A script-based threat that spies on Mac users caught the attention of
some security watchers last week.

The malware, which has been dubbed Opener by Mac user groups, can
disable Mac OS X's built-in firewall, steals personal information and
can destroy data. It is not yet a widespread danger, however.

Security experts say those traits are common among the thousands of
online threats targeting Microsoft's ubiquitous Windows operating
system but are virtually unheard of on Apple Computer's Mac OS.

Paul Ducklin, Sophos' head of technology in the Asia-Pacific region,
said that the software, which Sophos calls Renepo, is designed to
affect Mac OS X drives connected to an infected system and that it
leaves affected computers vulnerable to further attack.

Ducklin said Opener disables Mac OS X's built-in firewall, creates a
back door so the malware author can control the computer remotely,
locates any passwords stored on the hard drive, and downloads a
password cracker called JohnTheRipper.
