Stop mining command
a new customer recently consulted with sine security company, saying that his server often fails to open the website of the card, and the remote connection to the server is extremely slow. Sometimes the Ping value reaches 300-500, and he often switches. After listening to the customer's words,
will generally judge that he has been attacked by CC + DDoS mixed traffic, It's strange to say that there is no traffic attack on the computer room. It's not a traffic attack, but it also causes the server card and website to fail to open. What kind of attack is this? In order to solve the problem of
client server card, we immediately arranged a security engineer to carry out security detection and deployment on his Linux server
{rrrrrrr}
mining Trojan horse is also designed. If the mining process is forced to stop by customers, it will automatically start to continue mining to achieve uninterrupted mining.
careful inspection shows that it is through setting the hourly task plan, remotely downloading shell mining Trojan horse, and then executing, Check whether the current process exists or not. If not, start the Trojan horse to mine
a detailed security inspection was carried out on the client's Linux server. It was found that fortunately, there was no encrypted server data, and the worm was infected with the disease through the security detection and analysis of our security engineers, we found that the server uses Apache Tomcat environment, the open architecture of the platform is JSP + Oracle database, and Apache Tomcat uses the version of 2016, which leads to the serious remote command execution vulnerability of Apache, Through this vulnerability, the intruder can directly invade the server and get the administrator permission of the server,
virus. If the data was encrypted, the loss would be great. The client was a platform, and the client's data was very important. After finding out the mining Trojan horse,
do customers need to know how the server is attacked? Was the Trojan horse uploaded? It can prevent the attack
in the later stage
sine security engineer immediately repairs the Apache vulnerability and clears the Trojan horse. So far, the problem has been solved, the client server
runs stably, and the network station opens normally
1. Open the folder and you will see the minecraft folder, as shown in the figure below
1: can play, but the special effects are not high. in the case of enough processor and memory, gtx750ti (have not seen the 7500ti in the title, the closest should be 750ti) can meet the minimum requirements of the game, that is, gtx560 performance and above, but can not meet the recommended graphics card requirements of the game, gtx770, and the gap is large
2: the system needs to install 64bit version of win7 and win10, the processor performance should at least reach the level of 2nd generation i5, 4th generation I3 and above, have at least four threads, the minimum computer memory should reach 4GB, it is recommended to reach 8GB, and it is better to be equipped with solid state hard disk

secondly, mining requires the computer to be running all the time and can't be turned off, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity.
