Hi! I’ve read that there are some guys hijacking computers and lock them with some password encryption. As I understand this can happen on user folder on linux system too, as users can run bad software unintended (trojans).
Shall medias as audio, movies and picture be stored with root write and user read permission or is it not necessary? And especially pictures as they are harder to restore, as audio and movies can be copied from media again, but pictures often are removed from cameras to get more space.
The user folder can easily be deleted and set up a new one by root, and give the hijacker some finger.
I’m no good in protecting my data, have backup of the most importent, but it take time if lost the data on harddrive. :shame:
As long as you do not use root when not strictly needed, you are pretty save.
And of course you should make backups of your data as with any operating system/computer.

Hi
On windows you mean the crypto locker trojan. It can happen on windows
systems, but if they are connected to a linux based network share then
yes those files will be encrypted. On a stand-alone linux system no way
the software can run (maybe wine, if it’s lucky)… So the moral of
the story, backup backup backup… on separate media and also store
off-site.

Nasty thing… they say the original one is not active, but there are
others.

I don’t believe that this particular malware runs on Linux, but you can’t be too careful (and I don’t think that they can make the ‘ransomware’ element work on Linux, but I haven’t really kept up to date with it).
- Backups
- Keep your system up to date
- Get all your software from trusted sources
- Don’t do silly things when you get unsolicited files from across the internet
That’s probably all that you need to do to stay reasonably safe as a normal user. Absolute safety is more difficult, though - see how paranoid three letter agencies get.
lol!OK! Sounds wounderful. Use openSUSE as my main system, but only know the most importen thing, oS sounds better and better for every forumpost I read. Thanks for the calming information.
