Linux intrusion mining
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
Yes
please refer to the following tutorial:

Yes, why not. Moreover, it is easy to operate and has the following advantages:
< UL >it is more stable and easy to maintain
the cost of system resources is small (that is, the hardware requirements are not high), and the mining cost is saved
the installation and debugging are simple, and the technical threshold is lower
full open source system, free legal edition, more stable and further save mining cost? In fact, you only need two steps to mine under Linux system:
open the website, enter the mobile phone number, select how many CPUs you want to use to mine, the default is to use 50% of the CPU to mine, click to generate your exclusive command and
is such a simple operation
open the website, enter the mobile phone number, select how many CPU you want to use to mine, the default is to use 50% of the CPU for mining, click to generate your exclusive command and
enter the console paste command, and click Run
is such a simple operation.
If you only need two steps in Linux system, you can mine under Linux system:
< UL >open the website, enter the mobile phone number, select how many CPUs you want to use to mine, the default is to use 50% of the CPU to mine, click to generate your exclusive command and
is such a simple operation
you can download and install a Tencent Royal point
after opening it, you can directly check and kill this kind of computer virus by using the virus checking and killing function in it
