Hi, I have a Huawei Wi-Fi type HG523E home gateway and I'm suspicious over my national telecom company technician being hacked. I see my MAC address from the label device is different from when I detect with other third party software. Then sometimes, a few days ago, when I type Google.com but the traffic directs me to Google.co.th. I think it might be a MITM attack but I'm not sure how to prove it with a forensic method or another method so I can bring it to court as proof of illegal spying from the technician or the telecom company. Is there a way I can defense it with some encryption method? My OS is Windows 7. Thanks in advance.
