There's currently a very convincing email scam going around at the moment related to Blizzard's trademark of Cataclysm. World of Raids contributor Postulio tipped us off to it, and I wanted to pass this on to as many players as humanly possible. As you can see by this thread, they've even gone as far as creating a fake "trailer" to build excitement for this email.
However, this is not a real alpha test invite. It prompts you to download a .rar file for the "Cataclysm Installer" which is actually a keylogger. If you've gotten this email, delete it; do not follow the links provided in it. If you've mistakenly taken this as a real invite, run Antivirus software to ensure your computer is clean of any keyloggers and change your World of Warcraft account password immediately.
I would also encourage you to purchase a Blizzard Authenticator if you want added security, or download it for free if you're an iPhone user.
Blizzard never, ever invites random players to alpha tests of their expansions, especially when the expansion hasn't even been announced yet. The likelihood of it actually being in alpha (whatever the name is) is very small. In fact, we don't even know if Cataclysm is even related to World of Warcraft at all yet, so sit tight for BlizzCon, and be sure to ignore these emails. When Blizzard is ready, they'll be sure to let everyone know what Cataclysm is and when players can expect to get their hands on it.
