Potential Trojan Account Threat

[Edit:] It seems it has been tracked down, and info provided on how to get rid of it:

-At this point, it seems the easiest method to remove the trojan is to delete the fake Curse Client and run scans from an updated Malwarebytes. Should you still have issues, there is a more manual method that Ressie posted earlier in the thread.

-Thanks to Ressie's efforts, most security programs should be able to identify this threat shortly, if not by the time I type this.

-If you were compromised, follow the instructions here and we'll do our best to set everything right (as we always do).

-For those of you interested in these MitM style attacks, this is the only confirmed case we've seen in several years outside of the "Configuring/HIMYM" trojan in early 2012 that hit a handful of accounts. These sort of outbreaks are annoying, but an Authenticator still protects your account 99% of the time. Stay safe!

[Original post:]
Blizzard Custom Support just posted an alert about a Trojan virus that can compromise accounts even with an authenticator. So far there is no easy way to remove it besides reformatting your system, but Blizzard has posted instructions on what to do if your account has been recently compromised.

The Trojan acts in real time to do this by stealing both your account information and the authenticator password at the time you enter them.

If your account has been compromised recently, I'd recommend looking for the Trojan. It can be identified by creating an MSInfo file and then looking in the Startup Program section of that file for either "Disker" or "Disker64". It will usually appear like this:

Disker rundll32.exe c:\users\name\appdata\local\temp\w_win.dll,dw Name-PC\Name Startup
Disker64 rundll32.exe c:\users\name\appdata\local\temp\w_64.dll,dw Name-PC\Name Startup
We are currently looking for more information on the Trojan. We have not been able to locate any anti-virus programs that will remove it besides just reformatting your system. If you have been recently compromised and find it on your system please reply with the following pieces of information.

Your MSInfo.
A list of any addons you recently installed along with where you got them.
A list of any programs you recently installed along with where you got them.
Any security programs you have run and their results.

For anyone that may not know how to create MSInfo as a file, Blizzard posted the information on battle net website. Look for obtaining system files under the support area to find the information. I'd post a direct link but if memory serves me correctly the forums rules ask us not to.

Which forums? Theirs or ours? If ours, no we don't, not when it's to an official (ie trustworthy) site.

Here is the link with instructions on how to "create an MSInfo file" (what a misleading term, lol):
https://us.battle.net/support/en/art...g-system-files

The WoWI forum rules don't disallow posting links to informational pages, especially links to Blizzard's own website. What the rules do disallow is posting links to off-site downloads -- if you want to post an addon for other people to download, WoWI wants you uploading that addon to the site through the proper channels so it gets run through WoWI's malware scanner etc.

Thanks for the clarification on acceptable links everyone. It also seems they've figured out the issue and our security programs are most likely already on board or will be soon.

How on earth does anyone get fooled by these fake sites? Even my grandma knows how to look at the address bar and tell whether it says "chase . com" or "fdsfu894037q583h24 . login-to . chase . com . cn".
