The Facebook app Sendible has been compromised in a major way, according to reports. Coca-Cola, YouTube, South Park, Google and others are now sending out a malicious link to all of their followers that reads “Change Your Facebook Background Here!” Facebook has finally responded in full: We began removing the posts immediately upon discovering them and shortly after they were made, we immediately began work to fix it. It’s now been resolved, and these posts can no longer be made. We’re not aware of any cases in which the bug was used maliciously.
