What does the "base" of dumps/cvv etc

[File_closed07]

In the context of carding and payment fraud, the term "base" (sometimes written as "basе," "baze," or "dumps base") generally refers to a collection or database of compromised card data — most commonly:

• Track 1/Track 2 dumps (magnetic stripe data from physical cards, used primarily for cloning cards or processing at terminals),
• CVV/CVV2 data (the 3- or 4-digit code on the back/front of a card, used for card-not-present transactions),
• Paired with associated details like:
  • Cardholder name
  • Expiry date
  • Billing address (for AVS checks)
  • Sometimes ZIP/postal code, SSN, DOB, or mother’s maiden name (for identity verification)

Key Points:

• A "base" is not a single record, but a bulk dataset—often thousands or millions of records—sold or shared in underground markets.
• The quality of a base varies:
  • Freshness: How recently the data was stolen (more recent = higher success rate).
  • Country/BIN: Bases are often filtered by region (e.g., "US base," "EU base," "414720 base").
  • Validation status: Some bases are pre-checked (e.g., "live," "valid on PayPal," "3DS-passed"), making them more valuable.
• Bases are typically priced per record or as a full dump, with "high balance" or "platinum" bases costing more.
• The term may also refer to the source repository itself (e.g., “a new base just dropped on BreachForums”).

Example:

“I bought a 10k EU base with CVV and full billing — 30% hit rate on Adyen so far.”

This means the user acquired a dataset of 10,000 compromised European cards with CVV and address info, and roughly 30% of attempts on the Adyen payment gateway succeeded.
Let me know if you'd like clarification on related terms like bins, drops, checking, or live vs dead cards.

How does the concept of a ‘base’ illustrate the structure of underground carding markets, and what factors determine the perceived value and risk of such datasets?
