Facebook caught exposing millions of user credentials

Facebook has leaked access to millions of users' photographs, profiles and other personal information because of a years-old bug that overrides individual privacy settings, researchers from Symantec said.

Facebook over the years has regularly been criticized for compromising the security of its users, which now number more than 500 million. The company has rolled out improvements, such as always-on web encryption, although users still must be savvy enough to turn it on themselves, since the SSL feature isn't enabled by default.
