The US Federal Bureau of Investigation, the FBI, is investigating a Twitter account hack.

The FBI San Francisco branch says it has launched an investigation into the case of hacking celebrities' Twitter accounts and demanding cryptocurrency.

The FBI says it appears to have been doing this to scam cryptocurrency so far, and said it is advising not to be victims of the post.

Those who are thought to be hackers earlier sent double-bits to the Twitter accounts of politicians, billionaires, and celebrities such as former Vice President of the Democratic Party candidate Joe Biden, former President Barack Obama, Tesla CEO Elon Musk, model Kim Kardashian, etc. 'I'll give it back'.
