Statement: For users, Facebook's revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next? For the owners of the affected accounts, and of another 40 million that Facebook considered at risk, the first order of business may be a simple one: sign back into the app. Facebook logged everyone out of all 90 million accounts in order to reset digital keys the hackers had stolen - keys normally used to keep users logged in, but which could also give outsiders full control of the compromised accounts.  Which of the following points do not capture the negligence of Facebook in the most appropriate manner? Arguments: I. What Facebook knows so far is that hackers got access to the 50 million accounts by exploiting three distinct bugs in Facebook's code that allowed them to steal those digital keys, technically known as ‘access tokens’. The company says it has fixed the bugs.  II. The hack is the latest setback for Facebook during a tumultuous year of security problems and privacy issues . So far, though, none of these issues have significantly shaken the confidence of the company's 2 billion global users.  III. One of the bugs was more than a year old and affected how the ‘View As’ feature interacted with Facebook's video uploading feature for posting ‘happy birthday’ messages. But it wasn't until mid-September that Facebook noticed an uptick in unusual activity, and not until this week that it learned of the attack.
