Internet TCP port 4444 is commonly used by the Metasploit Framework, a penetration testing software, for creating a backdoor access point in the target system. It is also used by the Oracle WebCenter Content - Content Server, a digital asset management solution. Additionally, the port is associated with the KRB524 protocol, which is a Kerberos version 5 to version 4 ticket translator. However, it's important to note that these uses are not standard and the port can be used by other applications as well.
TCP port 4444 is commonly associated with the Blaster Worm, which was a notable computer virus in the early 2000s. This worm exploited a vulnerability in Microsoft's Remote Procedure Call (RPC) service, allowing hackers to gain control over the infected system. The worm would open TCP port 4444 and use it as a listening port, creating a backdoor for the attacker. This allowed the attacker to execute commands on the infected system remotely. Additionally, the Metasploit Framework, a popular penetration testing tool, often uses port 4444 for reverse shell connections, which can be exploited by hackers if not properly secured.
