Re: Filezilla's silent caching of user's credentials

If the encryption key stays on the same PC, there is absolutely no security
in that. Given that this is open source, security through obscurity can't
even start working (-> encrypting local files with a local key / using
custom algo == security through obscurity).

I think it ought to stay plaintext and people limit access to this file
whenever possible.
It's hardly a trivial matter to delete this file....if an attacker can
search for and read this file, a user could search for the same file and
delete it.

Fortunately, for the poor souls out there that allow read access to their
drives, computer forensics haven't caught up yet (and probably won't in the
near future).

My 2 cents.

Chris.

The issue is that someone gained access to that file.  You sharing your

they MD5'd it?  It sounds like your issue is that your password is
stored.  I mean, they moved your encrypted password from passwd to
shadow for a reason, but that doesn't change the fact that it's stored
and if someone doesn't need access to shadow or passwd, they shouldn't
have it.

Stop logging into your FTP server from a public terminal with Filezilla.

Rubbish.

The passwords should be encoded so-as to avoid trivial searching. End
of story. It takes 10 minutes to do from a development point of view,
and there is no excuse.
