I don't want to go into too much detail, although I'll fill in the blanks if it becomes common knowledge. Basically, since 1.04 more and more high level players ranked on the ladders have noticed items going missing from individual characters. They claim that their b.net account passwords have not been hacked. The main argument is they had other characters on their accounts with much more valuable items who didn't get touched, only the ladder character got robbed. I've seen a report that explains that all someone needs is the name of your character to get access to your character's items. The means of doing this seems plausible to me, but has not been confirmed by trusted sources yet. In any case, the following precautions aren't a bad idea: 1. If you have a character who's name might be well known outside of people you trust, consider muling your best items to a different character (with a non-obvious name) for a while. 2. For characters that you continue to keep good gear on, don't advertise your "wealth" in public chat channels. It was never nice to brag, but now there might be a consequence. 3. If you frequent the trading channel, consider doing your messages from an empty character / account, and changing to the character with the items in question only when you have an agreed upon trade. 4. Try not to tick people off in games. Chances are if they threaten to "hack your account" the threat might not be an idle one. I hope this is a hoax and don't mean to alarm people. Your realms characters at the moment aren't as secure as you thought they were. Blizzard representatives were made aware of the problem today and are looking into it. Better safe than sorry though.
