According to a recent Facebook’s blog post, Approximately 100 developers connected to Facebook via application program interfaces (APIs) improperly accessed user data. In a blog post, the company has only disclosed that developers were able to access profile pictures and names of the users but they will ensure the deletion of any member data although there is no evidence of abuse.
API is a set of functions that allow applications to use data from their respective platforms. In this case, the platform is Facebook. After the scandal, the Federal Trade Commission fined Facebook for $5 billion and the Company was given instructions on how to handle privacy leaks.
