6969 tcp acmsoda BitTorrent tracker

Backdoor.Assasin.D trojan - opens a backdoor on one of the following ports: 5695,6595,6969,27589. Backdoor.Assasin opens port 27589, Backdoor.Assasin.B opens port 6969, Backdoor.Assasin.C opens port 6595, and Backdoor.Assasin.D opens port 5695 to listen for commands from the attacker.

Other trojans that use this port: GateCrasher, IRC 3/IRC Hack, Net Controller, Priority, Danton, 2000Cracks.

Backdoor.Win32.BlueAdept.02.a / Remote Buffer Overflow - the malware listens on TCP port 6969, after connecting to the infected host TCP ports 6970, 6971 are then opened. The newly opened port 6970 is vulnerable allowing third party attackers who can reach an infected host ability to trigger a buffer overflow overwriting EAX, ECX and EDX registers.

Backdoor.Win32.Destrukor.20 / Authentication Bypass - the malware listens on TCP port 6969. However, after sending a specific cmd "rozmiar" the backdoor returns "moznasciagac" in Polish "you can download" and port 21 opens. 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.Destrukor.20 / Unauthenticated Remote Command Execution - the malware listens on TCP port 6969. Third-party adversaries who can reach infected hosts can run commands made available by the backdoor. Remote attackers can read anything the victim types by starting the remote key log command "key_on". Some commands in Polish include "podglad", "dyski", "procesy", "wywiad", "rej_klucze1", "offserver" and many others.

SANS ISC: port 6969

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.
