A common method of fraud is the imitation of an official Twitter channel of one of the larger crypto exchanges. Since Twitter is rarely used to communicate by the official support, the scammers identify people who comment on the tweets. Then these users are connected with the Twitter Messenger and the fraudsters claim that they come from the official service. They ask to have a chat and navigate the users to copied webpages. They ask for credentials, funds or just to log in and grap their passwords.
Only use channels that are published on the official website.
