Since the Cambridge Analytica data scandal became public in April 2018, Facebook has not come to rest. Already in June the largest social network in the world had to add a new breakdown. Software errors made postings unintentionally to “public”-14 million accounts were affected. However, the last incident with 50 million affected user accounts is significantly more serious. Hackers apparently took advantage of a security gap. The attackers were probably concerned with so-called access token, digital keys, with the help of which the accounts of other users can be taken over.
