Facebook revealed on Friday that it had detected a security breach in which an unknown attacker or attackers managed to gain access to 50 million users’ accounts by exploiting vulnerabilities in its software.
But it wasn’t until a second, follow-up conference call with reporters on Friday that Facebook acknowledged one of the most alarming parts of the incident: not only did the hackers obtain the ability to access the Facebook accounts of the affected users, they also had access to other services to which people have connected their Facebook accounts, like Tinder, Spotify, and Airbnb.
It also turns out that Instagram, which is owned by Facebook, may also have been affected by this recent security breach. If you used your affected Facebook account to log into your Instagram account, hackers would have been able to access that account as well, reported Mashable.
Facebook repeatedly insisted both in its official statement and on the conference call that the investigation is still in its early stages and they are still finding out whether these accounts were misused or not.
Facebook CEO Mark Zuckerberg, and COO Sheryl Sandberg, the company’s top two high-profile accounts, were also among the accounts affected.
