What is SMB, What is SMB Port Numbers 135 and 445, SMB is a networking protocol that allows systems on a network to share access. This article is all about SMB, how it works and what ports it uses.
SMB Ports are typically used for file sharing. The SMB protocol allows programs and services on networked computers to communicate with each other.
SMB ports can be secure if properly configured and protected, but they have been targeted by various exploits and attacks in the past. Is SMB used today? Yes, SMB is still widely used, especially in Windows environments, with newer versions offering improved performance and security. ...
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.
For example, the SMB protocol is used to share folders, printers, and serial ports within an organization. Due to defects in the protocol design, the SMB protocol is exploited by the zero-day vulnerability called EternalBlue, which leads to the WannaCry outbreak. Disclosure of such services on...

Open ports can be dangerous when the service listening on the port is misconfigured, unpatched,vulnerable to exploits, or has poornetwork securityrules. Of particular danger arewormableports which are open by default on some operating systems, such as the SMB protocol which was exploited by azero...
It is impossible to prevent the act of port scanning. Anyone can select an IP address and scan it for open ports. To protect an enterprise network, security teams should find out what attackers would discover during a port scan of their network by running their own scan. Be aware, however...
