According to Symantec, a new and malicious worm is spreading (dare I say it?) like wildfire within OpenOffice documents. "The worm can infect Windows, Linux and Mac OS X systems," according to a Symantec Security Response advisory. "Be cautious when handling OpenOffice files from unknown sources."

The worm was first spotted late last month, but at the time, it was not thought to be "in the wild."

Once opened, the OpenOffice file, called badbunny.odg, launches a macro that behaves in several different ways, depending on the user’s operating system.

On Windows systems, it drops a file called drop.bad, which is moved to the system.ini file in the user’s mIRC folder. It also executes the JavaScript virus badbunny.js, which replicates to other files in the folder.

On Apple Mac systems, the worm drops one of two Ruby script viruses in files respectively called badbunny.rb and badbunnya.rb.

On Linux systems, the worm drops both badbunny.py as an XChat script and badbunny.pl as a Perl virus.

Symantec rates the worm as a "medium risk."

That is, only if it is not on your computer

As if the Netscape vs IE vs Firefox weren’t enough to confuse a person, another browser is being thrown into the mix.

Apple is shipping the third version of the Safari WebKit-based browser overseas to compete with the big boys (IE, Firefox, and Opera) and … on Windows no less!

The Mac-only browser has a 5% market share, and it wants to copy what iTunes did, namely, to grow the Mac fanbase.

Apple claims their browser is up to twice as fast as the competition, and the public beta of Safari 3 is being released today as a free download for Mac OS X, Windows XP and Windows Vista.

So, which one are you using?
