For example, a user may wish to modify traffic destined for the 445/TCP port to 8445/TCP. To overcome this operational hurdle, we have developed a custom utility named “PortBender” which allows us to redirect traffic from an incoming TCP port to an alternative TCP port.

Unfortunately, in previous scenarios, we have been primarily limited to passive credential collection and unable to perform relaying attacks when obtaining credentials through SMB. Furthermore, it is not uncommon for our team to perform name resolution poisoning during red team engagements to harvest credentials within an environment.

Often, we need to perform this attack from a compromised Windows system where the built-in SMB service is already listening on port 445/TCP. Colloquially we often refer to this as a “Computer AdminTo Computer” vulnerability.Įxploiting this issue in practice during a red team engagement has often historically been difficult. Your application can then use the data for further processing or analysis.In a previous article titled “ Active Directory Computer Account SMB Relaying Attack,” we discussed how an attacker could leverage computers assigned administrative rights to other computers to escalate privileges or move laterally using the printer spooler service.

From that point on, all data sent from the locally attached serial device will be redirected to the virtual environment. All you need to do now is to specify the server’s IP address and TCP port to establish connectivity. You can share the locally attached device with the virtual machine by installing COM Port Redirector on the VM and creating a virtual serial port.

You also have a virtual environment on the second computer which can run the required operating system. You also have an application that needs to communicate with the device but is not compatible with the server’s operating system. Finally, let’s look at a situation where you have a device connected to a local computer which is acting as the server.
#Tcp redirector install#
Install the software on your computer and connect to the remote device over the network to achieve full functionality over the peripheral equipment. If there is a device located remotely that supports the Telnet (RFC 2217) protocol, you can work with it as if it is a local device with COM Port Redirector.The functionality will be the same as if they had a physical null-modem cable connection. Then, port redirector technology can be used to create virtual COM ports on both machines and the applications can use them to communicate with each other. The key is that both computers need to be connected to the same local network or the Internet. COM Port Redirector can also be used to establish communication between apps on two machines where employing a null-modem cable is not possible.With the Telnet protocol selected, an app can manage all the remote port settings as if it was physically attached to the device.

The application can use the virtual port created on the target PC to access and interact with the remote peripheral. Both computers need to have COM Port Redirector installed for this to work.
