I checked few more resources on google my self and found this very interesting post by Washington Post about new apple script trojan horse that is lurking arround. My early post today (New Apple Trojan AppleScript-THT)

I found this part most interesting by WPost.

Currently, the Macshadows user forum appears to have been wiped clean, both from the Macshadows.com Web site and from Google’s cache. However, Security Fix obtained screen shots of forum postings from the code’s authors, which are sprinkled throughout this blog entry. It appears that development of this malware started back in mid-May.

SecureMac submitted awesome description about this trojan.
