Facebook Bug Lets Hackers Delete Friends

swandives writes "There's lot of talk about Facebook and privacy at the moment, but a bug in Facebook's website lets hackers delete Facebook friends without permission. Steven Abbagnaro, a student from Marist College in Poughkeepsie, New York, reported the flaw, writing proof-of-concept code that scrapes publicly available data from users' Facebook pages and deletes all of their friends, one by one. The victim first has to click on a malicious link while logged into Facebook. Abbagnaro's code exploits the same underlying flaw that was first reported by Alert Logic security analyst M.J. Keith who discovered a cross-site request forgery bug, where the website doesn't properly check code sent by users' browsers to ensure that they were authorized to make changes on the site."

Social networking sucks

I deleted my Facebook account a week or so ago, and I was, at the time, hoping that diaspora would end up being something besides vaporware. After a week without it, though, I find myself pleased with my lack of knowledge about what people I didn't like in high school had for dinner.
