Threat Indicators:

• NOT a Tor exit node
• NOT a known attacker
• NOT a confirmed spam source
• 50+ threat pulses detected across multiple sources
• Route stability: False (0 route changes in last 30 days)

---

## Temporal Analysis

Recent observation history reveals:

• 2026-06-22 19:02: Threat signals observed (pulse_count: 50)
• 2026-06-18 22:52: Minimal operator score (0.1304)
• 2026-06-17 15:02: Minimal operator score (0.1304)

The IP exhibits threat persistence with multiple signal observations within a 5-day window, indicating sustained malicious activity.

## Subnet and Neighborhood Analysis

Subnet: 159.223.146.0/24

• Abuse Density: 0% (clean classification)
• Total Siblings: 1
• Active Siblings: 1
• Threat Siblings: 0

The IP operates within a relatively clean subnet environment. No neighboring IPs in the immediate /24 block show elevated threat indicators. However, this does not mitigate the risk posed by the target IP itself.

---

## Network Relationships

All relationship indicators point to:

• Same Network: DO-13 (DigitalOcean internal network identifier)
• No hostname associations
• No certificate relationships
• No organizational links beyond cloud provider

---

## Recommended Defensive Actions

Priority: Block

Based on the moderate risk profile and observed threat signals, the following firewall rules are recommended:

## Intelligence Narrative

The target IP 159.223.146.187 presents a moderate-to-high threat profile despite operating within a clean subnet environment. The DigitalOcean cloud hosting provides no inherent trust, and the IP has been flagged by multiple threat intelligence sources with 50+ threat pulses. DNSBL listings confirm the IP's association with malicious activity.

The absence of open services suggests the IP may be:

• A compromised server awaiting exploitation
• A source of outbound malicious traffic
• A command-and-control endpoint
• A staging point for future attacks

Action Required: SOC teams should block this IP at the perimeter firewall and monitor for any inbound connections. The IP's cloud hosting nature means it may represent a compromised tenant environment rather than direct attacker infrastructure.
