What uses TCP port 12345?

What uses TCP port 12345?

Port 12345 is best known as the default of NetBus, a Trojan developed years ago, that allows a hacker to access data and gain control over some functions on a remote computer system. More recently, it has been associated with Trend Micro’s OfficeScan anti-virus product, which also uses, or listens on, port 12345.

What does it mean when a TCP port is filtered?

Filtered means that a firewall, filter, or other network obstacle is blocking the port so that Nmap cannot tell whether it is open or closed. Closed ports have no application listening on them, though they could open up at any time.

Why do you get open filtered from Nmap on some scans?

open|filtered : Nmap places ports in this state when it is unable to determine whether a port is open or filtered. This occurs for scan types in which open ports give no response. The lack of response could also mean that a packet filter dropped the probe or any response it elicited.

How do I enable TCP IP ports?

Can you exploit a filtered port?

tl;dr No, you won’t be able to directly exploit this vulnerability through a filtered port, and it can’t be detected in this way. There must be something else going on in your scenario.

Why are my ports filtered?

A filter port indicates that a firewall, filter, or other network issue is blocking the port. Some standard services that can create a filter port can be, but not limited to, a server or network firewall, router, or security device. A common tool that is used to check the status of ports is Nmap.

What does Tcpwrapped mean Nmap?

When Nmap labels something tcpwrapped , it means that the behavior of the port is consistent with one that is protected by tcpwrapper. Specifically, it means that a full TCP handshake was completed, but the remote host closed the connection without receiving any data.

What is Nmap used for?

Using Nmap Nmap allows you to scan your network and discover not only everything connected to it, but also a wide variety of information about what’s connected, what services each host is operating, and so on. It allows a large number of scanning techniques, such as UDP, TCP connect (), TCP SYN (half-open), and FTP.

What is a TCP port used for?

TCP is one of the two main ways to transmit data in a TCP/IP network. UDP, which is a best-effort connectionless protocol, is the other one. For devices to communicate via TCP, they use TCP ports. Generally, a TCP port represents an application or service-specific endpoint identifier.

How do I open TCP IP ports in Windows 10?

Open firewall ports in Windows 10

1. Navigate to Control Panel, System and Security and Windows Firewall.
2. Select Advanced settings and highlight Inbound Rules in the left pane.
3. Right click Inbound Rules and select New Rule.
4. Add the port you need to open and click Next.

How can I tell if a port is filtered?

The only way to find out what is doing the filtering is to know what ‘machines’ are between you and the remote target. Once you know the machines between you and the target, you investigate the configuration of each to find out if it is filtering and if so how.

What ports should be blocked?

For example, the SANS Institute recommends blocking outbound traffic that uses the following ports:

• MS RPC – TCP & UDP port 135.
• NetBIOS/IP – TCP & UDP ports 137-139.
• SMB/IP – TCP port 445.
• Trivial File Transfer Protocol (TFTP) – UDP port 69.
• Syslog – UDP port 514.

What is the port number for TCP 12345?

PORT 12345 – Information. Port Number: 12345. TCP / UDP: TCP. Delivery: Yes. Protocol / Name: [Malware known as icmp_pipe.c] Port Description: [malware info: icmp_pipe.c]

Why is UDP port 12345 flagged as a virus?

UDP port 12345 would not have guaranteed communication in the same way as TCP. Because protocol TCP port 12345 was flagged as a virus (colored red) does not mean that a virus is using port 12345, but that a Trojan or Virus has used this port in the past to communicate.

What is port 12345 in Windows Mobile App?

We do our best to correct any errors and welcome feedback! The port 12345 is also used by the Windows Mobile App “Ambient Color” for controlling ambient lights via network. It is sending a multicast message to group 234.5.6.7. on the port 12345 for setting the RGB-values of ambi lights.
