Use system monitoring tools: You can use top, htop and other tools that come with the system or third-party monitoring tools to check the CPU, memory, network and other resource usage of the system. If abnormal usage is found, there may be mining viruses.
-
View process information: use the ps command to view the process information of the system, find abnormal processes, and end these processes with the kill command. Mining viruses usually masquerade as the name of a legitimate process, and further analysis is required to confirm whether there is a mining virus.
-
Check the network connection: Use the netstat command or other network monitoring tools to check the network connection of the system, find abnormal connections, and prohibit these connections through tools such as iptables. Mining viruses usually establish connections with remote servers and upload mining results.
-
Check the system log: Check the system log files, such as /var/log/messages and other files, find abnormal log information, and analyze the log files to confirm whether there is a mining virus.
-
Virus scanning: You can use virus scanning tools under Linux, such as ClamAV ( ClamAV deployment method ) to scan the entire system to find out whether there are mining viruses.
To discover and remove mining viruses in a timely manner, it is necessary to monitor the operation of the system frequently, detect abnormalities in time, and analyze and troubleshoot by combining various methods.
