I really doubt that you will get banned by using Wireshark. Its a packet sniffer that reads your network card activity. It has nothing to do with Cod Ghost directly
A friend of mine is 100% sure that he was banned from BO2 by using Wireshark. And I hooked some Winsock functions into BO2 and "Disconnected from Steam." ._.
And I know that this won't most likely get anyone banned but since some of you already started to cheat and I just bought the game yesterday, I just don't want to take the risk of getting banned again.
