The simple economics of an external shock to a bug bounty platform

Abstract

Abstract We first provide background on the “nuts and bolts” of a bug bounty platform: a two-sided marketplace that connects firms and individual security researchers (“ethical” hackers) to facilitate the discovery of software vulnerabilities. Researchers get acknowledged for valid submissions, but only the first submission of a distinct vulnerability is rewarded money in this tournament-like setting. We then empirically examine the effect of an exogenous external shock (COVID-19) on Bugcrowd, one of the leading platforms. The shock presumably reduced the opportunity set for many security researchers who might have lost their jobs or been placed on a leave of absence. We show that the exogenous shock led to a huge rightward shift in the supply curve and increased the number of submissions and new researchers on the platform. During the COVID period, there was a significant growth in duplicate (already known) valid submissions, leading to a lower probability of winning a monetary reward. The supply increase resulted in a significant decline in the equilibrium price of valid submissions, mostly due to this duplicate submission supply-side effect. The results suggest that had there been a larger increase in the number of firms and bug bounty programs on the platform, many more unique software vulnerabilities could have been discovered.
