UK BUSINESS INSIDER – Oct 1 – Facebook got hacked, it revealed on Friday – and 50M users' accounts were compromised. If the victims logged into other services like Tinder, Instagram, or Spotify with their Facebook accounts, those might be affected to. It's not clear whether the attackers did this, but the possibility may force companies that rely on Facebook's login system to launch their own investigations. Facebook CEO Mark Zuckerberg was among the 50M affected users. The attackers found a way to trick Facebook into issuing them "access tokens" – digital keys – that let them access other users' accounts as if they were that user. After spotting some unusual activity earlier this month, Facebook realized what was going on on Tuesday and subsequently revoked these access tokens before disclosing the hack publicly on Friday.
