1. Hacking organizations use Google search ads to steal more than $50 million in cryptocurrencies;

Tencent Technology News According to foreign media reports, Cisco's cyber security unit "Talos cybersecurity" recently released a report that the Ukrainian hacking group "Coinhoarder" from Blockchain.info users stole more than $50 million worth of digital cryptocurrencies.

Blockchain.info, one of the most popular providers of digital money wallets, and the Talos cybersecurity security team said in a report that the deception techniques used by hackers were simple but harmful.

First, hackers "poison" users' search results by buying popular keyword ads related to digital cryptocurrencies in Google's search engine. Hackers can then steal assets from cryptocurrency wallets.

This means that when people search Google for keywords such as "blockchain" or "Bitcoin wallet," they can see links to malicious websites masquerading as legitimate websites. Once a user enters personal information, hackers can use it to access the user's digital wallet and steal the digital currency inside.

In this way, hackers stole more than $50 million in digital cryptocurrencies from Blockchain.info users over a period of about three years. In fact, the theft began three years ago, but it wasn't until late 2017, when the price of bitcoin approached $20,000, that hackers began to launch a frenzied attack. More than $10 million in digital currency was stolen between September and December last year alone, according to the Talos cybersecurity security team.

Blockchain.info co-founder and CEO Peter Smith says Blockchain.info continues to work with Google every day to combat these phishing sites. Last year, the two sides cleaned up about 10,000 malicious sites. In January alone, the two companies jointly cleaned up another 3,000 such phishing sites.                     

2. Anti-blocking web page "mining kidnapping", learn 3 tricks to refuse to be free miners;

Hackers are also making money from cryptocurrencies, and in 2017 a flood of web-style malicious mining programs began to emerge, burying them in popular websites using users' computer resources to mine, making people wary. It's not just computers, TrendIng Technology points out, that if you often feel like your phone is getting slower or your battery is getting hot, it could become a free digger for hackers.

Web mining programs are based on Coinhive, the most dangerous site

Jane Shengcai, a senior technology consultant at Trend Tech, points out that in the past, malicious mining programs have mostly moved into users' computers in the form of Trojans to steal mines, but since 2017, web-based mining programs have been executed through Javascript, even with the mass spread of malicious advertising. On the 12th, 4,200 websites, including the British and American governments, were also reported to have been planted with malicious mining program codes.

What is a web-type mining program? In the case of Coinhive, which has the highest market share, the program that digs Monroe currency is packaged in Javascript on the browser side, and website operators can use the power of the user's computer to extract Monroe currency by embedding Coinhive program code on their websites. Coinhive wants web operators to use this revenue instead of advertising on the site, while also improving the user experience, while Coinhive draws 30% of that revenue.

Although Coinhive cautions against using the service without prompting users, the fact is that Coinhive has been misused by multiple websites to steal computing resources from users' computers. According to AdGuard's research, nearly 1 billion streaming site visitors are secretly mining.

According to a survey by Qihoo 360's Cyber Security Research Lab, 629 (0.21%) of Alexa Top's 300,000 sites have mining program code embedded in the home page, with porn-related sites as the main body, accounting for 49% of the total, and scams (8%), advertising (7%), mining (7%), film and television (6%) and some of them embedded in 2%. mining sites.

Not only are mining programs embedded in web pages, TrendIng Technology has found that hackers are using Google's online advertising service DoubleClick to spread mining malware, and the number of Coinhive mining programs has suddenly tripled, affecting Japan, France, Taiwan, Italy and Spain.

Anti-blocking web mining kidnapping, learn 3 self-preservation

Trend Technology points out that by avoiding browser execution of JavaScript applications, coinhive mining programs can be prevented from using CPU resources. In addition, regular patching and regular software updates, especially web browsers, can also reduce the impact of cryptocurrency mining programs.

It's not just computers, mobile phones are also affected by web-type mining programs, but they're harder to detect. Jane Shengcai suggests that anti-virus applications with web filtering mechanisms can be used to prevent it. In addition, Trend Micro Zero has launched its browser app, Trend Micro Zero, which blocks inline mining programs and reduces power consumption, but currently only has an iOS version.

3. Is Bitcoin another tulip? has become a cancer that threatens financial security;

Source: CCTV.com

　　Bitcoin's ice fire and blockchain blueprint - Bitcoin, another tulip?

　　BEIJING, Feb. 18 (Reporter Chai Hua) According to China Voice News, if you want to ask the past year's hottest and most mysterious investment concept is what? The virtual currency represented by Bitcoin and the blockchain technology behind it are well-deserved. The virtual currency, which began in 2009, has soared 20 times in the past year and plunged nearly 70 per cent, making it the perfect combination of overnight wealth and dreams in the financial and investment markets.

　　Attitudes toward Bitcoin are equally polarised in the entrepreneurial and investment worlds: its proponents claim it is another internet-level technological revolution, while scantants firmly believe it is just another "tulip mania" that speculators are trying to create. So what exactly is Bitcoin? Can it become legal tender? What will global regulators do in the face of the trading risks involved?

　　The concept of Bitcoin was first proposed in late 2008 by a man with the adn name "Zhongben Cong". Bitcoin is not issued by a particular currency institution, it is based on specific algorithms and is distributed through bookkeeping to ensure that records cannot be tampered with once they are recorded. Bitcoin is the serial number on the face of every banknote, and if you know the serial number on a note, you have it. But can it become legal tender if it looks like the yuan we use? Of course not.

　　Li Aijun, director of the Internet Finance Law Research Institute at China University of Political Science and Law, says that at present, around the world, the nature and legal nature of Bitcoin is divided into three categories: the first category, which is classified as a virtual commodity or digital asset. China's risk warning for Bitcoin issued in 2013 stipulates that it is a virtual commodity, which most countries have designed as a virtual commodity. Second, the virtual currency is classified as a foreign currency. In the third category, virtual currencies can be used as a payment system in the country. Either category, it is a non-statutory currency, and no country has classified it as legal tender.

　　In September last year, before the country's three major bitcoin trading platforms announced they were halting trading, the China Internet Finance Association issued tips on preventing the risks of so-called "virtual currencies" such as Bitcoin. So-called "virtual currencies" such as Bitcoin are increasingly becoming tools for illegal and criminal activities such as money laundering, drug trafficking, smuggling and illegal fund-raising, and investors should remain vigilant, the report said.

　　Li Dongrong, president of the China Internet Finance Association, said there was strong evidence that Bitcoin was being used illegally and that countries attached importance to its research and management. In China, the RMB is the only legal tender, and illegal monetary activities must be resolutely combated.

　　In the same month, JPMorgan Chase CEO Jamie Dimon told a conference at Barclays that "Bitcoin will eventually collapse, it's a scam." In the period that followed, more and more institutions and governments changed their wait-and-see and even encouraging attitudes, with Treasury Secretary Mnuchin saying the U.S. government was keeping a close eye on virtual currencies and banks in countries such as the U.K. banning customers from using credit cards to buy digital currencies such as Bitcoin.

　　International financial institutions have also become more consistent in their attitudes towards virtual currencies such as Bitcoin. Richard Kovacevic, the former CEO of Wells Fargo, once said: "Bitcoin is MLM, it doesn't make sense, I just wonder why it didn't fall even lower." Bitcoin investors bet that others would buy the asset, and some won, but the fundamentals of Bitcoin are meaningless. "

　　"I don't think Bitcoin can be used as a means of payment, VISA doesn't support virtual currency-based transactions, we only support fitocurrency-based transactions," said ALfred Kohli, CEO of VISA. "

　　So what makes such a 9-year-old society so edomy a cancer that quickly becomes a threat to financial security? At home, it may be that "Chinese players" have finally entered the field in large numbers, and once again for speculators to hallucinate the dream of "overnight wealth".

　　At the beginning of 2017, a bitcoin was less than $1,000, and by the end of 2017, it had hit an in-market high of $1,783, and about Rmb120,000 a bitcoin was definitely worth so much attention today.

　　Of course, eye-catching and regulated can't draw an equal sign, and its roller coaster ride is one of the main reasons so many countries and institutions see it as gambling and Ponzi schemes. In 2018, for example, bitcoin fell below $6,000 in just over a month from $20,000, and plummeted 83% in three days on April 10-12, 2013.

　　More importantly, it has spawned a more popular and chaotic token issue, the ICO market, and start-up projects under various guises are offering tokens as much as cow hair to more common investors. And tokens issued into the secondary market, by the capital speculation, similar to centralized bidding transactions, the yield can often reach more than a hundred times. Until July last year, the seven ministries jointly issued a "notice on preventing the risk of token issuance financing", called off and banned domestic ICO activities.

　　"Because the deal was not approved, it was not regulated, " said Meng Tian, deputy director of the Institute of Science and Technology Finance at Shanghai University. It is real-time, without the limit of the degree of rise and fall, easy to speculate, easy to speculate, easy to bubble. "

　　And the "shanzhai currency" MLM scam, which is held aloft under the banner of virtual currency, continues to infringe on the interests of ordinary people. According to media reports, in 2017 alone, the number of major cases investigated and prosecuted by public security organs in various parts of the country in accordance with the law, involving 107 currencies, the amount involved is usually more than 100 million.

　　Shortly before the Lunar New Year, the Financial Times, the central bank's media, reported that regulators would continue to pay close attention to virtual currency-related activities and take a series of regulatory measures, including banning the existence of related businesses, banning and disposing of websites of virtual currency trading platforms inside and outside China, to guard against financial risks and maintain financial stability. In the past half-month, some overseas exchanges, such as Coin Security and Cocoon, have stopped serving Bitcoin users from China. Bitcoin China, China's first and once largest bitcoin trading venue, was acquired by the Hong Kong Blockchain Investment Fund, with all four major shareholders cashing in. A new round of clean-up of virtual currencies has been under way since the beginning of the year.

4. More worth than Bitcoin, is the blockchain patent;

　Author: He Wei

　　Abstract: From the beginning of Bitcoin to the present, there have been more than 2000 related patents, nearly 50% from China. Patent applications have become prefabribriited weapons for many tech giants and forward-looking individuals fighting the future blockchain world.

　　The current hot blockchain is attracting more and more practitioners. Some people are engaged in mining chip research and development, some people are engaged in mining machine sales, some people are engaged in coin issue, some people are engaged in currency speculation ... There are all kinds of roles.

　　In this blockchain profit-for-profit, someone has started the patent layout step by step.

　　First, the giants compete to lay out blockchain patents, only for the future

　　According to News.Bitcoin, there have been more than 2,000 related patents, nearly 50 percent of which are from China, since the beginning of Bitcoin' birth, according to News.Bitcoin. According to the report, among the top 10 bitcoin patents, Bank of America topped the list with 45 patents, Alibaba was fourth, IBM was fifth, Andersen was eighth, and Chinese companies on the list were Bubi Network Technology (seventh), Hangzhou Complex Beauty Technology (9th) and Hangzhou Cloud Network Technology (10th).

　　China's blockchain patents are growing at a much faster rate than the U.S., leading the world, according to the latest China-released 2017 Global Blockchain Enterprise Patent Rankings. Alibaba to 49 of the total number one, these patents are all from the Ant Gold Service Technology Laboratory. This has been interpreted as Alibaba's "all in" blockchain, and there have even been rumours that Alibaba will issue its own virtual currency.

　　In fact, due to the lag in patent applications, the number of patents currently reported and the number of patents are different from the actual number of applications. As you can see, blockchain patents are exploding.

　　Patent applications have become prefabribriited weapons for many tech giants and forward-looking individuals fighting the future blockchain world.

　　Second, blockchain patent layout status quo: finance, application, security direction is the most popular

　　In fact, in addition to the giant early start layout blockchain patents, there is a group also began to lay out blockchain patents, that is, patent investment molecules (patent hooligans). In fact, they are in a group of patent applications that are more sensitive and enforceable than the tech giants.

　　Let's take a look at the current status of blockchain patent layout through the number of patent speculators on the patent layout.

　　At present, by the self-proclaimed "Zhongben Cong" Australian Craig? Nchain, which Wright founded in 2016, is a speculative company that specializes in blockchain patent applications. As of 25 January 2018, Nchain has applied for 156 patents in the UK, some of which were terminated before they were made public and others have not yet been made public, so it is not yet clear exactly what its patent protection is, but some simple inferences can be made from the patent names that have been allowed to be viewed.

　　Most of these patents do not see their specific technology from the name, can generally see the layout of the direction of patents in general distributed in financial transactions, security and applications in three aspects.

　　At present, the financial patent is mainly focused on digital currency, which is also the focus of the current blockchain patent layout, security aspects in addition to the blockchain communication process security and encryption issues, but also consider personal device security issues, applications are mainly economic scenarios outside the use of the scene, currently mainly including the Internet of Things and logic gate functions.

　　In China, blockchain patent application subject has 2 categories, one is a scientific and technological enterprises, one is a university scientific research institutions. The total number of patent applications for blockchain-related patents that have been made public in the Chinese Patent Office is about 1057, of which 1028 are open but not yet authorized for inventions, 16 are granted for utility models and 13 are granted for inventions.

　　Blockchain patents are mainly concentrated in five directions: data storage, data verification, authentication, centering and sharing systems.

　　Compared with domestic and foreign blockchain practitioners in the layout of patent research found that the majority of patent applications are mainly concentrated in finance, applications, security in the three directions.

　　Third, blockchain patents, the future of the blockchain world of prefabribrio weapons

　　According to the China Blockchain Technology and Application Development White Paper, blockchain has a wide range of applications in financial services, supply chain management, intelligent manufacturing, cultural entertainment, medical and health care, etc. Corresponding to the wide range of application prospects is the potential value of blockchain patents.

　　Although we are not yet in a possible situation to specifically assess the future market value of a blockchain patent, we can make some prejudgments from the layout of patents by giants and speculators.

　　1, blockchain patent is the future of the blockchain world's prefabribribried weapons.

　　Blockchain, as the cornerstone of the value of the Internet, is changing the world. There is no doubt that with the application of blockchain technology more and more, blockchain patents will inevitably penetrate into every corner of the blockchain world, patent value will certainly be higher and higher. At that time, blockchain patents will become a powerful weapon for enterprises and subjects to compete in the blockchain world, and blockchain patentees will have to take advantage of the industry.

　　2. Blockchain patents are a powerful weapon against speculators

　　Remember that famous "Gao Zhi Invention" company? It currently operates a total of 1,276 well-known "shell" companies, and as of May 2011, it has 30,000-60,000 patents worldwide, including nearly 8,000 U.S. patents and 3,000 pending U.S. patent applications, covering almost all industrial sectors, from computer hardware to biomedicine, from consumer electronics to nanotechnology.

　　The operational strategy of Gao Zhi Invention is to lay the foundation for the next commercial operation of patent rights by funding inventors from the source of research and development and searching for patents in large numbers to obtain exclusive licenses for patents.

　　According to the data, Gao Zhi Invention has benefited from the patent license of $2 billion.

　　In the future, companies with blockchain patent pools will have an advantage and will not be afraid of the intimidation of patent speculators.

　　In the era of blockchain, enterprises in the blockchain technology innovation and commercial innovation at the same time, do not forget to do a good job of patent layout, to ensure that their enterprises in the future blockchain world competition to obtain more favorable conditions.
