A security engineer has been hired to design a device that will enable the exfiltration of data from within a well-defended network perimeter during an authorized test.
The device must bypass all firewalls and NIDS in place, as well as allow for the upload of commands from a centralized command and control server
The total cost of the device must be kept to a minimum in case the device is discovered during an assessment.

The security engineer has been hired to design a device that can exfiltrate data from a well-defended network perimeter during an authorized test. The device must bypass all firewalls and NIDS in place, as well as allow for the upload of commands from a centralized command and control server. Additionally, the cost of the device must be kept to a minimum in case it is discovered during the assessment.
Given these requirements, the engineer needs to choose a tool that can accomplish the task with minimal cost and maximum efficiency. Let's look at the four options provided and evaluate their suitability for the task:
A. Custom firmware with rotating key generation: This option involves custom firmware that generates rotating keys to bypass firewalls and NIDS. While this may be a viable solution, it is likely to be expensive and time-consuming to develop. Additionally, it may be easily detected by sophisticated security measures.
B. Automatic MITM proxy: This option involves an automatic Man-in-the-Middle (MITM) proxy, which intercepts traffic between the command and control server and the exfiltration device. This tool can bypass firewalls and NIDS and may be less expensive than the custom firmware option. However, it may be more complex to set up and could be detected by advanced security measures.
C. TCP beacon broadcast software: This option involves TCP beacon broadcast software that can send messages to a command and control server without being detected by firewalls and NIDS. This tool is likely to be less expensive than the custom firmware option, and it may be less complex to set up than the MITM proxy. However, it may be more easily detected by sophisticated security measures.
D. Reverse shell endpoint listener: This option involves a reverse shell endpoint listener that can receive commands from a command and control server and execute them on the exfiltration device. This tool can bypass firewalls and NIDS and may be less expensive than the custom firmware option. Additionally, it may be less complex to set up than the MITM proxy. However, it may be more easily detected by advanced security measures.
In conclusion, the best option for the security engineer to load onto the device being designed would be the reverse shell endpoint listener (Option D). This tool can accomplish the task with minimal cost, bypass firewalls and NIDS, and is less complex to set up than the other options provided. However, the engineer must take appropriate measures to ensure that the reverse shell endpoint listener is not detected by advanced security measures during the authorized test.
