Port 445 is one of several Microsoft Networking ports that are used today as well as in the older versions of Windows. They were used well with theNetBIOSservices in the older versions. Whereas in the newer versions, it is used for direct TCP/IP without the help of NetBIOS. You May Al...
TCP 445: Introduced with the direct hosting of SMB over TCP/IP, this port bypasses the NetBIOS layer. Port 445 is used for direct SMB communication without the need for NetBIOS, making it the primary port for file sharing and access to remote printers and for inter-process communication amo...
For instance, on Windows, SMB can run directly over TCP/IP without the need for NetBIOS over TCP/IP. This will use, as you point out, port 445. On other systems, you’ll find services and applications using port 139. This means that SMB is running with NetBIOS over TCP/IP. Maliciou...

An SMB port is a network port commonly used for file sharing that is susceptible to an exploit known as EternalBlue exploit that resulted in WannaCry.
Discover the basics around SMB protocol, port 445 and 139 and differences. Read about whether SMB is secure and how to protect against dangerous attacks.

more critical. A network monitoring solution should be able to detect activity indicative ofransomware attacksvia insecure protocols. Take WannaCry, for example, where attackers actively scanned for networks with TCP port 445 open, and then used a vulnerability in SMBv1 to access network file ...
TCP port 465 is used for mail servers, such asSMTP. TCP port 53 and UDP port 53 are used for DNS. What is port scanning and what is it used for? A port scan is a series of messages sent by someone to learn which computer network services a given computer provides. ...
primarily uses tcp port 445. in some cases, it might also use ports 137, 138, and 139 if netbios over tcp/ip is enabled. these ports facilitate the communication required for file and printer sharing across networks. ensuring these ports are open and properly configured in your firewall ...
