Account security concern . Account possibly hacked

I logged into Xbox live this morning everything was normal, so I headed over to call of duty black ops 2 and started playing it, I was put into a hacked lobby on a team deathmatch session. I tried to exit the session but the pause menu was disabled Possibly
by the hacker/modder. There was a few minutes left so I waited until i got to the pre game lobby where I was not able to exit also. The match started again and as soon as it started my gamerscore started rising, achievements for black ops 2 were being unlocked
so I pressed the home button and went back to the xbox live home screen where achievements were still being unlocked. I did not give away my account details to anyone before. I have experienced this before and was banned for 2 weeks I do not want to be banned
again for something that I did not do. Please help answer my query or assist me in my next steps on what to do. Thank you

:)

 

Xbox Live Security Check

Security is kept on the xbox in case people lose their accounts or are being hacked. It is something good that is on xbox.

 

Latest PS3 hack could be the end of the system!

Then why do people constantly get their live accounts hacked? Mind you this has even happened to industry figure head live accounts. There was even some jerk on this forum that got banned for showing a way to hack.


I love the 360 as much as the next guy. But seriously, let's put this myth of "you pay for security or privacy" with Live because that's already been disproven.

And think about it, that kind of thing didn't happen when you could play your 360 games free online. Yet now that you have to pay for that portion all these hacks to get accounts stolen come up. So if you're paying for privacy and security, why is it comprised only after they make us pay?

 

Unfortunately the chances of receiving another suspension or possibly a ban are quite high.

What you should of done is quit the modded lobby straight away by using the guide button on your controller & going back to the dash.

By staying in the modded lobby you have done something against the Coc.

 

I just wanted to add that if this does happen again it is best to power cycle your console to ensure that the mod doesn't follow you back into the game.

 

It's kinda sad that someonelse can get you banned or suspended, I'm just hoping that it's not the case for me. Anyways thanks for the answers really appreciate them
