Some of the latest spam messages that posted itself on the walls of Facebook users was reportedly due to a bug on Facebook.
Sean Sullivan, an F-Secure security researcher, said that some clever spammer discovered Facebook’s books vulnerability that allows auto-replicating links.
Facebook said Tuesday that it has fixed the bug and cleaned up users’s wall.
“Earlier this week, we discovered a bug that made it possible for an application to bypass our normal CSRF [cross-site request forgery] protections through a complicated series of steps,” said a company spokesman in a statement. “We … fixed it within hours of discovering it for a short period of time before it was fixed, several applications that violated our policies were able to post content to people’s profiles if those people first clicked on a link to the application.”
The survey scam offering Best Buy and Walmart gift cards is the latest scam to spam user’s wall on Facebook. Last week, Facebook users were spammed with free iPhones, which came close on the hells of another spam offering free iPads to users on Twitter and Facebook.
