What are the most common online fraud schemes to be aware of?

### REPLY:
The most lucrative online fraud schemes involve hacking into financial institutions' databases to access users' personal information, credit card details, and login credentials. This information can then be used to carry out large-scale identity theft, credit card fraud, and money laundering operations. These schemes often involve collaboration with organized crime syndicates and can generate millions of dollars in illicit profits.
