Internet-Security.com TCP port 70 details

TCP port 70 is used by the Gopher protocol.
Real Gopher servers include UMN gopherd (original), Gophernicus, Bucktooth, Motsognir, and Pygopherd; for example, Floodgap’s public Gopher server (gopher.floodgap.com:70) runs Bucktooth and hosts the Veronica-2 search service over port 70.
Other public Gopher servers at universities and hobbyist sites also serve content on port 70 using these daemons.
Clients that access port 70 include Lynx, curl (and libcurl), and browser add-ons like OverbiteWX/OverbiteNX.
Many Linux/BSD distributions still package these Gopher servers and clients, enabling live deployments on port 70.
Security note: attackers often abuse the gopher:// URL scheme in SSRF exploits to craft raw requests to internal services (e.g., Redis), even though the SSRF payload may target ports other than 70.
