In the course of explaining 'ji32k7au4a83' ...

the term "pwned" is used. That term is new to me but it apparently it has wide usage throughout the internet (I just don't move in the right internet circles). In the context of this article it refers to someone being the subject of a data breach and possibly having their account(s) compromised. In the more hip parts of the internet, it has a wider meaning.

The correct pronunciation of "pwned" is up for grabs to quote one answer in StackExchange: "Because it originated on the internet recently, is slang, and has no obvious pronunciation, there is no uniform pronunciation for "pwn." I have personally heard native English speakers argue that it should be pronounced like pawn, like pone, and like own. My personal preference is pone; that seems to be the funniest pronunciation."

The Gizmodo article also references a site called "';--have i been pwned?" (yes, that is the title including the quote mark, semi-colon, and hyphens) that specializes in helping people determine if they have in fact been pwned. So, in conclusion, reading this post and the Gizmodo article will serve to inform you in a number of ways:

• Why 'ji32k7au4a83' is a remarkably common password that you should not use (I know you wanted to).
• What being "pwned" means.
• How to pronounce or not pronounce "pwned".
• A source that can be used to find out if you have been "pwned".
