There are several ways to collect or obtain valid data (access to payment system and bank accounts, cards data, documents, etc.) from victims:
1. Infect the victim's device with a stealer that will steal all data.
2. Order the hacking of commercial and government databases.
3. Social engineering – call the victim, pose as a bank or insurance company employee, and trick them into giving up all the necessary data.
4. Create a fake company and post ads for tempting job openings. Then ask victims to submit their details to complete an application.
5. Purchase the necessary equipment from trusted sellers (the easiest method).
6. Create a phishing website for a payment system or bank, then spam the current database.
7. Use a trusted "Lookup Data" service.
