Register today to hear FireEye Mandiant Threat Intelligence experts discuss the latest in vulnerability threats, trends and recommendations in our upcoming April 30 webinar. Sourcing Note: Some vulnerabilities and zero-days were identified based on FireEye research, Mandiant breach investigation findings, and other technical collections. This paper also references vulnerabilities and zero-days discussed in open sources including Google Project Zero's zero-day "In the Wild" Spreadsheet. While we believe these sources are reliable as used in this paper, we do not vouch for the complete findings of those sources. Due to the ongoing discovery of past incidents, we expect that this research will remain dynamic.
