8 Ports Mostly Used by Hackers

Top Ports Hackers Used Techhyme

With the increase in the use of the internet, the security of our digital systems has become a critical concern. As we rely more on technology, cybercriminals have become more sophisticated and are always finding new ways to exploit our systems. One of the ways they do this is by using different ports to gain access to our networks.

Ports are like doors that allow communication between devices on a network. They are essential for the functioning of the internet, but they can also be used maliciously by hackers to gain unauthorized access to a system. In this article, we will look at 8 ports that are commonly used by hackers and the risks associated with them.

  1. Port 21 – File Transfer Protocol(FTP)
  2. Port 22 – Secure Shell(SSH)
  3. Port 23 – Telnet
  4. Port 25 – Simple Mail Transfer Protocol(SMTP)
  5. Port 53 – Domain Name System (DNS)
  6. Port 69 – TFTP
  7. Port 135 – Windows RPC
  8. Port 137-139 – Windows NetBIOS over TCP/IP

Port 21 – File Transfer Protocol (FTP)
FTP is used to transfer files between computers on a network. It is an old protocol that has been around for a long time, and it’s still widely used. Hackers can use it to gain access to a system and steal sensitive data, such as login credentials, personal information, and financial data.

Port 22 – Secure Shell (SSH)
SSH is a secure version of Telnet and is used to remotely access a system. Hackers can use it to gain unauthorized access to a system, steal data, and even take control of the entire network. They can also use it to install malware or spyware on the system.

Port 23 – Telnet
Telnet is an old protocol that was once widely used for remote access to a system. It is not secure, and any data sent over Telnet is transmitted in plain text, making it easy for hackers to intercept and read. They can use Telnet to gain access to a system and steal sensitive data.

Port 25 – Simple Mail Transfer Protocol (SMTP)
SMTP is used to send and receive email. Hackers can use it to send spam and phishing emails to unsuspecting users. They can also use it to gain access to a system by using email as a vector for a malware attack.

Port 53 – Domain Name System (DNS)
DNS is used to resolve domain names to IP addresses. Hackers can use DNS to redirect users to fake websites that look like legitimate ones. They can also use it to launch a DDoS attack, which can bring down a website or an entire network.

Port 69 – TFTP
TFTP is a simplified version of FTP and is used to transfer small files. Hackers can use it to gain access to a system and install malware or spyware.

Port 135 – Windows RPC
Windows Remote Procedure Call (RPC) is used to allow remote access to a Windows system. Hackers can use it to gain access to a system and steal data or install malware.

Port 137-139 – Windows NetBIOS over TCP/IP
NetBIOS over TCP/IP is a protocol used to allow Windows systems to communicate with each other. Hackers can use it to gain access to a system, steal data, or install malware.

In conclusion, ports are essential for the functioning of the internet, but they can also be used maliciously by hackers. To protect your system from these attacks, it is important to keep your software up to date, use a strong password, and be cautious when opening emails or clicking on links.

It is also advisable to use a firewall and an antivirus program to block unauthorized access to your system. By taking these measures, you can reduce the risk of falling victim to a cyber attack.
