The 2020 Twitter bitcoin scam was a large-scale hacking of Twitter accounts that started on July 15, 2020 at around 20:00 UTC.[1] A number of Twitter accounts, each with millions of followers, were apparently compromised to promote a bitcoin scam.[2] The scam asked individuals to send bitcoin currency to a specific cryptocurrency wallet, with the promise that money sent would be doubled and returned.[3] Based on sources speaking to Vice and TechCrunch, the perpetrators had gained access to Twitter's administrative tools so that they could alter the accounts themselves and post the tweets directly, with the access gained either possibly through paying off Twitter employees to use the tool, or from a compromised employee's account to access the tool directly.[4][5]
