"Facebook's Twitter account was briefly hijacked by the hacking collective OurMine on Friday afternoon, but the company still appeared to retain some control over the account.
"Hi, we are O u r M i n e. Well, even Facebook is hackable but at least their security better than Twitter. to improve your accounts security Contact us: contact@o u r m i n e .org For security services visit: o u r m i n e. org," a Friday afternoon tweet announcing the takeover said.
The Twitter account belonging to Facebook Messenger was similarly compromised at the same time.
But Facebook still appeared to have some control over the account, and deleted the tweet — posted at least five times — within seconds. Within 30 minutes, the hack appeared to stop."
