1. Hackers use Google search advertising to steal more than 50 million US dollars to encrypt money;
According to foreign media reports, Cisco's network security department 'Talos cybersecurity' released a report a few days ago, the Ukrainian hacker organization 'Coinhoarder' steal digital cryptocurrencies worth more than 50 million U.S. dollars from Blockchain.info users.
Blockchain.info is one of the most popular digital money wallet service providers, the Talos cybersecurity security team said in a report that the hacking techniques used by hackers are simple but dangerous.
First, hackers "poison" users' search results by buying popular keyword ads related to digitally-encrypted currency in Google search engines, after which hackers can steal assets from the encrypted currency wallet.
This means that when people search on Google for keywords such as 'blockchain' or 'bitcoin wallet,' they may see links to malicious Web sites disguised as legitimate websites that hackers can take advantage of once they enter personal information Information to access the user's digital wallet and steal the digital currency inside.
In the above way, hackers stole more than $ 50 million worth of cryptocurrencies from Blockchain.info users in about three years, in fact, stealing started three years ago, but until the end of 2017, Bitcoin Hackers started a mad attack when prices approached $ 20,000, according to data from the Talos cybersecurity security team, with more than $ 10 million worth of digital money being stolen only between September and December last year.
Blockchain.info co-founder and CEO Peter Smith said Blockchain.info has been working with Google on a daily basis to crack down on these phishing sites, and both sides have cleaned up about 10,000 malicious sites last year.Only in January of this year, The two companies have jointly cleaned 3,000 such phishing sites.
2. Anti-blocking page "mining kidnapping", learn 3 recruit as free miners;
Hackers are also making money by encrypting money to dig mining wealth, beginning in 2017 a large number of web-based malicious mining procedures, buried in the popular Web site to use computer resources mining, people are hard to detect.Not only the computer, Trend Micro pointed out that if the often Feel the speed of the phone seems slower and slower or the battery is hot, may have become a hacker free digger.
Web mining program led by Coinhive, pornographic sites the most dangerous
Jane Shing Choi, a veteran technology consultant at Trend Micro, pointed out that in the past, malicious excavation programs were mostly tapped into user computers for stealing and mining in the form of Trojans. However, web-based mining procedures implemented through Javascript have been increasing since 2017 even with malicious Large-scale advertising spread on the 12th came also contains the United Kingdom, the United States government and other 4,200 websites, were implanted malicious mining code.
What is a web-based mining program? The highest market share of Coinhive, for example, it will dig the Monroe program packaged in the browser side of Javascript, web site operators as long as their home site embedded Coinhive code, you can use the user Computing power digging Monroe Coinhive hope that web site operators can use this revenue instead of advertising income on the site revenue, while also enhancing the user experience, and Coinhive pumping 30% from.
Although Coinhive reminds you not to use the service without prompting the user, in fact, Coinhive has been abused by multiple websites to steal the user's computer computing resources.According to the AdGuard study, there are nearly 1 billion streaming media sites Visitors are secretly used in mining activities.
According to a survey conducted by Qihoo 360's Network Security Research Lab (Netlab), 629 (0.21%) of the Alexa Top 300,000 websites have built-in mining code on the homepage, of which pornographic related websites are the mainstay , Accounting for 49% of the total. Others include scams (8%), advertising (7%), mining (7%), film and television (6%), and some content websites also embed 2 or more mines website.
Not only is the mining program embedded in web pages, Trend Micro found that hackers used Google's online advertising service, DoubleClick, to distribute mining malware and triplicate the number of Coinhive mining procedures in Japan, France, Taiwan, Italy and Spain .
Anti-blocking web mining kidnapping, learn 3 strokes self-protection
Trend Micro states that as long as it avoids browser execution of JavaScript applications, it prevents Coinhive mining programs from using CPU resources, and periodically patching and regularly updating software, especially web browsers, can reduce the impact of cryptocurrency mining programs.
Not only computers, but also mobile phones are also affected by the web-mining program, but harder to detect. Simple wins proposal can be protected by anti-virus application with web filtering mechanism. In addition, Trend Micro also launched Trend Micro Zero browser application, Can block embedded mining procedures, reducing device power consumption, but only the iOS version. The digital age
3. Bitcoin is another tulip? Has become a threat to financial security cancer;

Bitcoin ice and block chain blueprint - bitcoin, another tulip?
CNR Beijing February 18 (Reporter Chai Hua) According to the Voice of China "News" reported that if you want to ask the past this year, the most popular and most mysterious investment concept is what? Bitcoin as the representative of the virtual currency With the blockchain technology behind it well deserved.This virtual currency originated in 2009 in the past year soared 20 times, plummeted nearly 70%, becoming a night of financial and investment markets and dreams of breaking through the night The perfect combination of body.
In the entrepreneurial and investment world, the attitude toward bitcoin is equally polarized: its advocates claim it is another Internet-level technological revolution, while the skeptics firmly believe it is just one more attempt by speculators to create Field tulip fanatic. "So what is bitcoin in the end? Can it become the legal currency? Faced with the trading risk which contains, the global regulators who will take countermeasures?
The concept of bitcoin was first proposed by a pseudonym 'Nakamoto' at the end of 2008. Bitcoin is not issued on a specific currency basis and is based on a specific algorithm and distributed accounting ensures that once recorded, it can not be tampered with. In the national currency of the United States frequently used to compare, Bitcoin is the serial number on each banknote face, you know the serial number on a banknote, you have the banknote, but looks like the one we use Renminbi like, it can become a legal currency? Of course not possible.
Li Aijun, dean of the Institute of Internet Finance Law of China University of Political Science and Law said that at present, the essential and legal nature of Bitcoin are divided into three categories in the world: the first is that it is characterized as a virtual commodity or a digital asset. The promulgation of the risk warning on Bitcoin stipulates that it is a virtual commodity, and most countries characterize it as a virtual commodity. The second category characterizes the virtual currency as a foreign currency. The third category, the virtual currency can be used as a national Payment system. In either case, it is a non-statutory currency, and no single country characterizes it as a legal tender.
In September last year, China's three major bitcoin trading platforms announced one after another stop trading business, the China Internet Finance Association issued a warning on the so-called 'virtual currency' against bitcoin, etc. Prompt that bitcoin and other so-called 'virtual currency 'It is increasingly becoming a tool for laundering money, drug trafficking, smuggling and illegal fund-raising activities. Investors should be vigilant.
Li Dongrong, president of China Internet Finance Association, said that there is solid evidence that Bitcoin has been exploited by illegal activities and that all countries attach importance to the research and management of bitcoin. In our country, the renminbi is the only legal currency that is illegal for monetary activities Must be resolutely cracked down.
In the same month, JPMorgan CEO Jamie Dimon blurted out at a Barclays bank meeting that "bitcoin will eventually burst and it is a scam." And for some time thereafter, more and more The United States Treasury Secretary Mu Nuqin said that the U.S. government always focuses on the virtual currency; banks in Britain and other countries forbid customers from using credit cards to buy digital currencies such as bitcoin.
The attitude of international financial institutions towards virtual currencies such as Bitcoin has also become consistent: Richard Kovacevic, former CEO of Wells Fargo, once said: 'bitcoin is a pyramid scheme, meaningless, and I just wondered why it did not Bitcoin investors bet that others would buy the asset while others bet on it, but the fundamentals of bitcoin are meaningless.
VISA CEO Alfred Corey said: 'I do not think Bitcoin can be used as a payment method. VISA will not support virtual currency-based transactions. We only support legal tender-based transactions.'
So what made a concept such as tepid at 9 years old quickly become a cancer that threatens financial security? At home, it may be that finally 'Chinese players' have entered this field in large numbers and Once again for the speculators out of a "fortune overnight," the dream.
At the beginning of 2017, one bit of bitcoin will be less than 1,000 dollars. By the end of 2017, bitcoin hit the highest price of 1,983,300 dollars in the session. About 120,000 yuan of bitcoin definitely deserves so much attention today.
Of course, it is one of the important reasons why gambling and Ponzi schemes are the reasons why so many countries and institutions are attracted by their eye-catching and oversight regulation. The usual roller coaster ride is one In the multi-month period, bitcoin once fell below $ 6,000 from the previous $ 20,000, and bitcoin plummeted 83% in three days from April 10 to April 12, 2013.
More importantly, it has created a more burdensome and disruptive issue of tokens, or the ICO market, under which all kinds of prestigious startups are sending more and more sophisticated tokens to the more popular investors. After the issuance of tokens into the secondary market, subject to financial speculation, similar to the centralized auction transactions, the rate of return can often reach more than 100 times until last July, the seven ministries jointly issued the "Notice on the prevention of financing risks of tokens issuance", stop And forbid the domestic ICO activity.
Meng Tian, deputy director of Shanghai Institute of Technology and Finance, said: "Because the deal was not approved, it was not regulated. It is real-time, and without limit changes, it is easy to speculate, it is easy to hype and it is prone to bubbles. '
According to media reports, in 2017, the major cases investigated and dealt with by the public security organs in various places in the country involved 107 currencies, and the amount involved is usually There are billions.
Shortly before the Spring Festival of the Lunar New Year, the Financial Times, the central bank's bank, reported that the regulators will continue to pay close attention to the fictitious currency-related behaviors and adopt such measures as banning related commercial ventures and banning and disposing of domestic and foreign virtual currency trading platform websites A series of regulatory measures to prevent financial risks and maintain financial stability, while the previous half a month, some of the overseas exchanges such as Monetary Security, Coin Bank and so on have stopped providing services for bitcoin users from China. Home, once the largest bitcoin trading site 'bitcoin China' by the Hong Kong blockchain investment fund acquisition, all four major shareholders to cash in. A new round of virtual currency clean-up rectification from the beginning of this year has been intensely pulling Open battle.
4. More valuable than bitcoin, blockchain patent;
Author: HE Xi
Abstract: Since the birth of Bitcoin, more than 2,000 patents have been filed and nearly 50% have come from China, and patent applications have become prefabricated weapons for many tech giants and forward-looking individuals in the future of the blockchain world.
The current hot blockchain is attracting more and more practitioners.Some people engaged in mining chip research and development, someone engaged in mining machine sales, someone engaged in currency, someone engaged in speculative coins ... ... all kinds of roles everything .
In this blockchain for profit, some people have ancestors began patent layout.
First, the giants rush to layout blockchain patent, only for the decisive battle in the future
Recently, according to News.Bitcoin reports, the "Bitcoin Patent Report" shows that from the beginning of bitcoin to the present, there are over 2,000 related patents, with nearly 50% from China; the slow growth in the previous period and the exponential growth in 2015 The report shows that the top ten bitcoin patents, the Bank of America won the 45 patents, Alibaba ranked fourth, IBM ranked fifth, MasterCard ranked eighth, the same list of Chinese companies also cloth than Network Technology (No. 7), Hangzhou United Technology (No. 9) and Hangzhou Cloud Network Technology (No. 10).
The latest release of the "2017 Global Blockchain Enterprise Patent Rankings" shows that the growth rate of China's blockchain patents far exceeds the United States, leading the world in which Alibaba ranked first in the total 49, all of these patents from Ant gold service technology laboratory.This is interpreted as Alibaba will be 'all in' blockchain, and even rumors that Alibaba will issue their own virtual currency.
In fact, due to the lagging nature of patent applications, the number of patents currently reported and the number of patents differ from the actual number of applications, and it is clear that blockchain patents are showing explosive growth.
Patent applications have become prefabricated weapons for many tech giants and forward-looking individuals in the future of the blockchain world.
Second, the status of blockchain patent layout: financial, application, security direction of the hottest
In fact, in addition to the giants' early placement of blockchain patents, there is another group that has long been involved in the layout of blockchain patents, which are proprietary investors (patent rogues). In fact, they are more smelly than tech giants , More efficient enforcement of patent applications in the group.
Below we pass the number of patent speculators on the layout of the patent, take a look at the current status of blockchain patent layout.
Currently, Nchain, a company founded by Craig Wright, an Australian who claims to be 'Nakamoto', was a speculation firm specializing in blockchain patent applications. As of January 25, 2018, Nchain has been based in the United Kingdom 156 patent applications, but part of the patent application has been terminated before the disclosure, the other part has not yet been open, so it is not clear the exact content of the patent protection, but from the patent name has been allowed to view some simple conclusions can be made .
Most of the patents can not see the specific technology from the name, and can generally see that the patents in the distribution direction are generally distributed in three aspects: financial transaction, security and application.
At present, financial patents mainly focus on digital currency, which is also the focus of the current blockchain patent layout. In addition to considering security and encryption in the process of blockchain communications, security aspects also consider personal device security ; Applications mainly use scenarios outside the economic scenario, the current view mainly includes the Internet of things and logic gates.
In China, there are two main types of applications for blockchain patents, one is technology enterprise and the other is scientific research institution of university. The total number of patent applications for blockchain has been disclosed in China Patent Office is about 1057, of which There were 1,082 open but not yet granted invention patent applications, 16 utility model patents granted and 13 invention patents granted.
Country blockchain patents are mainly concentrated in five directions: data storage, data verification, authentication, decentralization and sharing system.
Compared with the block layout at home and abroad in the patent research found that most of the current patent applications are mainly concentrated in the financial, application, security 3 directions.
Third, the blockchain patents, decisive blockchain the future of the world's prefabricated weapons
According to the White Paper on China's Blockchain Technology and Application Development, the future of blockchain has broad application prospects in various fields such as financial services, supply chain management, intelligent manufacturing, cultural entertainment, medical and health, etc. Corresponding to a wide range of application prospects Of the blockbuster patent has the potential value.
Although we are not yet able to assess the market value of a blockchain patent in the future, we can make some predictions from the patented layout of the giants and speculators.
1, Blockchain Patents is a prefabricated weapon in the future blockchain world.
As the cornerstone of value internet, blockchain is changing the world.Undoubtedly, with the application of blockchain technology more and more, the patent of blockchain will inevitably permeate every corner of the blockchain world and the value of patent will inevitably Higher and higher.At the same time, blockchain patent will become a powerful weapon for the competition between enterprises and the main body in the blockchain world, and the industry has the right to patent the blockchain.
Blockchain patents are powerful weapons against speculators
Do you remember the well-known company of 'Wise Inventors', which now operate a total of 1,276 well-known 'shell' companies with 30 to 60,000 patents worldwide as of May 2011, including nearly 8,000 U.S. patents and With over 3,000 U.S. pending patent applications, the patented technology covers almost all industries, from computer hardware to biomedicine, from consumer electronics to nanotechnology.
The business strategy of 'Wise Invention' is to fund the inventors from the source of R & D and collect a large number of patents to obtain the exclusive license of the patent, laying the foundation for the commercialization of the patent right in the next step.
According to the relevant data, 'Wisdom invention' company has benefitted from the patent license 2 billion US dollars.
In the future, enterprises that own the blockchain patent pool will have more advantages and will not be afraid of intimidation by patent speculators.
In the era of blockchain, enterprises should not forget to do a good job of patent layout while ensuring technological innovation and business innovation in the blockchain so as to ensure their own enterprises get more favorable conditions in the future competition in the blockchain world. exchange
