W32.Sasser.Worm [Symantec-2004-050116-1831-99] (2004.04.30) - remote access trojan. Affects all current Windows versions, attemts to exploit a vulnerability addressed in Microsoft Security Bulletin [MS04-011]. There are some issues associated with using the [MS04-011] update discussed here: MS KB 835732.
Trojan runs a FTP server on port 5554 on infected systems and attempts to connect to random IPs on TCP port 445. If a connection is established, the worm sends shellcode to that computer which may cause it to run a remote shell on TCP port 9996. The worm then uses the shell to cause the computer to connect back to the FTP server on port 5554 and retrieve a copy of the worm.
Backdoor.Win32.FTP.Ics / Authentication Bypass - the malware runs an FTP server on TCP port 5554. Third-party attackers who can reach infected systems can logon using any username/password combination. Intruders may then upload executables using ftp PASV, STOR commands, this can result in remote code execution.

Backdoor.Win32.FTP.Ics / Port Bounce Scan (MITM) - the malware listens on TCP port 5554 and accepts any credentials. Third-party intruders who successfully logon can abuse the backdoor FTP server as a man-in-the-middle machine allowing PORT Command bounce scan attacks using Nmap. This vulnerability allows remote attackers to abuse your system and discreetly conduct network port scanning. Victims will then think these scans are originating from the infected system running the afflicted malware FTP Server and not you.

SANS Internet Storm Center: port 5554
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.
