The Twitter accounts of Barack Obama, Joe Biden, Bill Gates, Elon Musk, Jeff Bezos, Mike Bloomberg, Kim Kardashian West, Warren Buffett, Kanye West and official accounts of Uber and Apple were among the tens of high-profile accounts that were hijacked on Wednesday. These accounts requested donations in the cryptocurrency through a link.
Twitter said it was a “co-ordinated” attack targeting its employees “with access to internal systems and tools”.
“We know they [the hackers] used this access to take control of many highly-visible (including verified) accounts and Tweet on their behalf,” the company said in a series of tweets.
It added that “significant steps” were taken to limit access to such internal systems and tools while the company’s investigation was ongoing.
Meanwhile, Twitter CEO Jack Dorsey tweeted: “Tough day for us at Twitter. We all feel terrible this happened.”
It is still being investigated if any Twitter employee was behind the spam.
Some leading cryptocurrency sites were also compromised on Wednesday. Cryptocurrency platforms like Coinbase and Gemini falsely “announced” they had partnered up with an organization called CryptoForHealth, through their Twitter accounts. They claimed that the organisation was going to provide people with bitcoin as long as they sent some to an address first.
