TCP Services
Standard endpoints
- Predictable, banner-mimic responses for common TCP traffic.
- Session timing captured; payloads retained privately.
- Only protocol-correct talk-back; no scans or outreach.
Passive only · Aggregated & anonymized statistics
We run private research nodes for TCP and UDP services on the open internet.
Nodes accept whatever arrives—tunnels, mail, commodity services, and background noise. We only talk back when protocol completion requires it (e.g., P2P tracker replies, mail handshakes). Intake is stored and reported as aggregated, anonymized data for research and defensive analysis.
What this is
Controlled endpoints that quietly collect unsolicited traffic for protocol research and abuse mapping. No active scanning, probing, or outbound sequencing is performed from these nodes.
Surfaces we expose
Static services with predictable, boring behavior.
Passive intake
UDP Services
Lightweight endpoints
- Minimal responders focused on query logging and timing.
- Malformed packets preserved for offline review.
- No amplification behaviors enabled.
Mail & Tunneling
Message sinks & tunnels
- Mail/messages accepted and acked to sink; no third-party delivery.
- Tunnels constrained to packet capture only.
- Descriptors issued upon clearance if required.
Collection policy
Aggregation
Anonymized statistics only
Outputs are rolled-up counts, timings, and protocol summaries. Raw captures remain internal.
Posture
Passive and non-persistent
Nodes accept inbound traffic and respond minimally for protocol completion. No scanning, seeding, or outbound probing.
Access
By request, with scope
Provide ASN/use case and desired surfaces. Approved requests receive a static summary drop.
Operating memo
These nodes are maintained for protocol research, threat intelligence enrichment, and defender training. Services emulate ordinary endpoints to avoid undue attention while preserving inbound artifacts for later analysis. Data is never used to initiate new communication back to origin sources beyond required protocol completion.
