Uh, I'm pretty sure that this is nothing to worry about.
1) This "Minecraft Hacked Client" is probably just a hack for Minecraft, for example some sort of PvP hack.
2) If it is, in fact, a way to hack someone else's account, then I've never seen anyone on ECC affected by it before. I bet it's not possible, or at least not likely, for that to happen.
I'm not super knowledgeable about this, since I don't hack/mod Minecraft, but I'm nearly 100% sure that this is nothing to fret about at all.
Oh, and by the way, with your comments about older players rejoining and having to worry about their account being hacked since their stuff is gone: older, rejoining players don't have their stuff because ECC automatically clears your inventory and enderchest after a week of inactivity. I think after a while their money gets cleared too.

*EDIT* Sorry for the double post. If possible, can a mod delete this comment, thanks xP

 

Hacked client means you use a profile, or client, with certain hacks installed on it...

 

I have been affected by a hacked client. I issued a 3 day temp ban on myself. I came back all my chests were unlocked and looted, my bal was gone by 50% and I lost all my max tools.

 

Oh. Then I stand corrected for the moment.

 

wait what?

 

You have reversed my opinion about the accounts of ECC users not being hacked.
Still though, @imtheking444 , Minecraft Hacked Client just means the account is using hacks, not being hacked into.

 

If someone gets into your mine craft account it is probably they found out your password. (Since the username is ign, which I think isn't much security). Hacking into something like a minecraft account just means they can log into the account. If this happens you change your passwords, etc.
Edit* I don't know anything 100% on this talking and yes it's possible but it's not a high chance or percent rate.

 

what

 

Really just dont be stupid and make your password uber obvious?

 

I tried joining the server with hacked clinic once never worked never will.

 

@tommied7 is a girl.

 

That's nice @shrinkwrap4me.

As for this post, hacked clients are generally used to refer to a client which gives you unfair advantages, hence why they are strictly prohibited. Sometimes pople create malicious programs which players think are going to give them such advantages, when in fact they are key loggers or similar and actually are just for the purpose of stealing your minecraft login details.

Bottom line. Any sort of hacked client which gives you an advantage is illegal on ECC, and installing them may be a threat to the security of your minecraft account.
