I have been receiving e-mail messages from my e-mail contacts that have no subject and contain a link to a phishing website. This is another attempt by Phishers to trick you into clicking on the link in the e-mail message, because it appears as if it came from someone that you know. But remember, there is a technique called e-mail spoofing, where the sender can change the "from e-mail address", so the e-mail appears as if it came from someone else.
