Room-Mates Hacking My Comp?

DigiD

TS Rookie
I live in a house with 6 other people using the same wifi. I have been noticing some strange activity on my linux and Win10 computers. shrared folders, users and groups I dont recognize and other troubling activity.

Is there something I can do to secure my connection even though we all use the same router/wifi?

We live next to a universiry and a couple of the roomates are taking computer enginnering courses, so im fairly confident its someone in this household messing with me

For Windows 10:
  1. net user administrator /active:yes, and press Enter to run it.
  2. be sure to set a NEW password for this account -- see https://www.top-password.com/knowledge/change-windows-10-password.html
  3. Now change YOUR login password
  4. Remove Sharing on all folders where it exists
  5. Then disable File & Print sharing -- see https://www.ricksdailytips.com/turn-off-file-printer-sharing-windows-10/
  6. Disable Remote Desktop -- see https://www.lifewire.com/disable-windows-remote-desktop-153337

For your Linux:
  1. change the root password
  2. change all user account logins

NEVER login to Linux as root. Instead, learn to use "su" or "sudo"
