Bitcoin phishing encryption

1. You can install a computer manager on the computer
and then open the toolbox to see a file decryption function
after using this function, the encrypted computer files can be automatically released

2.

If bitcoin accounts are decentralized, so are hackers. Bitcoin, which uses blockchain technology, is not more secure than bank accounts. On the contrary, it is vulnerable to hackers. So, in the world of virtual currency, how to protect the security of account funds

Secret your private key address

the bitcoin address is the only information needed to define the distribution and transmission end of bitcoin. These addresses are generated anonymously by the user's wallet. Once the address is used, all the transaction history related to it will destroy the confidentiality of the address. Anyone can view the balance and all transactions at any address. Because users usually need to disclose their identity in order to receive services or goods, the bitcoin address cannot be completely anonymous. For these reasons, it is better to use bitcoin address only once, and users must be careful not to disclose the address

When replacing the computer, try to destroy the hard disk of the original computer. Don't save or publish the private key of bitcoin to the cloud, mailbox or collection. If a network administrator writes a regular expression to retrieve the text, he can find all the information and crack the user's account

2. Stored in bitcoin wallet

many bitcoin exchanges have been attacked by hackers. If you use the wallet of bitcoin exchange, please use Google's "double authentication" to ensure security. During the development of virtual currency, there have been many cases of bitcoin exchange running away. The exchange owns the private key of the user's wallet, which is not a safe way to save bitcoin

bitcoin wallet has a wide range of customers, which is more secure than the wallet service of bitcoin exchange. No matter what kind of wallet you choose, you should choose a strong password. Don't use the same password as the registered email. At the same time, do not put eggs in the same basket, choose multiple storage ways to improve the security of assets

using the genuine system of bitcoin wallet, regularly updating security vulnerabilities and fixing bugs can improve security. Some studies have pointed out that IOS system is more secure than Android system, because the existing security vulnerabilities of Android system may be relatively easy to be attacked by hackers

3. The most common way to identify phishing sites is phishing sites. Hackers will create a domain name similar to bitcoin website, which may be sent to users through e-mail and other channels. Once users try to log on the website, hackers will record their login information

so be careful before clicking any link. Many browsers have the service of "phishing check". If you carefully identify the domain name of the website, you can identify the phishing website

4. Guard against Keylogger

in addition to phishing sites, the common attack method of hackers is Keylogger. Keyboarding is the easiest way to capture passwords. The deception of key recording software is very high, even the technical house may believe it. In short, a keyboard recorder is actually a script code. Once it is installed on the operating system of the target computer, it will record all the keystrokes on the keyboard and send them to hackers, mostly through FTP

the successful method of introcing Keylogger depends on many factors, including the operating system, the lifetime of keylogger and the anti infection level of target computer. Keyboard recorder is usually injected through web browser. The security vulnerability of the target machine depends on the type of browser it uses; Whether the operating system installed on the target machine is genuine, and whether the operating system is updated with the latest security vulnerabilities and bug fixes

5. Watch out for USB theft program

the software will retrieve your password and login credentials stored in the browser. Once FUD, some stealing programs can be very powerful. In most cases, a steal program is a. Bat file, which can be injected into the target machine online or driven by USB

6. Using proxy and VPN

proxy server and VPN can increase the security of your bitcoin wallet, although most people mistakenly believe that VPN makes them anonymous online. But in fact, VPN only improves the privacy of users. VPN can rece the possibility of hackers accessing the router to open the port, which also means that they are less likely to succeed

7. Encryption and backup wallet

wallet backup is essential to prevent losses caused by computer failure or human error. If a computer or mobile phone is lost, a backup wallet can help retrieve the bitcoin. At the same time to encrypt the online backup, any backup that can be accessed through the Internet should be encrypted

how to back up your wallet? First, close the bitcoin client, then select the backup wallet of the menu file in the main interface, and the wallet.dat file to other hard disk partition, mobile hard disk or U disk

it should be noted that the entire wallet should be backed up, not just the private key. Bitcoin wallet has many private keys for receiving transaction change. If only the private keys of visible bitcoin addresses are backed up, most of the funds may not be restored from the backup. Also, back up your wallet regularly to make sure that all recent bitcoin change addresses and newly created bitcoin addresses are included in the backup

Cold storage

offline wallet is called "cold storage", which is the safest way to save digital currency

cold storage is an offline wallet that is not connected to the network, that is, it will not be attacked by black horse and Trojan horse. However, because the operation is relatively complex and the price is relatively expensive, the price of offline wallet is more than 1000 yuan, which is suitable for users who have a lot of bitcoin and are ready to hold it for a long time

although the operation of cold storage is relatively complex, it is the safest storage method. At present, only cold storage has truly realized the inviolability of personal assets and is not subject to the supervision of others

3. It's very strange that you ask this question. Why does no one care? Atomic currency is given to users free of charge in China through app registration, playing atomic games, advertising and so on. People have said that China and the United States do not sell it. What's the problem with no sale transaction? Moreover, atomic currency issuers are from foreign countries.

4. According to a new survey released by Walker sands
communications in Chicago, American consumers believe that bitcoin payment is more secure than mobile wallet applications

according to the report, 3% of the 1400 sample consumers think that bitcoin is the safest way to pay, compared with only 1% who think mobile wallet is the safest way to pay< According to the report,

"consumers think that mobile wallet payment applications are unsafe payment methods, even lagging behind the cryptocurrency bitcoin."

among all the payment methods, cash is the most reliable way for these consumers. 56% of the respondents said they like to use cash, while 22% chose credit card and 18% chose debit card

only 2% of the respondents said that they thought check was the most reliable payment method

in addition, the report also found that there is a trend of consumers' payment methods turning to digital payment, which is accelerating with the emergence of mobile payment procts such as apple pay.

5. 1. You can install a computer manager on your computer, and then open the toolbox to find the document Guardian
3. Through this function, there is a file recovery function to recover the files deleted or encrypted by blackmail virus

6. CTB locker, a new form of rogue software, uses despicable means to send a virus email to the victim. Only when the victim opens it, the ward will invade the victim's personal computer and encrypt the victim's specific files (JPEG image is a popular target). If the victim wants to retrieve the files, he must pay a ransom in bitcoin

for people, the best way is to prevent the source of infection, do not open or run the unknown installation package, install a safe prevention attachment - bitcoin house

the best way to remove is to re install a system.

7. Bitcoin system uses asymmetric encryption to improve transaction security. This is what people from Yingfu College of Finance and economics told me. There was a friend there at that time

in the process of information encryption and decryption, different keys are used. Only the corresponding public key can be used for decryption. Owning the private key is equal to owning the ownership of bitcoin

similarly, bitcoin users also need to pass authentication to ensure the ownership of their own cryptocurrency assets.

Note: because I'm not sure whether the mobile client can view the pictures in the answer, so the owner had better use the computer web version

[portal] is a purple vortex. Similar to the portal in world of Warcraft, the portal in Guild Wars 2 is used to transfer players from one area to another. In the main city, you can see the intercity portal. In the largest main city: Lion arch, besides intercity portal, you can also see battlefield portal

the above are the common icons on the map in Guild Wars 2

there are also some icons, for example, one is the same as the icon of the portal, but the color is green. This icon is the progress point of the mainline task. In addition, like a white scroll, there is a star icon on the scroll, which is the messenger. You can only see the messenger in the main city. The messenger's role is to tell you what's going on on the maps around here
