With Facebook's security and privacy standards under fire from all sides, suffice it to say that this is not a good time for one of the company's investors to fall for a Facebook phishing scam.

On Saturday evening, a Facebook event invitation was sent to some of the over 2,300 friends of Jim Breyer, the Accel Partners venture capitalist who sits on Facebook's board of directors, asking "Would you like a Facebook phone number?" As it turned out, this was a scam: Users who entered their passwords in response to the spoof message from Breyer in turn had the whole thing sent to their friends lists, too.

"This was a phishing scam and Jim's account appears to have been compromised," read a statement from Facebook as provided to venture industry news site PEHub. "The issue has since been resolved and we're actively trying to block this activity."
