Trend Micro: Attacks involving exploit kits fell from 27 million in 2015 to 8.8 million in 2016. Angler, Neutrino and Nuclear, two other popular exploit kits also stopped being actively used in 2016. There were a lesser number of zero-day vulnerabilities in 2016 making exploit kits less lethal than usual. It’s too soon to say whether the decline represents a permanent or temporary shift away from the use of exploit kits to drop malicious payloads. The decline does not necessarily mean exploit kits will not continue to be used in attacks, experts say.”]
