- Blacklist activity persists across multiple observation windows
- Subnet context (50% abuse density, 7 threat siblings) warrants monitoring of adjacent IP addresses
- No direct campaign correlation detected
- Cloud infrastructure hosting environment increases potential for legitimate use alongside abuse cases
Recommendation: Block at perimeter firewall; monitor for continued blacklist activity. Evaluate sibling IPs for potential lateral threat indicators.
