Can use ll/proc/pid/exe pointing to the execution of the file, then check the file content, can find the source file
And kill processes, in addition you can try to see whether the next hour started again, and if so, check the hour the timing of tasks, including the content inside the script, generally this will be regular tasks to automatically start
In addition you baidu under someone else's process, much to learn from it,
