How can malware be used for financial gain?

### REPLY:
Malware can be used for financial gain in various ways. One common method is through the use of keyloggers, which can record keystrokes and capture sensitive information such as login credentials and credit card details. Another method is through ransomware, where the malware encrypts the victim's files and demands a ransom in exchange for the decryption key. Additionally, malware can be used to steal banking information and conduct fraudulent transactions.
