Address Search Protocol Daemon (ASPD)
One of the most commonly probed ports used by many trojans.
SubSeven Trojan horse uses this port (TCP). Also used as a backdoor port left behind by exploit scripts, such as those in the Ramen worm. While some scans for this port may be due to SubSeven, others may be looking for a remote shell.
Other trojan horses/backdoors that use this port: Bad Blood, Ramen, Seeker, Ttfloader, Webhead, TheSaint, Lion, EGO.
BackDoor-G [Symantec-2000-121907-4858-99] uses port 27374/tcp.
Backdoor.Win32.Jokerdoor / Weak Hardcoded Credentials - the malware listens on TCP port 27374. The password "mathiasJ" is weak and hardcoded in the PE file. Failed authentication generates a "POPUP incorrect password..." message, using TELNET results in an error "PWDPerror reading password..." Using Nc64.exe utility results in a trailing line feed character "\n" after the supplied password. This causes the cmp statement check to fail even if the password is correct due to the "\n" character.

Backdoor.Win32.Jokerdoor / Remote Stack Buffer Overflow - the malware listens on TCP port 27374. Attackers who can reach an infected system can send a large payload and trigger a classic stack buffer overflow overwriting the ECX, EIP registers and structured exception handler (SEH). When connecting you will get a "connected" server response, then we supply our payload as a parameter prefixed by "DOS".

SANS ISC: port 27374
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.
