Just a quick update from from our friends at World of Raids about the current situation regarding circumvented authenticators. It appears there are multiple websites being used for this malware. Be careful of which sites you go to in order to update your addons from; fake website addresses are being used to trick users.
For example, one of the fake sources appears as a "Sponsored Link" right at the top of a Google search. Don't actually visit that site and be sure to warn players asking about addons where to go.
What happens is the fake site will allow you to download a fake copy (did you see fake?) of the WowMatrix AddOn Manager which installs the emcor.dll. This Trojan (Malware.NSPack) can currently be detected by Malware Bytes.
