Backdoor.Win32.Jokerdoor / Remote Stack Buffer Overflow - the malware listens on TCP port 4004 and drops an randomly named executables E.g. acrorqwjlle.exe etc. Third party attackers who can reach an infected system can send a junk 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".

A vulnerability has been identified in Opcenter Quality (All versions), SIMATIC PCS neo (All versions < V4.1), SINUMERIK Integrate RunMyHMI /Automotive (All versions), Totally Integrated Automation Portal (TIA Portal) V14 (All versions), Totally Integrated Automation Portal (TIA Portal) V15.1 (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions < V17 Update 7), Totally Integrated Automation Portal (TIA Portal) V18 (All versions < V18 Update 3). The affected application contains an improper input validation vulnerability that could allow an attacker to bring the service into a Denial-of-Service state by sending a specifically crafted message to 4004/tcp. The corresponding service is auto-restarted after the crash is detected by a watchdog.

The affected application contains an out of bounds write past the end of an allocated buffer when handling specific requests on port 4002/tcp and 4004/tcp. This could allow an attacker to crash the application. The corresponding service is auto-restarted after the crash.

SANS Internet Storm Center: port 4004
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.
