**Executive Summary:** This report analyzes 2015 malvertising-driven exploit kit activity (Angler, Nuclear, Magnitude, RIG), outlining the three-stage infection chain (delivery, landing, payload), advanced evasion techniques (302-cushioning, domain shadowing, anti-VM/anti-analysis), common payloads (Bedep adfraud and multiple ransomware families such as CryptoWall/Teslacrypt), example IOCs and landing-page/URI patterns, and recommends patching browser plugins and using click-to-play to mitigate risk.
