We are new to Information security and we have a question that we can not figure out how to solve.
We can assume that:
The malware is deployed on an infected laptop that is connected to a network, wirelessly
The attacker is equipped with only a standard laptop (no additional hardware is being used)
The attacker's laptop is not connected to the infected laptop's network
The attacker applies external interception to the infected network.
The question: What is the maximum effective distance from the infected network, that the attacker's laptop can be located? What challenges may arise from locating the attacker's laptop too far from the infected network? Will it damage the extracted message?
Our thought: We can't find a numeric answer to this question, maybe we didn't understand the question. We think the attacker needs to be as close as he/she can, because he/she will sniff packets that have traveled the least amount of routers and therefore it's more reliable.
Could someone please clarify for us how we should approach this question? Where is the mistake?
