Cash in the aisles: How gift cards are easily exploited

Presented at BSidesLV 2017, July 25, 2017, 6 p.m. (55 minutes).

It is commonly thought that gift cards must be activated to have any monetary value. Often displayed on countertops and lining grocery store aisles, seemingly worthless unactivated gift cards are free for anyone to grab a handful. However, weaker security features than the average credit card makes these gift cards nearly as valuable as cash. Mass produced, their numbers follow a predictable pattern and have limited built-in security, such as a chip or pin, to prevent fraud.
