  1. 100% All Natural Canadian Malware(much success, such cryptocurrency, wow!) LS Pulsifer Surveillance Analyst 9 April 2014

  2. Outline • EK Overview • The Righteous Client • The Shady Sample • Stages of Infection • IDS Alerting • Post-infection Symptoms • Conclusion

  3. Exploit Kit Overview • Pre-written attacks on specific applications • Served through redirects via trusted sites • Information gathering (plugindetect.js) • To PWN or not to PWN?

  4. The Righteous Client • Windows 7 x86 (32 bit) • Service Pack 1 • User Account Control (UAC) Enabled • Flash 12.something (latest) • Silverlight 5.1.30214 (latest) • Google Chrome 33.something (latest) • <INSERT THE POINT OF FAILURE HERE> • Protected (reactive) by SNORT NIDS • Emerging Threat PRO Rules • Sourcefire VRT Rules

  5. The Shady Sample • malwaredomainlist.com / urlquery.net • Sample is a variation of ShadyRAT • Operation Shady RAT: Actor widely assumed to be the People's Republic of China • http://en.wikipedia.org/wiki/Operation_Shady_RAT

  6. It Begins! Stage 1
