W32.Reatle.E@mm [Symantec-2005-080215-5809-99] (2005.08.02) - a mass-mailing worm that opens a backdoor and also spreads by exploiting the MS DCOM RPC Vulnerability ([MS03-026]) on port 135/tcp. It uses its own SMTP engine to email itself to gathered email addresses. Opens an FTP server on port 1155/tcp. Opens a proxy server on port 2005/tcp. It also attempts to perform denial of service (DDoS) attack agains known security websites on port 1052/tcp. Note: port 1052 corresponds to the dynamic DNS service.
Duddie, TransScout trojans also use port 2005 (TCP).
Backdoor.Win32.Delf.zs / Unauthenticated Remote Command Execution - Backdoor Delf.zs c0ded By Eb0La, is used to build backdoors that listen on TCP port 2005. Upon building it drops an executable named "[Shell_Me]_Server.exe." The name for the spawned backdoor defaults to "Syst32.exe" but can be customized. Third-party attackers who can reach infected systems can execute arbitrary commands by simply connecting to the backdoor which will return a remote shell to the infected host as no authentication exists.

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.
