What is Fullz?
Fullz is a slang term used in the cybercriminal community to describe a comprehensive package of personal identifiable information (PII) and financial details about an individual. This typically includes data such as the victim’s name, address, date of birth, Social Security number (or equivalent), email, phone number, and payment card details (including CVV codes).
The term "fullz" indicates that the information is "full" or complete, making it particularly valuable for fraudsters. Fullz are often used for identity theft, account takeovers, loan fraud, or other financial scams. The availability of fullz on dark web marketplaces and forums poses significant risks to individuals and businesses alike.
