Intego researchers are warning that a Mac spyware app is now being distributed on popular download sites.

"Dubbed OSX/OpinionSpy, the spyware is distributed through software available on sites including Softpedia, MacUpdate, and VersionTracker, according to Intego, a provider of anti-virus software for Macs," writes The Register's Dan Goodin. "The app isn't contained in the downloads themselves, but rather gets downloaded during the installation process, Intego said."

"Once installed, OpinionSpy scans files and folders on all attached hard drives and regularly sends data in encrypted form to several servers, according to Intego," Goodin writes.
