According to Nulltx, the Twitter and Instagram accounts of social giant Facebook were both hacked earlier this week. The same attacks also hit HBO, NFL, and The New York Times. Facebook and Messenger are victims. But how these accounts were stolen and why they were affected at the same time is unknown. Twitter quickly blocked the accounts and sought to return them to the owner. For Libra, a cryptocurrency project that has faced many obstacles, this incident has undoubtedly brought more hidden concerns.
