9100/tcp - Prometheus Node exporter.
Prometheus (open-source system monitoring) uses these TCP ports:
9090 (server)
9091 (Pushgateway)
9093 (Alertmanager)
9094 (Alertmanager clustering)
9100-9563 - Prometheus exporters

The default configuration of some HP Printers and HP Digital Sender enables the Remote Firmware Update (RFU) setting, which allows remote attackers to execute arbitrary code by using a session on TCP port 9100 to upload a crafted firmware update.
References: [CVE-2011-4161] [BID-51324]

Kyocera 3830 (aka FS-3830N) printers have a back door that allows remote attackers to read and alter configuration settings via strings that begin with "!R!SIOP0", as demonstrated using (1) a connection to to TCP port 9100 or (2) the UNIX lp command.
References: [CVE-2006-0788] [BID-16685] [SECUNIA-18896] [OSVDB-23245]

HP Laserjet printers with JetDirect cards, when configured with TCP/IP, allow remote attackers to bypass print filters by directly sending PostScript documents to TCP ports 9099 and 9100.
References: [CVE-1999-1062]

On EPSON WF-2750 printers with firmware JP02I2, there is no filtering of print jobs. Remote attackers can send print jobs directly to the printer via TCP port 9100.
References: [CVE-2018-14900]

p910nd on Inteno IOPSYS 2.0 through 4.2.0 allows remote attackers to read, or append data to, arbitrary files via requests on TCP port 9100.
References: [CVE-2018-10123], [EDB-44635]

SANS ISC: port 9100

Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.

TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.

UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.
