BIN Check

BIN Check (Bank Identification Number Monitoring)

AttackMetricx includes a powerful BIN Check capability under the Identifiers module, designed to detect and monitor exposure of Bank Identification Numbers (BINs) across the dark web and underground markets.

A BIN refers to the first 6 digits of a credit or debit card, which identify the issuing bank and card type. Once exposed on the dark web, BIN data becomes a valuable asset for fraudsters, enabling them to craft fake cards, launch payment fraud campaigns, or conduct identity theft at scale.

How to Add a BIN for Monitoring

1. Navigate to the Identifiers → BIN Check.

2. Add a New BIN → Analysts can register a BIN by entering:

• The first 6 digits of the card.

• The issuing bank’s name.

Once added, AttackMetricx continuously monitors underground forums, marketplaces, and dump sites for any appearance of the registered BINs.

If detected, the system generates a real-time alert and links it to the associated financial institution, enabling rapid response and fraud prevention.

Why It Matters – Strategic Value

• Early Fraud Detection → Identifies compromised card batches before large-scale fraud is attempted.

• Dark Web Correlation → Tracks frequency, sources, and context of BIN exposure across multiple underground ecosystems.

• Regulatory & Compliance Readiness → Supports PCI DSS and financial industry requirements for monitoring cardholder data.

Example Use Case

Suppose the BIN 421873 belonging to Cystack Bank is added to the system. Within days, AttackMetricx detects its circulation on a darknet credit card shop along with hundreds of matching CVVs.

Immediately, the SOC team receives an alert with:

• Exposure source (forum/shop).

• Volume of compromised cards.

• Contextual risk scoring.

This allows the bank to proactively block cards, notify affected customers, and prevent millions in potential fraud losses.
