# Implementing Email Sandboxing with Proofpoint ## Overview Email sandboxing detonates suspicious attachments and URLs in isolated environments to detect zero-day malware and evasive phishing payloads. Proofpoint Targeted Attack Protection (TAP) is an industry-leading solution that uses multi-stage sandboxing, URL rewriting, and predictive analysis. This skill covers configuring Proofpoint TAP, integrating with email flow, analyzing sandbox reports, and tuning detection policies. ## When to Use - When deploying or configuring implementing email sandboxing with proofpoint capabilities in your environment - When establishing security controls aligned to compliance requirements - When building or improving security architecture for this domain - When conducting security assessments that require this implementation ## Prerequisites - Proofpoint Email Protection license with TAP add-on - Admin access to Proofpoint admin console - Understanding of email delivery architecture (MX records, mail flow rules) - SIEM integration capability ## Key Concepts ### Proofpoint TAP Capabilities 1. **Attachment sandboxing**: Detonates files in virtual machines (Windows, macOS, Android) 2. **URL Defense**: Rewrites URLs, detonates at time-of-click 3. **Threat Intelligence**: Proofpoint's NexusAI threat intelligence integration 4. **TAP Dashboard**: Real-time visibility into threats targeting the organization 5. **Campaign correlation**: Groups related attacks into campaigns 6. **Very Attacked People (VAP)**: Identifies most-targeted individuals ### Sandbox Evasion Techniques Detected - Delayed execution (time-bomb malware) - VM detection bypass - User interaction requirements (click-to-enable macros) - Sandbox-aware malware that checks for analysis environment - Encrypted/password-protected attachments - Multi-stage payloads with delayed C2 retrieval ## Workflow ### Step 1: Configure TAP in Proofpoint - Enable TAP for inbound email policy - Configure sandbox profiles (attachment types to detonate) - Set URL Defense rewriting policy - Configure quarantine actions for malicious verdicts ### Step 2: Tune Attachment Policies ``` Recommended attachment policy: - Detonate: .exe, .dll, .scr, .doc(m), .xls(m), .ppt(m), .pdf, .zip, .rar, .7z, .iso - Block without detonation: .bat, .cmd, .ps1, .vbs, .js, .wsf, .hta - Password-protected archives: Attempt common passwords, then quarantine - Dynamic delivery: Deliver email body, hold attachment until verdict ``` ### Step 3: Configure URL Defense - Enable URL rewriting for all inbound email - Set time-of-click detonation - Block access to malicious URLs - Show warning page for suspicious (not confirmed malicious) URLs - Configure allowed domains bypass list ### Step 4: Set Up TAP Dashboard Monitoring - Configure daily threat digest emails to security team - Set up real-time alerts for targeted attacks - Monitor VAP report for high-risk users - Review campaign clusters for coordinated attacks ### Step 5: Integrate with SIEM - Configure syslog/API export to SIEM - Create correlation rules for TAP alerts - Set up automated response workflows ## Tools & Resources - **Proofpoint TAP**: https://www.proofpoint.com/us/products/advanced-threat-protection - **Proofpoint TAP Dashboard**: https://threatinsight.proofpoint.com/ - **Proofpoint API**: https://help.proofpoint.com/Threat_Insight_Dashboard/API_Documentation - **Proofpoint Community**: https://community.proofpoint.com/ ## Validation - Attachment detonation catches EICAR test file and macro-enabled document - URL Defense rewrites and blocks known phishing URLs - TAP Dashboard displays threat summary - SIEM receives and alerts on TAP events
