On Jan 4th, we saw a dump of 2 Million cards onto the black market – one of the largest single day drops we’ve seen in a while. While we can’t definitively say what the source of the breach was, the percentage of Extremely High Value cards is significantly higher than we see on average. These are cards like the Amex Centurion card – an invite-only card that comes with a $7500 setup fee, and $2500 annual fee. While it is hard to determine from a single black market, this would indicate these could come from a high end source, such as Neiman Marcus.
Easy Solutions offers black-market monitoring as part of our Detect Monitoring Service (DMS) to provide our customers with early warning of massive credit/debit card breaches that are driven by POS malware (like the Target breach was). Any data that is collected via malware on POS terminals will quickly end up on the black market. Black-market monitoring can mitigate losses, and also serve as an indicator that a severe infection is going on. By proactively monitoring for indicators of compromise, institutions can take additional steps to shutdown threats before they result in system wide compromise.
