Malicious infection of mining machine

1.

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer

In his paper, Nakamoto stated:

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

extended data

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

1. Back up important data and photos and restore factory settings. Don't install applications from unknown sources. In addition, don't authorize in permission settings

2. You can swipe the computer to see if it can't work. Besides, the computer needs to clean up the memory on time so that it won't get stuck. The memory of the mobile phone is seriously insufficient. It is recommended to clean up the memory lightly, and then restart your mobile phone again

3. Clear the data of the mobile phone. If there are important things, save them on the network disk first, and then restore the factory settings three times. This is safer

< H2 > extended data:

1. Set the security level of the browser. Our common browsers all have the function of security level setting. Through reasonable setting, we can effectively filter the access restrictions of some illegal websites, so as to rece the damage to computers and personal information

2. Firmly resist reactionary, pornographic and violent websites. On the one hand, these bad information will affect the physical and mental health of teenagers, on the other hand, many illegal websites will use browser vulnerabilities to attack users

3. Don't click illegal links at will

When downloading software and materials, we should choose the regular website or official website

5. Turn off some sensitive functions in common communication software. Such as "people nearby" in wechat and "allowing strangers to view photos" in wechat privacy

6. Do not take photos of your family and address. If it goes on like this for a long time, as long as it is analyzed and summarized by others, the information exposed will become a complete set of information, which hides all kinds of unpredictable risks

Do not test related information on the Internet. Some websites do surveys and ask for information about age, hobbies, gender, etc. to do it for a small profit. This information may be used by others, and graally summarized, and sold to others for profit or threat

In fact, it's not difficult. When we use mobile phones everyday, there will be some background applications, which will be "killed" after restart. However, if the mobile phone is hacked and rebooted, it will enter a high load state again, and the system running memory will be used up quickly. Therefore, if the mobile phone is stuck, hot or dead for no reason, it may be g

it is possible that hackers steal all the information before using mobile phones to "mine" cryptocurrency. People will not only encounter problems such as cell phone stuck, fever and even crash, but also other financial losses

moreover, it is worth noting that some mobile mining apps, in the name of "mining", allow users to invest money and continue to develop offline

4. You can open the task manager to see what program is occupying the CPU, and try to close it to see if it will affect the normal work. In the click on timing plan, see if there is a timing task to start this program. If there is one, it will be removed

5. A virtual currency to solve the problem of distributed storage, similar to IPFs

In the game, we lack the most resources, in fact, is not gold bars, gold bars are important, can be used to unlock home facilities. However, your talent upgrade and career advancement are the major consumption of new currency. Therefore, in order to better pile up various attributes, it is urgent to master the earning method of new currency! Let's share with you some common ways to get new currency to help you earn new currency faster:

I. entrusted tasks in daily copies reward a large number of talents, experience, gold bars, new currency and other materials, which can be said to be a must every day. The method of receiving the entrusted task is to receive it from the task delegation board in the replica. The task is updated at three o'clock every day, and each map can complete four tasks a day

for example, the Commission Board of autumn forest is on the right side of each cabin, while in the map of shashibao, the Commission Board appears near the exit of each cave. If you complete these tasks every day, you can quickly upgrade and earn new coins at the same time

1. Monster output

the monster output mentioned here includes three categories. One category is the infected person who appears on every map. If they die, they may drop the blood of the infected person. If this item is sold at the merchant, you can get s $100 (a blood of S $100). However, as it is a green material, it needs to consume the number of map consignments, so it is a good choice to reasonably arrange the consignments of this article to earn new coins steadily every day

the second type is the mercenaries in shashibao and Yuanxing city. These mercenaries carry a certain amount of new coins, and if they swipe a large amount of new coins, they are also very considerable. The ordinary mercenary is S $50, and the armored mercenary carries S $100. But the attack power of these mercenaries is not bad, and some will appear in groups, so we must be careful

the third category is various monsters in the camp, such as lumberjack, wolf, bear, wild boar, etc., which will drop certain items. These items can not only be used to start territorial missions, but also be used to sell. Oh, a S $50

2. Treasure map

you can also obtain a large number of new coins and certain materials by opening the treasure map. There are two ways to obtain the treasure map. One is the daily treasure map task. For example, if you find the Explorer Wald in the autumn forest, you may get a treasure map. Another is the Explorer Wald in Yuanxing City, who can find the big secret treasure task to receive Yuanxing city, Mark the location of the treasure map on the map. The location of the treasure map may appear in some dangerous areas of the map, and the opening of the map has timeliness, which needs more attention

another way to get the treasure map is to brush the stronghold battle, and exchange the meritorious deeds obtained into the treasure map. This treasure map can be opened to obtain S $300 and some materials. Fortunately, it can proce rare materials such as formula fragments and polymer coating. Many friends say that they can't find the location of the NPC in the stronghold campaign. You can click the daily on the top right and click the location mark in the stronghold campaign to show it on the map

Third, special NPC tasks are similar to what I said before. There will be a new currency reward for submitting task items. There are also some NPC tasks such as photographers who can collect film photos every day and get a new currency reward after completing them. Specifically speaking, you can only find different "Landscapes" by browsing more on the map

4. Special treasure chest

in addition to some conventional treasure chest, there are many special treasure chest on the map, such as the treasure chest of the exploration interface. There are more or less such treasure chest in each map. After opening, you can get new coins and special materials

of course, besides exploring treasure chest, is there any special treasure chest? The answer is yes. For example, the adventurer's treasure chest in shashibao (the name is probably this) will open with a plot and reward you with S $1000, plastic, screws and other resources. All these need to be explored carefully

Five, boss kill

boss kill reward, there are a large number of new coins, in addition to the daily unknown biological activities to deal with the mutant infected, there are two hidden small boss, I have said before, in the far Star City of Pingle warehouse location 6 boss, and located in the lower left corner of the autumn forest severe infection area 15 boss, kill will get new currency reward oh

big God link:

7. 1. Security, each website has the responsibility to protect user privacy
2. User's personal information is private and will not be displayed publicly after authentication
3. In order to prevent users from registering their accounts maliciously, many websites require users to register with their real names
4. Real name authentication is also to protect users and rece the infringement of users by lawbreakers.

8. If you use your smartphone to browse pornographic websites, you have a higher risk than watching pornographic websites on your computer! Because you is too laggy to see short URL to determine whether it will be your target website, but one thing is for sure. Pornographic websites are always the source of malware, and 1, mobile phone suddenly becomes very stuck. Mobile phone is too laggy rather baffling to monitor the mobile phone. Because some surveillance viruses will occupy a part of the mobile phone's memory, making the phone very stuck. In particular, some mobile phone cleaning methods have been tried, such as restarting the mobile phone, restoring the factory settings of the mobile phone and so on, which are useless, so the mobile phone is very likely to be monitored
2. The cost of mobile communication has increased greatly. It's clear that you haven't made several calls, but the communication cost has been increasing. This situation is likely that your mobile phone has been monitored by others, because when you make or answer a call, the mobile phone will secretly send the information to the monitor
3. Mobile phone traffic suddenly increases. After the mobile phone is monitored by others, the information in the mobile phone, such as contacts, documents, etc., will be sent to the monitor in the form of network data, and the traffic data generated will naturally be counted on your mobile phone, so the sudden increase of mobile phone traffic is also likely to indicate that your mobile phone is monitored by others
4. The mobile phone suddenly comes out with some strange things. For example, some contacts you don't know appear on your mobile phone, some running programs you haven't installed are running, and so on. All kinds of signs may indicate that your mobile phone has been monitored by others
5. The power of the mobile phone suddenly decreases ring the call. After the mobile phone is monitored, the monitoring virus will force your call recording to be transmitted to the monitor. In the process of transmission, the voice quality of the call will change, which will generally become very small, just like when you call in a place with bad signal
in addition, mobile phones occasionally fail; The key response of mobile phone is very slow; Mobile phone SIM card inexplicably opened the three party call function, and so on, are likely to show that your mobile phone has been monitored by others
but we don't need to worry too much. After all, we are not important people, and we don't have a lot of money. No one will deliberately take risks to monitor us, such as restarting the mobile phone, restoring the factory settings of the mobile phone and so on. So the mobile phone is likely to be monitored

2. It's clear that you haven't made several calls, but the communication cost has been increasing. This situation is likely that your mobile phone has been monitored by others, because when you make or answer a call, the mobile phone will secretly send the information to the monitor

3. After the mobile phone is monitored by others, the information in the mobile phone, such as contacts, documents, etc., will be sent to the monitor in the form of network data, and the traffic data generated will naturally be counted on your mobile phone, so the sudden increase of mobile phone traffic is also likely to indicate that your mobile phone is monitored by others.
