INTELLIGENT ENTERPRISE SECURITY After finance threat actors turning to healthcare Bulk theft of medical records is a relatively new cyber trend and the pricing model is still to get established in the underground market. F inancial data, such as payment card information, has many established markets. The going price for a single record of information, full package of an individual’s identifying information, with names, social security numbers, birth dates, and account numbers — ranges between $14 to more than $25 per record. Less established sellers have low introductory prices. Intel Security has recently seen around $20 per record for small-scale purchases. Wholesale prices can be even lower, as low as $3 per card sold in bulk. Medical records, on the other hand, appear to be highly variable and range from a fraction of a cent to $2.42 per record. This price is a significantly lower than individual payment card prices but only slightly less than wholesale card prices. Do these prices mean medical data is not worth as much as financial data? Perhaps, but the markets are different. Some sellers have taken advantage of parallel markets to increase their profits. On the underground market forum AlphaBay, the user Oldgollum sold 40,000 medical records for $500 but specifically removed the financial data, which was sold separately. Oldgollum is essentially double-dipping to get the most from both markets. Financial data can also be sold in individual records or in bulk. Medical data appears to be sold only in bulk at this time, which reduces the per-record price to something near the wholesale prices of cards. Certainly, medical data adds value to the transaction. The sellers aim to ensure they extract maximum profit from both markets and do not expect to sell at a premium to either side. 40 Financial data is not the only type of data Intel Security can use to compare market dynamics. Take, for example, two recent social media account dumps, both selling in bulk between 65 million and 167 million accounts, but also gaining only fractions of a penny per record. Even more recent leaks involving Bitcoin forums have similar per-record pricing. Our findings on medical data exceed this amount but do not yet sell at the rate of established markets such as payment cards. The stolen medical data still appears to be taking shape, but the current ecosystem already has a higher per-record value than in markets of non-financial account data.
