1. bitcoin virus (bitcoin Trojan horse) & quot; Bitcoin blackmailer & quot; It was popular abroad in 2014, and was found in China in early 15 years. This kind of Trojan will encrypt 114 kinds of files in the infected computer, such as docx, PDF, xlsx, JPG and so on, so that it can not be opened normally, and pop up the window & quot; Blackmail & quot; Victim, ask victim to pay 3 bitcoin as & quot; Ransom;, According to the recent price comparison of bitcoin found by the reporter from the Internet, 3 bitcoin is about 5000 yuan or 6000 yuan. This kind of Trojan horse is generally spread through English mail, and the name of the Trojan horse program is usually English, which means & quot; Order & quot& quot; Proct details & quot; And use fax or form icon, which is very confusing. The recipient easily mistakenly thinks that it is a working file and clicks to run the Trojan horse program
in May 2017, computer network virus attacks have spread to 74 countries, including the United States, the United Kingdom, China, Russia, Spain, Italy, etc.

2. Bitcoin is invented by a hacker. It is generated by a large number of calculations on a computer, rather than issued by an institution. Therefore, bitcoin, as a virtual currency, is universal and its price is not affected by an institution or company. The process of procing bitcoin is the computer's incessant calculation. The process of procing bitcoin has an image called "mining", which is like a physical object. Therefore, its value has been growing, and it is favored by hackers (not only hackers, but also investors). In addition, the transaction of bitcoin is anonymous. If the hacker chooses a bank account, there is a risk of being traced, so the hacker will choose bitcoin for blackmail.
3. You can introce bitcoin on the Internet. The characteristics of bitcoin can explain your problem. Many criminals launder money through bitcoin. You can focus on points 2 and 4
1. Complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2. Anonymity, tax exemption and supervision free
3. Robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4. Borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5. It is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical.

4. This begins with a hermit named "Nakamoto Tsung"
on November 1, 2008, the hermit named "Nakamoto Tsung" watched the sky at night. Seeing that the time was ripe, he announced his new idea of issuing an electronic currency called "bitcoin" on a secret cryptography forum
then, in 2009, bitcoin was born
for a while, there were rumors all over the world:
"what is bitcoin?"
"what's the magic power of bitcoin?"
"can it compare with traditional currency?"
it's just a hermit's "masterpiece left behind". Why did it make such a big stir in the world<
it turns out that this bitcoin has risked the world's great injustice, escaped the high-ranking government control, and set up a "small autonomy" on its own:
bitcoin no longer needs to be issued by a specific institution, but is generated through a set of "institutions" designed by Nakamoto Tsung, which is based on a specific algorithm and through a large number of calculations. Regardless of the world, as long as you have a computer, access system, and operate the "organ", you can become a "coin digger"
a thousand waves were aroused for a while, and an undercurrent was set off in the river and Lake: men, women, old and young were yearning to invest in the "money digging fever"<

but since ancient times, unique martial arts skills have come out, and most of the onlookers will see through them, but fengmaolingjiao is the one who really understands the mystery
in the same way, this "coin digger" who creates miracles is not something ordinary people can do at will. Even if everyone has a computer and computing tools, it depends on talent and hard work to generate a new bitcoin
if every "digger" wants to dig bitcoin, he has to go into many "mechanisms" of Nakamoto Tsung and use computers to solve a complex mathematical problem through huge calculation. This is far from enough. Whether we can understand the secret is not only related to the ability of the "coin digger", because the "mechanism" will automatically adjust the difficulty of the questions, so that the whole system will get a qualified answer every 10 minutes, while the vast army of "coin diggers" are crazy computing. Who can understand the secret depends on the nature
it's like buying lottery tickets. Everyone is crazy to generate various combinations of numbers with computing tools in hand. Whoever can guess the same string as the big prize will be the winner
in the end, the lucky person who was lucky enough to get a specific solution successfully created a bitcoin, and the reward for him was a total of 50 bitcoins
at this time, someone will ask, is bitcoin hard to get out of the endless mining
this is the true wisdom of Nakamoto's seclusion
like all kinds of gold, silver, iron and copper veins, bitcoin will be g out one day. A total of 21 million mathematical problems have been designed in the "mechanism" and 21 million corresponding qualified answers have been matched. In other words, the upper limit of bitcoin mining is controlled at 21 million
Where is the mystery
we know that the reason why the government calls the wind and the rain is precisely because it has the power to issue currency. Increasing and recing issuance are "fierce moves" to regulate the economy
and Nakamoto's restriction on the total amount of bitcoin has cut off the way for bitcoin market to be regulated, which is obviously the opposite
which is better? There are two schools in the world:
"supporters" think that eliminating intervention is a sign of social progress
the "losers" feel that fixed aggregate may lead to deflation, which in turn will lead to a series of market weakness and "bone breaking" of the overall economy
the merits and demerits will be left to future generations
since there is a reward for digging coins and the total amount is limited, isn't the mine going to be g through in just a few days
How could the "mechanism" that he had painstakingly researched be easily manipulated by the world<
Nakamoto has two rules under the "agency" neutrality:
first, the more bitcoin, the less reward
- when the total amount reaches 10.5 million hours (50% of 21 million), the reward will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. And so on
secondly, the more the total number of "coin diggers", the lower the efficiency
in this way, bitcoin will be proced more slowly in the later stage. According to the plan, from the birth of bitcoin in 2009, mining will last more than 100 years, and it will not reach the upper limit until 2140
today, the total amount of bitcoin mined out in the world is just over 16 million
all of the above are just a set of "mechanisms" carefully arranged by master Nakamoto. There is another set of "mechanisms" with such precision
bitcoin is a rare thing in the world, so how to trade it? How to manage
after living in seclusion for many years, Nakamoto studied cryptography, a unique security process for bitcoin circulation
the transaction behind bitcoin is very complicated. Bitcoin can generate bitcoin addresses randomly, and each address has a corresponding private key, which is equivalent to the bank card number and the corresponding password. Only when you have both can you manage your money
but is the complexity of this address comparable to that of ordinary bank cards
how confidential is the bitcoin address
each address is made up of a string of letters and numbers about 33 bits long, always starting with 1 or 3
how many such random addresses are there? The answer is: probably more than the sand on earth
it's not easy to break such a complex "secret protection system"
in this way, with the second "organ" blessing of Nakamoto Tsung, bitcoin circulation has more security than ordinary currency
it's no wonder that with the advent of bitcoin, the currency world is shaking, and a new fight is in the dark
bitcoin, like countless secret lone Rangers, grows savagely under the authority of the government. According to the legend, bitcoin is free (decentralized, tax-free, regulatory free), strong (relying on P2P network, external can not be closed), omnipresent (cross-border, borderless), and anonymous
you can understand, "freedom", "coming and going without name" and "omnipresent", which means that bitcoin can not only be tracked and supervised by the government, but also grow wildly in the world. It's a great way for hackers to blackmail
moreover, since last year, bitcoin has been rising wildly, and hackers all over the Internet know this information well
there is no doubt that bitcoin is a safe and profitable way to blackmail

or like this< But all the martial arts in the world are strong. Bitcoin also has weaknesses
there are three pithy formulas:
first, bitcoin network is not broken, and trading platform is fragile
Second, the "black market" trading, speculation rampant, price roller coaster day by day
thirdly, it is difficult for ordinary people to understand the secrets of nature because of their profound martial arts
in particular, the third point is that although the Kung Fu is good, the threshold is too high, which is lamentable
then, if you look at China today, where is bitcoin going
to be fair, in the eyes of the mother of the central bank, it is not too much to say that bitcoin is a barbaric growth: in the past year, with the devaluation of RMB, bitcoin has once again become the target of investors' speculation, and its value has increased by 120%
smart passers-by have already seen through everything

coupled with the emerging bitcoin virus, it seems that it is time for bitcoin to be subject to a wave of regulation.

coupled with the emerging bitcoin virus, it seems that it is time for bitcoin to be subject to a wave of regulation.
5.
Recently, a kind of malicious software that locks up computers is spreading rapidly all over the world. At present, tens of thousands of computers in nearly 100 countries and regions have been attacked. The hackers locked the files in the computer and demanded to pay the equivalent of $300 in bitcoin to unlock the files“ "Bitcoin virus", a virus sweeping the world, suddenly brushed the screen last night. A number of campus networks in Zhejiang Province have encountered similar attacks. Among them, bitcoin, as one of the new payment means, is used by hackers as a payment tool for blackmail
after the regulatory storm in January and February and the big rise and fall behind, bitcoin once again appeared a wave of sluggish market in March: from about 8000 to less than 7000. However, since then, bitcoin ushered in a wave of soaring prices
according to the currency bank's market, the "bull market" of bitcoin started in April. From the price of one bitcoin to 7000 yuan in early April, it rocketed through the threshold of 10000 yuan to one bitcoin
on May 10, the market software showed that the price of bitcoin successfully broke through the 10000 mark, up to 10245. However, since February this year, when the domestic regulatory authorities asked to suspend the withdrawal of bitcoin, there has been a "price gap" between the domestic and foreign bitcoin prices: the foreign bitcoin price was as high as US $1779 / piece, equivalent to about RMB 12275 / piece, and there is a gap of about 2000 yuan between the domestic and foreign bitcoin prices
behind the sharp rise in prices, there is a sharp fall in trading volume. According to public data, the trading volume of fire coin on May 9 was less than 15000 pieces, 40% less than the previous peak day, and 0.3% of the single day trading volume when it reached a new high on January 5 at the beginning of the year
6. Why do you give him the money? If the system doesn't have any important files, reload the system. Do you know how much a bitcoin costs
remember to back up important files next time for a rainy day
and now the virus has been cracked, just follow the process. You give money to help the tyrant
we are 15pb information security ecation, using hacker means to prevent hackers. If you are interested, you can learn about it

7.
as we all know, the "blackmail virus" is rampant all over the world, and hackers ask the "victims" who are recruited to pay bitcoin. According to the data, the price of bitcoin has skyrocketed by 2.21 million times in the past eight years
for the rise of bitcoin price, the Chinese people must have made their own contribution. After all, bitcoin trading in China once accounted for more than 80% of the global trading volume
However, according to the latest data from the research department of fire coin, Japan accounted for 46.4% of the global bitcoin trading volume last week, followed by the United States, accounting for 26.4%, China ranked third, and the trading volume dropped to 10%. Therefore, if the price of bitcoin exceeds 10000 yuan recently, the contribution of Chinese people should be very small8. This is decided by its own characteristics
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items.

9. No, there are several reasons why bitcoin was stolen
1. A stolen bitcoin can't be retrieved, and if it's lost, it's lost.
2. Bitcoin has transaction records, but the address is hidden, and you can't find an indivial.
3. Every bitcoin has a key, and only if you have this key can you be admitted to own bitcoin. However, if bitcoin is stolen or lost, your bitcoin will disappear completely
therefore, the theft of bitcoin does not belong to cracking, it may be e to internal personnel.

10. According to the analysis of 360 security center, the campus network blackmail virus was spread by the "eternal blue" hacker weapon leaked by NSA“ "Eternal blue" can remotely attack the 445 port (file sharing) of windows. If the system does not install the Microsoft patch in March this year, it does not need any user operation. As long as it turns on the Internet, "eternal blue" can execute any code in the computer and implant malicious programs such as blackmail virus.
