F-Secure claims to have discovered the first Mac rogue application--MacSweeper.
According to F-Secure, MacSweeper is spyware that closely resembles its Windows cousin Cleanator. Here's how it works:
You install MacSweeper and it proceeds to "clean" your Mac of compromising files. This spyware is so diligent that it ALWAYS finds something to clean. All you have to do is buy the software.

And to make itself look legit, MacSweeper cuts and pastes its description from security vendors like Symantec. These bogus programs aren't anything new, but the fact that one has surfaced on the Mac indicates that Apple's market share has been on a tear.
