Biden, Musk and Gates' twitter accounts hijacked

A series of high-profile Twitter accounts were hijacked on Wednesday, with some of the platform's top voices - including U.S. presidential candidate Joe Biden, reality television show star Kim Kardashian, former U.S. President Barack Obama, and billionaire Elon Musk, among many others - used to solicit digital currency.

One of the now deleted tweets read quote: "I am giving back to the community. All Bitcoin sent to the address below will be sent back doubled. If you send $1,000, I will send back $2,000. Only doing this for 30 minutes."

Rapper Kanye West, and Amazon founder Jeff Bezos were among the other victims.

The cause of the breach was not immediately clear.

Shares of Twitter tumbled nearly 4 percent in trading after the market close.

Twitter said in an email that it was looking into the matter.
