so, the company was Vastaamo. was because it got bankrupt after the breach, and GDPR violations.

you can read about how terrible the company's security was here: https://tietosuoja.fi/en/-/administrative-fine-imposed-on-psychotherapy-centre-vastaamo-for-data-protection-violationsor watch mental outlaw's video on the matter, or the Wikipedia article on the breach.
now there are several things that shouldn't have happened (e.g.: don't do these things on your main OS, have root access disabled, etc.), but I'll leave that to you experts.
I'm always worried when making .tars that I'm doing something wrong when the file also has a . file inside. I know this is probably nothing but it makes me think of something like this.
. and .. are how terminals navigate around file systems.
The command
cd .means "change directory (cd) to here (.)"cd ..means "change directory to here, but one level up: my parent directory."So following that model, winrar and maybe older versions of 7zip used folders called '.' as navigational tools within the archive browser. If you double-clicked through them, you'd see where they go.
I don't know how much of this you knew, but the point is it shouldn't freak you out too see them.
