- 11 June 2026: Operator score "Basic" (0.39), route stability confirmed.
- 2 June 2026: DNS resolution attempts with mixed success (some failed connections).
- Trend: No persistent malicious activity detected; risk score stable.
---
**Network Relationships**
- Linked Entities:
- Domain: `tor-exit.sg.localenby.is` (DNS PTR record).
- Organization: Linode (same ASN).
- Services: SSH (OpenSSH 9.2), HTTP/HTTPS (no banners).
- Certificates:
- TLS certificate issued to `www.6banyfjrpo.com` (self-signed, no SANs).
---
**Subnet Neighbors**
- Subnet: 172.104.186.0/24
- Neighbor Risk:
- 2 IPs with low risk (25/100 score).
- Subnet abuse density: 0.6667 (mostly clean, but some risk).
---
**Actionable Insights**
1. Monitor Traffic:
- Track outbound traffic from this Tor exit node for C2 or data exfiltration.
- Check for DNS leaks or unintended connections to `localenby.is`.
2. Blocklist Consideration:
- Add to DNS-layer filters due to blacklisted status.
3. Verify Ownership:
- Linodeβs abuse contact is available; confirm if this IP is compromised.
4. Subnet Review:
- While neighbors are low-risk, the subnetβs moderate abuse density warrants closer scrutiny.
Conclusion: This IP is a Tor exit node with mixed risk factors. While not immediately malicious, its association with Tor and DNS blacklists makes it a potential vector for covert activities. SOC teams should prioritize monitoring and verify ownership to mitigate risks.
