“Dropbox users themselves may be the source of security problems. If you are sharing a folder with 100 users, a couple of them are bound to be using easily guessed passwords to guard their accounts (the names of pets or first-born children, 'password', etc.). Sharing links can also lead to problems, if the wrong link is shared or someone posts the link online or in some other public forum.” Computer SecurityDropboxDropbox Quotes Book:Dropbox In 30 Minutes Source: Dropbox In 30 Minutes
