Now nearly eight years old, MAC Freeware Suspicious Package, the tightly focused security tool for Apple Inc's (NasdaqGS: AAPL) OS X hit another milestone this year (in February) now at version 2.0.1.

Crafted by Mothers Ruin, Suspicious Package takes a deep view into installer packages (in the Finder). The bits utilize Quick Look to display the contents of the package, popping up a preview in the Quick Look window. A superb, single purpose security tool for your toolkit.

"Shouldn't I be suspicious of the Suspicious Package package? Yes, we're aware of the ... irony of distributing Suspicious Package as a package, but it's very awkward to distribute it any other way. If you want an alternative, though, there are instructions here. The Suspicious Package package is signed with an Apple-issued “Developer ID” certificate, and so will be recognized as valid by the Gatekeeper feature of OS X. The signer, as displayed by Suspicious Package itself, will be “Randy Saldinger,” which is the real name of the person who writes in the first person plural for Mothers Ruin Software." - via the Mothers Ruin Suspicious Package FAQ
