By Habiba Rashid Google's Threat Analysis Group (TAG) labeled the spyware campaign as limited but highly targeted. This is a post from HackRead.com Read the original post: Google reveals spyware attack on Android, iOS, and Chrome

A number of zero-day vulnerabilities that were addressed last year were exploited by commercial spyware vendors to target Android and iOS devices, Google's Threat Analysis Group (TAG) has revealed. The two distinct campaigns were both limited and highly targeted, taking advantage of the patch gap between the release of a fix and when it was actually deployed on the targeted devices. "These
