Miscreants have created an item of spyware targeted at Firefox users.

The malware poses as an Adobe Flash Player update but in reality its designed to log a user's browsing history, in particular their Google search queries within Firefox. This information is uploaded to a hacker-controlled server.

EBOD-A also has the capability to inject ads into the user’s Google search results pages, Trend Micro warns, which adds that the malware appears to be spreading via forum posts.

The spyware creates a Firefox add-on called "Adobe Flash Player 0.2", which has nothing to do with either Adobe or Mozilla. More on the threat can be found in a write-up by Trend, which includes screenshots, here.

Malware targeting Firefox users is rare but not unprecedented. Strains of malware that latch onto Internet Explorer, Microsoft's Swiss-cheese browser, are much more commonplace. Common IE-related malware trickery involves exploiting unpatched security vulns to download malware onto vulnerable machines via drive-by download attacks. ®
