and injuries is performed using
using medical sensors applied directly to the patient’s skin with special ink.

Accurately extracting physiological and physical signals from human skin is critical for health monitoring, disease prevention and treatment, scientists say. Thanks to
direct interaction of electronic devices with the skin can extract information such as the state of the heart, muscles, complex electrical resistance (impedance) and skin hydration.
However, existing devices of wearable electronics – fitness trackers, ECG sensors and a number of other useful sensors, including the latest achievements in the form of flexible and stretchable bioelectronic
patches, able to track the physical activity of the wearer, his muscle signals, heart rate, temperature and moisture indicators of the skin, making it possible to monitor the condition
his health. But all of them have a number of significant drawbacks, the main one of which is high sensitivity to artifacts (errors made during the study) of movement, as well as a lack of
proper adhesion (adhesion) to a biological surface (in this case, to the patient’s skin), especially during movement. All this leads to incorrect interpretation of the results, erroneous
diagnosis and, as a consequence, a significant decrease in the quality of life of patients.

A new type of wearable technology, developed in the United States, is called Drawn-on-skin electronics. Scientists propose to apply various medical sensors and circuits
directly on the patient’s skin. The new technology will allow doctors not only to collect information about his health – to monitor muscle signals, heart rate,
temperature and moisture indicators of the skin – regardless of its physical activity, but also accelerate wound healing.

The technology consists of three different types of special inks with the properties of a conductor, semiconductor and dielectric, as well as a special pen. Multifunctional sensors and circuits –
transistors, strain gauges, temperature sensors, heaters, skin hydration sensors and electrophysiological sensors are “drawn” directly on the human skin using stencils.

Compared to existing wearable and / or printed bioelectronics, Drawn-on-skin electronics offers numerous advantages. So, for its manufacture does not require a complex
specialized equipment, electronic materials can be applied to dynamic active surfaces (patient’s skin), and immunity to motion artifacts is provided without
the need for additional equipment or calculations.

Electrophysiological control of the signal showed Drawn-on-skin electronics immunity to mechanical deformations and movement artifacts, stable operation in the presence of skin secreted
sweat, reliable capture of signals for a long time.

Such sensors are practically not felt by the patient himself. It will not be possible to damage them or remove them from the skin – this was shown by tests for peeling, rubbing and deformation of the skin. Any defects in devices
Drawn-on-skin electronics is very easy to repair, while damage to other wearable devices requires a complete replacement.

Finally, electrical stimulation by electronics applied to the skin has been shown to have beneficial effects on skin damage. Drawn-on-skin electronics electrodes easy
adjust to any shape and size of the wound, the use of pulsed electrical stimulation contributes to their rapid healing, especially in the phases of tissue proliferation and remodeling. In the example,
cited by scientists in the description of the technology, there are skin wounds from comminuted wounds, which soldiers often receive during military operations. The complete healing process of such wounds can take from
several days to several months.

All this makes such solutions almost indispensable for personalized treatment, as well as in situations where access to complex equipment is impossible.

A detailed description of the developed technology and the tests performed are presented in the article “Ultra-conformal drawn-on-skin electronics for multifunctional motion artifact-free sensing and
point-of-care treatment “of the journal” Nature communications “.
