Several high-profile Twitter accounts including that of US presidential candidate Joe Biden, Tesla CEO Elon Musk, Microsoft Co-founder Bill Gates and of Apple were simultaneously hacked on July 15th 2020 by attackers to carry out what appeared to be a cryptocurrency scam. The accounts, along with those of former President Barack Obama, Kanye West, Warren Buffett, Jeff Bezos and Mike Bloomberg, posted similar tweets soliciting donations via Bitcoin to their verified profiles as well.

After this attack, Twitter announced the strengthening of security measures during the investigation of the hacker attack, significantly restricting access to its internal systems. Their blog said “This attack relied on a significant and concerted attempt to mislead certain employees and exploit human vulnerabilities to gain access to our internal systems. This was a striking reminder of how important each person on our team is in protecting our service. We take that responsibility seriously and everyone at Twitter is committed to keeping your information safe.”
