In this particular case, cyber criminals use Clipboard Hijacker to replace the cryptocurrency wallet addresses that are copied to the clipboard with addresses of other wallets. For example, data copied from a document is stored in the clipboard so that users can then paste it to another, perhaps different, document. The clipboard is a buffer in operating systems used to temporarily store data while it is moved (typically, copied) from one place to another. This malware must be uninstalled immediately. In this way, they use Clipboard Hijacker to steal cryptocurrency from other people who use cryptocurrencies and make associated transactions. This can be achieved simply by changing cryptocurrency wallet addresses from those saved in users' clipboards to others owned by cyber criminals. Clipboard Hijacker is malicious software used by cyber criminals to make fraudulent cryptocurrency transactions.
