USB Drive and Remote Copying


I have a somewhat standard USB flash drive that I store files on. Although the files are not particularly sensitive, I am wondering if its possible for a malicious user to remotely copy the files if I decide to leave the USB drive connected while online?

Is there a way to prevent remote copying files from the drive?

It might help if you provide more details.

How would someone be connecting remotely? (SSH, VNC, etc)
How are you mounting your flash drive? (auto-mounting, pmount, sudo mount, mount via fstab, etc)


Hope this helps!

I am not aware of VNC or SSH being active, so I'm not sure how someone would connect remotely. How would I check for remote connectivity software on the system? I mount the USB drive after a prompt pops up (auto with user permissions I suspect). Would it be better to mount the drive in another manner?

As far as I know, there isn't a VNC server installed by default on any distro that I'm aware of. Some distros, however, have an SSH server running by default. What distro are you using?

It seems like you're using it as a standard desktop/laptop and nobody is logging in remotely. If this is the case, then you shouldn't be worried about your flash drive. If the bad guy is remotely logged in to your computer, then I'd be more concerned about a possible root hack, which would let them do anything they wanted.

Hope this helps!

If you are not permanently connected online, it is unlikely you will get hacked at all.

Wrong! Wrong! Wrong!


All it takes is for the OP to visit a malicious website or open a payload in an e-mail attachment, etc. to have their system exploited.

Well I was thinking the OP was sensible about things of that nature.
Obviously if you just click on everything in sight you will suffer sooner or later.

I never make assumptions, especially with the OPs request is generalised and vague.

Well let me put it another way - I've been using computers since 1999 & have not been hacked.

I recently these problems:

1. After logging in as root on another volume, I was unable to unmount (had to reboot to unmount)
2. USB drive suddenly required my root password to mount it. Again, a reboot was required
3. Mouse pointer gets stuck after several minutes of use. Unplugging USB or Reboot required as a temp solution

A Reboot temporarily fixes all problems above.

Still not absolutly sure of the cause, though.

Does the above seem like the result of not using a user password, or could it be services?
