If you use Dropbox, be aware that a security flaw has been discovered which easily allows anyone that has access to your computer to grab the Dropbox configuration file. That would then give them full access to all your Dropbox files, without leaving any traces or signs of your account being hacked.

This flaw was discovered by security expert Derek Newton and was reported on his blog dereknewton.com.

No fix has been issued as of yet, but the company is reportedly looking for ways to tie the config file to your machine in order to secure it.
