The mining program was found to be accessing the network
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
antivirus, if you can't kill it, you can check the program with high CPU or GPU occupation and manually delete it. If you can't, you can't change the hard disk (the disk where the mining program is located)... Change the computer
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
there have been many similar pyramid schemes before. They often carry out pyramid schemes under the guise of bitcoin or virtual currency, but they have nothing to do with virtual currency
bitcoin home.com once broke out spark entertainment bitcoin scam and Porter coin scam. Their MLM model is the same, and there is no new idea, the use of our greedy psychology. There is no pie in the sky for no reason.
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.
