Everything about CC's Fullz

What Are Fullz?

Fullz is a term used by criminals to describe sets of stolen personal information that can be used to impersonate someone or to use their bank cards.

Simply put, fullz are stolen identities or stolen credit card information. 

The word comes from the word “full” in the sense of “full data” or “full credentials” and encompasses all the information a fraudster needs in order to impersonate someone to defraud a company, steal directly from the victim, or conduct illegal activity that will be attributed to the victim if they are caught.  

How Do Fullz Work?

Fullz can be acquired in several ways, including:

Phishing and spear phishing: The victim is convinced they are sharing their passwords and/or other information with a legitimate company they trust.

Bought on the dark web:

Fullz are readily available to buy from other criminals, usually in bulk. Sourced from data breaches and elsewhere.

These long lists will require card testing and other tests to identify which are live fullz. 

Rented out from ID mules:

Fullz can be rented out on a temporary basis.

Card skimming:

Payment fullz can be obtained using devices such as ATM skimmers and other methods of stealing card information.

Account takeover:

Covert takeover of personal email or other accounts.

Physical theft:

By stealing someone’s physical documents or cards – and assuming they do not realize and/or cancel it.

Typically, an ID fullz package contains:

1️⃣The victim’s full name

2️⃣The victim’s address

3️⃣The victim’s date of birth

4️⃣The victim’s social security number (or ID number, passport number, etc.)

5️⃣Other data, e.g. the victim’s email address (and sometimes their password)

6️⃣The total cost of identity theft in 2020 was USD 56bn, per Javelin research, while Security Magazine reports that each fullz record averages USD 8 to purchase.

Meanwhile, a credit card fullz includes:

Cardholder’s name

Billing address

CVV code

Credit card number

Expiry (and issue date where applicable)
