Can someone hack 100 accounts that's offline?

i think someone hack my account it must of been when i was offline i think but it wasnt me i am agianst hackers modders etc

Or when someone hacks the game. Played with someone who has a score on the russian team that is 100 fold over the number 1 player. So dont tell me people dont hack.

Try playing offline, if it stops freaking out then someone may be hacking your xbox.

Like what systems exactly Monster? And I mean networks. Some are certainly more secure than others, but no network is completely 100% safe. There have been plenty that were thought to be and then proven wrong. Anyone that knows a bit about computers knows
that no network can actually be 100% hack-proof. If someone can design it, someone can hack it. But like I said, when it comes to systems like what MS is running, actually hacking into it just isn't worth the effort when there are methods of phishing that
have already proven successful and barely require any skill at all.

They often are bluffing but there still are many people capable of hacking something that can hack someone's account
