Trojans that use this port: 711 trojan (Seven Eleven), Ini-Killer, Net Administrator (NeTadmin), Phase Zero, Stealth Spy
Stack-based buffer overflow in WellinTech KingView 6.53 allows remote attackers to execute arbitrary code via a crafted packet to TCP port 555.
References: [CVE-2012-1830]
Siklu EtherHaul could allow a remote attacker to execute arbitrary commands on the system. By connecting to port 555 via telnet, an attacker could exploit this vulnerability to execute arbitrary commands on the system and obtain sensitive information.
References: [CVE-2017-7318], [XFDB-122267]
Backdoor.Win32.Phase.11 / Unauthenticated Remote Command Execution - the phAse zero server v1.1 by njord of kr0me corp listens on TCP port 555. Third-party attackers who can reach an infected system can run commands made available by the malware and execute arbitrary programs further compromising the host. Using telnet to connect worked best, to start programs you need to pass an "S" argument preceding the program name like... EXEC S PROGRAM_NAME. Other commands are CURDIR, SHOWMSG etc. The ftpd command can also be initiated to third-party FTP servers to download tools to the infected host.

SANS Internet Storm Center: port 555
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.
