PLEASE HELP ME Understand and Resolve below issue:
When I opened Terminal (on aaPanel dashboard), I noticed below message:
Last failed login: Mon Dec 7 15:29:43 UTC 2020 from 185.153.196.230 on ssh:notty
There were 278 failed login attempts since the last successful login.
And sometime, 278 crossed 20K.
Is it hacker's attack? If so, what steps I have to take.
Thanks.
