When reinstalling MacOS High Sierra, setting root user password I have noticed strange line `dsl-201-101-1-179-sta:` before my admin username `user$`.

I Googled and found references to WannaCry ransomware, for instance [this](https://www.vmray.com/analyses/wannacry-ransomware/report/user-sequential-behavior.html). Other references showed IP with Mexican DSL provider `dsl-201-100-226-146-sta.prod-empresarial.com.mx`.

I am really not sure how it came to be but it does not matter how many times I reinstall my Mac. After a while this comes up in my terminal.  I have never used Windows on this computer and it was wiped securely through disk utility before fresh install many times.
