In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120
How to effectively prevent the harm of mining viruses to the computer?
Some terminals or servers are passively mined due to infection with mining Trojans. The main reason is the accidental download of virus-containing software and the implantation of mining Trojans because of high-risk vulnerabilities such as weak passwords in the device. So how can we deal with and prevent this virus? First, we need to understand the definition of cryptocurrency mining.
Definition of cryptocurrency mining
Cryptocurrency mining uses computer equipment resources (such as hash rate, network bandwidth, hard disk storage, etc.) to solve complex mathematical operations, thereby generating decentralized cryptocurrencies based on blockchain technology. Coins and Ethereum are the main ones, and cryptocurrencies can be bought and sold through the trading market, thereby obtaining many capital gains.
I. The harm of cryptocurrency mining to computers
Direct harm
1. The host performs high-performance computing for a long time, wastes network bandwidth, occupies high CPU and memory, and cannot process normal user requests or tasks in time.
2. Increase power consumption and speed up computer CPU, memory, and other hardware aging speed.
Potential hazard
1. Hackers steal confidential information through mining programs, such as confidential documents, user names, passwords of crucial assets, etc., resulting in further losses to campus IT assets.
2. Hackers control the host as a broiler to attack other units on the Internet, violating the network security law.
3. Hackers use the already controlled machines as a springboard to continue infiltrating the business system area, resulting in more severe network security attacks.
II. The way to find the virus
1. Look at the process. In general, the process has a high CPU usage during mining operations. You can check the current operating process to see if there is a process with high CPU usage.
2. Check the security log. If the virus did not clean up the logs, traces could be found in some security logs. Find the abnormal login IP through the security log, and continue to search for viruses.
3. View historical commands. The history command might have some clues if it wasn't deleted. Find and download samples through the history command and execute the sample instructions.
4. Check the timing script. If you need to start the mining virus regularly, there will be some information in the timing script to check. First, find the virus by searching the timer crontab.
III. Disposal of mining viruses
1. Professional anti-virus software is installed on the computer, and an emergency check is performed on the terminal to verify whether the terminal is infected with a mining virus. The virus is checked by scanning the anti-virus software.
2. Some mining is found on the webpage. When the user visits the website linked to the horse, it is loaded into the browser for mining. When the browser is closed, the mining disappears, and the mining program will not stay on the original disk. Virus-checking tools cannot kill it. However, you can use TCP monitoring network software to check who is communicating with the mining pool server marked by the platform. After analysis, conduct killing and forensics, and then conduct targeted killing.
3. If you can't kill it, you can directly reinstall the system.
IV. Preventive measures
1. Install antivirus software
Install antivirus software, update the virus database, and perform antivirus.
2. Avoid weak passwords
Avoid weak passwords and avoid using the same password on multiple systems.
3. Close the application service
Turn off unnecessary services such as Windows Sharing Services, Remote Desktop Control, etc.
4. Application installation
Do not install unfamiliar and risky apps; try to download apps from regular app stores.
5. Raise awareness of cybersecurity
Do not use storage devices such as U disks and mobile hard disks of unknown origin.
Do not click on emails and attachments from unknown sources.
Do not download cracked software from unknown sources.
Do not access the public network and do not allow the internal network to access external network devices of unknown origin.
Epilogue
Finally, remind everyone when mining. Be sure to pay attention to these potential dangers to avoid unnecessary losses.
