Stephanie SandovalTwitter is investigating after a series of high-profile users were hacked in an apparent Bitcoin scam on Wednesday.
On Twitter, the social media company said it was aware of a "security incident impacting accounts" and that it was taking steps to fix it. It also said some users may be unable to tweet or reset their passwords while it was investigating.
The hacks impacted politicians, tech moguls and big companies, including Joe Biden, Amazon CEO Jeff Bezos and Tesla CEO Elon Musk. Kanye West and Kim Kardashian West were also hacked.
Most of the tweets looked similar to this one that popped up on West's page. They read: "I am giving back to the community. All bitcoin sent to my address will be given back doubled."
It's still unclear who's behind the hack.
