Top Exploit Kit Activity Roundup

This report from Zscaler ThreatLabZ analyzes spring 2016 activity of three major exploit kits—Angler, RIG, and Neutrino—detailing their distribution (malvertising, compromised sites, EITest gates), execution techniques (JS obfuscation, IFrame injections, AV/sandbox checks), geographic hit patterns, and observed payloads (CryptXXX, TeslaCrypt, Qbot, Gamarue, Tofsee, Panda Banker). It highlights Angler's rapid decline in mid-June 2016 with Neutrino and RIG filling the gap, provides visual telemetry (hits and heatmaps), and recommends blocking untrusted third-party scripts and suspicious ads as mitigations.
