Abstract
possible vulnerabilities. In this paper we present, and empirically validate, a
novel and more realistic attacker model. The intuition of our model is that an
attacker will optimally choose whether to act and weaponize a new
vulnerability, or keep using existing toolkits if there are enough vulnerable
users. The model predicts that attackers may i) exploit only one vulnerability
per software version, ii) include only vulnerabilities with low attack
complexity, and iii) be slow at introducing new vulnerabilities into their
arsenal. We empirically test these predictions by conducting a natural
experiment on attack data collected against more than one million real systems
from Symantec's WINE platform. Our analysis shows that mass attackers' fixed
costs are indeed significant and that substantial efficiency gains can be made
by individuals and organizations by accounting for this effect.
