Exploiting Delay
Ten months of vulnerability · 4 points
01 Slim CD operated for ten months with compromised systems without detecting the intrusion, allowing the company to defer costly security improvements throughout this period. high

03 Customers remained unaware their payment information was vulnerable for nearly a year, preventing them from taking protective action during the actual period of exposure. high
04 The company completed its investigation and identified affected cardholders before sending notifications, creating additional delay between breach discovery and customer awareness. medium
📍

03 Affected individuals now bear the burden of monitoring their financial accounts and protecting against identity theft due to security failures they did not cause and could not prevent. high
04 This breach illustrates the urgent need for stronger data protection regulations that mandate real-time intrusion detection and impose meaningful penalties for extended security failures. high
05 The Slim CD case demonstrates that notification alone is insufficient accountability when companies fail to maintain adequate security for sensitive payment data. medium
