p. 71 Symantec Corporation Internet Security Threat Report 2013 :: Volume 18 ThREAT ACTIVITy TRENDS Analysis of Malicious Web Activity by Attack Toolkits Background The increasing pervasiveness of Web browser applications, along with increasingly common, easily exploited Web browser application security vulnerabilities, has resulted in the widespread growth of Web-based threats. Attackers wanting to take advantage of client-side vulnerabilities no longer need to actively compromise specific networks to gain access to those computers. These attacks work by infecting enterprise and consumers that visit mainstream websites hosting Web-attack toolkits, and silently infect them with a variety of malware. Symantec analyzes attack activity to determine which types of attacks and attack toolkits attackers are utilizing. This can provide insight into emerging Web attack trends and may indicate the types of attacks with which attackers are having the most success. Data Figure A.9. Malicious Website Activity: Attack Toolkit Trends, 2012 Source: Symantec 90% 80 70 60 50 40 30 20 10 JAN FEB MAR APR MAY JUN JUL AUG Methodology This metric assesses the top Web-based attack activity grouped by exploit “Web kit” families. These attacks originated from compromised legitimate sites and intentionally malicious sites set up to target Web users in 2012. To determine this, Symantec ranked attack activity by the number of associated incidents associated with each given Web kit. SEP OCT NOV DEC Others Blackhole Sakura Nuclear Redkit Phoenix
