The trade of PII is often facilitated on hidden marketplaces, sometimes accessible only through specific anonymity networks. In these forums, cybercriminals buy and sell data packages that typically include a victim's name, address, date of birth, and Social Security number, often supplemented with financial details like credit card numbers or bank account credentials. The aggregation of this data allows for a higher "value" than single pieces of information because it enables more comprehensive forms of fraud. With a complete profile, a criminal can bypass basic security verification checks, opening the door to bank fraud, tax fraud, and the creation of synthetic identities.
