High-profile Twitter accounts swept up in wave of apparent hacking

A series of high-profile Twitteraccounts 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, billionaire Elon Musk, and rapper Kanye West, among many others - used to solicit digital currency."This appears to be the worst hack of a major social media platform yet," said Dmitri Alperovitch, who co-founded cybersecurity company CrowdStrike.
