Since the Cambridge Analytica data scandal became public in April 2018, Facebook has not been able to calm down. The world's largest social network had to admit to a new glitch in June. Due to software errors, user postings were unintentionally made “public” – 14 million accounts were affected. However, the last incident with 50 million user accounts affected is much more serious. Hackers had apparently taken advantage of a security hole. The attackers were probably after so-called access tokens, digital keys that can be used to take over other users' accounts.
