Malware Pandemic? Sometimes getting a shot only treats the symptoms and not the cause… Dan Lukas – Sr. System Engineer Steve Zervos – Territory Manager
Changing Threat Landscape – Advanced Persistent Threats (APTs) The New Threat Landscape There is a new breed of attacks that are advanced, zero-day, and targeted MODERN Advanced Persistent Threats LEGACY
High Profile Targeted Attacks • 3 minutes • On average, malware activities take place once every 3 minutes • 184 countries, 41% • Over the past year, FireEye captured callbacks to 184 countries, a 41% rise • 46% • Asia (China, Korea, India, Japan, Hong Kong) accounts for 24% callbacks • Eastern Europe (Russia, Poland, Romania, Ukraine, Kazakhstan, Latvia) accounts for 22% • Technology companies • Technology companies experienced highest rate of callback activity • 89% • 89% of callback activities linked with APT tools made in China or Chinese hacker groups Source: FireEye Advanced Threat Report, March 2013

What’s causing the compromise? Dynamic, Polymorphic Malware Coordinated Persistent Threat Actors NEW THREAT LANDSCAPE Multi-Vector Attacks Multi-Staged Attacks
The Attack Life Cycle – Multiple Stages Compromised Web server, or Web 2.0 site 1 Callback Server Exploitation of system 1 4 Malware executable download 2 Exploit detection is critical All subsequent stages can be hidden or obfuscated Callbacks and control established 3 File Share 2 IPS 5 Data exfiltration 4 File Share 1 2 3 Malware spreads laterally 5

FireEye Platform: Multi-Vector Virtual Execution (MVX) Email MPS 4 2 1 3 6 5 CMS MVX SMTP Inbound Outbound HTTP Callback Server 1 – Email with weaponized pdf 2 – Executed in MVX (Email MPS) – phish suspected 3 – Web MPS notified via CMS 4 – Callback over HTTP to C&C server 5 – Callback detected by Web MPS and blocked 6 – End user defended from multi-vector attack Web MPS Multi-vector blended attack
FireEye Platform: Multi-Flow Virtual Execution • File-oriented sandboxing can be easily evadedby malware • Lack of virtually executing flows vs. file-based approach • Lack of capturing and analyzing flows across multiple vectors • FireEye uses multi-vector, multi-flow analysis to understand the full context of today’s cyber attacks • Stateful attack analysis shows the entire attack life cycle • Enables FireEye to disrupt each stage and neutralize attack Infection Server Callback Server Malware Executable DataExfiltration Exploit Callbacks Downloads

Sandbox Approach (Cloud) File-oriented sandbox - evasion 1. Thousands of Permutations(files, OS, browser, apps) 2. Multi-flow analysis 3. Multi-vector analysis 4. Correlation of information 5. Cloud Sharing 6. Time to protection Single file • Sandbox in the cloud • Privacy violation • Compliance and regulation violation • Latency issues Single vector partial hours or days
Sandbox Approach (On-Premises) File-oriented sandbox 1. Thousands of Permutations(files, OS, browser, apps) 2. Multi-flow analysis 3. Multi-vector analysis 4. Correlation of information 5. Cloud Sharing 6. Time to protection • Sandbox (On-Premises) • Malware can easily circumvent generic sandbox • File-based sandbox misses the exploit detection phase • No flow causes lack of stateful malware analysis Single file Single vector Hashes: limited value Non-realtime
