To assess the scope of the adware problem for enterprises, Cisco threat researchers examined 80 different adware variants. About 130 organizations across verticals were included in our investigation, which took place from November 2015 to November 2016.

Figure 13 shows the types of incidents we observed in the organizations included in our investigation. Ad injectors were the primary source of infections. This finding indicates that most of these unwanted applications target web browsers. We have also seen an increase in browser-based infections during the last few years, which suggests adversaries are finding success with this strategy for compromising users.
