This alert for Habbo Hotel's young users is actually a heads-up for everyone on the social Web. Users need to be alert about the "tools" they download to enhance their pages. Bloggernews.net mentions an alert from WebSense computer security firm specifically about "Trojan" keylogger software buried in one of those tools for Habbo users and links to a screenshot of the message. The keylogger software gathers Habbo account users' log-in info in order break in and steal the "Coins" stored in those accounts. Habbo Coins are worth real money (see this page at Habbo.com).
