Some common online fraud schemes that you should be aware of include the use of advanced hacking techniques to gain unauthorized access to secure financial systems, the sale of stolen credit card information on the dark web, and the operation of illegal online marketplaces where stolen goods, drugs, and counterfeit products are traded. These activities involve criminal networks and can lead to serious legal consequences if caught. It is important to stay away from such activities and report any suspicious behavior to the appropriate authorities.
