More and more fraudsters are harvesting the log-in data of Facebook members in order to impersonate them and ask their friends for money, according to the social-networking company.

The scammers use phishing techniques to trick Facebook members into providing log-in information. For example, fraudsters often send legitimate-looking e-mail messages purporting to be from Facebook that ask members to visit a Web page and enter their log-in credentials. They also post messages on members' profile Walls with links to supposed video clips or photos that really lead to phishing Web sites.

Once scammers can log in to someone's Facebook account, they often engage in what Facebook calls a "419" scam: pretending to be the member, they send messages to the person's friends asking for money.

In a "419" scam, fraudsters usually ask that the money be wired to them using Western Union, saying they're stranded and penniless in a foreign country.
