Internet-Security.com TCP port 95 details

Port 95/TCP is assigned to the SUPDUP remote terminal protocol.
It was used on DEC PDP-10 systems, notably MIT’s ITS and DEC TOPS-20, where SUPDUP servers accepted interactive terminal sessions on TCP 95.
BSD UNIX distributions (e.g., 4.3BSD and 4.4BSD) shipped a supdup client (and support utilities) to connect to those hosts on port 95.
Historical and legacy hosts run by universities and museums have exposed SUPDUP on this port (for example, public TOPS-20 systems formerly operated by Living Computers: Museum + Labs).
In modern networks it is rarely used outside retrocomputing or preserved academic systems; mainstream software does not rely on TCP 95.
No widely documented malware family is specifically associated with exploiting port 95.
