Overview
Spearphishing simulation is a targeted social engineering attack vector used by red teams to gain initial access. Unlike broad phishing campaigns, spearphishing uses OSINT-derived intelligence to craft highly personalized messages targeting specific individuals. This skill covers developing pretexts, building payloads, setting up email infrastructure, executing the campaign, and tracking results.
When to Use
When conducting security assessments that involve conducting spearphishing simulation campaign
When following incident response procedures for related security events
When performing scheduled security testing or auditing activities
When validating security controls through hands-on testing
Prerequisites
Familiarity with red teaming concepts and tools
Access to a test or lab environment for safe execution
Python 3.8+ with required dependencies installed
Appropriate authorization for any testing activities
Objectives
Develop convincing pretexts tailored to specific target personnel
Create weaponized payloads that bypass email security controls
Set up email delivery infrastructure with proper SPF/DKIM/DMARC configuration
Execute phishing campaigns with real-time tracking and metrics
Document results for engagement reporting and security awareness improvement
