Facebook users, watch out for yet another weekend phishing attack. This one involves a video titled something along the lines of "Most Hilarious Video Ever" posted on Facebook walls. Click on it and it directs you to a fake Facebook login page, where it tries to steal passwords (possibly even your home address) and install malware. Check out Websense and Mashable for more details or watch the Websense video in the gallery. (Its safe, promise.)
