Fullz use cases
This data is used by cybercriminals to impersonate someone either when performing an even larger scam or to apply for a loan or credit card in their name.
Where fullz come from
Data gathered from various leaks and data breaches is compiled into these information packages and then usually sold on the dark web. Hacker forums operate like marketplaces, where the price for someone’s identity depends on the accuracy and viability of the information.
