TCP 4145
Synopsis
- TCP port 4145 is widely used in the wild for SOCKS proxy services (especially SOCKS5).
- Popular proxy servers such as Dante (Inferno Nettverk), 3proxy, and Microsocks are frequently configured to listen on 4145 for SOCKS5; many publicly listed open proxies advertise SOCKS5 on 4145.
- Scanning platforms (e.g., Shodan) commonly identify 4145/tcp hosts as SOCKS5 proxies due to their prevalence on this port.
- Veritas Volume Replicator (VVR) uses TCP 4145 for its control service (IANA service name: vvr-control) in Veritas InfoScale/Storage Foundation deployments.
- Associated with hacking/exploitation: attackers often expose or hijack SOCKS5 services on 4145 to build proxy networks used for anonymity, spam, credential stuffing, and pivoting within compromised environments.
