Over the past week, Facebook users are finding friends they never wanted. The social networking site is dealing with the third attack in two weeks.
Facebook users frequently get requests to join groups from their online friends.
"It happens to me all the time. A friend may want you to try something," said Facebook user Tim Tasker.
But try clicking on that Facebook link that seems to be from a friend and David Greenberg with IUPUI says, "When you log on they are going to capture your password then link you to the real Facebook so the user who logged in doesn't know anything bad had happened."
They don't realize hackers can use now use their web identity to send more malware spam to more victims who think it's from a friend.
Some users discover the problem in time and have sent warning e-mails to friends telling them don't open links that seem to come from their friend.
Opening a link could put all of one's online personal information at risk.
"In general I would say don't click on links to get to Facebook. Open up your own browser and use a bookmark or type in
www.Facebook.com," said Greenberg.
If you get one of those "check it out" type links Greenberg says to "be suspicious. Respond to the person first and say did you send that?"
Bill Noel with Net Heads internet and game café in Carmel says everyone needs to be wary, especially more inexperienced users.
"There is a much older population that is discovering Facebook largely through their children," he said. Noel says older users could be vulnerable because "they may not be as computer savvy or alert to these things and tend to be click happy, so Facebook is fun and new and they don't have their guard up."
Tim Tasker says his young friend had her account hacked. "Nothing too big has been stolen yet. It could have been a lot worse," he said.
