Case Study: Leading Retail Bank Prevents Credit Card Fraud with Digital Shadows SearchLight

Bank Discovers Customer Credit Card Numbers Shared And Traded Online

Leading Retail Bank, a financial services customer, faced a data exposure challenge when customer credit card numbers were discovered being shared and traded on IRC channels used by cyber criminals to test card validity and commit fraud. Digital Shadows SearchLight™ was used to monitor for specific IIN/BIN ranges associated with the bank’s cards and identify these risky exposures.

Digital Shadows verified the activity, added context, and delivered the incident to the bank’s SOC Manager within an hour of the original post. The bank quickly disabled the impacted cards, prevented further fraud, and alerted affected customers, enabling a proactive response to fraud risk; Digital Shadows helped the bank detect and contain the issue before it escalated.
