Additional Recommendations:

• Monitor subnet 176.65.132.0/24 for correlated activity
• Consider blocking entire /24 subnet given 68% abuse density
• Review 176.65.132.17, 176.65.132.24, and 176.65.132.129 (all risk score 80)
• Implement continuous monitoring for VMHeaven infrastructure

Analyst Note: While individual IP 176.65.132.50 shows no direct threat indicators, the high-abuse subnet context warrants defensive positioning. The lack of open services suggests this may be a dormant or residential endpoint, but proximity to 26 threat-sibling IPs elevates the operational risk profile.
