Security Issue, Wifi Passwords Are Not Encrypted In Ubuntu Systems

Dear ubuntu user,

This article is very important for you! Did you know that wifi passwords are not encrypted on Ubuntu systems? They are stored in clear text in a folder outside the home folder so they are accessible for unwanted users.

This issue has been reported and a Canonical developer has explained in the mailing lists how to fix it. Are you guys curious to know what causes this issue?

This issue is caused by the fact that 'Available To All Users' option is enabled by default. You can easily disable this option from the graphical user interface and everything will be fixed.

1. Go to the network indicator.

2. Click on Edit Connections.

3. Go to Wireless.

  1. Hi,

    on my Xubuntu machine the files I think you refer to (/etc/NetworkManager/system-connections/) have all the 600 permissions even while all connections are made available to all users.
    But nonetheless thanks for the hint.

    Best regards
