Twitter confirms 130 accounts were targeted by hackers
The FBI is now investigating the incident.
Twitter has confirmed that 130 accounts were targeted by hackers in a cyber attack that took place on Wednesday night.
Kanye West, Joe Biden, Kim Kardashian, Barack Obama, Bill Gates, Jeff Bezos and Elon Musk were among those who were successfully targeted by the hackers.
Major companies such as Apple and Uber were also affected by the hack.
Twitter said it is still trying to work out if private data, which could include private direct messages, were stolen or compromised.
The hacked accounts tweeted telling people that they had 30 minutes to send $1,000 in bitcoin in order to be sent back twice as much.
Twitter's support account released a statement following the cyber attack, saying: "We're working with impacted account-owners and will continue to do so over the next several days.
"We are continuing to assess whether non-public data related to these accounts was compromised."
Twitter CEO Jack Dorsey said on Wednesday morning that they were still trying to figure out how it happened, describing it as a "tough day" for everyone working for the social media network.
Twitter temporarily stopped all verified accounts from tweeting in an attempt to deal with the hacking, though that has now been resolved.
The investigation is still ongoing, with the FBI now involved.
