Technical Details

what runs on :1025

There is no standardized Network Blackjack handshake, framing, or default exchange that can be inferred from TCP or UDP 1025. The port may carry any application-specific protocol; on older Windows systems, ports beginning at 1025 could be selected for dynamic RPC endpoints, while other operating systems and applications may use the number as an ephemeral or manually configured port. Traffic is therefore not reliably identifiable by port number alone, and it is unrelated to the fixed RPC endpoint mapper on TCP/UDP 135.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

Exposure risk depends on the process that selected the port. An internet scanner can fingerprint or interact with the service, and a dynamic RPC endpoint or other cleartext application may expose enumeration, authentication, or software vulnerabilities; administrators should identify the owning process and restrict the port rather than allow TCP or UDP 1025 generically.

Record

iana registry entry

port: :1025
service: Network Blackjack
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 4/10caution
category: Gaming
usage: IANA assigns TCP and UDP 1025 to Network Blackjack, but no registrant or widely deployed implementation is documented. In practice, this port is often encountered as an application-selected port, including legacy Windows dynamic RPC allocations, so the listening process must be identified locally.
